ABSTRACT
In order to explore appropriate measures to promote germination after the harvest of Epimedium pseudowushanense, 6-BA, urea, ammonium bicarbonate and GA₃ were chosen to spray on the root and rhizomes, and then the biological indicators such as branches, leaf length, leaf width, plant height and so on, were measured in different periods, and the contents of epimedin A, epimedin B, epimedin C and icariin in the dry leaves were detected by HPLC. Results showed that 6-BA 90 mg·L⁻¹(B1), 6-BA 60 mg·L⁻¹(B2),6-BA 30 mg·L⁻¹+urea 300 mg·L⁻¹ (C1), 6-BA 60 mg·L⁻¹+urea 300 mg·L⁻¹(C2),6-BA 60 mg·L⁻¹+ ammonium bicarbonate 300 mg·L⁻¹(C4) significantly increased bud germination in the early period, and the plants quickly set up new system of photosynthesis, the branches in a month of which were higher than the control group respectively by 165.9%, 115.76%, 103.86%, 104.50%, 81.67%.However the branches developed the next year and the dry weight of leaves per plant in group B1 and B2 were much lower than that in control group. The groups that use 6-BA and nitrogen at the same time reaped a good yield of leaves even though the treatment had no significant influence on the branches developed the next year. The dry weight of leaves of C1, C2, C4 treatments were 36.80%, 32.84%, 45.97% more than the control group respectively. Therefore, C1, C2 and C4 treatments are the more appropriate to promote recovery after harvest. Furthermore, different groups, except 10 mg·L⁻¹ 6-BA treatment significantly reduced the content of epimedin C, other groups didn't have any significant effect on the contents of such flavonoids.
