Effect of floral cluster pruning on anthocyanin levels and anthocyanain-related gene expression in 'Houman' grape.

ABSTRACT: Lateral floral clusters were removed from the main axis of the floral clusters of 'Houman' grape plants, leaving only 3-5-cm-long region of flowers at the end of the central axis. The floral clusters were pruned at 7 days prior to flowering. The effect of the pruning on fruit quality was assessed by determining the composition and levels of anthocyanins in the fruit and anthocyanin-related gene expression. Results indicated that floral cluster pruning significantly improved the quality of the fruit by increasing berry size, fruit weight and the total content of soluble solids. Floral cluster pruning also decreased the level of titratable acidity. Sixteen different anthocyanins were detected in fruit of the pruned clusters, while only 15 were detected in fruit from unpruned clusters. The le
