| 摘 要： | 以中国科学院海北高寒草甸生态系统定位研究站地区的美丽风毛菊为材料,通过短期增补UV-B辐射的模拟试验,研究了叶片光合色素和紫外吸收物质含量对增强UV-B的响应.不同处理天数的取样分析表明,与对照UV-A相比,增补UV-B＋UV-A处理时光合色素有增高的趋势,紫外吸收物质含量也略有增高.说明高山植物叶片中丰富的黄酮类物质能有效保护光合机构,短期内UV-B辐射强度的增加所加剧的色素光氧化现象并不严重,受叶片增厚的影响单位叶片面积的光合色素含量有增加趋势.

| Abstract: | The short-term field experiments of UV-B supplementation studying were conducted with alpine plant Saussurea superba in Haibei Alpine Meadow Ecosystem Research Station area.The photosynthetic pigments and UV-B absorbing compounds were measured after 5,10 and 15 days of treatment.The results indicated that compared with control UV-A treatment,there were an increasing of the photosynthetic pigments after enhancement of UV-B radiation(UV-B+UV-A) treatment,and UV-B absorbing compounds were also having small inc... |
