文摘内容 The factors influencing pollen chromosome doubling in Zenjimaru persimmon were studied,based on the knowledge of meiosis of pollen mother cells.The results showed:(1)the suitable concen-tration of colchicine was 0.3-0.5%;(2)the best doubling effect could be obtained during the period from the diplotene stage to the diakinasis stage,and the highest proportion was up to 40.6%;(3)considering giant pollen ratio and proportion of staminate-flower collection,the better treating frequency was 3 times;(4)giant pollen,which formed mainly form dyad and had bigger cell nucleus volume,was unreduced and hexaploid。
