Fig. 5From: Similar effects as shade tolerance induced by dust accumulation and size penetration of particulates on cotton leavesSpecific leaf area (cm2 g− 1) a and leaf thickness (μm) b of cotton leaves in the control, and after dust accumulation (light, medium, and heavy). The values shown are the mean of 4 replicates. Bars represent the standard error. Different letters indicate significant differences among the treatments at a 0.05% levelBack to article page
