WebEthylene is a gas biosynthesized by plants which has many physiological and developmental effects on their growth. Ethylene affects agriculturally and horticulturally important traits such as fruit ripening, post-harvest physiology, senescence, and abscission, and so ethylene action is often inhibited to improve the shelf life of fruits, vegetables, and cut flowers. WebAs concentrations of ethylene increase, flower buds will also abscise. When salvia are exposed to ethylene for 24 hours, even 0.01 ppm ethylene results in the loss of a few petals. Increasing amounts of ethylene cause more flower abscission, with 1 and 10 ppm ethylene resulting in the loss of 50 to 85 percent of the petals, respectively (Figure 3). WebAbstract.
