Abstract:: The transpiration characteristic and its samples selected from 8 varieties of poplar clones were studied based on the observation induced in Gaomi city east of Shandong province. The results show that the rate of water consumption by transpiration daily changing tendency of 8 poplar clones is gnenerally unanimous with single apex curve. The order of the size of the rate of water consumption by transpiration and environmental factors associated analysis is: illumination > air relative humidity > temperature > soil moisture content. The water consumption of transpiration is of the following order,L35 > I-107 > NL895 > Zhonglin46 > I-109 > L323 > Zhongsui12 > NL95.All of 8 poplar clones can be categorized into five groups according to water consumption of transpiration and volume increment, L35 belongs to the highest water consumption of transpiration and volume increment; L323, NL95 and I-109 belong to medium volume increment and lower water consumption of transpiration; NL895 belongs to lower volume increment and the lowest water consumption of transpiration; I-107 belongs to higher volume increment and water consumption of transpiration; Zhonglin46 and Zhongsui12 belong to the lowest volume increment and medium water consumption of transpiration.
