Plasticity index and coefficient of variation ranking of physiological and ecological indicators of C. parva and C. scabrirostris in different environments. LA, leaf area; LRWC, leaf relative water content; SRL, specific root length; RTD, root tissue density; CUT, cuticle thickness; LET, lower epidermal thickness; LT, leaf thickness; SP, soluble protein concentration; POD, peroxidase activity; Chla/b, chlorophyll a/b; Chla+b, total chlorophyll content; Pnmax, maximum net photosynthetic rate in the light curve; LCP, light compensation point; RD, rate of dark respiration. (A) is the plasticity indicators in field environment, (B) is the coeffcient of variation index in field environment, (C) is the plasticity indicators in low-light environment, (D) is the coeffcient of variation index in low-light environment.
