Abstract：For studying the pollen xenia of plum,pollens of 5 different plum cultuvars including Bulin, Longyuanqiuli, Oishi Wase,Japanese plum and Changli 15 were used to pollinate Frinar plum respectively,and the effect in the current year on fruit quality was observed.A series of index were detected for each single cultivar pollinated fruit and the open pollinated fruit.The fruit setting rate ranged from 15.7% to 60.0% depending on the pollinators, while for the open pollination was 36.0%; the fruit weight ranged from 71.6 g to 79.7g and 73.0 g; length and width of fruit were 4.4/5.2 cm,4.3/5.2 cm,4.1/4.9 em,4.5/5.4 cm, 4.0/5.0 cm and 4.2/4.9 cm respectively; the soluble solids content were 11.7% to 12.7% and 11.6%; titrat-able acidity were 0.79% to 0.80% and 0.79%, and the fruit apex shape was obviously different pollinated by different cuhi-vars.Based on the Duncan's multiple range test,there was obvious difference in all above mentioned fruit quality index a-mong the fruit received from different pollinators,indicating the distinct pollen xenia for plum.This paper is useful to support the further study and rational allocation of pollination cultivars in practice so as to improve the fruit quality and benefits.
