Abstract:: The transpiration rate with their influencing factors was studied based on the observation and research of the samples selected from 7 varieties of poplar clones induced in Gaomi city in Shandong province. The results show that general daily changing tendency of 7 poplar clones is generally unanimous with single-apex curve. In addition, changing tendency of transpiration rates is just the same as that of the stomatal conductance. The daily the biggest transpiration rates are of the following order, TrI-107 > Tr NL95 > Tr L35 > Tr L323 > Trzhonglin46 > Trzhongtianyang > Tr NL895,The daily average transpiration rates are of the following order, Tr I-107 > Tr L35 > Tr NL95 > Tr L323 > Trzhonglin46 > Trzhongtianyang > Tr NL895. The mutuality between transpiration rate and stomatal conductance is the most prominent. The relationship between stomatal conductance and transpiration rate with their influencing factors are multivariate linear function, transpiration rates of 7 poplar clones have positive correlation with the H,D and V.
