摘要：In the southeast of the Qinghai-Tibetan Plateau of China, a buckthorn ( Hippophae rhamnoides L.), which is a thorny nitrogen-fixing deciduously perennial shrub, has been widely ud in forest restoration as the pioneer species. In our study, two contrasting populations from the low and hig
h altitudinal regions were employed to investigate the effects of drought, ultraviolet-B (UV-B) and their combination on a buckthorn. The experimental design included two watering regimes (well watered and drought stresd) and two levels of UV-B (with and without UV-B supplementation). Drought significantly decread total biomass,
