Data were taken following 0, 3, 24 and 48 h of PEG treatment. Each percentage value is the mean of 5 plants. For each sampling time, data were subjected to a one-way analysis of variance to compare the different varieties. Different letters in the same column show significant differences based on a Tukey’s test (p ≤ 0.001)
