摘要: 本文以日本大葱为材料,以荧光灯照射为对照,研究了 UV辐射增强对大葱株高、茎粗、含水量、类黄酮、叶绿素、V c、可溶性糖含量等形态和生理指标的影响。 结果表明:UV辐射增强条件下供试大葱株高显著降低,而茎粗无显著变化;类黄酮含量显著升高;而叶绿素 b 含量显著降低;叶绿素a、叶黄素、含水量、V c 、可溶性糖含量无显著变化。

Abstract: In this study,the effects of UV-B radiation on plant height, stem diameter, water content, contents of flavonoid , chlorophyll , V c and soluble solid of welsh onion (Allium fistulosum L.) were studied. The results were as followings: plant height, the content of chlorophyll b and flavonoid content were significantly affected by enhanced UV-B radiation. However, contents of chlorophyll a and total chlorophyll, water, V c, and soluble solid were not significantly affected.
