Abstract
Application of the leaf plastochron index (LPI) allowed the consistent description of root regenerative capacity from tomato leaf cuttings. GA3 inhibited root regeneration regardless of LPI. This inhibition was alleviated by IAA or IBA if applied prior to, during, or after GA3 treatment. However, ABA reversed rooting inhibition only if applied prior to or during GA3 treatment. The GA3 effect on rooting was correlated with an inhibition of localized starch accumulation within the basal petiole regions prior to and during initiation of the root primordia. GA3 had no significant effect on the amount or intercellular distribution of amylolytic activity within the petiole tissues during this period. On the basis of the present study, we hypothesize that the mode of GA3 action involves a localized inhibition of starch synthesis rather than increased starch hydrolysis which may, in turn, lead to inhibition of root regeneration in tomato leaf cuttings.
