高温胁迫对茶树叶片光合系统的影响

Abstract

Abstract: To study the effects of heat stress on the photosynthesis system of tea plant (Camellia sinensis L.), seedlings of ‘Longjing 43’ cultivar were challenged with high temperature (43℃) for 48 h followed by observation of photosynthetic apparatus by using Imaging Fluorescence system and Dual-PAM. Results obtained were as follows: Heat stress caused obvious alterations in the leaf phenotype. Net photosynthetic rate declined gradually following heat stress which was accompanied with significant decreases in the maximum carboxylation rate of Rubisco and the maximum RuBP regeneration rate. Heat stress decreased Fv/Fm, Y(Ⅰ) and Y (Ⅱ) rapidly, but increased Y(NO) and Y (NA), indicating that both photosystem II and photosystem I were damaged by heat stress. Φ_PSⅡ, ETR(Ⅱ) and ETR(Ⅰ) were also decreased significantly by heat stress, suggesting that heat stress possibly blocked the electron transduction, in tea leaves, photosystem I was more tolerant to heat stress, while photosystem II was relatively sensitive.

Key words: heat stress, Camellia sinensis, Fv/Fm, PSI, PSⅡ
