Effects of exogenous zeaxanthin on electrolyte leakage, relative water content and growth of pepper leaves under low temperature combined with low-light stress. (A): electrolyte leakage; (B): relative water content; (C): growth of pepper. CK: the pepper was sprayed with distilled water under normal conditions, CK + Z: the pepper was sprayed with zeaxanthin under normal conditions, LL: the pepper was sprayed with distilled water under low temperature combined with low-light stress, and LL + Z: the pepper was sprayed with zeaxanthin under low temperature combined with low-light stress. The values were presented as means ± standard deviations (SDs; n = 3). The different letters above bars indicated significant difference at p < 0.05 in the same period among treatments.
