Fig. 7From: Transcriptome analysis reveals a positive effect of brassinosteroids on the photosynthetic capacity of wucai under low temperatureEffects of exogenous EBR application on photosynthetic pigment contents in wucai leaves under LT stress. (A–C) Quantification of the Chl a content (a), Chl b content (b), Total Chl content (c), and the Chl a/b ratio calculated from A and B (d). The data are presented as the mean ± SE. Bars with different letters above the columns indicate significant differences (p < 0.05, Duncan’s range test) on a given day of treatmentBack to article page
