Abstract

Abstract: The Veronica undulata and Hippuris vulgaris in Jiuzhaigou were selected to examine diurnal variations of the maximum photochemical efficiency (F_v/F_m) and actual photochemical efficiency (Φ_PSⅡ) of PSⅡ, relevant parameters of rapid light curves (RLCs), photochemical quenching (qP) and non-photochemical quenching (NPQ) using pulse-amplitude modulated fluorometer (Junior-PAM) in Grass Lake. The purpose was to investigate the photosynthetic characteristics of these two submerged macrophytes and their adaptive strategies against environmental in alpine lakes. The results showed that the diurnal variations of Veronica undulata and Hippuris vulgaris of maximum relative electron transport rate (rETR_max) and half-saturation light intensity (E_k) presented typical unimodal curve. The F_v/F_m and Φ_PSⅡ of two submerged macrophytes showed V pattern diurnal cycle, F_v/F_m and Φ_PSⅡ were the highest at sunrise and sunset and the lowest at noon. The daily averages of rETR_max, E_k, qP and NPQ of Veronica undulata were significantly greater than those of Hippuris vulgaris. Therefore, Veronica undulata was macrophytes with strong capacity of light energy utilization and dissipation. A higher initial slope (α), chlorophyll b (Chlb) content and lower E_k in Hippuris vulgaris implied that it had higher capture light capacity and photosynthetic efficiency under weak light condition. In summary, significant differences in chlorophyll fluorescence parameters were found between Veronica undulata and Hippuris vulgaris, and Veronica undulata displayed more tolerance to strong light intensity than Hippuris vulgaris, it had a stronger ability for adaptation to local environment.

Key words: rapid light curves, submerged macrophytes, Veronica undulata, Hippuris vulgaris, photochemical quenching
