叶温

光合作用最适叶温为28℃。

The optimum leaf temperature of photosynthesis was 28 ° C.

叶温的变化反映了作物自身的水分状况。

The variance of leaf temperature reflects the condition of water content in the crop .

其中，气孔导度、蒸腾速率、叶温、光合有效辐射及基于叶温的蒸汽压亏缺是大豆光合作用的促进因子；细胞间CO2浓度、空气中CO2、空气相对湿度为主要的限制因子。

Stomata conductance , transpiration rate , temperature of leaf , photosynthetic was promoting factors for bean leaf ; intercellular CO2 concentration , CO2 of air and air relative humidity were mainly limiting factors . 3 .

当空气相对湿度较为适中时，叶温的影响较小，在空气相对湿度变坏的情况下，叶温才对光合午休有重要影响。

The effect of leaf temperature was important when and only when the air relative humidity was very low .

研究不同土水势值对油菜的生长发育状况和叶水势、叶温、叶气孔阻力、蒸腾强度、叶细胞液浓度等生理性状，以及油菜的经济产量和生物学产量的影响。

The effects of three soil water potentials on the growth , leaf water potential , leaf temperature , leaf stom - atal resistance , transpiration rate , leaf cell sap consistance and economic and biological yield of rape were investigated .
