Postharvest dip in a natural lipid, lysophosphatidylethanolamine, may prolong vase life of snapdragon flowers.

The use of lysophosphatidylethanolamine (LPE) for prolonging vase life of Antirrhinum majus was investigated using cv. Potomac White and a long-duration inbred line. Freshly cut spikes were set into a LPE solution at 25 mg/litre for 24 h and then transferred to deionized water. The vase life was enhanced by LPE. The flowers on spikes treated with LPE showed symptoms of wilting or browning 4 or 6 days later than those on the spikes given deionized water in the inbred line or Potomac White, respectively. All the spikes were of marketable quality for 5-7 days after harvest when treated with LPE, whereas in the control only about half of the flowers were of marketable quality at 2 days after harvest. LPE treatment also delayed fresh weight loss, lowered endogenous ethylene production, and reduced ion leakage. These results suggest that LPE has commercial potential in enhancing vase life of A. majus.
