1. Mini-cutting rooting and plantlet growth in Erythrina crista-galli L.
ABSTRACT In this study, we evaluated the adventitious rooting competence of mini-cuttings and plantlet growth of two clones of swamp cork (Erythrina crista-galli L.). Experiments were carried out in a factorial of two clones to study the need of application of indolebutyric acid (IBA), substrate composition for mini-cutting rooting and plantlet growth, and r

2. Methyl jasmonate modulation reduces photosynthesis and induces synthesis of phenolic compounds in sweet potatoes subjected to drought
ABSTRACT Sweet potato [Ipomoea batatas (L.) Lam.] has wide adaptability to different climatic conditions. However, its yield can be affected by prolonged periods of drought. Application of exogenous jasmonates can modulate several physiological and biochemical processes, improving plant tolerance to abiotic stress. This study sought to evaluate the role of e

3. Rizogênese in vitro em brotações de Luehea divaricata Mart. & Zucc.
Resumo Luehea divaricata, conhecida popularmente como açoita-cavalo, é uma espécie florestal nativa da Mata Atlântica muito utilizada para a recuperação de áreas degradadas. Sua madeira pode ser empregada para as mais diversas finalidades, o que contribuiu para a redução de suas populações naturais e ocasionou dificuldades na obtenção de semente

4. Anatomical and histochemical comparison of the primary and adventitious roots of Attalea microcarpa (Arecaceae) at the initial growth stage
RESUMO Este estudo descreve a estrutura anatômica de raízes originárias do apocole de Attalea microcarpa, em comparação à raiz primária por meio de técnicas usuais para microscopia óptica. As raízes adventícias são diferenciadas no apocole, associadas a feixes vasculares, e podem se manter como uma estrutura única ou se ramificar. Possuem a estr

5. 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

6. Can indolebutyric and fulvic acids induce adventitious rhizogenesis on mini-cuttings from Brazilian native tibouchinas?
Resumo O uso de espécies nativas brasileiras para fins ornamentais é uma alternativa promissora para a floricultura local. Buscando contribuir com novas informações neste contexto, objetivou-se avaliar o desempenho de enraizamento de miniestacas de três espécies de Tibouchina (T. aff. fothergillae, T. heteromalla e T. moricandiana var. vinacea) com o u

7. Physiological Responses to Hypoxia and Manganese in Eucalyptus Clones with Differential Tolerance to Vale do Rio Doce Shoot Dieback
ABSTRACT: Vale do Rio Doce shoot dieback (VRDSD) is an anomaly whose cause seems to be associated with hypoxic conditions and their consequences (excess Mn and Fe) triggered by elevation of the water table in areas with poor drainage. Different plants have distinct survival strategies under this form of stress. The objective of this study was to understand t

8. Mini-incubators improve the adventitious rooting performance of Corymbia and Eucalyptus microcuttings according to the environment in which they are conditioned
ABSTRACT We addressed a major challenge in the in vitro clonal propagation of Corymbia citriodora, Eucalyptus urophylla and E. benthamii by using an ex vitro adventitious rooting strategy in a mini-incubator. Mini-incubators were placed in four environments for rooting. A shade house with no fogging system and a greenhouse with no ventilation but with a fogg

9. SUNFLOWER EMERGENCE AND INITIAL GROWTH IN SOIL WITH WATER EXCESS
ABSTRACT: Sunflower crops are grown in different regions worldwide. However, the stress caused by water excess in the soil impairs this crop growth and yield. The aim of the present study was to determine the response of sunflower plants to long periods of water excess during initial development stages. Water excess treatments were applied at the initial dev

10. Morpho-anatomical study of Stevia rebaudiana roots grown in vitro and in vivo
ABSTRACT Stevia rebaudiana (Bertoni) Bertoni, Asteraceae, is used as a food additive because its leaves are a source of steviol glycosides. There are examples of tissue culture based on micropropagation and phytochemical production of S. rebaudiana leaves but there are few studies on adventitious root culture of S. rebaudiana. More than 90% of the plants use

11. Anticonvulsant mechanism of saponins fraction from adventitious roots of Ficus religiosa: possible modulation of GABAergic, calcium and sodium channel functions
ABSTRACT In our previous studies, quantified saponins-rich fraction from adventitious root extract of Ficus religiosa L., Moraceae, showed anticonvulsant effect in acute, as well as chronic mice models of epilepsy. The present study was designed to reveal putative anticonvulsant mechanism of quantified saponins-rich fraction using target specific animal mode

12. Influence of Benzyladenine and Thidiazuron on Shoot Regeneration from Leaf and Shoot tip Explants of Sedum sarmentosum Bunge
Effects of N6-benzyladenine (BA) or thidiazuron (TDZ) on adventitious shoot regeneration and axillary shoot multiplication of Sedum sarmentosum was investigated. Leaf and shoot tip explants obtained from in vitro-grown shoots of S. sarmentosum were cultured on Murashige and Skoog (MS) medium supplemented with 0, 2.0, 4.0 or 8.0 µM BA or TDZ. Of the two cyto
