This study aimed to determine the photosynthetic performance and differences in chlorophyll fluorescence (ChlF) parameters between and its companion species and when subjected to different photosynthetic photon flux density (PPFDs). Leaf surfaces were then illuminated with 50, 100 (low PPFDs), 300, 500, 800 (moderate PPFDs); 1,000; 1,500; and 2,000 (high PPFDs) μmol m·s, and the ChlF parameters were measured during the whole process. Increasing nonphotochemical quenching of ChlF and decreasing potential quantum efficiency of PSII, actual quantum efficiency of PSII, and quantum efficiency ratio of PSII in dark recovery from 0-60 min were observed in all leaves. A significant and negative relationship was detected between energy-dependent quenching (q) and photoinhibition percent in three species under specific PPFD conditions, whereas a significant and positive relationship was detected between photoinhibitory quenching (q) and photoinhibition percent. The q and q can be easily measured in the field and provide useful ecological indexes for species restoration, habitat creation, and monitoring.
本研究旨在确定[物种名称1]及其伴生种[物种名称2]和[物种名称3]在不同光合光子通量密度（PPFD）下的光合性能及叶绿素荧光（ChlF）参数差异。然后用50、100（低PPFD）、300、500、800（中等PPFD）、1000、1500和2000（高PPFD）μmol m⁻²·s⁻¹照射叶片表面，并在整个过程中测量ChlF参数。在所有叶片中均观察到ChlF的非光化学猝灭增加，以及从0至60分钟黑暗恢复过程中PSII的潜在量子效率、PSII的实际量子效率和PSII的量子效率比降低。在特定PPFD条件下，三种物种的能量依赖性猝灭（qE）与光抑制百分比之间存在显著负相关，而光抑制猝灭（qI）与光抑制百分比之间存在显著正相关。qE和qI可在野外轻松测量，并为[物种名称1]的物种恢复、栖息地创建和监测提供有用的生态指标。
