| الوصف: | The heat tolerance of tomato seedlings was significantly enhanced after heat shock treatment at 40°C for 4 h. Compared with the control, the heat-shocked tomato seedlings, on one hand, had a higher net photosynthetic rate (PN), stomatal conductance, intercellular CO2 concentration, water-use efficiency, maximal quantum yield of PSII photochemistry (Fv/Fm), electron transport rate, actual photochemical efficiency of PSII, and activity of antioxidant enzymes, on the other hand, had lower nonphotochemical quenching, relative conductivity, malondialdehyde content (MDA), and accumulation of reactive oxygen species (ROS). In addition, heat shock induced production of heat shock proteins (HSPs) in tomato seedling leaves. HSP70 was significantly negatively correlated with PN, Fv/Fm, catalase, superoxide dismutase, and peroxidase and was significantly positively correlated with MDA and ROS. Overall, short-term heat shock treatments, inducing the production of HSPs, helped improve the thermal tolerance of tomato seedlings. |
