英文摘要	Populus euphratica Oliv. and Populus pruinosa Schrenk are distributed on the banks of desert rivers in arid and semi-arid regions. By studying the variation of the structural and functional traits of P. euphratica and P. pruinosa with tree height, the differences in the structural and functional traits of the heteromorphic leaves were compared. The study determined the changes of the morphological structure, photosynthetic water physiology, osmotic adjustment substances and endogenous hormone content of the two species with the height of the tree. The results showed that with the increase of tree height, the leaf area (LA), leaf thickness (LT), palisade tissue thickness (PT), main vein xylem area (MXA), vessel area (VA), vessel number (VN) and net photosynthetic rate (Pn) of P. euphratica and P. pruinose, 613C, proline content, malondialdehyde (MDA) and endogenous hormone GA3, IAA, ZR content showed an increasing trend, and there was a significant positive correlation with tree height. The Pn at 10 m, the Tr at 6 m, 8 m, and 10 m, the 613C and the content of MDA, soluble protein, ABA, and IAA at each height for P. euphratica is significantly larger than P. pruinosa. These results suggested that P. euphratica have the more stronger ability to resistance to drought than P. pruinosa for its more invests in leaves, more xerophytic leaf morphology and anatomical structure, higher photosynthetic water use efficiency, stronger ability of osmotic adjustment
