Chlorophyll a (A), Chlorophyll a (B), Chlorophyll a + b (C), and leaf relative water content (D) under drought and heat stress. The differences between treatments in each parameter were detected by one-way ANOVA at p < 0.05 level. Bars represent mean ± SD (n = 3). Columns marked with same small letter (a, b, c) indicate insignificant differences between four treatment groups (p < 0.05). CK represents control, F represents A. aculeatus, D represents drought, DF represents drought + A. aculeatus, HT represents heat, and HTF represents heat + A. aculeatus.
