Recovery of 14C-labeled products in grapevine tissue after infiltration of 14C-labeled precursors to the excised bunch stem. Two-way ANOVA with Bonferroni Post-test was performed using GraphPad Prism 5.01 (San Diego, California). The mean values with different letters above the SEM bars indicate significant differences between the proportions of radiolabelled substrates recovered in a specific product (P < 0.05). V. vinifera c.v. Shiraz bunches with 3 cm rachis attached were collected at 32 DAF. Data is presented as recovery of each 14C-labeled form in either the berry or rachis/stem as a percent of that same 14C-labeled form recovered in all tissues. n = 4, SEM bars. A. Recovery of 14C-labeled products in the berries and B. Recovery of 14C-labeled products in the combined rachis and stem tissue.
