Abstract：The method of division in canopy was used for studying the effect of distribution of relative light intensity in the different tiers of tree canopy on the production and fruit quality of Conference pear cuhivar.The results showed that the dis-tribution of relative light intensity in the canopy gradually descended from upper to lower tier.In the same tier, the relative light intensity was increased from inner to outer.Less 30% of the relative light intensity distributed mainly in the lowest tier of canopy.The yield distributed mainly from 1.0 m to 2.5 m height of the canopy.And the fruit mass,flesh firmness ,titratable acidity was positively correlated to relative light intensity.The regression equations in relationship between relative light in-tensity and production and fruit quality was established.The optimum relative light intensity was 67.2% for high yield ,56.5% for fruit mass, 58.2% for flesh firmness, 55.0% for soluble solid content,and 39.7% for titratable acidity, respectively.
