摘要： Gnetum parvifolium is one of important economic plants used as traditional medicine, and little is known about the flavonoid production in G. parvifolium in response to stress. The content of flavonoid in different tissues of G parvifolium when exposed to treatments of high-temperature (40 degrees C) and ultraviolet-C was investigated. The total flavonoid content of leaves, stems and roots reached 149.1, 53.9 and 52.79 mg/g DW, respectively. The concentrations of flavonoid in different tissues significantly decreased under the high-temperature condition. In contrast, the ultraviolet-C treatment had no significant impacts on the total flavonoid concentration in leaves while the content initially decreased and then increased in stems and roots under the treatment of ultraviolet-C. The present results showed that leaves of young seedlings were rich in flavonoids. The treatment of high temperature and ultraviolet-C did not significantly promote the accumulation of total flavonoids. The present study would help to understand how Gnetum gets adapted to tropical and subtropical biomes and habitats for the perspective of plant evolution. Besides, it can be beneficial for breeding flavonoids-rich gymnospermous plants for the purpose of industrial usages.
