摘　　要：对引种的泡泡树4个品种果实单果重、纵径、横径、果形指数及生长动态进行了初步研究,结果表明不同品种间单株结果量存在较大差异。根据当前单株结果量和果实性状表现,筛选出M ary Foos Johnson和Overleese两个早期丰产的优良品种;同时发现各品种之间果实横径和纵径大小存在差异。4个泡泡树品种的纵横径变化在泡泡果实成熟前期都随着时间的增加而增大。The fruit growth dynamics of four pawpaw varieties including ＇ Seed Seeding＇ , ＇ Overleese＇ , ＇ Taylor＇ , and ＇ Mary Foos Johnson＇ , was studied by examining the longitudinal diameter, the transverse diameter, and the fruit form. The results showed that there were the significant differences in individual fruits between the varieties of pawpaw. Two fine high- yield varieties, Mary Foos Johnson and Overleese, were selected based on the fruit characteristics and yields. It was also found that there were differences in transverse diameter and longitudinal diameter between the varieties of pawpaw. The transverse and longitudinal diameter of the four varieties were increased with the time before ripening of pawpaw fruit.
