Comparative Analyses of Physiological Responses of Cynodon dactylon Accessions from Southwest China to Sulfur Dioxide Toxicity
Figure 4
Comparison of chlorophyll a (a), chlorophyll b (b), total chlorophyll (c), and carotenoid (d) in leaves from nine selected C. dactylon accessions in response to SO2 stress. Mean values are presented with vertical error bars representing the standard deviations (). The asterisk symbols indicate significant differences between SO2-sensitive accessions and SO2-tolerant accessions.
