1. Evidences of self planting propagules of Rhizophora mangle L.
Abstract: The authors of the 19th century had demonstrated the viviparity of the species Rhizophora mangle L. with the formation of propagules in the form of spears devoid a radicle, adapted self-planting in the soil of the mangrove or to leave floating in vertical during the high tide. With low tide the propagules self-planting or remain prostrate on the so

2. Ex situ initial seedling development of Hymenaea courbaril L. (Fabaceae): a crucial phase to preserve the species
RESUMO Hymenaea courbaril L. é uma importante espécie Neotropical, que aparece com baixa densidade populacional, restrita a fragmentos de florestas semidecíduas, com baixa mortalidade e baixo recrutamento. Assim, algumas questões orientaram os objetivos deste trabalho, incluindo a capacidade de sementes armazenadas para formar mudas normais. Sementes col

3. Green propolis ethanolic extract in bean plant protection against bacterial diseases
RESUMO: Este trabalho teve como objetivo avaliar o extrato etanólico de própolis verde (EEP) na proteção de plantas de feijoeiro contra as duas principais bacterioses da cultura, crestamento bacteriano (Xanthomonas axonopodis pv. phaseoli) e fogo selvagem (Pseudomonas syringae pv. tabaci). Foram realizados experimentos sobre atividade antimicrobiana ind

4. Efficient and new method for Tectona grandis in vitro regeneration
Abstract The aim of this study was to develop a shoot regeneration protocol for Tectona grandis by examining the effects of pretreatments, regeneration culture medium, adventitious rooting, and acclimatization. The best organogenic potential was achieved when hypocotyls and cotyledonary segments from seedlings germinated on a medium containing TDZ, were cult

5. Evaluation of limonoid production in suspension cell culture of Citrus sinensis
ABSTRACTThe use of cell and plant tissue culture techniques to produce economically important active metabolites has been growing. Among these substances are total limonoid aglycones, which are produced by "pera" orange (Citrus sinensis (L.) Osbeck, Rutaceae) and have received considerable attention because of their anticancer actions. The main objective of

6. Supression of seed borne Cladosporium herbarum on common bean seed by Trichoderma harzianum and promotion of seedling development
Trichoderma harzianum isolates have been broadly used for biocontrol of plant diseases caused by fungi. Cladosporium herbarum is a common saprophyte and seed borne fungus, which is easy to manipulate under controlled conditions. It was chosen as a model to test the effectivity of seed treatments with T. harzianum. Common bean seeds (cv. Pérola) contaminated

7. Genetic potential of common bean parents for plant architecture improvement
In common bean (Phaseolus vulgaris L.) breeding, plant selection that associate erect plant architecture, high yield, and grains with good commercial acceptance has been the choice of breeders. Thus, this study aimed to evaluate potential parents, to obtain promising segregating populations that associate high yield, erect plant architecture and carioca grai

8. Emergência, crescimento inicial de plântulas e enxertia hipocotiledonar por garfagem no topo em fenda cheia com miniestacas apicais para diferentes passifloráceas
Passion fruit is composed of about 630 species, which include economically three species: Passiflora edulis Sims f. flavicarpa, Passiflora alata and Passiflora edulis. Considering that their culture is prominent in South America with about 90% of world production and that Brazil is the worlds largest producer of this culture the objective of this study was t

9. In Vitro Regeneration of Several Accessions of Solanum Topiro Humb & Bonpl. and S. Sessiliflorum Dun. (Cúbio)
Leaf and hypocotyl explants of twelve accessions of Salanum tropiro and one accession of S. sessiliflorum ("cúbio") were tested for their morphogenetic response by culturing them in Murashige & Skoog (1962) medium supplemented with combinations of naphthaleneacetic acid (NAA) and benzylaminopurine (BA). Hypocotyls were the best explants for shoot regenerati

10. Potencial hídrico induzido por polietilenoglicol-6000 no vigor de sementes de algodoeiro.
A hidratação é o fator externo mais importante na germinação de sementes. Para simular as condições complexas do solo, soluções com diferentes potenciais hídricos têm sido usadas para umedecer os substratos de germinação. O objetivo deste trabalho foi avaliar os efeitos do estresse hídrico sobre o vigor de sementes de algodão (Gossypium hirsut

11. Chill-induced changes in fatty acid composition of tonoplast vesicles from hypocotyls of Vigna unguiculata (L.) Walp.
O presente trabalho analisa as mudanças na composição de ácidos graxos de vesículas de tonoplato de hipocótilos de Vigna unguiculata (L.) Walp induzida por estresse causado por baixas temperaturas. Plântulas em condição controle desenvolveram-se por 7 dias à temperatura de 25°C e as plântulas tratadas foram submetidas a 10 ou 4°C por 4 dias, 3 d

12. Effects of a methanolic fraction of soybean seeds on the transcriptional activity of peroxisome proliferator-activated receptors (PPAR)
Since the anti-inflammatory, antidiabetic and hypolipidemic effects of soy isoflavones may be mediated by activation of peroxisome proliferator-activated receptors (PPAR), the present study investigated whether the methanolic fractions obtained from soybean seeds (E1) and soybean seed coats with hypocotyls (E2) could influence PPARα, PPARγ and PPARβ/δ tr
