Abstract：【Objective】The effects ofdiferent treatments onthefruitquality and yieldoffragrant pear were analyzed by treating the single plant of 10- year-old dense planting trunk-shaped fragrant pear with different loads，and the optimum single plantload wasobtainedbycomprehensiveevaluation，whichprovidedareferenceforthe high-qualityandeficientproductionof fragrant pear. 【Methods】Five treatments （60，100，140，180 and 22O）were carried out on a 10- year-old densely planted trunk-shapedfragrantpearbyartificialfruit thinning，andtheefectsofdiferentloadevelsonthefruitqualityandyieldoffragrant pear were analyzed.【Results】The comprehensive evaluation of140 treatments with fruit bearing capacity per plant （0.90 0）was the best，followedby100 treatments（0.6708），60treatments （0.5801）and180treatments（0.5777）were average，and 220treatments （O.493 8）were the worst.【Conclusion】Theoptimum load per plant of densely planted trunk Korla fragrantpear in full fruit stage isloo—14O fruits.
