CYTOGENETIC STUDIES ON REGENERATED PLANTS DERIVED FROM PROTOPLASTS OF ACTINIDIA DELICIOSA Ⅰ.VARIATION OF CHROMOSOME NUMBER OF SOMATIC CELLS

  • 摘要: 研究了美味猕猴桃叶愈伤组织原生质体再生植株和母株(Actinidia deliciosaline No.26)茎尖体细胞染色体数目。结果表明:母株2n=6x=174.所测29株再生植株的茎尖体细胞染色体数目差异显着,多为非整倍体类型,占所测植株的72.4%左右;体细胞染色体数目介于142-310条之间,其中2n=6x=174约占20.7%,少于174条染色体的植株约占31.0%,超过174条染色体的植株则占48.3%左右。个别单株部分茎尖体细胞在有丝分裂后期出现染色体桥、断片和落后染色体等异常现象。并对以上现象进行了扼要的讨论。

     

    Abstract: Chromosome number of stem tip cells of the pistillate plant,Actinidia deliciosa line No.26 and that of regenerated plants derived from protoplasts,which were isolated from leaf calli of the pistillate plant,were studied.It was indicated that the chromosome number of the pistillate plant was 2n=6x=174,and that of the 29 tested regenerated plant was variable obviously.Aneuploid occupied 72.4% of total regenerated plants tested.The chromosome number of most of the regenerated plants was between 142-310.Among them,plants with chromosome number of 2n=6x=174 were 20.7%,that of less than 174 were 31.0% and that of more than 174 were 48.3%.Some abnormal phenomena,such as chromosome bridges,fragments and lagging chromosomes appeared at anaphase of stem tip cells in a few plants.It was discussed about the phenomena mentioned above.
