Table 1 Effects of DCPTA (5, 15, and 25 mg/L) with or without 15% PEG-6000-induced drought stress on the fresh and dry weights of the shoots and roots and the leaf area. The values represent the mean ± SE (n = 5). Values with the same letters in the columns are not significantly different at P < 0.05 (LSD test).
