摘要/Abstract

摘要：

非直角双曲线模型(简称模型I)是Farquhar、von Caemmerer和Berry提出的生物化学光合模型(简称FvCB生化模型)的主要子模型。在植物光合作用对光响应曲线的拟合中, 模型I得到广泛的应用和验证。同时, 模型I也可用于估算植物叶片的最大电子传递速率(J_max)。然而, 由模型I估算植物叶片的J_max是否与实测值相符, 尚未得到严格的验证。该文应用LI-6400-40光合测定仪测定了遮阴和全日照条件下大豆(Glycine max)叶片的光合速率和电子传递速率对光的响应曲线, 然后分别用模型I和电子传递速率对光响应机理模型(简称模型II)进行了拟合。结果表明, 由模型I估算遮阴和全日照条件下大豆叶片的J_max与观测值之间存在显著差异; 由模型II计算得到的J_max与实测值之间不存在显著差异。此外, 用模型I估算的J_max将高估光合电子流分配到光呼吸的量, 从而高估光呼吸对植物的光保护作用。因此, 在估算植物叶片J_max和准确评估光呼吸对植物光保护作用方面, 模型II更合理。

Abstract:

Aims The non-rectangular hyperbolic model (termed as model I) is the main submodel of the FvCB biochemical model, which is used to estimate the maximum electron transport rate (J_max) of plant leaves. The submodel is widely applied to fit the light-response curves of electron transport rate (J-I curves), and obtain J_max. However, it has not been strictly verified whether J_max calculated by model I is consistent with the measured values.

Methods Light-response curves of electron transport rate and of photosynthesis rate of soybean (Glycine max) (under shading and full sunlight) were simultaneously measured by LI-6400-40, then these data were simulated by model I and the mechanistic model of light-response of electron transport rate (termed as model II).

Important findings The results showed that there was the significant differences between J_max estimated by model I and the observation data irrespective of shading and full sunny leaves of soybean. However, there was no significant difference between J_max calculated by model II and the measured value. Because J_max was overestimated by model I, it must lead to overestimate the amount of photosynthetic electron flow to allocate to photorespiration pathway, and magnify the photoprotection of photorespiration on plants. On the contrary, the J_max and saturation light intensity (PAR_sat) obtained by the model II were in very close agreement with the observations. It can be concluded that the model II was superior to the model I in estimates of J_max and PAR_sat. Therefore, we recommend model II to be used as an operational model for fitting J-I curves and accurately assess the role of photorespiration on plant photo-protection.
