| 摘 要： | [Objective] The aim of this study was to investigate the chromosome number and the karyotype of Scilla scilloides in Yantai.[Method]Root tips of Scilla scilloides were pretreated by 8-hydroxyquinoline,then fixed,dissociated and stained for slice production.The chromosome number was analyzed by microscopic examination,and then cells with good chromosomal morphology and dispersal chromosome were studied by microscopic photos.[Result]The somatic chromosome number of Scilla scilloides in Yantai was 2n=16+1Bs,while the karyotype formula was K(2n)=2x=16+1Bs=6m+4sm(2SAT)+4st+2t+1Bs and the karyotype classification was "3B" type.[Conclusion]Karyotype comparison,division of cell type and evolution of Scilla scilloides in Yantai are discussed,which provides basis for cytogenetics,evolutionary genetics,modern taxonomy and genetic breeding.1

| Abstract: | [Objective] The aim of this study was to investigate the chromoseome number and the karyotype of Scilla scilloides in Yantai. [Method] Root tips of Scilla scilloides were pretreated by 8-hydroxyquinoline, then fixed, dissociated and stained for slice production. The chromosome number was ana-lyzed by microscopic examination, and then cells with good chromosomal morphology and dispersal chromosome were studied by microscopic photos. [Re-sult] The somatic chromosome number of Scilla scilloides in Yantai was 2n=16+1Bs, while the karyotype formula was K (2n)=2x=16+1Bs=6m+4sm (2SAT)+4st+2t+1Bs and the karyotype classification was "3B" type. [Conclusion] Karyotype comparison, division of cell type and evolution of Scilla scilloides in Yantai are discussed, which provides basis for cytogenetics, evolutionary genetics, modem taxonomy and genetic breeding. |
