Effect of ROS scavengers on germination of embryos treated by HCN

HCN treatment was carried out for 3 h before transferring the embryos to wet cotton wool at 10°C. ROS scavengers were applied continuously and their concentrations were 1 mm. Data are means of three replicates ± sd. SB, Sodium benzoate; ASA, ascorbic acid.
