【Abstract】 pon treatment with pectin degradate and Rhodotorula rubra homogenate as elicitors, the accumulation of indole alkolids in the suspension cultures of C. roseus crown gall cell was improved, but no change in the growth of crown gall cell was found. Elicitor dosage and the crown gall cell age can affect the alkaloids accumulation stimulated by the elicitors in cells. 5 to 10 days’ crown gall cells treated with 1% pectin degradate and 9 day’s crown gall cells treated with 5% Rhodotorula rubra homogenate exhibited maximum in alkaloids accumulation.更多还原
