Estudaram-se características morfogênicas e estruturais de azevém (Lolium multiflorum Lam.) sob intensidades de pastejo. O delineamento experimental foi inteiramente casualizado, com quatro repetições (transectas) e três tratamentos constituídos por intensidades de pastejo: “Alta”, “Média”, “Baixa”, correspondentes ao desaparecimento de 61,0; 43,3 e 21,1% do valor da massa de forragem inicial, respectivamente. O pastejo foi intermitente, com borregas, e o intervalo entre pastejos correspondeu à soma térmica de 313 graus-dia. As intensidades de pastejo afetaram a morfogênese e estrutura de azevém apenas no primeiro período de avaliação, quando o azevém na intensidade “Média” apresentou as menores taxas de aparecimento e elongação foliar e os maiores valores...

The experiment evaluated the morphogenesis and structure of Tifton 85 (Cynodon spp.) cultivated in subtropical climate and fertilized with nitrogen (N). The experiment was a completely randomized design with four levels of N (Zero; 75; 150 or 225 kg ha-1) in nine replicates per area. The experimental animals were Suffolk female lambs. The grazing method was continuous to maintain the sward height at 15 cm ± 10%. The stem expansion increased by 0.000027 cm degree-days-1 to each kg N applied (linear model). According to nonlinear model, the highest stem expansion (0.0226 cm degree-days-1) was observed with the use 220.1 kg ha-1 N. The leaf lifespan fitted a linear regression model, with increase of 50 degree-days leaf -1, comparing the levels zero and 225 kg...

Structural and morphogenical characteristics of black oats and Italian ryegrass on pasture submitted to two grazing intensities
Provedor de dados: 96

Morphogenical and structural characteristics of black oats (Avena strigosa Schreb.) and Italian ryegrass (Lolium multiflorum Lam.) on pastures managed under two grazing intensities were quantified by using marked tiller technique. The expected intensities of disappearance of forage mass initial value were 35% (low) and 65% (high). Experimental animals were sheep and interval among grazing was determined through 300 degree-day thermal sum. The experimental design was completely randomized with two grazing intensities and two replicates. Leaf blades of oats and ryegrass were removed at an average proportion of 57.5% of their initial length for both grazing intensities. Among the morphogenical characteristics of oats, only elongation rate of defoliate leaf...
