Le fer-blanc est, de loin, le matériau le plus utilisé pour la fabrication d'emballages, notamment pour la confection des boîtes de conserves. Ce métal, que plus de cent ans d'usage ont consacré, n'est pas détrôné et nous ne croyons même pas qu'il soit sur le point de l'être.

Orthopterological notes III : The Phyllophorinae (Orthoptera, Tettigoniidae) in Mr. Willemse's Collection (Eijgelshoven, Limburg) and in the Natuurhistorisch Museum, Rotterdam
Provedor de dados: 16
Autores: Jong, C. de.
In 1946, after the war, I had the opportunity again to visit my friend Mr. C. Willemse, and to study the Phyllophorinae in his collection. At the same time I could examine two specimens from the Rotterdam Museum, belonging to the subfamily, which had been sent to him for identification. Especially these last mentioned two specimens are very interesting, the one being the still unknown ♂ of Sasima areolata Bol., the second a somewhat aberrant ♀ specimen of Phyllophora keyica Brunner v. Watt. For the literature I may refer to Orthopterological Notes II (De Jong, 1946). The sequence of the species is according to Karny (1924) Sasima spinosa Brunner von Wattenwyl Mr. C.

Revision of the lichens of the Netherlands. I. Parmeliaceae
Provedor de dados: 16
Autores: Maas Geesteranus, R.A.
It was shown that the oldest Dutch lichen herbarium known was that of H. Boerhaave dating as far back as the end of the 17th or the beginning of the 18th century. After that there was a long spell of inactivity, until from about 1835 onward the florists again started making herbaria. From the end of the nineteenth century the interest flagged again, and collecting was done by very few people. The first publications which are known to deal with Dutch lichens mentioning the locality do not date back farther than the 17th century, the work by C. Pilleterius (1610) being the oldest one. Those earliest publications comprised but a very small number of lichens, presumably because of few of them the officinal application (the main impetus of getting acquainted...

On fossil and prehistoric remains of Tapirus from Java, Sumatra and China
Provedor de dados: 16
Autores: Hooijer, D.A.
The tapir is an extremely rare element in the fossil Mammalian fauna of Java. In the enormous collection of fossil teeth and bones brought together in this island by Eug. Dubois in the years 1890 to 1900, the tapir is represented only by six teeth, originating from three localities in the Kendeng Mts., viz., Kedoeng Broeboes, Kedoeng Loemboe, and Kebon Doeren. Previous to his researches in Java, Dubois collected teeth in a number of caves in the Padang Highlands. In this Sumatran collection Tapirus is not uncommon. We possess one hundred and twenty complete, and a still larger number of broken teeth. Half of this collection originates from three caves, viz., the Lida Ajer cave near Pajakombo, the Sibrambang cave, and the Djamboe cave near Tapisello. The...

Autores: Bruijning, C.F.A.
The Blattid fauna of Celebes, the Moluccas, and New Guinea, a region which from a zoogeographical point of view forms an important area of transition, is still insufficiently known. Moreover the literature on the Blattids of this region is scattered in various papers which made it desirable to give a general survey of the hitherto known species of the group from Celebes, the Moluccas, and New Guinea. The present paper deals with the material of Blattidae from the region mentioned above contained in the Leiden and in the Amsterdam museums. I am indebted to Prof. Dr. H. Boschma and Dr. H. C. Blöte of the Rijksmuseum van Natuurlijke Historie at Leiden, and to Prof. Dr. L. F. de Beaufort and Mr. J. B. Corporaal of the Zoological Museum at Amsterdam for placing...

The MS Flora of the Bismarck Archipelago, by Father G. Peekel has, fortunately, escaped being destroyed during World War II. It is a large work in which over 1000 species are described each one accompanied by an accurate line drawing. Father Peekel shared emprisonment with the Japanese at Rabaul during the war. He is now back on his post and has taken the MS flora with him. A microfilm of it was made and entrusted to the Missions Board at Sydney. A mimeographed tentative program for the preparation of a Flora of China prepared by doctors E.H. Walker and H.H. Bartlett was received August 1947.

