a The correlation between three phospholipids and membrane ion leakage based on Spearman’s correlation analysis. b The correlation between the alteration of photosynthesis rate and dynamic changes of galactolipids. Phospholipids profiles and membrane ion leakage, as well as galactolipids profiles and photosynthesis of leaves after PEG treatment for 0 d, 1 d, 2 d, 3 d, 4 d were analyzed by Spearman’s correlation here. All molecular species meet criteria were analyzed here (Criteria: the amount of molecular species is more than 0.0005 nmol, coefficient of variation (st. dev./average) for identical samples, made by pooling samples, is less than 0.3)
