摘　　要：应用图象自动分析和识别的原理，建立了植物染色体自动分析ＣＨＲＯＭ．ＨＵＫ软件系统，并对西藏野生大麦和巨柏进行了核型计算机自动分析。染色体自动分析主要功能特点有染色体图象处理，染色体自动分析主要功能特点有染色体图象处理，染色体峰谷阈值的确定，染色体中心线的求得，重叠染色体的分离，着丝点和次缢痕位置的极限腐蚀判别，染色体特征参数的提取和核分析。获得的大量数据补存贮，运算和统计分析。A plant chromosome image analysis CHROM. HUK software system has been developed in the light of the theory of image analysis and recognition and applied in kary-otype automated analysis of Xizang wild barley (Hordeum agriocrithon Aberg var. ni- grum) and Cupressus gigantea Cheng et L. K. Fu. The main features of automated analysis include the pre-processing of chromosome image, determinating peak-valley threshold of chromosome, separation of overlapping chromosome, evaluation of centre line of chromosome,limit erotion recognition of position of centromere and second con-(?)trie, extraction of characterictic parameters of chromosome and karyotype analysis. The vast amount of data obtained could be stored, operated and used for further statistical analysis. According to the estimation in the 95% confidence interval and the rree type sort, the chromosome were paired and sorted. In the meantime, a karyogram and an id-iogram of karyotype were generated automatically through computer ization.
