以大红红景天根、茎、叶为外植体,研究了影响愈伤组织诱导、芽增殖的主要因素。结果表明,叶片的诱导效果为最好,且叶片切块的最佳培养基为MS+6-BA 0.50 mg/L+IAA2.00 mg/L,诱导频率达85%。大红红景天叶片切块经诱导可产生3种类型的愈伤... 以大红红景天根、茎、叶为外植体,研究了影响愈伤组织诱导、芽增殖的主要因素。结果表明,叶片的诱导效果为最好,且叶片切块的最佳培养基为MS+6-BA 0.50 mg/L+IAA2.00 mg/L,诱导频率达85%。大红红景天叶片切块经诱导可产生3种类型的愈伤组织,其中只有紫红色的愈伤组织属于胚性愈伤组织易诱芽,分化培养基MS+6-BA 0.05 mg/L+IAA 0.50 mg/L有利于芽的分化和增殖。本研究建立了一套有效的以叶片为外植体的大红红景天的组织培养再生体系。 展开更多

The Rhodiola genus(Crassulaceae) is composed of about 90 species, mainly growing in high and cold regions. Some species are used as medicinal herbs to treat many diseases, such as cerebral hypoxia, cardiovascular disease, plateau response and so on. Up to now, about 180 constituents which are mainly glycosides, flavonoids, terpenoids, tannins, sterol and other compounds have been identified in the genus. The present review summarizes the chemical constituents isolated from the Rhodiola genus over the past few decades, with particular emphasis on Rhodiola crenulata(HK. f. et Thoms.) H. Ohba which is being studied by our research group. 展开更多
