L-IdnDH activity during grape berry development for the two vintages of the study. Error bars are standard errors of three biological replicates and three technical (spectrophotometric analysis) replicates. The developmental stage of veraison is indicated by a grey dotted box. (*: significant difference in Friedman test (α = 0.05)). a: data 2011 expressed in microkatal per gram of fresh weight (μkat.gFW-1); b: data 2013 expressed in microkatal per gram of fresh weight (μkat.gFW-1); c: data 2011 expressed in microkatal per berry (μkat.berry-1); d: data 2013 expressed in microkatal per berry (μkat.berry-1). FB: flowering beginning; PS: pea-sized; BC: bunch closure (berries touching); VB: veraison beginning (10 % ripe berries); VE: verasion end (80 % ripe berries); H: harvest (maturity)
