Stem Population and Tissue Replacement of Urochloa in Different Phenological Stages.

Abstract

The objective of the present investigation was to evaluate the Urochloa Insurgent, Piata and Signal grasses by varying the phenology in the attributes: stem population dynamics, tissue replacement, leaf:stem relation and weight per stem. The data were analyzed using a completely randomized block de sign with arrangement in divided plots and four replications, the procedure used was PROC GLM from SAS. The Signal grass presented higher stem density with an average of 450 m¿2 stems, while the meadow with Insurgent grass registered the lowest stem density throughout the investigation, with an average of 320 m¿2 stems; furthermore, in this treatment, the stem density tended to increase slowly over time (P = 0.05).
