Chromosomal studies on populations of Aquilaria sinensis
摘要
Abstract
For the first time,a conventional analysis of chromosome karyotype and Giemsa C-banding was carried out in three populations of Aquilaria sinensis. Three populations showed same chromosome number of 2n=2x=16 and the asymmetry of the karyotype was categorized as type 2B. The variance of karyotype was not obvious in three populations,only karyotypical formula (2n=16=4m+8sm+4st) in one population was different from the other two (2n=16=6m+6sm+4st). The Giemsa C-banding pattern of A.sinensis was CIT pattern. Within Giemsa C-banding pattern of A.sinensis there were centromeric bands,intercalary bands,telomeric bands and whole bands. The distributed position,numbers and types of the C-banding on the chromosome of A.sinensis had shown the clear polymorphisms.关键词
