摘要

目的:对射干鸢尾染色体数目、形态等进行研究,为该种鉴定、演化和良种选育等提供必要的细胞学资料。方法:采用常规制片方法,结合显微摄影对染色体进行检测分析。结果:染色体数目为2n=40。核型公式为K(2n)=40=30m+6sm+2st(2SAT)+2T,染色体相对长度组成为2n=40=2L+14M2+22M1+2S,属于2A型。全组染色体总长74.16μm,长臂总长4492μm,核型不对称系数60.57%?染色体组总体积153.17μm3。结论:射干鸢尾染色体数目、形态清晰,可为进一步的深入研究打下基础。

Abstract

OBJECTIVE:To study the evolution and fine seeds selection through Iris dichotoma chromosome number,karyotype and volume.METHODS: Sections combined with micrograph were used to analyse chromosome karyotype etc.RESULTS: Chromosome number is 2n=40. K (2n)=40=30m+6sm+2st(2SAT)+2T. The species chromosome based on the relative length was 2n=40=2L+14M2+22M1+2S,which belong to“2A”type according to the Stebbings karyotype classification. The total length of chromosome groups was 74.16μm,the total length of long arms was 44.93μm,and the AS·K% was 60.57%.The total volume of chromosome groups was 153. 17μm3 according to De-vescovi et al.CONCLUSION: Iris dichotoma chromosome number,morphological character became clear.