Autores: Koster, Joséphine Th.
After a paper had been published i.a. on the species of Stevia of the collection mentioned in the heading¹) another Stevia from the same collection came into the author’s hands. It proved to be new. The American genus Stevia has been treated in local revisions by B. L. Robinson (in Gray Herb. Harvard Univ. V, 90, 1930, 36—159; 96, 1931, 28—49; 100, 1932, 20—69). Its floral characters are fairly uniform, but the pappus shows a great diversity. The 5 achenes in a head do not mature at the same time. The genus Stevia seems to have its greatest development in Bolivia, where it is represented by 44 species. The next representation is in Peru with 24 and in Argentina with 23 species.

Zoological notes from Port Dickson : I. Amphibians and reptiles

Autores: Brongersma, L.D.
During the time that I was stationed at Port Dickson (State of Negri Sembilan) on the west coast of the Malay Peninsula, a small zoological collection was made. The specimens were brought to me by the personnel of different units of the Royal Netherlands Forces, while I am also indebted to Major C. Rae, RASC, for some interesting specimens. Nearly all specimens belong to common species. However, this area has not been studied so very extensively and therefore, it seems worth while to place these species on record. Unless otherwise stated the specimens are from the strip of country along the coast road to the south of Port Dickson to about ten miles from the township. Where no unit is mentioned, the specimens have been collected by personnel of my own unit...

Zoological notes from Port Dickson : II. A small collection of fishes from Malaya
Provedor de dados: 16

During the stay of the Nica-detachment at Port Dickson, Malaya, in March 1946, a small collection of fishes was made, which was presented by Major Dr. L. D. Brongersma to the Rijksmuseum van Natuurlijke Historie at Leiden. Besides these fishes from Malaya, two specimens of flying fishes from the Indian Ocean were presented. The collection from Port Dickson was pretty small, 45 specimens in total, belonging to 25 species. It gives therefore by no means an idea of the fishfauna of Malaya. The fishfauna of the Westcoast of Malaya is still imperfectly known, so even this small collection can contribute to the knowledge of this fauna.

Traces of ancient Dichotomies in angiosperms. (A contribution to our Knowledge of Phyllospory and Stachyospory)
Provedor de dados: 16
Autores: Hammen, L. van der.
It is a generally accepted concept nowadays that dichotomy is the most primitive type of ramification in land plants. Recently Lam (1948) briefly reviewed the literature of this subject in the light of the telome theory. He recalled that the dichotomies of fern leaves are to be regarded as homologous to the dichotomies of stems in more primitive plants and enumerated a number of more or less haphazardly collected cases in higher plants, of which the most probable interpretation is that they are traces of such ancient dichotomies, betraying their original relation to a branch system. In his paper, Lam discriminated between such traces in vegetative and in reproductive parts and he arrived at the provisional conclusion that traces of ancient dichotomies in...

Notes on the Spiderfamily Hahniidae
Provedor de dados: 16
Autores: Hammen, L. van der.
Material collected by Mr. J. van der Drift and by myself in the National Park "De Hooge Veluwe", situated near Hoenderloo in the province Gelderland, led to some notes on the nomenclature and to supplementary descriptions of some Hahnia species. The main works dealing with European Hahniidae are Dahl (1937) and Simon (1937). The descriptions and figures in Dahl (1937) are very good and it is rather easy to recognise the species by the sexual organs. Unfortunately the nomenclature is partly wrong. Now the nomenclature in Simon (1937) for the greater part is correct, but the descriptions are sometimes incomplete. In the following I tried to clear up some points.

