| 英文摘要 | Background: The electron transport chain, Rubisco and stomatal conductance are important in photosynthesis. Little is known about their combined responses to heat treatment at different temperatures and following recovery in grapevines (Vitis spp.) which are often grown in climates with high temperatures. Methodology/Findings: The electron transport function of photosystem II, the activation state of Rubisco and the influence of stomatal behavior were investigated in grapevine leaves during heat treatments and following recovery. High temperature treatments included 35, 40 and 45 degrees C, with 25 degrees C as the control and recovery temperature. Heat treatment at 35 degrees C did not significantly (P>0.05) inhibit net photosynthetic rate (P-n). However, with treatments at 40 and 45 degrees C, P-n was decreased, accompanied by an increase in substomatal CO2 concentration (C-i), decreases in stomatal conductance (g(s)) and the activation state of Rubisco, and inhibition of the donor side and the reaction center of PSII. The acceptor side of PSII was inhibited at 45 degrees C but not at 40 degrees C. When grape leaves recovered following heat treatment, P-n, g(s) and the activation state of Rubisco also increased, and the donor side and the reaction center of PSII recovered. The increase in P-n during the recovery period following the second 45 degrees C stress was slower than that following the 40 degrees C stress, and these increases corresponded to the donor side of PSII and the activation state of Rubisco. Conclusions: Heat treatment at 35 degrees C did not significantly (P>0.05) influence photosynthesis. The decrease of P-n in grape leaves exposed to more severe heat stress (40 or 45 degrees C) was mainly attributed to three factors: the activation state of Rubisco, the donor side and the reaction center of PSII. However, the increase of P-n in grape leaves following heat stress was also associated with a stomatal response. The acceptor side of PSII in grape leaves was responsive but less sensitive to heat stress. |
