Ti转化的丹参组培物在MS-NH4培养基(MS中不含硝酸铵，含蔗糖 30 g*L－1)上经25 ℃暗培养18 d，生长量由大到小依次为：对照(CK)，200 μmol *L－1水杨酸(SA)，4 g*L－1酵母激发子(E)和E+SA处理。其中CK和SA处理的组培物仅产生痕量的丹参酮类物质，而E和E+SA处理的总丹参酮产量分别增加到12.23 mg* L－1和15.07 mg*L－1，表明E处理能促进组培物产生丹参酮类物质，而SA可以强化E的这种作用。与上述差异有关的内源激素变化是：培养6～18 d，E+SA处理的ABA和i PAs含量均持续高于对照，分别增长了2.8～9.8倍和3.6～5.8倍，而GA1+3和IAA 含量分别比对照降低13.2%～56.9%和34.8%～74.6%。高水平的ABA和iPAs及低水平GA 1+3和IAA抑制了组培物的生长，有利于促进丹参酮产量的提高。“,”The fresh weight and dry weight of Ti-transformed Salvia miltiorrhiza cell aggregates increase differently with various treatm ents,after being cultured in the MS-NH4 medium(MS without ammonium nitrate,co ntaining 30 g*L－1 sucrose)under darkness for 18 days(25 ℃).The total tanshinones production reaches 12.23 mg*L－1 and 15.07 mg*L－1 by exogenous application of 4 g*L－1 of yeast elicitors(E)and E+200 μmol*L－1 of salicylic acid(SA)respectiv ely.Howeve r,only trace amount of tanshinones was detected in the control and SA treatment, indicating that E could promote tanshinones production and SA enhances the effect of E.Compared with the control,the contents of ABA and iPAs in E+SA treated cell aggregates rise continuously and with an increase of 2.8-9.8 and 3.6-5. 8 fold respectively,but those of GA1+3 and IAA are decreased by 13.2%-56 .9% and 34.8%-74.6% respectively,suggesting that high level of ABA and iPAs combined with low level of GA1+3 and IAA inhibits the growth of cell aggre gates,and therefore significantly stimulates the tanshinones production.
