The meiotic process of microspore mother cell of Calycanthus chinensis is investigated for the first time, and the fertility of pollen grain is observed.Although in anaphase Ⅰ, telophase Ⅰ and anaphase Ⅱthere are some abnormal chromosome behaviors occurred, the whole process is basically normal.The fertility of most pollen grains is normal also.Human disturbance may be the main factor causing the rare and endangered position and narrow distribution situation of C.chinensis.
