Introduction
Plant hormones function as integrators of extracellular signals, to mediate physiological and developmental adaptations throughout a plant's life cycle. They can be divided into growth stimulators comprising auxin, cytokinin, giberrelin and brassinosteroid, as well as growth inhibitors such as salicyclic acid, abscisic acid and ethylene.
Effects of Ethylene On Senescence
Ethylene has a myriad of effects on plant development, most notably in fruit ripening and senescence of flowers. Being gaseous, its hormonal effects also affect adjacent plants.
