Abstract: RESUMO -A proporção de tecidos, o grau de correlação linear desta característica com a digestibilidade in vitro da matéria seca (DIVMS) e sua composição química foram determinadas em seções transversais das frações botânicas, lâmina e bainha foliares e colmo, amostrados no topo e na base de perfilhos de capim-elefante (Pennisetum purpureum, cv. Mott), capim-setária (Setaria anceps, cv. kazungula) e capim-jaraguá (Hyparrhenia rufa). O capim-jaraguá, com maior proporção de bainha parenquimática dos feixes (BPF) … Show more

“…Opposite correlation was found between these tissues and the percentage of ADF. These results were similar to found for tropical grasses, where a positive correlation between epidermis and CP, and a negative correlation between ADF and epidermis and ADF and lignifi ed vascular tissue were observed (QUEIROZ et al, 2000). The nutritive value of forage plants is the result of many attributes and therefore the effect of management practices can be better analyzed when it is considered the set of variables.…”

“…The tissues lowest digested correlate negatively with CP and in vitro dry matter digestibility (IVDMD) (PACIULLO, 2002). In addition, neutral detergent insoluble fi ber (NDF) and ADF has been correlated with leaf anatomy (QUEIROZ et al, 2000).…”

“…O efeito da estação sobre o percentual de FVT do capim-braquiária foi inconsistente (P>0,01), mas ocorreram (Queiroz et al, 2000). Os resultados da análise químico-bromatológica (Tabela 2) e da reação positiva com a safranina O (Figuras 1a, 1b, 1c e 1d) comprovam essa afirmativa, reforçada pelas correlações negativas (r = -0,85 e r = -0,90, respectivamente), entre esses tecidos e a digestibilidade (Tabela 3), evidenciando o caráter de barreira desses tecidos no processo de digestão.…”

“…Correlações negativas entre DIVMS e os componentes da parede celular foram reportadas por e Queiroz et al (2000), porém com valores inferiores aos encontrados nesse trabalho. As altas correlações encontradas nesse trabalho decorreram das características extremamente marcantes das quatro espécies estudadas.…”
