Ceratocystis fimbriata Ellis & Halsted recently was recorded causing seed and seedling blight on Carapa guianensis Aubl. (andiroba), a tree species native to the Amazon Rainforest and prized for its valuable timber and medicinal seed oil. C. fimbriata more commonly causes wilt type diseases in woody hosts, especially on non-native host trees. However, on andiroba the disease occurs on seedlings and seeds, affecting the species regeneration. We studied 73 isolates of C. fimbriata on andiroba from three regions of the Amazon Basin to see if they represented natural or introduced populations. Analysis of ITS rDNA sequences and phylogenetic analysis of mating type genes revealed new haplotypes of C. fimbriata from the Latin American Clade that were closely...

Com o objetivo de se estudar as exigencias nutricionais no desenvolvimento inicial de mudas de Peltophorum dubium (Spreng.) Taub., foi realizado um experimento em casa de vegetacao. Usou-se como substrato um Latossolo Vermelho-Amarelo com baixa disponibilidade de nutrientes, utilizando-se 10 tratamentos, sob a tecnica do elemento faltante. Foram aplicados um tratamento completo (com N, P, K, Ca, Mg, S, B e Zn), outros com omissao de um nutriente por vez (-N, -P, -K, -Ca, -Mg, -S, -B, e -Zn) e uma testemunha (solo natural). Foram avaliadas as seguintes caracteristicas: altura, diametro, peso de materia seca da parte aerea e das raizes, e teor de nutrientes na materia seca da parte aerea. Concluiu-se que as plantas do angico-amarelo apresentam elevada...

Abstract The lack of an efficient method of propagation in some cultivars makes it difficult to expand the blueberry culture. In Brazil, we still do not produce seedlings with needed quality and quantity to improve the sector. The cloning of the selected material through mini propagation and micro propagation is an alternative to increase the multiplication and rooting capacity of the blueberries. Allied to this, the use of cultivation system without soil for the development of cloned material facilitates the seedlings production. In addition, we can keep matrices in small spaces with the use of mini-gardens and clonal micro-gardens controlling climatic and nutritional factors. In the Laboratory of Fruit Plants Propagation, of the Phytotechnology...

Abstract In Brazil, there is a growing interest in the crop of the olive tree, especially in those regions considered suitable for cultivation, where low temperatures occur between 8ºC and 10ºC in the period before flowering. The areas with these characteristics are located mainly in the South and Southeast regions of the country, characterized by a temperate climate in function of altitude, with the occurrence of natural vernalization. The propagation is an integral part of the production chain and the first step towards the implantation of the olive tree crop or renovation of the existing orchards. Obtaining quality seedlings, besides guaranteeing uniformity and reliable varietal origin, is a factor that influences the whole life of the orchard,...

The development and optimization of efficient transformation protocols is essential in new citrus breeding programs, not only for rootstock, but also for scion improvement. Transgenic 'Hamlin' sweet orange (Citrus sinensis (L.) Osbeck) plants were obtained by Agrobacterium tumefaciens-mediated transformation of epicotyl segments collected from seedlings germinated in vitro. Factors influencing genetic transformation efficiency were evaluated including seedling incubation conditions, time of inoculation with Agrobacterium and co-culture conditions. Epicotyl segments were adequate explants for transformation, regenerating plants by direct organogenesis. Higher percentage of transformation was obtained with explants collected from seedlings germinated in...

Root anatomical responses to water deficit are diverse and regulation of water uptake strongly depends on plant anatomy. The ancestors of common bean (Phaseolus vulgaris L.) cultivars are the wild common beans. Because wild beans adapt and survive well in theon atural environment, it is hypothesized that wild common bean roots are less affected than those of domesticated beans at low substrate water potential (ψW). A wild common bean accession from Chihuahua Mexico and cv. Bayomex were studied. Seedlings with a mean root length between 3 and 4 cm were maintained for 24 h in vermiculite at ψW of -0.03 (well hydrated), -0.65, -1.48 and -2.35 MPa (partially dry). Ten anatomical characteristics of differentiation and cell division in root...

Arbuscular mycorrhizal fungi associated with the rhizosphere of seedlings and mature trees of Swietenia macrophylla (Magnoliophyta: Meliaceae) in Los Tuxtlas, Veracruz, Mexico

BACKGROUND: Big-leaf mahogany (Swietenia macrophylla King) is the woody species with the highest economic value in Latin America. Currently, it is subject to intensive exploitation, diminishing its natural populations. Due to this decline, the species is a preferred species for reforestation and establishment of commercial tropical plantations. Mycorrhizal symbiosis is a biotic factor scarcely studied in the ecology of this species. Therefore, the objective of this research was to identify the diversity of arbuscular mycorrhizal fungi (AMF) species associated with the rhizosphere of seedlings and mature trees of big-leaf mahogany growing in its natural habitat, a tropical rain forest in Los Tuxtlas, Veracruz, Mexico. Soil samples from a 20-cm depth were...

ABSTRACT The capacity to solubilize phosphate and to produce indole compounds Indole Acetic Acid type, was evaluated in 15 strains isolated from castor bean lignocellulosic residues (Ricinus communis). To determine the solubilizing activity of phosphates a qualitative test by using Pikovskaya culture medium was employed and for the evaluation of the production of indole compounds (IAA) a Salkowsky colorimetric analysis technique was applied. Among the microorganisms tested, the Bacillus pumilus GIBI 206 demonstrated capacity to solubilize phosphates and Bacillus subtilis GIBI 200 showed of capacity to solubilize phosphates and to produce Indoleacetic Acid (IAA). To determine the effect of the Bacillus subtilis strain on germination and growth promotion,...

Direct sowing has been proposed as an alternative to planting seedlings because of its low cost. However, there are still few works with direct seeding that aim to select species that best respond to the technique. Therefore, we carried out a direct sowing study with native tree species of the Semideciduous Seasonal Forest in Southern Brazil (Serra do Sudeste, State of Rio Grande do Sul).

Com o objetivo de avaliar diferentes fases de desenvolvimento de mudas de aspargo visando a determinar a idade ideal de transplante, instalou-se, no periodo de julho de 1987 a julho de 1988, um experimento no Campo Experimental de Gorutuba, Porteirinha-MG, utilizando-se a cultivar Argenteuil Precoce. O delineamento experimental foi inteiramente casualizado, avaliando-se mudas com onze distintas fases de desenvolvimento (60;90;120;150;180;210;240;270;300;330 e 360 dias apos a semeadura), em tres repeticoes. Pelos resultados obtidos, recomenda-se o transplante de mudas com 180 dias, como a idade ideal de transplante nas condicoes da regiao Norte de Minas Gerais, quando as mesmas atingiram 103,65 cm de altura, 6,91 hastes verdes, 74,42 raizes carnosas, 78,17...
