The effects of shading on chlorophylls and daily environmental parameters in shading experiment in tea plantation. a The set up of shading treatments in tea plantation. b The effects of shading on appearance of tea leaves after 14 days. c The effects of shading on chlorophylls after 14 days. d The effects of shading on daily environmental parameters among different treatments in tea plantation. The treatments are: tea plants with naturally growth (Control); tea plants with 50–60% shading treatment (S50–60%); tea plants with 80–90% shading treatment (S80–90%). PAR, photosynthetic actively radiation; Chla, chlorophyll a; Chlb, chlorophyll b; ns, no significance. Data shown are the average mean ± SE of three replicates (n = 3). *Significant differences comparing the Control treatment at each time point according to one-way analysis of variance (ANOVA) test and a Fisher’s least significant difference (LSD) at the 5% significance level (*p < 0.05, **p < 0.01). Different letters (a, b, c) indicate statistical significance among treatments using one-way ANOVA and a Fisher’s LSD test at the 5% significance level
