Abstract:
Under full sunlight and 7 % of sunlight, daily variations of chlorophyll fluorescence parameters were explored in Polystichum tsussimense. The results showed that after sunrise the maximal efficiency of PS Ⅱ(Fv/Fm), the excitation capture efficiency of PS Ⅱ(Fv′/Fm′) and photochemical quenching(qP) decreased in P. tsussimense under full sunlight, at 15:00 Fv/Fm and qP were the lowest, at 13:00 Fv′/Fm′ was the lowest. However, the relative electron transport rate (rETR) and nonphotochemical quenching (CNPQ) increased and the highest were at 11:00. These 5 parameters could not be recovered until next morning. Under 7% of sunlight RETR increased after sunrise and the higest was at 11:00, but other 4 parameters changed little all the day. Results suggest that P. tsussimense has photoprotective and grows well under full sunlight. Thus this plant is not a typical shade ferns.
