What is meant by dehicence of dry fruits? and how it is affected by ethylene?
Dear student,
Dehiscence is the spontaneous splitting open of a plant structure on maturation. For example, the fruits on maturation dehisce to release seeds. Ethylene along with ABA involve in the promotion of normal floral organ abscission through the manipulation of genes encoding cell wall hydrolysis enzymes such as polygalacturonase. The supression of those gene causes to extend fruit firmness during ripening and thus formed a dehiscence zone in dry fruits.
