Fig 1

Plants were either subjected to normal watering (control; grey columns) or to 14 days of withholding water (stress; black columns). Mean values ± SEM are shown (n = 3). Asterisks indicate significant (p≤0.05; *) or highly significant (p≤0.01; **) differences between mean values according to Tukey's tests made separately for each genotype (in case of the differences between control and stress treatment) or for each treatment (in case of the differences between both genotypes). BL … brassinolide, CS … castasterone, DS … dolichosterone, FM … leaf fresh mass, TY … typhasterol.
