| Abstract: | Endogenous levels of ABA in photoblastic lettuce seeds weredecreased both by red-light irradiation and exogenously appliedgibberellin. Since red light increases endogenous levels ofGA1 and exogenously applied ABA inhibits both red-light- andgibberellin-induced germination, a decrease in ABA may be importantfor germination.
