Chlorophyll florescence parameters and the content of D1 protein in Satsuma mandarin (Citrus unshiu Mac.) leaves that fed with 0.01 mol/L lincomycin or water and illuminated with different light intensities for 5 hours were determined by PAM-2000 Chlorophyll Fluorometer and Western-blotting technique respectively.The results showed illumination with 500 or 1 500μmol·m~(-2)·s~(-1) significantly decreased that maximum photochemical efficiency (F_v/F_m) and this depression was more significant in the presence ...
