本文用染色体图象分析系统对大麦N带染色体进行分析,同时用传统的人工方法分析,并将二者进行比较。结果表明:染色体图象分析系统可以消除在显微摄影、照像、测量等过程中造成的误差,还可以消除不同研究者之间人工判断的差异,能够更客观、准确、迅速地得到染色体带型模式图,这些都是人工方法所不及的。染色体图象分析系统还将在植物染色体高分辨显带染色体的分析中起重要作用。 In this paper, the chromosomal image analysis system was used to analyze the chromosomes of N band in barley, meanwhile the traditional manual methods were used to analyze the two. The results show that the chromosome image analysis system can eliminate errors caused by microscopic photography, photography, measurement and so on, and can also eliminate the discrepancy of human judgment among different researchers, and can obtain chromosome bands more objectively, accurately and rapidly Type map, these are artificial methods beyond. Chromosome image analysis systems will also play an important role in the analysis of high-resolution chromosomes in plant chromosomes.
