摘要
染色体是遗传基因的主要载体。生物的遗传、变异、繁殖和发育都与染色体的结构和行为有密切联系。染色体的倍数性变化是导致植物发生遗传变异的主要途径,这也为育种工作者创造选择优良品种的机会。有关丹参的染色体显微鉴定技术。
The method in chromosome determination of cultured material of Salvia miltorrhiza Bag. ssp was studied in order to obtain good separation of chromosome for microscopic determination. A series of experiments, such as the time of cutting material, the pretreatment method and the hydrolytic method were conducted. Based on the results of experiments, a good method was developed. By using the method, polyphoids were obtained by chromosome microscopic determination of Salvia miltorrhiza plantlets induced artificially.
