Abscisic acid and assimilate partitioning to developing seeds. III. Does abscisic acid influence sugar relaease from attached empty seed coats in an ABA-deficient Pisum sativum mutant?

Influence of abscisic acid on the release of sucrose from surgically modified Pisum sativum ovules was studied with the use of a wilty pea mutant and variations in the amount of available assimilates. Phloem import was unaffected by applied ABA, independent of the endogenous ABA level and source-lim...

Description
Summary:Influence of abscisic acid on the release of sucrose from surgically modified Pisum sativum ovules was studied with the use of a wilty pea mutant and variations in the amount of available assimilates. Phloem import was unaffected by applied ABA, independent of the endogenous ABA level and source-limited conditions.
