Analysis of chromosome karotype in Choerospondias axillaris
In order to provide cytological basis for breeding of Choerospondias axillaris,the chromosomes was determined and analyzed by common squash method and microphotography.The results indicated that the number of the somatic chromosome in Ch.axillariswas 2n=24,and its karyotype formula was K(2n)=2x=24=22m+2sm;the constitution of relative length of chromosome was 2L+10M2+8M1+4S;the asymmetry index was 55.77%.The chromosomes of Ch.axillaris was diploid,and was mainly metacentric and submetacentric.Based on the Stebbins'classic method,the karyotype of Ch.axillaris belongs to"1B"type.
