Abstract: Leaf appearance rate and phyllochron are related variables which play a central role in forage production. Phyllochron is the time interval between the appearance of successive leaves and varies according to a number of environmental factors, among which temperature is the most important. The experiment was conducted in natural pasture with the aim of testing phyllochron variation under different seasons, herbage allowances, and topographic positions. Marked tillers were used to define the phyllochron, establi… Show more

“…Morphogenesis studies on native grasses of the Pampa biome have already been conducted (Cruz & Boldrini, 1998;Trindade & Rocha, 2001Eggers et al, 2004) and in some of them, the effect of N fertilization on the morphogenetic traits of some species was evaluated (Denardin, 2001;Bandinelli et al, 2003;Nabinger et al, 2003;Santos, 2004;Quadros & Bandinelli, 2005;Townsend, 2008). In these reports, it was verified that leaf elongation rate is positively related with N.…”

“…Data collection began on January 6th, 2009, when all the grasses were cut. The thermal sum required for the emergence of 2.2 leaves in P. notatum (Eggers et al, 2004) which is equivalent to 350 degree days was used as a criterion for the interval between cuts for prostrate growth habit species (A. affinis, P. notatum). For caespitose plants (A. lateralis, A. laevis, E. angustifolius, P. plicatulum, P. montevidense and S. pellitum) it was considered twice this value, i.e., the thermal sum equivalent to 700 degree days.…”

“…As folhas completamente expandidas apresentaram maior peso (P<0,05) quando comparadas às emergentes. Resultados semelhantes foram observados por Pontes et al (2004) e Eggers et al (2004). Dessa forma, o peso das folhas completamente expandidas foi de 1,23 ± 0,23 mg de MS/cm (CV= 21,32%) e o das folhas emergentes, de 1,04 ± 0,24 mg de MS/cm (CV= 22,94%).…”

“…O experimento foi instalado em um Argissolo Vermelho Distrófico Típico (EMBRAPA, 1999), sendo o terreno levemente ondulado, sem limitações para cultivos anuais. Para determinação da fertilidade do solo, foram retiradas amostras na profundidade de 0 -10 cm.…”

“…Para promover práticas de manejo sustentáveis, é necessário o entendimento dos processos de crescimento vegetal por meio de variáveis morfogênicas. O estudo dessas variáveis é ainda restrito a poucas espécies que compõem o Bioma Campos Sulinos, podendo ser citados trabalhos com Andropogon lateralis (BANDINELLI et al, 2003;MACHADO, 2010); Piptochaetium montevidense (MACHADO, 2010); Briza subaristata (DENARDIN, 2001), Paspalum notatum (MACHADO, 2010); Coelorhachis selloana (EGGERS et al, 2004); Paspalum urvillei (QUADROS & BANDINELLI, 2005), Sorghastrum pellitum, Paspalum plicatulum, Aristida laevis, Axonopus affi nis e Saccharum angustifolius (MACHADO, 2010). Todas as avaliações, exceto as de BANDINELLI et al (2003) Os dados meteorológicos se aproximaram às médias históricas com uma variação de 7,4, 5,0 e 11,3% para menos, para temperatura, umidade e precipitação pluviométrica, respectivamente.…”
