Pollination Biology Characteristics of Prunus salicina Lindl.cv. ‘Kongxinli'

ZHANG Yi;ZHANG Hui;WANG Fengwei;HU Huan;CHENG Lei;College of Gardening and Horticulture,Yangtze University;Jianshi Qili Fruit Industry Co.Ltd.;  
Prunus salicina Lindl.cv.‘Kongxinli'and its pollinated varieties were used as materials.The flowering phonological period,quantityes and viabilities of pollen,stigma receptivity and the selfpollination and cross-pollination compatibilityes of Prunus salicina Lindl.cv.‘Kongxinli'were studied in order to provide reference for the high-yield cultivation techniques of Prunus salicina Lindl.cv.‘Kongxinli'.The results showed that the flowering period of Prunus salicina Lindl.cv.‘Gulf-ruby'and Prunus domestica L.cv.‘Yellow champagne'were consistent with that of Prunus salicina Lindl.cv.‘Kongxinli'.The variation range of pollen quantity among all varieties was 300-733 grains per anther,the order from high to low among all varieties was Prunus cerasifera Ehrh.cv.Atropurpurea Jacq.,Prunus salicina Lindl.cv.‘Hongxinli',Prunus domestica L.cv.‘Yellow champagne',Prunus salicina Lindl.cv.‘Kongxinli'and Prunus salicina Lindl.cv.‘Gulf-ruby',and their pollen germination rate were 21.9%,47.2%,17.4%,13.5% and 24.6%,their fruit setting rates after pollinating Prunus salicina Lindl.cv.‘Kongxinli'were 7.41%,7.27%,10.34%,12.59% and16.18%,respectively.The fruit setting rates of natural pollination of Prunus salicina Lindl.cv.‘Kongxinli'was 6.00%.The stigma receptivity could stay 7 days from the day before flowering to the fifth day after flowering,and ones were the strongest in the day before flowering,flowering day and the day after flowering.On the whole,Prunus salicina Lindl.cv.‘Kongxinli'showed lower pollen viability,moderate pollen quantity,5 days stigma receptivity after flowering,agood self-pollination compatibility.Although the pollen quantity of Prunus salicina Lindl.cv.‘Gulf-ruby'was low,the pollen viability was higher,the flowering period was consistent with and showed a good pollination compatibility with and could be used as a pollinated variety of Prunus salicina Lindl.cv.‘Kongxinli'.
