Protein dilution curves in genotypes of Brachiaria humidicola (Rendle) Schweick
Main Article Content
Abstract
higher protein dilution, respectively. The protein content was correlated negatively with the DMP and the height (P < 0.001). The means of the parameters of the curves showed a rate of synthesis of dry matter of 0.0312 t d-1 and of protein of 0.2083 t d-1. The discriminating analysis applied to the curves evidenced significant differences (P < 0.05) between the genotypes. It was concluded that the genotypes of B. humidicola and the age cut are a source of variation in the performance of the protein dilution curves, and that these curves can be used as tool to select the genotypes with lowest protein dilution rate as the plant grows.
Key words: dry matter production, height, protein, dynamic model, discriminating analysis, protein dilution curves.
