Fig. 1. Winter … WebThe effect of ethylene on quality losses of cut flowers is due to the petal wilting or abscission or color fading. 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.
