| Abstract: | The study was used to overally reveal pollen morphology and phenotypic characteristics of chromosome karyotype,pollen morphology,leaf epidermal pollen morphology and phenotypic characteristics from Christolea crassifolia Camb.in thee populations of Pamirs plateau region by use of the principle and method of population.Our results showed that in the three populations,chromosomes(2n) were 14,i.e.radix was seven.The dissymmetrical coefficients of karyotypes were 1A type.Three germinating holes were distributed... |