The identification of wood species with the aid of the Hollerith system

The International Association of Wood Anatomists in the early years of its existence has undertaken to standardize the nomenclature used in describing woods. Later the classes of dimensions have been added thereinto. In the same way it should be possible now to standardize one or two identification methods. Universal schemes in the first place will fit for this purpose. In the introduction it is explained which requirements should be fulfilled in such schemes. The advantages and drawbacks of an English and a Dutch identification method are compared mutually. It is suggested, that a procedure according to the Hollerith system will allow of a synthesis of both methods mentioned, thus combining advantages and eliminating their drawbacks.

The dorsal hairs and partly those on the legs and antennae are long and not thicker than in other Macrosiphoniella's but their apex is flattened and ramose, sometimes bifid. The ultimate rostral segment is Fig. 1. Ramitrichophorus janckei (Börner), apt. viv. fern.: a, siphunculus; b, cauda; c, last rostral segments.

Revision of the fishes collected by Burger and Von Siebold in Japan
Provedor de dados: 16
Autores: Boeseman, M.
INTRODUCTION The collections made by Burger and Von Siebold during the second quarter of the previous century, in the neighbourhood of Nagasaki, were so extensive that they gave Temminck &amp; Schlegel the opportunity to build the foundation for the knowledge of the Japanese ichthyofauna. In her publication "'s Rijks Museum van Natuurlijke Historie, 1820-1915", Dr. A. Gijzen states: "Burger sent among others fishes"; "25 December 1832 Temminck gives him a list of the desired species of animals." As she further states, Burger's position in Japan is not quite clear; in a letter from 9 November 1839, Temminck writes to the Minister that he knows Burger as a collector only, but that he knows no further particulars about him. Burger's name has been mentioned in...

The South American Nematognathi of the museums at Leiden and Amsterdam
Provedor de dados: 16
Autores: Stigchel, J.W.B. van der.
The collections of the South American Nematognathi in the Rijksmuseum van Natuurlijke Historie at Leiden, referred to in this publication as "Museum Leiden", and of those in the Zoölogisch Museum at Amsterdam, referred to as "Museum Amsterdam", consist of valuable material, which for a very important part has not been studied yet. I feel very much obliged to Prof. Dr. H. Boschma who allowed me to start with the study of the Leiden collections and whom I offer here my sincere thanks. At the same time I want to express my gratitude towards Prof. Dr. L. F. de Beaufort, who has been so kind to place the collection of the Zoological Museum at Amsterdam at my disposal. Furthermore I am greatly indebted to Dr. F. P. Koumans at Leiden for his assistance and advice...

On the distribution of Bidder's organ in Bufonids
Provedor de dados: 16
Autores: Dubois, R.
It is a well-known fact that Bidder's organ is an undeveloped ovary. It is found in all adult male and in many adult female as well as in all juvenile male and female specimens of Bufo-species, and it is situated between the fatbody and the gonad. The fact that Bidder's organ is a potential ovary is not only derived from its morphology, but has also been proved experimentally by Harms (1923) and Ponse (1924), for after castration of male toads and after ovariectomy of female common toads (Bufo vulgaris Laur. (= B. bufo (L.)) Bidder's organ may develop into a normally functioning ovary. In 1931 Stohler compiled our knowledge concerning the distribution of Bidder's organ in the Bufonidae; in addition the occurrence of the organ was described in several other...

Is Zosterops javanica elongata inderdaad goed onderscheidbaar van Zosterops javanica frontalis?
Provedor de dados: 16
Autores: Hoogerwerf, A.
In 1913 (Nov. Zool., vol. XX, p. 366) beschreef Stresemann naar aanleiding van op Bali verzameld materiaal (2 ♂♂ en 2 ♀♀) een nieuwe ondersoort van Zosterops javanica, door hem elongata genoemd, op grond van een langere snavel. Stresemann publiceerde de volgende diagnose: „In der Färbung stimmen die Balivögel vollkommen mit O. j. frontalis (Rchb.) überein; sie unterscheiden sich jedoch durch auffallend längere Schnäbel." Zosterops javanica frontalis werd reeds in 1852 afgesplitst door Reichenbach (Handb. der Orn., Meropinae, p. 94, pl. 463), terwijl de nominaatvorm in 1821 (Trans. Linn. Soc. London, vol. XIII, p. 156) door Horsfield werd beschreven. Als verspreidingsgebied van deze laatste wordt genoemd (Chasen's Handlist of Mal. Birds) Midden-Java,...

