Caracterização Morfológica de Cultivares de Panicum cultivados no Ecótono Cerrado-Amazônia.

Abstract

Grasses of the genus Panicum are widely recognized for their productivity, nutritional quality and soil fertility requirement, requiring medium to high fertility soils for good forage production. The study of the morphology of forage species has generated important information and knowledge about its development. The objective of this study was to evaluate the characteristics of the external morphology of Panicum grasses present in the agronomic field of the School of Veterinary Medicine and Animal Science (EMVZ / UFT). The characterization of the plants was carried out during 2016 and early 2017 at different times of the year through photographic records of its organs: leaves, roots inflorescence and stem. The images were recorded from cultivars of Colonião, Mombaça, Massai, Aruana, Aries and Atlas. After the records, the classification of the morphological characteristics was carried out with the aid of the literature and a database of the cultivars of Panicum. We concluded that there are similarity among the cultivars, presenting as general morphological characteristics, perennial plants of cespitoso habit, their stems are erect, leaves lanceoladas, the inflorescences are an open panicle, its cariopses are small and elliptic.
