英文摘要	Populus pruinosa Schrenk. (P. pruinose) has the biological characteristic of heteromorphic leaves, which is related to growth and adaptation to extreme arid environments. The present study aimed to clarify whether carbohydrate and endogenous hormone content had an effect on the morphological structure of P. pruinose heteromorphic leaves on canopy height during ontogenesis. Petiole length, upper epidermal cell length, upper epidermal cell number, lower epidermal cell length, palisade tissue cell number, palisade tissue thickness, palisade tissue cell width and palisade tissue/spongy tissue ratio were very significantly positively correlated with diameter at breast height (DBH) and canopy height. Spongy tissue thickness is significantly negatively correlated with diameter at breast height and canopy height, with advancements in the developmental stage and increase in canopy height, the heterophil xerophytic structure is more and more obvious. Zeatin-riboside content and zeatin-riboside/abscisic acid ratio positively correlated with diameter at breast height, while gibberellin/abscisic acid ratio negatively correlated with canopy height. Soluble sugar and soluble protein contents significantly positively correlated with diameter at breast height and canopy height, starch contents significantly negatively correlated with diameter at breast height and canopy height. Regression analysis showed that soluble sugar content had positive effects on petiole length, leaf width, leaf area, leaf circumference, leaf thickness, upper epidermal cell length, lower epidermal cell number, palisade tissue thickness and spongy tissue thickness. The soluble protein content had a positive effect on leaf index and palisade tissue/spongy tissue ratio, starch content had a positive effect on upper epidermal cell width and palisade tissue thickness. It was concluded that the endogenous hormone and carbohydrate content could enhance the xerophytic structure of heteromorphic leaves during ontogenesis.
