Fig. 3From: New field wind manipulation methodology reveals adaptive responses of steppe plants to increased and reduced wind speedPlant size and shape traits of four plant species under different wind treatments. Plant height (a), projected crown area (b), root length (c) and STEPWISE bifurcation ratio(1:2) (d). Decrease, CK (ambient) and Increase refer to wind velocity treatments. Different lowercase letters indicate significant differences among treatments at p < 0.05. The error bars are plotted by means ± SEBack to article page
