摘  要:
采用常规压片法对巴西橡胶树高产品种热研88-13和热研8-79的染色体数目和核型进行了研究。结果表明,热研88-13与热研8-79的体细胞染色体数目均为2n=36,热研88-13的核型公式为2n=2x=36=28m+8sm(4 SAT),热研8-79的核型公式为2n=2x=36=28m+8sm(2 SAT),二者均属于Stebbins型的2B型。

摘  要:
The numbers and karyotypes of chromosomes of Hevea brasilienais clones Reyan 88-13 and Reyan 8-79 were studied,applying fingertip pressing flake method.The results showed that the chromosome number of each of the two clones was 2n = 36,Reyan 88-13 karyotype formula was 2n = 2x = 36 = 28 m + 8 sm(4 SAT),and Reyan 8-79 was 2n = 2x = 36 = 28 m + 8 sm(2 SAT),and both belonged to Stebbins 2B type.
