Fig. 5From: Flavonoids and darkness lower PCD in senescing Vitis vinifera suspension cell culturesATP content in V. vinifera (cv. Limberger) suspension cell cultures. GSC and RSC were grown under light or dark conditions for 6 days, and sampled at day 0, 3 and 6, respectively (Panel a). Necrotic- and apoptotic-like samples, used as positive controls, were obtained on GSC at day 0, after incubation at 80 °C for 10 min or with 10 % (v/v) ethanol for 24 h, respectively (Panel b). Bars are means ± S.D. of at least three independent experiments. Different letters indicate significant difference (P ≤ 0.05), evaluated by ANOVA testBack to article page