A new system of the Cormophyta
Provedor de dados: 16
Autores: Lam, H.J.
Some time ago I proposed elsewhere (1) a new system of the Cormophyta. Since the periodical, whose hospitality was my privilege, may not reach many taxonomists who still may be expected to be interested in the proposal, I deem it justified to briefly review the results at which I arrived in the present journal; and this will give me an opportunity to explain one or two points of a nomenclatural nature which, it seems to me, were perhaps somewhat insufficiently elucidated in the paper quoted. As a matter of course, for details as well as for the full argumentation of my views I have to refer to that publication.

In 1776 beschreef P. L. S. Müller (Syst. Nat.

Von den Arten der beiden Subsektionen Odorata und Sparsiflora wissen wir schon aus der Monographie, dass sie sich nicht scharf voneinander abgrenzen lassen. Damals wagte ich das nur vage auszusprechen, aus Zweifel, nicht genügend Material gesehen zu haben und aus Rücksicht auf die vielen von ältern Autoren beschriebenen Arten, die ich dort nicht weiter als auf einen Drittel zu reduzieren wagte. Die erneuten Untersuchungen haben das Ineinanderfliessen aller Arten dieser beiden Subsektionen so vollkommen bestätigt, dass ich mehr denn je von der Richtigkeit des in der Monographie eingesehlagenen Weges und der dort angedenteten Anffassung überzeugt bin.

Provedor de dados: 16
Autores: Holthuis, L.B.
The study of the older literature on Crustacea, from Linnaeus (1758) to H. Milne Edwards (1837), has been much neglected by modern carcinologists. A result of this is that many wrong names at present are used, especially for European species. The European species namely were most extensively studied by the older authors, while moreover in the middle of the previous century handbooks on the carcinological fauna of several parts of Europe were published (for instance Bell's (1844-1853) "A History of the British stalk-eyed Crustacea", and Heller's (1863) " Die Crustaceen des südlichen Europa"), which for many authors made a consultation of older works superfluous. It is astonishing to note how many names at present are used incorrectly for species of the...

Flora of Java. Dr C.A. Backer has been working towards the composition of a Dutch-written Flora of Java since about 1903, at first in Java, and onwards of 1931 in Holland. When the war started it was thought safer to mimeograph the MS. as far as it was finished, in order to save the writers’ labours against the chance of complete destruction by bombing or other causes. Prof. Dr H.J. Lam managed to get a number of subscribers and funds for a mimeograph edition. This constitures the ”Nooduitgave” (emergency edition) in which up till now 120 families have appeared in 7 folio volumes. The edition was limited to ca 25 copies. It is the intention to edit 2 volumes more, and then stop it. Circumstances necessitate the printed edition to be written in English to...

After some preliminary plans in 1932, and in 1936, a more definite scheme for a modern Flora of Malaysia was composed in 1939, forming part of the reorganization of the Botanic Gardens, Buitenzorg, Java. This was approved of by the Netherlands Indian Government, and the National Council at Batavia. Necessary preparations for this ambitious scheme had started as early as 1930, consisting of the preparation of card indices, and directing the aim of expeditions in the years 1930 – 1940 to neglected regions in order to fill up gaps in our botanical knowledge and collections.

