Preventing Leaf Yellowing of Fresh Cut Oriental Hybrid Lilies
Since it occurs prior to flower senescence, postharvest leaf injury of cut Oriental hybrid lilies is a major problem. This detracts from the overall appearance of the flower stem and adversely affects quality and customer satisfaction. Symptoms can occur after storage or upon arrival to the florist, but most often are manifested after plants have been maintained in an interior consumer environment.
