摘要:
以M1代变异株（四倍体）金银花与对照株（二倍体）金银花的根尖为试材，分别对M1代变异株和对照株进行细胞学鉴定。结果表明：对照株金银花的核型为K=2n=2x=18=8m+8sm+2st;M1代变异株金银花的核型为K=2n=4x=36=16m+16sm+4st。M1代变异株的染色体数目增加1倍，证明为多倍体。
Abstract:
Using root tip of diploid and tetraploid Lonicera japonica Thunb M1 as test matericals,karyotypic analysis of diploid and tetraploid Lonicera japonica Thunb were studied.The results showed that diploid Lonicera japonica Thunb：K=2n＝2x=18=8m+8sm+2st;tetraploid Lonicera japonica Thunb：K=2n=4x=36=16m+16sm+4st.The chromosome number of the mutant was doubled and proved to be polyploidy.
