Luz, Processo germinativo, Trifolium resupinatumAbstract
O objetivo deste estudo foi avaliar a influência da luz ultravioleta na germinação de sementes de Trifolium resupinatum L (trevo Persa). As sementes foram submetidas a diferentes tempos (doses) de exposição à luz UV-B e UV-C e intensidade de radiação 2.5 W m-2. Em seguida, foram semeadas em caixas gerbox com papel germitest e armazenadas em câmara Biochemical Oxygen Demand, a 20ºC. Foram realizados os testes de germinação, índice de velocidade de germinação, comprimento e massa seca de plântulas. Não foram observadas diferenças significativas entre os tratamentos com luz UV-B. No entanto, as sementes expostas a 8 horas à luz UV-C apresentaram redução no índice de velocidade de germinação quando comparadas ao controle (de 92,5 para 88,7). Além disso, o comprimento das plântulas apresentou aumento médio de 1,3 cm em relação ao controle. Nas condições deste estudo, concluiu-se que as sementes de trevo Persa apresentam relativa tolerância à radiação UV-B, embora apresentem alguma sensibilidade à radiação UV-C. A peletização das sementes associada ao tegumento atuou como um bloqueio físico, impedindo a passagem da luz ultravioleta. Os resultados contribuem para a compreensão de como o trevo Persa responde à exposição à radiação UV.
