Phenotypic Reversion of Flacca, a Wilty Mutant of Tomato, by Abscisic Acid

Dorot Imber 1 and Moshe Tal 1

1 Negev Institute for Arid Zone Research, P.O. Box 1025, Beer-Sheva, Israel

The tomato mutant flacca wilts rapidly under water deficit because its stomata resist closure. Application of abscisic acid to intact mutant plants changes their morphology toward the phenotype of the control normal variety, Rheinlands Ruhm. The treated mutant plants do not show wilting symptoms, and the resistance to closure of their stomata decreases with hormone treatment.
