Effect of drought, heat, and combined drought and heat on height (%), fresh weight (FW) (%), and dry weight (DW) (%) of four eggplant cultivars. Results are expressed as percentage of control.

The values are means (±standard errors) of four repetitions. Different lowercase letters within each treatment (n = 4) represent significant differences among cultivars, based on Student’s t-test at 5 % level. (C, control; H, heat stress; D, drought stress; H + D, heat + drought stresses).
