'Huaibai', in order to provide a theoretical basis for field popularization and application of TAV-free ' Huai bai' plantlets. [ Method] With previously acquired TAV-free test-tube plantlets of ' Huaibai' as the experimental materials and its ordinary test-tube plantlets as the control (CK), chlorophyll content and some indexes related to nitrogen metabolism in leaves were determined during subculture. [ Result] During subculture, the contents of chlorophyll a and chlorophyll b in leaves of CK and TAV-free ' Huaibai' test-tube plantlets increased with the subculture days. Both realized the largest increase at the 22'h day of subculture, and their increase amplitudes were 5.24% and 41.69%, respectively. Compared with CK, the chlorophyll a and chlorophyll b contents of TAV-free test-tube plantlets increased at the same time point of subculture, with significant difference (P 〈0.05) or extremely significant difference (P 〈0.01 ). Further- more, the nitrate reductase (NR) activity, free proline and soluble protein contents of TAV-free ' Huaibai' were all significantly higher than those of CK, and the highest increase amplitudes were 27.99% ( subculture for 22 d), 28.10% ( subculture for 22 d) and 5.89% ( subculture for 38 d), respectively. [ Conclusion] TAV-free could effectively improve chlorophyll content and nitrogen metabolism level of ' Huaibai' , and was conducive to its growth and development.展开更多

Then, it studied agricultural intellectual property resources such as geographical indications, trademarks, patents, new plant varieties, biological genetic resources, and traditional knowledge related to C. morifolium . Finally, it summarized poverty-stricken areas ecologically suitable for planting C. morifolium , analyzed the GAP certification of C. morifolium , pollution-free agricultural product certification, green food certification, and organic food certification, and discussed the strategies for C. morifolium intellectual property protection and authenticity protection in the context of TCM development strategy and rural revitalization strategy.展开更多
