甜瓜（Cucumis梅洛L.）比较了体细胞胚、不定芽、芽原基和腋芽再生植株的再生率。体细胞胚、不定芽和茎原基诱导的再生植株中均存在四倍体，三种培养方法的四倍体频率分别为31%、30%和4%。从腋芽繁殖的植株中没有观察到四倍体。四倍体的出现是甜瓜组织培养中普遍存在的现象。
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.
