Fig. 3From: Differences in the photosynthetic and physiological responses of Leymus chinensis to different levels of grazing intensityThe chlorophyll a (Chl a), chlorophyll b (Chl b), and carotenoid (Car) contents, total chlorophyll content (Chl a + b), chlorophyll a/b ratio (Chl a/b), and Rubisco activity in leaves of L. chinensis in the plots with different grazing intensities (control, no grazing; LG, light grazing; MG, medium grazing; HG, heavy grazing). Values are means ± SE (n = 3). Values of a parameter labeled with different letters differ significantly between grazing intensities (ANOVA followed by LSD test, P < 0.05)Back to article page
