| 摘 要： | 本文对金花茶(Camellia chrysantha (Hu) Tuyama)组培苗的染色体核型进行了研究。结果表明:金花茶组培苗不仅染色体数目与其野生种相同,2n=30,而且核型也基本一致,核型公式均为2n=2x=30=22m+8sm(2SAT)。这些数据为利用组织培养方法保存和繁殖金花茶的可行性提供了细胞学方面的依据。

| Abstract: | In this paper, the karyotype of Camellia chrysantha (Hu) Tuyama and it's regenerated plant were studied. The results show that they are the same in chromosome number and also in karyotype. The somatic chromosome in shoot-tip cell is found to be 2n=30, among these 11 pairs had median constrictions, 4 pairs had submedian centromere, and the nth pairs was SAT-chromosome. According to terminology defined by Leven et al., the karyotype formulae are 2n=2x=30=22m+8sm(2SAT). The cytological information obtained through present study provided basis for conservation of C. chrysantha (Hu) Tuyama by using plant tissue culture. |
