Germinatiob and growth (inhibitors in the fruits of pittosporum tobira ait, during ripening.
Abstract
Germination and growth inhibitor (s) in different fractions of ripening fruits of pittosporum tobira was studied . both unripe and ripe fruits contained germination and growth inhibiting substance (s) in the water-soluble, acidic and neutral fractions as compared to unripe fruits, germination and growth inhibitor (s) increased 2-3 folds in the ripe fruits . it is suggested that the increase in acidic inhibitor (s) during ripening may reflect the increase in the level of endogenous ABA-like substances.
