Effect of drought-hardening on the non-enzymatic antioxidant defense system in response to drought stress. Drought stress-induced changes in the contents of antioxidant substances, AsA (a) and GSH (b) of the two tobacco varieties of various drought-hardening treatments seedlings along with non-drought-hardened seedlings. The error bars on each mean value are ± SDs, different letters indicating significant differences at p < 0.05 by LSD test. HCK represents HongHuaDaJinYuan seedlings with no drought-hardening; HT1 indicates 24 h drought-hardened seedlings of HongHuaDaJinYuan; HT2 indicates 48 h drought-hardened seedlings of HongHuaDaJinYuan; HT3 indicates 72 h drought-hardened seedlings of HongHuaDaJinYuan; YCK represents Yun Yan-100 seedlings with no drought-hardening; YT1 indicates 24 h drought-hardened seedlings of Yun Yan-100; YT2 indicates 48 h drought-hardened seedlings of Yun Yan-100; YT3 indicates 72 h drought-hardened seedlings of Yun Yan-100
