Etiología, histopatología y control de la muerte descendente de injertos de zapote mamey (Pouteria sapota (Jacq.) H. E. Moore &amp; Stearn) en Guerrero, México
Provedor de dados: 32
Autores: Tovar Pedraza, Juan Manuel.
La muerte descendente de varetas injertadas de zapote mamey es el principal problema durante la propagación vegetativa de este frutal en viveros comerciales en Guerrero, México. Lasiodiplodia theobromae, identificado cultural, morfológica y molecularmente, se asoció con este problema en 97 % de los aislamientos obtenidos de  varetas necrosadas. Se realizaron pruebas de patogenicidad en varetas injertadas de la selección “El Mexicano”. Las varetas mostraron muerte descendente, caracterizada por secamiento gradual con agrietamiento de la corteza del ápice a la base y crecimiento micelial externo y en la unión del injerto. Picnidios abundantes se observaron en  peridermis y cicatrices foliares. El estudio de patogenicidad confirmó a L. theobromae como el...

Provedor de dados: 69
Autores: Seyring,Martina; Ewald,Aloma; Mueller,Anke; Haensch,Klaus-Thomas.
In the present study we examined the possibility of propagating different Cyclamen species (C. africanum Boiss. and Reut., C. cilicium Boiss. and Heldr., C. coum Mill., C. hederifolium Ait., C. persicum Mill., C. purpurascens Mill.) including some of their subspecies and cultivars in vitro using explants of adult plants. For this purpose two protocols have been applied to eleven genotypes combined with mostly four explant types (placentas with ovules, leaves, petioles and peduncles). The use of these protocols has given rise to either somatic embryo-like structures and/or adventitious shoots in all genotypes. This way it was possible to propagate each of the examined genotypes in vitro using explants of adult plants in a time less than one year. These...

Influence of 2,4-D and BAP on callus growth and the subsequent regeneration of somatic embryos in long-term cultures of Pelargonium x domesticum cv. Madame Layal
Provedor de dados: 69
Autores: Haensch,Klaus-Thomas.
This long-term study demonstrates for the first time that it is possible to propagate embryogenic cultures in pelargoniums and to subsequently initiate the differentiation of embryos using the cultivar Madame Layal (Pelargonium x domesticum). Propagation of callus was only possible with combinations of 2,4-dichlorophenoxyacetic acid (2,4-D) and 6-benzylaminopurine (BAP), which gave rise to embryos from the primary culture stage on. However, the propagation of cells, as well as the differentiation of embryos, was inhibited by a continuous application of these growth regulators. For this reason, a long period on medium lacking growth regulators was necessary before the differentiation of embryos occurred again. The consequences for improving the propagation...

ABSTRACT Increasing potato yield while saving natural resources is a challenge for all those involved in the potato production chain. A field experiment was carried out in order to evaluate the effect of different levels of fertilization, mass of seed tubers and the water regime on the production of potato cv. Orchestra. We tested fertilization methods (F1= conventional fertilization; F2= fertigation according to the rate of absorption by the crop; F3= fertigation split into 3 applications), seed tuber mass (ST1= &lt;50 g; ST2= &gt;50 g), and water regimes [WR1= 50%; WR2= 100% replacement of crop evapotranspiration (ETc)]. The study was conducted using a split-plot randomized block design, with fertilizers in the plot and seed tuber mass in the subplot,...

Autores: May,André; Bovi,Odair A; Maia,Nilson B; Moraes,Andrea RA de; Pinheiro,Mariane Q.
A trial was carried out in Campinas, Brazil, from August 2005 to August 2006, in order to analyze the effect of two propagation methods (seeds and cuttings) on the development of Pfaffia glomerata (Spreng.) Pedersen. The experimental design was a completely randomized block, with five replications, and two methods of plant propagation. Plant height, aerial part dry mass and root dry mass were evaluated. Plants propagated from cuttings showed greater accumulation of dry mass on the aerial part. Root dry mass accumulation curves showed an exponential pattern, and at the end of the experimental period, the average of roots dry mass for both treatments were similar, up to 349,65 g plant-1.

