Research on the relationship between nursery technique and survival rate of transplanted seedlings of Radix Puerariae

This study aimed to investigate the relationship between survival rate of seedling and different nursery techniques in Radia Puerariae.The results showed that germination rates of QS08-1 and Gange 1 was up to 90%，there was no difference in the same position of branch germination rate of elder branches was up to 88%， which was 50% higher than adult branch，and 70% higher than young branch. There was no difference on germination rate treatmented by gibberellin，indole acetic acid，naphthalene acetic acid，but there was a significant difference between treatment and control. The survival rate of transplanted seedling was 97.33%，the survival rate of elder branches cottage seedling was 77%，46.44 %higher than that of the layering seedling，and the survival rate of adult branches cottage seedling was 41.67 %，11.11 %higher than that of the layering seedling，and 2.78% of young branch currage seedlings，27.78% lower than the control. The seedling emergence rate of different cultivars was more than 98%，the survival rate of transplanted seedling was only 30.56%.Our results indicate that the seedling rate of Radix Puerariae and the cuttage seedling of elder branch was high，with higher survival rate transplanted seedling.
