Fig. 6From: Flavonoids and darkness lower PCD in senescing Vitis vinifera suspension cell culturesReactive oxygen species (ROS) formation in V. vinifera (cv. Limberger) suspension cell cultures. ROS generation was estimated as fluorescence intensity generated by H2DFCA in GSC and RSC at day 0. Cell cultures were incubated in the absence (Panel a) or presence (Panel b) of 1 mM ABAP. Insets represent the total amount of dead cells, evaluated by FDA staining at either 0 and 105 min. Bars are means ± S.D. of at least three independent experimentsBack to article page
