Abstract

The temperature which affects plant growth and development, is an important ecological factor. In the present study, we mainly aimed to study the effects of temperature on gas exchange characteristics in the leaves of Lonicera Japonica Thunb., The results showed that light elevated temperature had no significant effects on the photosynthesis of L. japonica (Lonicera Japonica), which was well indicated by the responses of net photosynthesis rate (P_N), stomatal conductance (G_s), intercellular CO₂ concentration (C_i) and transpiration rate (E). Intercellular CO₂ concentration and transpiration rate had a good relationship with stomatal conductance. The study will provide a reference for L. japonica to response temperature warming and be useful for environmental protection.
