In cut foliage and flowers, the vase life can be reduced by ethylene inducing the leaf yellowing or abscission. Low concentrations such as 0.5 μL L −1 can induce petal, bud, or leaf abscission in sensitive cut flowers. 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. graham and brown ltd blackburn
