Abstract

Abscisic acid (ABA) caused an increase in total-sugar and a 3-fold increase in reducing-sugar content in the roots of intact bean seedlings. The level of reducing sugars was also increased in the stem but total sugar levels remained unaffected by ABA. ABA also increased reducing-sugar content of the root in seedlings with cotyledons removed but in this case the reducing- and total-sugar contents of the leaf were reduced. However, ABA did not affect reducing- and total-sugar levels in excised bean root systems. The observed increase in sugar content of the root of intact bean seedlings appears to be the consequence of an ABA-induced stimulation of sugar transport from the shoot to the root. It is proposed that a relationship may exist between the effect of ABA on sugar transport and its effect on ion transport in excised root systems and in intact seedlings.
