EFEITO DA TEMPERATURA E DA LUZ NA GERMINAÇÃO DE SEMENTES DE ALFAVACA (Ocimum basilicum L.)

This study evaluated the effect of different temperatures and light conditions on Ocimum basilicum L. seed germination. The treatments were the temperatures of 20ºC, 25ºC and 30ºC and two different light expositions (constant dark and 8h of light plus 16h of dark). The tested variables were first count germination and germination percentage. The treatments consisted of 200 seeds, with four replications of 50 seeds each, sown on filter of paper for 14 days on germination chamber. The completely randomized design was used and the averages compared by Tukey test at 5% probability. The specie of Ocimum basilicum is positive photoblastic and temperature of 30ºC was the best condition for seed germination.
