不同光强下对马耳蕨叶绿素荧光参数的日变化
Diurnal changes of chlorophyll fluorescence parameters of Polystichum tsus-simense (Hook)J. Sm. under different light intensities
摘要
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 (CNPO) 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.关键词
