Preventing Ethylene Injury to Fresh Cut Flowers
Ethylene is the “silent killer” to fresh cut flowers. It is a natural plant hormone that regulates many plant functions, e.g., fruit ripening and plant senescence. However, when plants are exposed to external ethylene from sources; e.g., truck exhaust; heaters; cigarette smoke; and ripening fruit; flowers, buds, and leaves of cut flowers can be adversely affected. Buds and flowers can turn yellow, wilt, and/or drop. Buds may fail to open and flowers die prematurely.
