摘要：

The frequency of tetraploidy in melon plants (Cucumis melo L.) regenerated from somatic embryos, adventitious shoots, shoot primordia and in plants propagated from axillary buds was compared. Tetraploids were found in plants regenerated from somatic embryos, adventitious shoots and shoot primordia, and the frequency of tetraploids in the three culture methods was 31%, 30% and 4%, respectively. No tetraploidy was observed in plants propagated from axillary buds. The highly frequent appearance of tetraploidy in regenerated plants appears to be a universal phenomenon in tissue culture of melon.
