Plant height and leaf growth parameters of the three tomato cultivars under four days of control, drought, heat and combined stress. Different sub-graphs represent a plant height, b internode length, c leaf number, d leaf angle, e leaf area, f leaf temperature of the three tomato cultivars and phenotypes of g ‘Arvento’, h ‘LA1994’ and i ‘LA2093’ under control, drought, heat and combined stress. The data represent mean values ± SE (n = 4). Different small letters above the bars indicate significant differences (P < 0.05)