Autores: FUKUDA, W. M. G.
Variedade de mandioca e um dos principais componentes para o desenvolvimento do sistema produtivo dessa cultura, alem de constituir uma tecnologia que nao implica em custos adicionais para o produtor. Apesar da mandioca apresentar um alto potencial produtivo, estimado por COCK (1974) em 90 t/ha/ano, a produtividade nacional esta em torno de 12 t/ha. Um dos fatores que tem contribuido para a baixa produtividade desse cultivo no Brasil, e o uso de variedades com baixo potencial produtivo. A demanda por novas variedades de mandioca vem crescendo constantemente, a medida que surgem novas alternativas de uso pelo produto, bem como a expansao de novas fronteiras agricolas para o plantio dessa cultura. Para atender essas demandas, e importante definir-se as...

A importância das sementes na disseminação das doenças de plantas.
Provedor de dados: 14
Autores: CHOUDHURY, M. M.
As sementes, estacas, bulbos, tubérculos, etc., são órgãos de propagação vegetal e eficientes veículos de disseminação de fitopatógenos em campos agrícolas. Como as sementes contribuem com aproximadamente 90% para a propagação das culturas, muitos fungos, bactérias, virus e alguns fitonematóides podem apresentar-se associados as mesmas, causando severos danos as culturas. Estes fitopatógenos, em condições favoraveis, sobrevivem nas sementes de um ano para outro; ou por período mais longo durante o armazenamento. São apresentados no trabalho os danos causados por sementes infectadas ou contaminadas, os meios de disseminação de fitopatógenos pelas sementes e como evitar a introdução de doenças na região. Com relação a colheita, dois aspectos básicos devem...

Essais de propagation in vitro de virus de type herpès infectant les mollusques bivalves marins et contribution à l'étude des interactions hôte-virus
Provedor de dados: 5
Autores: Deniau, Stephane.
Des infections à virus de type herpès sont rapportées chez différentes espèces de mollusques bivalves, à travers le monde. Elles sont associées à de fortes mortalités de larves et de juvéniles, pendant les périodes chaudes de l'année. Ce type d'infection virale a été observé sous forme de cellules anormales au moyen de la microscopie photonique et de particules enveloppées à conformation icosaédrique, en microscopie électronique à transmission (MET). Aujourd'hui, il est possible de diagnostiquer la présence du virus grâce à des outils moléculaires tels que la polymérisation en chaîne (PCR) ou l'hybridation in situ (HIS). Cependant, l'absence de lignées cellulaires homologues représente une difficulté majeure. En effet, la recherche d'effet cytopathogène et...

Autores: Lurton, Xavier.
Sound waves are the only practical means of remote investigation and transmission in seawater. All along the XXth century, underwater acoustics became one of the major technologies used for exploration and exploitation of the oceans for scientific, industrial, or military purposes. It is nowadays able to play, inside the oceans, the roles devoted to radio and radar in atmosphere and space, and is widely employed in the fields of navigation, fisheries, defence, oceanography and ocean engineering. This book presents, in a clear and concise way, the basic physical phenomena governing underwater acoustical waves, the general features of sonar systems, and an overview of their applications.

Genetics evaluation of minicuttings rooting of Eucalyptus cloeziana provenance
Provedor de dados: 190
Autores: Oliveira, Leandro Silva; Dias, Poliana Coqueiro; Almeida, Marcílio de.
Cloning of superior genotypes is presented as an alternative to increase forest productivity, because it allows capturing the genetic gains (additives and non-additives) from forest breeding. Early selection based on characteristics related to adventitious rooting may be important for breeding programs for recalcitrant species, like Eucalyptus cloeziana F. Muell. The objective of this work was to perform the genetic evaluation of E. cloeziana individuals based on adventitious rooting. The genetic control of adventitious rooting of 52 E. cloeziana trees was analyzed by variance components estimation and predicts breeding values. We used REML/BLUP procedure (estimation of variance components - Reml and prediction of breeding values - Blub). The variables...

Nutrition and adventitious rooting in woody plants
Provedor de dados: 190
Autores: Pereira, Fernanda Bortolanza; Bandeira Peres, Fabiana Schmidt.
Vegetative propagation success of commercial genotypes via cutting techniques is related to several factors, including nutritional status of mother trees and of propagation material. The nutritional status determines the carbohydrate quantities, auxins and other compounds of plant essential metabolism for root initiation and development. Each nutrient has specific functions in plant, acting on plant structure or on plant physiology. Although the importance of mineral nutrition for success of woody plants vegetative propagation and its relation with adventitious rooting is recognized, the role of some mineral nutrients is still unknown. Due to biochemical and physiological complexity of adventitious rooting process, there are few researches to determine de...

