| 摘 要： | 在大田栽培和自然光条件下，模拟紫外辐射增加对玉米生长发育、产量和品质的影响。分析结果表明，UV-B增加，导致株高变矮，叶面积降低，绿叶数、叶龄下降，干物重减少，发育期延迟，产量降低，玉米叶片类黄酮含量增加，叶绿素含量降低。这些变化具有随生育期不同而不同的特点。

| Abstract: | A field study was conducted to evaluate effects of enhanced UV-B radiation (ultraviolet radiation, broad band, 280-400nm) on development and yield of maize under field and natural sunlight conditions. It was concluded that the leaf area, the age of leaf, the leaf number, the height of stem, the content of chlorophyll in leaves and the yield will decrease, and the content of flavonoid in leaves of maize will increase, as the UV-B radiation enhances. |
