Intraspecific Differences in Growth, Physiology,and Flavonoid Yield of Six Erigeron Breviscapus Populations from Different Altitudes to Enhanced UV-B Radiation

摘要：

　　The effects of enhanced UV-B radiation (280-315 nm) on the growth,physiology and flavonoid yield of six Erigeron breviscapus populations were studied through simulation experiment under greenhouse conditions.Seeds from four higher altitude populations (Xiaohe,Cangshan,Xueshan and Napa from altitude 2100 m-3280 m) and two lower altitude populations (Huguo and Xijiang from altitude 900 m) of wild E.breviscapus were sown in a greenhouse.