A influência dos pigmentos amarelo -laranja de vários alimentos na coloração da gema de ôvo de galinha
Provedor de dados: 43
Autores: Graner,E. A.
The effect of different feeds in comparison with that of maize grains on the egg yolk color was observed. It was found that deep orange and yellow orange maize give satisfactory coloration to the yolk, respectively orange and yellow. The most intense color was observed when green feed was used in combination with deep orange maize. Green feeds as chicory, alfafa, cabbage, welsh onion and banana leaves and alfafa or chicory meal proved to be good in giving orange color to the yolk. Yellow yolk was obtained when Guinea grass or carica fruit were used in the ration. Carrot and beet without leaves did not give satisfactory color to the egg yolk. The observations with other feeds are being continued.

Autores: Jardim,Walter Ramos.
Examinando 201 pintos de um dia da raça Rhode Island Red, de rebanho selecionado pela postura e considerando diversos caracteres, principalmente os relacionados com a côr da penugem, conseguimos acertar em 197, numa proporção de 98,01%, não relatada da bibliografia que conhecemos. Julgamos como mais importantes, os seguintes caracteres : mancha clara na asa notada em 100% dos machos e 6,30% das fêmeas; o anel claro na perna ocorreu em 91,80% dos machos e 3,70% das fêmeas. Estas duas particularidades, sòmente, permitem separação de sexo superior a 96%. O sinal junto ao ângulo posterior do olho foi observado em 95,10% das fêmeas e 36,70% dos machos; ponta da asa escura não ocorreu em um macho sequer, mas em 53.20% das fêmeas; ponta da asa clara foi notada em...

Análise do tamanho e da forma do ôvo em galinhas das raças Rhode Island Red e Light Sussex e do híbrido entre essas duas raças
Provedor de dados: 43
Autores: Graner,E.A.; Trivelin,A. P.
Size and shape in eggs of Rhode Island Red and Light Sussex breeds and in the hibrid Rhode x Sussex were studied. These characters are influenced by quantitative genes. Major and minor diameter were used for estimating size of the eggs and the ratio minor/major diameter for shape indice. It was found, in the material analyzed, that: a) the eggs laid by the sa- me chick are pratically uniform; b) the correlation coeficient between major and minor diameter is weak; c) Rhode Island Red has short eggs than Light Sussex; d) short eggs is dominant on long eggs; e) egg shape is the same in Rhode Island Red and Light Sussex breeds and different in the hibrid, which has rounder eggs than the breeds.

Os pigmentos amarelo-laranja do grão de milho como precursores da vitamina a na alimentação dos pintos
Provedor de dados: 43
Autores: Graner,E. A.; Torres,A. P.
A presente experiência foi realizada afim de se constatar a influência de dois tipos de milho comerciais, com grãos coloridos de amarelo-laranja, como precursores de vitamina A no crescimento de pintos. Um deles, denominado "Cateto", duro, de côr laranja muito forte e outro, chamado "Armour", dente, de coloração amarelo-laranja. Para testemunha foi empregado o milho "Cristal", duro e branco. Uma análise dos pigmentos dos dois tipos de milho com gráos coloridos mostrou que o milho Cateto, com grãos de coloração laranja forte, tem aproximadamente o dobro de pigmentos, tanto total como quanto a parte ativa em relação à vitamina A, quando comparado com o milho dente amarelo-laranja. Três lotes de pintos de 3 semanas foram utilizados, cada um recebendo a mesma...

A determinação dos números de indivíduos mínimos necessários na experimentação genética

Autores: Brieger,F. G.
The main object of the present paper consists in giving formulas and methods which enable us to determine the minimum number of repetitions or of individuals necessary to garantee some extent the success of an experiment. The theoretical basis of all processes consists essentially in the following. Knowing the frequency of the desired p and of the non desired ovents q we may calculate the frequency of all possi- ble combinations, to be expected in n repetitions, by expanding the binomium (p-+q)n. Determining which of these combinations we want to avoid we calculate their total frequency, selecting the value of the exponent n of the binomium in such a way that this total frequency is equal or smaller than the accepted limit of precision n/pª{ 1/n1 (q/p)n +...

