Abstract:: The corresponding relationship of pollen development period and the flower external morphology and the ratio changes of different development degree pollen in development periods were studied.The results indicated that pollen development period and flower morphology had correlation，when the bud was compact and length was 7～9 mm，area ratio of calyx and leaf were about 1∶2，calyx attached petals or 1 calyx spread out，1～2 outer petals were slightly cracked and inward parcel，the ratio of total mononuclear mid anaphase and terminal stage pollen were 74.6%～87.1%,the anthers were wrapped by petals and easy to be handled，was the suitable sampling period of pollen.
