【摘要】 以MS +NAA 1mg/L +KT 2mg/L为基本培养基 ,研究了不同浓度的 5种大量元素对银杏愈伤组织的细胞生长及其黄酮醇糖苷含量的影响。结果表明 :NH4 NO3和KH2 PO4 浓度与细胞生长率呈负相关 ;KNO3浓度对细胞生长率影响不大 ,但对黄酮醇糖苷含量影响明显 ;随着MgSO4 浓度的增加 ,细胞生长率和黄酮醇糖苷的含量呈现同步变化 ;随CaCl2 浓度的变化 ,细胞生长率和黄酮醇糖苷含量呈负相关。更多还原

【Abstract】 This paper reports the effects of five macronutrients on cell growth and synthesis in Vitra of Ginkgo flavonol glycosides.The treatments were designed based on MS agar media supplemented with 1mg/L NAA and 2 mg/L KT.The results showed that there was a negative correlation between the treatments concentration of NH 4NO 3 and KH 2PO 4 and the cell growth rate;The effects of KNO 3 treatments on the cell growth rate was not evident,whereas the effects on flavonol glycosides synthesis was significant.Both the cell growth rare and flavonol glycosides,content changed on the same trend with the increasing of MgSO 4 concentration;In the tests of different concentration of CaCl 2,cell growth rate was high,whereas flavonol glycosides content was low.更多还原