Uma raça cromossômica natural de Tityus bahiensis (Scorpiones-Buthidae)
Provedor de dados: 43
Autores: Piza Jor.,S. de Toledo.
A natural chromosomal race of Tityus babiensis (Scorpiones Buthidae) is described in the present paper. Five males and seven females received from St. Joaquim, State of S. Paulo, gave the following interesting results: All the spermatogonia of the five males were provided with 9 chromosomes of different sizes. All primary spermatocytes showed at metaphase one independent bivalent of normal shape and a complex group formed by 7 chromosomes which have exchanged parts. Some of the chromosomes associated in the complex group, to Judge by their behavior, were composed of fragments of three different chromosomes, being thus paired with three other members of the compound group. The manner in which all the 7 components of the group have paired with each other...

Interessante comportamento dos cromossômios na espermatogênese dp escorpião Isometrus maculatus De Geer
Provedor de dados: 43
Autores: Piza Jor.,S. de Toledo.
Having had the opportunity of studying a male of the species Isometrus maculatus De Qeer (Scorplones, Buthidae) the author was able to observe one of the most interesting anomalies hitherto met with in his investigations on Scorpions. This anomaly consisted in the formation by the primary spermatocyte metaphase chromosomes of a complex group of eight elements, and two independent pairs. As it is clear, the octovalent group resulted from tranlocations involving the members of four chromosome pairs. Since aside the compound group two independent bivalents were always present, 12 was estabilished as representing the diploid chromosome number of the individual, what was soon confirmed by the counts in the spermatogonia. This peculiar behavior of the...

Comportamento dos cromossômios no gênero Hypselonotus (Hemiptera -Coreidae)
Provedor de dados: 43
Autores: Castro,G. P. de.
The three species studied have 19 chromosomes, being one heterochromosome, one pair of microchromosomes and 8 pairs of autosomes. The microchromosomes of Hypselonotus fulvus are amongst the largest we know. During the synizesis, in Hypselonotus fulvus, we can see in several strands that scape from the chromatic knot a place in which they are widley open. As, in that phase the chromosomes have both ends converging to the same place, the openings suggest a side-to-side pairing of the chromosomal threads. The tetrads are like that studied by Piza (1945-1946). The bivalents are united side by side at their entire length. The unpaired part at the midle of the bivalents gives origin to the arms of the cross-shapede tetrads. The chromosomes have a kinetochore at...

Verificou-se ser mais precoce no desenvolvimento, mais pesada, de carne mais tenra, de maior intensidade e menor persistência de postura, de menor fertilidade, do maior precocídade de postura, de maior predisposição ao choco e de maiores ovos. Apresenta boas qualidades de adaptação e criação que a tomam muito recomendável para as pequenas criações caseiras ou dos sitios, no mesmo sistema em que é geralmente criada na Inglaterra. Só excepcionalmente convirá a uma granja industrial preocupar-se com sua criação em larga escala.

Autores: Jardim,W. R.; Trivelin,A. P.
A test was conducted at Poultry Department of "Luiz de Queiroz" School of Agriculture to prove the effect of green feed on egg production. One hundred Rhode Island Red hens at plain laying period were divided in ten pens. The lot A was constituted of pens 1 to 5 and the lot B of pens 6 to 10. During 16 days the pens 1 to 5 did not receive green feed and the pens 6 to 10 received it with abundance. After and for a period of 30 days the situation was inverted. The analysis were made considering, a) the production of all chickens and b) discarding the chickens with irregular laying. In both cases the results were statistically insignificant, proving that green feed did not improve egg production.

