Leaf, shoot, and root total soluble sugar (SS) (A–C) and starch (D–F) contents of Cabernet Sauvignon grapevines (clone FPS08), subjected to different replacements of crop evapotranspiration (25% ETc, 50% ETc, and 100% ETc) during two growing seasons (2019 and 2020) and collected in October 2020 in Oakville, CA, United States. Values represent means ± SEM (n = 6). Different letters indicate significant differences (p ≤ 0.05) between irrigation treatments according to one-way ANOVA followed by Duncan’s new multiple range test. * and *** indicate significance at 5 and 0.1% probability levels, respectively.
