植物核型分析方法的研究进展(英文)

Progress of Karyotype Analysis Method in Plants Research

植物核型分析方法是植物系统学等学科的一门基本技术.本文将植物核型分析方法的发展过程划分为两个阶段:染色体形态标志分析时期和分带分析时期,并分别阐述了这两个时期在核型分析方法上的创新,以及这些方法的优点和不足之处.同时对其今后的发展方向作一展望.分析了限制植物核型分析方法发展的几个因素,认为核型分析方法要取得突破性进展,第一必须扩大其应用范围,提出新的研究课题,第二必须结合动物和人体核型分析的最新研究方法以及其它学科的实验技术和理论方法.

Karyotype analysis method of plants is a basic technique in taxonomy and other related subjects. Its research progress stages are divided into two parts: chromosome morphological mark analysis and banding analysis. The methods in these two stages are elaborated respectively. Its prospects are also discussed. We have analysed the factors restricting the progress of karyotype analysis methods in plant. Karyotype analysis method in plants will not breakthrought until its application range is expanded and new research projects is brought up with and combinaed with other experimental techniques and theory methods in other subjects.
