丹参组织培养材料的染色体显微鉴定技术

Technique of Chromosome Microscopic Determination in Cultured Material of Salvia miltorrhiza

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,国内外还未见报

Abstract: 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 pretr
