The effect of EuCl3 on the growth of the callus was a biphasic one, with stimulation at low concentrations, and inhibition at higher concentrations. The explants would die when the concentration of EuCl3 was 100 mgL-1. The stimulative effect of EuCl3 could be inhibited by calmodulin antagonistchlorpromazine. 10 mgL-1 of EuCl3 would cause variations of the cell ultrastructure.展开更多
