Impact of drought treatment on the growth of camphor seedlings.
Note: Lowercase letters (a, b, c, d) above the bars indicate significant differences (P<0.05) among the shading treatments. The bars represent mean values with standard error (±SE) (n = 9).

Effects of drought treatment on PSⅡ donor side/recipient side and overall PSⅡ/PS I performance of leaves.
Note: Lowercase letters (a, b, c, d) above the bars indicate significant differences (P<0.05) among the shading treatments. Bars represent mean values with standard error (±SE) (n = 9).
