Morphophysiological evaluation of Bauhinia divaricata L. (Fabaceae) plants at different water regimes
Keywords:Florestal species, Dry matter, Seedlings production
The pata-de-vaca (Bauhinia divaricata L.) tree is a species widely distributed in Brazil, it has a high ornamental and economic value. Its leaves are used in renal inflammations, such as diuretic, hypoglycemic, being considered a medicinal plant of popular use. The research was carried out in a greenhouse belonging to the Laboratório de Ecologia Vegetal, at the Centro de Ciências Agrárias (CCA), from Universidade Federal of Paraíba (UFPB). The objective was to evaluate the morphophysiological characteristics of B. divaricata plants at different water regimes. The experimental design was completely randomized with five water treatments 1 (100% control), 2 (80%), 3 (60%), 4 (40%) and 5 (20%) of the container capacity. The height, number of leaves and stem diameter were evaluated weekly. At the end of the experiment the plants had their organs separated and taken to the greenhouse to obtain the dry matter of the leaves, stem, roots and total dry matter, and also, biomass allocation in the leaves, stem and roots. Plant height did not differ statistically between the treatments. The number of leaves, diameter, leaf, stem and root allocation and root and shoot dry matter were higher under water availability (100% of container capacity). For the production of B. divaricata L. seedlings water regime should be 100% and 80% of the container capacity, but the seedlings grow satisfactorily.
