Última EFFECTS OF ENVIRONMENTAL FACTORS ON SEED GERMINATION AND EMERGENCE OF GLYPHOSATE RESISTANT AND SUSCEPTIBLE SOURGRASS Planta Daninha MARTINS,J.F.; BARROSO,A.A.M.; ALVES,P.L.C.A.. ABSTRACT Sourgrass is one of the most problematic weeds of Brazil. It is an aggressive species in the allocation of resources from the environment and reported to be glyphosate resistant in several states of the country. This work has aimed to verify environmental effects on seed germination and seedling emergence of sourgrass. Laboratory and field trials were conducted to determine the effects of temperature, light, photoperiod, water availability and depth of burial in germination and emergence of seeds. The maximum germination was greater than 80% for seed originated from resistant plants between 15 and 30 oC. For the susceptible ones, the maximum germination occurred only at 30 oC. Germination occurred for both biotypes independent of the presence of... Tipo: Info:eu-repo/semantics/article Palavras-chave: Digitaria insularis; Water availability; Photoperiod; Seeds; Temperature.