Germinação de sementes de Matelea maritima (Jack.) Woods (Asclepiadaceae)
Provedor de dados: 88
Autores: CUZZUOL,GERALDO ROGÉRIO FAUSTINI; LUCAS,NEIDE M. C.
Sementes de M. maritima germinam na temperatura ótima de 25°C com valores máximos na luz, sendo o processo otimizado em temperatura alternada de 25/30°C. Escarificação mecânica promove a germinação. Em sementes nuas, a germinação é promovida e acelerada tanto na luz quanto no escuro. Temperatura de armazenamento e tempo de estocagem alteram a fotossensibilidade das sementes: sementes estocadas à temperatura ambiente por 90 dias perdem o fotoblastismo positivo enquanto que nas estocadas sob baixa temperatura (10°C) este efeito permanece. O teste do tetrazólio demonstra que aos 180 dias de estocagem 46% das sementes permaneceram viáveis. Análises topoquímicas indicam que a principal fonte de reserva destas sementes, localizada nos cotilédones, é proteica.

Autores: Sá,Francisco V. da S.; Nobre,Reginaldo G.; Silva,Luderlândio de A.; Moreira,Rômulo C. L.; Paiva,Emanoela P. de; Oliveira,Fernanda A. de.
ABSTRACT This study aimed to evaluate the tolerance of guava rootstocks under salt stress in the initial development stage. The experiment was conducted in a greenhouse in a randomized block design in a 5 x 3 factorial, consisting of five levels of irrigation water salinity (0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1) and three guava rootstocks (‘Crioula’, ‘Paluma’ and ‘Ogawa’), with four replicates and four plants per replicate. Emergence, growth and phytomass accumulation were evaluated 30 days after sowing. Increased salinity restricts guava emergence, growth and phytomass accumulation, and the most drastic effects occur at levels higher than 1.8 dS m-1. The cultivar ‘Crioula’ is more tolerant to salinity in relation to ‘Paluma’ and ‘Ogawa’, and can be indicated...

Autores: Tosta,Mauro da S.; Almeida,João P. N. de; Góes,Glêidson B. de; Freire,Priscilla de A.; Mendonça,Vander.
ABSTRACT ‘Pitombeira’ does not have organized cultivation, thus requiring information related to the production of seedlings, particularly in relation to chemical fertilizer. In this context, an experiment was conducted in order to define the best dose of nitrogen (N), using urea as N source, to be applied in ‘pitombeira’ seedlings. The experimental design was complete randomized blocks with four replicates and ten plants per plot, testing five N doses (0, 400, 800, 1.600 and 3.200 mg dm-3). Data were submitted to analysis of variance and regression. The non-destructive measurements (number of leaves, stem diameter, shoot length and the ratio between shoot length and stem diameter) were evaluated at 30, 60, 90 and 120 days after transplanting (DAT).

Autores: Reinhardt,Domingo Haroldo; Souza,Ana Patrícia Mascarenhas; Caldas,Ranulfo Correa; Alcântara,José dos Prazeres; Almeida,Alberto Alves de.
The lack of good quality planting material has limited the expansion and contributed to yield reduction of the Brazilian pineapple culture. Alternatives of 'Pérola' pineapple slips management were studied aiming at obtaining superior planting material within a shorter time period and making good use of healthy slips of low vigor, that are commonly discarded by growers. Two experiments were carried out at the Experimental Field of Embrapa Cassava &amp;amp; Fruits, Cruz das Almas, Bahia, Brazil, and another one in a commercial plantation in the region of Itaberaba, BA, using blocks or entirely randomized designs with at least four replications. In the first one, the development of slips of different initial sizes (6 to 20 cm long), when grown on mother...

Autores: Saúco,Víctor Galán; Jahiel,Michel; Modesto,Pedro Hernandez Delgado; Huang,Xu Ming; Mitra,Sisir; Yamanishi,Oswaldo Kiyoshi; Andrade,Renata Aparecida de.
Abstract  The different propagation systems for litchis are reviewed. After examining the main morphological and developmental characteristics of the plant and the description of the structures and materials, including types of substrate required for the propagation of this species, the different methods for its propagation are discussed. Propagation by seeds is only used for breeding or research purposes or for raising rootstock for grafting. Although propagation by cuttings is done in many countries and stooling has been reported as highly successful in India, air layering is the most common commercial way of propagation for this species. Despite that the cambium activity varies from place to place around the stem with only 30% of the cambium being...

