摘要(Abstract):

[Objective] To evaluate and screen the high-quality germplasm resources of HERBA TAXILLI. [Methods] A total of 21 germplasms were collected in Guangxi Zhuang Autonomous Region of China in 2008- 2010. they were all introduced into germplasm nursery of Qinzhou City. The growth status,yield,stress resistance and other indexes were recorded. Content of total flavonoids was detected by aluminium trichloride colorimetric method. Quercetin content was extracted by methanol-hydrochloric acid( 4∶ 1) and detected by RP-HPLC. [Results] The results of character analysis of 21 varieties were integrated; and the 21 germplasms of HERBA TAXILLI were comprehensively evaluated. With the growth status,yield,stress resistance and total flavonoids content as the indexes,the high-quality germplasm of HERBA TAXILLI was screened. The standards for high-quality germplasm were as follows: gradeⅠ for growth status,130 g yield per plant,95% survival rate,24. 0 mg / g total flavonoids content and 4. 0 mg / g quercetin content. [Conclusions] Based on the comprehensive evaluation of indexes,three high-quality germplasms of HERBA TAXILLI were screened,which were from Qinzhou City,Nanning City and Yulin City. The original host plants were Averrhoa carambola,Nerium oleander and Dimocarpus longan. And the fruits were all oval and tuberculate.
