source and sink in controls and the F₂ progenies. a sucrose transport (source). b CWI activity was measured in the central parenchyma-rich zone (sink). c in the peripheral vascular-rich zone (sink). d in separated vascular bundles and parenchyma tissue from the central zone of internode 5 (sink). Three controls: Rio (parental control), T×430 (untransformed control), LR24 was transgene negative F₂ progeny as the hybrid control. Three high-sugar transgene F₂ positive progenies: LR3, LR19, and LR20. CCCP: carbonyl cyanide m-chlorophenyl hydrazone. The leaves and internodes were sampled at 20 days after anthesis. Results are means with standard errors from three replicates. Analysis of variance (ANOVA) with Bonferroni post-tests showed significant differences between any control and high-sugar progenies in the sucrose transport rates at all time points. The same statistical analysis showed significant differences between controls and high-sugar progenies in CWI activity of parenchyma cells in the central zone. *P < 0.05; **P < 0.01; ***P < 0.001