 Butia capitata (Mart.) Becc., commonly known as jelly palm, is a palm tree native to the Cerrado biome. It is considered an endangered species owing to intensive extractive exploitation of its fruits, with slow and uneven seminiferous propagation as an aggravating factor. Thereby, there are some bottlenecks related to jelly palm seedling production that needs to be optimized. Light quality and intensity is very important to seedling production, as it controls the metabolism of plants and consequently their growth and development. Thus, the aim of this work is to evaluate the effect of shade nets on the growth and physiological aspects of jelly palm seedlings.

Abstract The jelly palm plant [Butia capitata (Martius) Beccari] is a native palm of the Cerrado biome used for many purposes in northern Minas Gerais State, Brazil. Dormancy is common in palm seeds, resulting in slow and uneven germination that may take years to complete. Modification in the growth pattern, anatomical parameters, physiological and biochemical characteristics of the plant can be verified due to changes in the light spectrum transmitted through colored shade nets used. Therefore, the objective of this study is to evaluate the effect of colored shade nets on the leaf and root anatomy of the jelly palm plant. The experiment was performed in a completely randomized design, with five treatments, ten replicates and eight plants per replicate,...

Provedor de dados: 52
Autores: Scherwinski-Pereira,Jonny Everson; Medeiros,Carlos Alberto Barbosa; Fortes,Gerson Renan de Luces; Pereira,Arione da Silva.
The development of more efficient and productive systems for pre-basic seed potato production would improve the quality of the propagative material used by the potato growers, directly affecting the crop yields. A two-year experiment was carried out to evaluate the potato pre-basic seed production by two types of hydroponic systems (fibrocement tiles and articulated PVC gutters), two cultivars (`Baronesa` and `Eliza`) and two types of propagative material (plants coming from in vitro culture and minitubers). The PVC gutters system was highly efficient. When using minitubers, this system reached multiplication rates up to 74 tubers per plant. Minitubers were more productive than in vitro plants, independent of cultivar and hydroponic system utilized.

In vitro culture of Vriesea gigantea and Vriesea philippocoburgii: two vulnerable bromeliads native to Southern Brazil
Provedor de dados: 52
Autores: Droste,Annette; Silva,Anelise Machado da; Matos,Adriana Vieira; Almeida,Júlia Winck de.
Micropropagation studies were carried out using the seeds for establishing an in vitro culture of Vriesea gigantea and Vriesea philippocoburgii. Germination rate of V. gigantea was higher than of V. philippocoburgii. Plantlets of V. philippocoburgii gave rise to many adventitious shoots when cultivated in Knudson basal medium. In contrast, for V. gigantea, a higher salts-concentration was needed, so that the number of shoots was increased by Murashige and Skoog medium. Addition of activated charcoal and naphthaleneacetic acid in regeneration medium allowed the growth of shoots and the formation of roots, confirming the success of in vitro culture. The differences in expression of the genotypes reinforce the need of more research in order to set up the...

Henequen (Agave fourcroydes Lem.) is a high value plant species both for agricultural and ecological uses. The species is very well known worldwide by the quality of its fiber that is widely used for industrial purposes. This species is propagated at a large scale by asexual methods but current propagation technologies are not satisfying the grower’s demands. A. fourcroydes has been cultivated n vitro but it has shown some recalcitrant behaviour during the multiplication and rooting stages. The combination of 6-benzylamynopurine (BAP) (0.75 mg L-1) and indolebutyric acid (IBA) (1.0 mg L-1) instead of 2,4-dichlorophenoxyacetic acid (2,4-D) significantly improved explant survival and shooting during the establishment of n vitro young shoots.

ABSTRACT The production of Coffea arabica L. clone seedlings through the somatic embryogenesis technique is one of the alternatives of greatest demand for coffee producers. However, clones can face difficulties related to acclimatization carried out under greenhouse conditions, which can increase the production costs. A tested alternative with promising results is inoculation with arbuscular mycorrhizal fungi (AMF) during the seedling acclimatization process. Thus, this study aimed to promote the improvement of the seedling production process through somatic embryogenesis associated with inoculation with AMF. For the production of the clones, seedlings were used in the phase when they presented four pairs of leaves (Clone 1 “Fruiting red Catucaí” and Clone...
