Fig. 10From: Drought-hardening improves drought tolerance in Nicotiana tabacum at physiological, biochemical, and molecular levelsThis schematic flow shows the setup of the experiment. Drought-hardening was applied to two tobacco variety seedlings and then subjected to drought stress. H and Y representing HongHuaDaJinYuan and Yun Yan-100, respectively. CK representing control/non-drought-hardened plants; T1 represents drought-hardening for 24 h; T2 represents drought-hardening for 48 h; T3 represents drought-hardening for 72 h. Trays with blue color present normal water conditions, while trays with white color present seedlings under drought stress conditionsBack to article page
