Plant establishment depends on the ability of seeds and seedlings to adapt to adverse environmental conditions. Thus, the objective of this study was to evaluate the influence of the increase in air temperature (with variations throughout the day) the emergence and initial growth of sorghum cultivars (Sorghum bicolor L. Moench). The experiment was conducted in growth chambers in a 7x3 factorial scheme with a completely randomized design using seven sorghum cultivars (AGRI 002E, BRS 506, BRS 716, SF15, IAC Santa Elisa, BRS Ponta Negra and, Volumax) and three temperatures: T1 (20.0-26.0-33.0°C); T2 (24.8-30.8-37.8°C); T3 (27.8-33.8- 40.8°C), with four replications of ten seeds. The following aspects were evaluated: emergence percentage, emergence speed index, average emergence speed, average emergence time, length, and fresh and dry mass of seedlings. |
