Fig. 2.
Illustrates the impact of ABA application on stomatal conductance (m mol−2 s−1), water use efficiency (%), and Chlorophyll a and b (mg g−1 FW) contents at critical growth stages of wheat under drought stress. The labels CK, DGFS, DFS, and DTS represent the control as no drought at any stage, drought at grain filling, flowering, and tillering stages, respectively. ABA0, ABA1 and ABA2 indicates control, 100mgL−1 and 200 mgL−1 ABA application respectively. The error bars in the figure indicate the standard error (n = 3).
