Fig. 1: Effect of growth regulator treatments after berry set on berry properties during development and ripening in ‘Sable’.
From: Cytokinin but not gibberellin application had major impact on the phenylpropanoid pathway in grape
Berries were treated with GA, CPPU, and GA + CPPU after the berry set. a Diameter (mm), b °Brix, c weight (g), d titratable acidity (% TA), e berry appearance 34 d after treatment, f berry skin thickness (µm), and g representative berry sections stained with Safranin, from the Ctrl, GA, CPPU, and GA + CPPU 34 d after treatments. (a–d) Sample size was of 30 berries and values are the mean and standard deviation of three replications and the table in the panel indicates if the differences among treatment are significant by Tukey post-hoc test at p ≤ 0.05. Value in panel (f) are mean and standard deviation of 9 sections from 3 berries and different letters above each bar denote significant differences between the treatments. The horizontal black bar represents a size of 100 µm (g)
