Fig. 5From: Role of exogenous-applied salicylic acid, zinc and glycine betaine to improve drought-tolerance in wheat during reproductive growth stagesInfluences of soil water conditions and foliar treatments on the accumulations of free proline content and total soluble sugar. Every column in each graph represents the mean (±SE) of three replicates. Various letters above columns indicate the significant differences among means (p < 0.05). WW, well-watered; WD, water-deficient; CK, control (double distilled water); SA, salicylic acid; Zn, zinc; GB, glycine betaineBack to article page
