Muskmelon (Cucumis melo L.) fruit ripening and postharvest quality after a preharvest spray of aminoethoxyvinylglycine

Aminoethoxyvinylglycine (AVG) at 60, 130, or 260 mg l-1 was applied to plots of `Primo' and `Mission' muskmelon 18 or 12 days prior to harvest. Melons were harvested twice from each plot and quality attributes evaluated at harvest or after cold storage. Melons harvested from plots sprayed with AVG had lower rates of ethylene production at harvest and after cold storage than melons harvested from control plots. Melon ethylene production after storage varied inversely with AVG application rate and was consistently lower when AVG was applied 7 days after full net. No difference was observed in flesh firmness, soluble solids, fresh mass or incidence of decay at harvest or after storage in melons harvested from plots sprayed with AVG. Uniformity of melon maturity within a plot was not enhanced by AVG, and plots treated with AVG required sequential harvests similar to control plots. Applications of 260 mg l-1 of AVG did, however, delay initial development of an abscission zone. Plots sprayed with 130 or 260 mg l-1 AVG developed a dose- related, leaf chlorosis readily visible 4 days after spraying. Plants with leaf chlorosis were rated equal in vigor to plants without leaf chlorosis.
