摘要

Good berry color is an important characteristic of quality table grapes but the grapes are typically grown in warm climate regions where they are exposed to high temperatures during the ripening period, which inhibits berry coloring. Others have shownthat the natural plant hormone abscisic acid (ABA) accumulates in berry skins at the onset of ripening, and application of ABA at that time may hasten coloring. These observations prompted several studies to determine the effects of the plant growth regulator ProTone, the active ingredient of which is ABA, on Crimson Seedless grapes. Using this formulation of ABA, we found that application at veraison rapidly upregulated expression of a critical gene in the anthocyanin biosynthesis pathway, and the berries colored soon thereafter. 'Crimson Seedless' was responsive to ABA at veraison, and for several weeks thereafter. Efficacy generally improved with the quantity of ABA applied and coverage of the clusters. The most striking effect of treatment was improved berry color, but sometimes ABA also increased berry size, decreased acidity, and resulted in some berry softening. In a post-harvest study, treatment improved appearance, perhaps because the treated fruit colored more quickly, and therefore were harvested sooner, than non-treated fruit.
