RELATIONSHIP BETWEEN ETHYLENE EVOLUTION AND LEAF ABSCISSION

Abstract

The abscission of petiole explants of Phaseolus vulgaris can be correlated with the presence of endogenously produced ethylene. In all cases active promoters of abscission induced the evolution of ethylene prior to observable tissue separation. Substances that had little effect on abscission rates resulted in the production of negligible quantities of ethylene. Stimulatory action on abscission can be reduced by ventilation of the explants. It is concluded that endogenous ethylene participates in the abscission processes in bean-petiole abscission zones.
