英文摘要 | a cytogenetic study was conducted on rheum tanguticum populations from huangnan tibetan autonomous prefecture, china. the results revealed the chromosome numbers 2n=22 and the karyotype formulae are 2n=22=22m or 2n=22=2sm+20m, belonging to stebbins 1a type. however, it was interesting to observe metaphases with variable b chromosomes (1, 2, 3, 4, 6, 7) in a few specimens. for the first time, the occurrence of b chromosomes was reported in natural populations of r. tanguticum. the number of b chromosomes in r. tanguticum varied not only among individuals but also within the same root tip. |
