Fig. 8From: Similar effects as shade tolerance induced by dust accumulation and size penetration of particulates on cotton leavesAn occlusive stoma by dust particles on the adaxial surface in cotton growing in the field under SEM a and EDS b images. The energy-dispersive spectrometer (EDS) showed the Si content. The scale is 10 μm. CLSM images of the foliar surface after 20 days by feeding 1 μm c, d, e and 0.1 μm f, g, h carboxylate-modified fluorospheres in 1-week-old cotton seedlings. C and F show fluorescence, D and G show SEM, and E and H are overlaps of the corresponding fluorescence and SEM images. The scale shown is 20 μmBack to article page
