Relationship between leaf transpiration rate of Lycium barbarum L. And its physiological factor as well as environmental micrometeorological factors

By modeling the relationship between transpiration rat e and some factors respectively, the relationships between leaf transpiration rate and the factors such as photosynthesis rate, stoma conductance, etc. are studie d. The results show that there are close relationships between leaf transpiratio n rate, and leaf and air temperature, relative humidity, difference of vapor pre ssure, stoma conductance radiation and CO 2 density difference. Upon this e nvironmental, micrometeorological factors, the leaf and air temperature, relativ e humidity have high influence on the leaf transpiration rate, the total solar r adiation has low influence, the wind is lower as it is weakly.