Autores: Piza Jor.,S. de Toledo.
Lutosa brasiliensis, an Orthopteran Tettigonioidean belonging to the family Stenopelmatidae is referred to in this paper The spermatogonia are provided with 15 chromosomes, that is, 7 pairs of autosomes and a single sex chromosome. One pair of autosomes is much larger than the rest, two pairs are of median sized elements, and four pairs are of small ones. The daughter sex chromosomes show at anaphase great difficulty in reaching the poles, being left for a long while in the region of the equator where they are seen stretched one after the other on the same line or lying side by side in different positions. When the spermatogonium divides each daughter cell gets passively its sex chromosome. Though slowly, the sex chromosome finishes by beins enclosed in...

Dissecando o GEN
Provedor de dados: 43
Autores: Piza Jor.,S. de Toledo.
In thee present paper the classical concept of the corpuscular gene is dissected out in order to show the inconsistency of some genetical and cytological explanations based on it. The author begins by asking how do the genes perform their specific functions. Genetists say that colour in plants is sometimes due to the presence in the cytoplam of epidermal cells of an organic complex belonging to the anthocyanins and that this complex is produced by genes. The author then asks how can a gene produce an anthocyanin ? In accordance to Haldane's view the first product of a gene may be a free copy of the gene itself which is abandoned to the nucleus and then to the cytoplasm where it enters into reaction with other gene products. If, thus, the different...

Autores: Torres,A. Di Paravicini.
Este trabalho foi feito afim de determinar uma hipotética correlação existente entre a forma do ôvo e o sexo do pinto. Dois métodos foram utilizados. No primeiro considerou-se apenas a "ponta" do ôvo, dividindo-se um lote de 1100 ovos em dois grupos, um considerado ponteagudo e outro arredondado. Os resultados totais mostraram a nenhuma influência da forma da ponta na determinação do sexo, isto é, a falta de correlação era completa. No segundo método, determinou-se a média da relação entre a largura e o comprimento do ôvo, e adotou-se essa medida como linha divisória de dois grupos : um de ovos grossos com 223 ovos e outro de ovos finos, com 183 ovos. A relação sexual foi respectivamente de 38.60 e 37.07 o que mostra a falta de correlação. Os dez ovos mais...

Autores: Moreira,Sílvio; Gurgel,J. T. A.; Arruda,Lineu F. de.
The studies on polyembryony in Citrus reported in this paper show that there is a great variability in the degree of polyembryony among the seeds, fruits and trees of a same form or variety of Citrus. Seeds from different crops of the same plant also show considerable variation in the degree of polyembryony. In order to obtain reliable data on the degree of polyembryony in Citrus the samples for study should include a great number of seeds taken from several fruits of different trees. Since there is a yearly variation on the degree of polyembryony it was found necessary to study samples from several crops. The average number of embryos was determined by direct examination of individual seeds. Determinations based on the number of plants developed from...

In spite of the polymorphism of Phormium has long been known, no systematic attempt has been made until now to study comparatively the agricultural value and fiber quality of the varieties. This paper is concerned with preliminary results about leaf yield, fiber-content, und general growth of six varieties, of Phormium tenax Forster including a detailed fiber analysis. It is concluded that the varieties have shown strong differences in plant development and fiber qualities, suggesting that some of them would be much more suitable for the improvement of existing areas, and the establishment of new ones on a commercial basis.

A severidade de corte no sisal e analise tecnológica da fibra

Autores: Medina,J. C.; Correia,F. A.
In this paper it is presented a detailed fiber analysis of leaves of twenty mature sisal plants taken from four positions on the plant: 1) first developped leaves (75°); 2) leaves usually cut for fiber extraction (50°) ; 3) leaves adjacent to the central bud (25°) ; and 4) young leaves not yet unfolded from the central bud (0°). The results herein reported are against the prevailing opinion that the sisal leaf only matures after it has unfolded from the central bud. Neither the physical nor the chemical fiber characteristics were adversely affected even if cutting was carried out up to the very young leaves. This practice, however, cannot yet be advised, as it desirability also depends on the effects of the severe cutting upon the subsequent rate of growth...
