A distinction between the actions of abscisic acid, gibberellic acid and cytokinins in light-sensitive lettuce seed.
Using isolated lettuce seed embryos it can be shown that the inhibitory effect of abscisic acid upon germination is reversed solely by cytokinin. In the intact seed, however, gibberellic acid is also required for this reversal to be manifested in germination.
