Use of natural lipids to accelerate ripening and enhance storage life of tomato fruit with and without ethephon.

Processing tomato cv. Heinz 7155 plants were sprayed to run-off with ethephon at 1000 mg/litre, a 1% lysophosphatidylethanolamine (LPE) solution in ethanol, or water (controls) about 2 weeks before harvest. The percentage of acceptable (firm and well-ripened) fruits was similar in the ethephon and LPE treatments (50.1 and 49.5%, respectively, compared with 17.6% in controls), but leaves sprayed with ethephon were dead, whereas those sprayed with LPE were only somewhat yellow (as were the controls). Firm fruits were stored for 5 days at 22 deg C. LPE treatment resulted in a higher percentage of firm fruits after storage than the controls (55.2 vs. 28.4%, respectively), and a lower percentage of rotten, spotted or mouldy fruits than the ethephon treatment (6.1 vs. 23.2%, respectively). In a similar trial, 100 mg ethephon + 100 mg LPE/litre resulted in a higher percentage of acceptable fruits and a lower percentage of green fruits at harvest, and also enhanced the postharvest storage quality of acc

eptable fruits, compared with controls. Similar results were obtained in trials on cv. Glamour (for the fresh market). Neither phosphatidyldimethylethanolamine dipalmitoyl nor phosphatidylethanolamine (cv. Heinz 7155 trials) were quite as effective as LPE at accelerating ripening and prolonging storage life.
