Fig. 1From: Effects of repeated drought stress on the physiological characteristics and lipid metabolism of Bombax ceiba L. during subsequent drought and heat stressesChanges of soluble sugar content in Bombax ceiba L. treated with dehydration and heat shock. Seedlings were subjected to air drying for 2 h at 28 °C (the first dehydration stress, D1) followed by full rehydration recovery for 22 h. After two cycles of dehydration/rehydration, seedlings were exposed to the third dehydration stress (D3) or treated at 48 °C for 2 h (D2H). Heat-treated seedlings (H) were directly treated at 48 °C. Within the same experiment, different letters indicate significant differences between treatments (P < 0.05). Data are represented as mean ± standard deviation (n = 5)Back to article page
