【Objective】In order to make clear the effects of adverse environment on the damage of fruit tree leaves,the soluble protein,proline and soluble sugar were determined under the condition of dust and shade stress.【Method】Juglans regia,Armeniaca vulgaris,Amygdalus communis and Malus pumila were selected as material,orthogonal experiments were designed under the different artificial conditions(dust 3 mg/cm2 and 9 mg/cm2,shading 16. 4% and 46. 5%) and treatment times 9 d,18 d,27 d,36 d were set to analyze the impact of different treatments on the osmotic adjustment substances of leaves.【Result】Under the light dust treatment,the four kinds fruit tree leaves proline and soluble sugar content increased gradually,but soluble protein increased first and then declined. The contents of proline,soluble sugar and protein reached the peak value 9-18 d,and then decreased under the heavy dust stress. The osmotic adjustment substances increased to different degrees under the light shading treatment,but increased first and then decreased under the heavy shading treatment.【Conclusion】Ust and shading stress brings some adverse effects on 4 kinds of fruit tree leaves.
