Caracterização morfológica e produção de matéria seca de diferentes leguminosas nativas.

Abstract

Brazil is extremely rich in natural resources, being the cradle of plant species of forage interest. As national animal production occurs almost entirely in pastoral systems, which is the cheapest form of animal feed, it is necessary to study forage species adapted to different edaphoclimatic conditions, as well as persistent ones to contribute to the sustainability of production systems animals to pasture. Desmanthus spp and Stylosanthes spp are legumes that occur spontaneously in Northeastern Brazil, with desirable characteristics for cultivation and feeding of ruminants. The objective was to evaluate the morphological and productive characteristics of accessions of Stylosanthes spp and Desmanthus spp from different locations, which make up the Active Germplasm Bank (BAG) of the Federal Rural University of Pernambuco (UFRPE). The plants were cultivated in a greenhouse at the Department of Animal Science and transferred to the BAG / UFRPE, located in the Experimental Station of Sugarcane do Carpina, North wood zone of the state at latitude 7º, 51 '04' 'S, longitude 35º, 14 '27' 'The altitude of 180m in 2017. Variance was observed in all morphological and productive characteristics studied, both for Desmanthus genotypes and for Stylosanthes genotypes, showing the variability between materials and the possibility of being selected superior to the future.
