棉属不同种的分类,早年是以形态特征进行划分的,近代则以细胞学、地理生态分布及其可交配程度三者相结合为依据。同工酶技术的发展,迅速被利用在研究植物不同种属间亲缘关系及起源上。B.L.Johnson and M.M.Thein(1970)用蛋白质电泳法对棉花系统发育中的亲缘关系进行过研究,从而补充了棉属进化的理论;吴小月(1983)曾对四个栽培棉种的酯酶和过氧化物同工酶作过分析;孙传渭等(1989)和钱思颖(1985)系统分析比较了棉属不同种及品种的种子酯酶同工酶。1987年,我们开展了种子酯酶同工酶的分析工作,其目的想从酶的角度探讨棉属种的关系。
Gossypium is a species of different species, the early is divided by the morphological characteristics, the modern time based on cytology, geographical and ecological distribution and the degree of mating can be based on the combination of the three. The development of isoenzyme technology is rapidly being used to study the genetic relationship and origin of different species in plants. BL Johnson and MM Thein (1970) studied the phylogenetic relationship of cotton system by protein electrophoresis, which supplemented the theory of cotton evolution. Wu et al. (1983) studied the esterase and peroxidation of four cultivated cotton species Isozyme analysis; isozyme of the seeds of different genus and varieties of cotton genus were systematically analyzed and compared by Sun Chuanwei et al. (1989) and Qian Siying (1985). In 1987, we carried out the analysis of the seed esterase isozymes, the purpose of which is to explore the relationship between cotton species from the perspective of enzymes.
