GERMINACIÓN Y EMERGENCIA DE Megathyrsus maximus VAR.maximus

ABSTRACT This work aimed to study the germination of Megathyrsus maximus seeds when exposed to high temperatures, as well as to evaluate the effects of different seed planting depths and sugarcane crop residue amounts on weed emergence. In the laboratory, germination and biomass of seeds with and without glumes were determined when exposed to 0, 40, 60, 80 and 100 oC, for five minutes. Two experiments were performed in the greenhouse to assess the emergence rate in relation to different weed seed planting depths (0, 0.5, 1, 2, 3, 4, 5, 7 and 8 cm) on the one hand, and in relation to different ...
