- Abstract
Objective: To study the influence of different factors (temperature, light and germinating beds) on seed germination of Codonopsis tangshen., Method: The general germination method was applied., Result and Conclusion: The optimum seed germination conditions of C. tangshen were as follows: temperature 25 degrees C, light, germinating-beds top of paper (TP) or between of paper (BP). The first seedling--counting time was the 10th day after beginning the test; the final time was the 18th day. The test also showed that gibberellin notably increased the seed germination rate of C. tangshen.
