MORFOGÊNESE E ESTRUTURA DO CAPIM Cynodon spp. EM MONOCULTURA TANTO A PLENO SOL COMO EM SOMBREAMENTO ARTIFICIAL

Abstract: Objetivou-se avaliar as características morfogênicas e estruturais do capim Cynodon spp. em diferentes idades de rebrota, em ambientes a pleno sol e sombreamento artificial sob pastejo de ovinos. O experimento foi realizado na zona rural de Geminiano (PI), no período de agosto de 2017 a julho de 2018. Para a densidade de perfilhamento, adotou-se o delineamento inteiramente casualizado em esquema fatorial 2x2, com dois tratamentos (pleno sol e sombreamento artificial) e duas condições de pastejo (pré e pós-past… Show more

“…The carbon allocation in shaded plants is considered an acclimation mechanism, acting on the increase and recovery of leaf area and stem elongation (Torres et al, 2019), to enhance light uptake (Lemaire, 2001;Anjos & Chaves, 2021), i.e., the plant changes its morphological behavior to compensate for light deficiency.…”

“…Another change in the morphological behavior of plants under shading is the increase in leaf blade length at the expense of the reduction in light intensity (Torres et al, 2019). This event is considered a compensatory effect in the photosynthetic apparatus, because to the low availability of radiation, the plant needs more leaf area to capture light, prioritizing to investing its resources in the formation of leaf tissues.…”
