Effects of alkaline treatment on physiological characteristics. a-c Changes in proline concentration, malondialdehyde (MDA) level, and peroxidase (POD) activity in leaf samples harvested from 0-day, 3-day, and 7-day treated plants. C represents control samples, ST represents 3-day alkaline treated samples, and LT represents 7-day alkaline challenged leaves. The error bar suggests SDs across 2 different biological duplicates (n = 3). Asterisks represent significant differences in alkaline-challenged leaves compared with controls (*P < 0.05; **P < 0.01)
