Study on Pollen Chromosome Doubling in Zenjimaru Persimmon
摘要
The factors influencing pollen chromosome doubling in Zenjimaru persimmon were studied,based on the knowledge of meiosis process 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 fromthe dipiotene stage to the diakinasis stage, and the highest proportion was up to 40.6 %; (3) considering giantpollen ratio and proportion of staminate-flower collection, the better treating frequency was 3 times; (4) giantpollen, which formed mainly from dyad and had bigger cell nucleus volume, was unreduced and hexaploid.
