摘  要

   本实验以分葱(Allium ascalonicum Linn)幼苗为实验材料,采用不同剂量紫外光(0、2、4、6、8 h)照射分葱幼苗后,测定其可溶性糖含量、可溶性蛋白含量、叶绿素含量和总黄酮含量。结果表明:(1)照射剂量2、4、6、8 h后的分葱的可溶性糖含量与对照组差异不显著。(2)照射剂量4和8 h后的分葱可溶性蛋白含量显著低于对照组,而照射剂量2、6 h的分葱可溶性蛋白含量与对照组差异不显著。(3)照射剂量2、4、6、8 h后的分葱叶绿素含量显著低于对照组。(4)照射剂量6 h后的分葱总黄酮含量与显著高于对照组,而照射剂量2、4、8 h后的分葱总黄酮含量与对照组差异不显著。

ABSTRACT

   In this study, using Allium ascalonicum Linn as experimental materials, treat seeding by UV-radiation (90w) with different doses of 0, 2, 4, 6 and 8 hours, then determine the Soluble sugar content, Soluble proteins content, Chlorophyll content and the Flavonoid. The results showed the Soluble sugar content had no significant effect when UV-radiation dose of 2,4,6,8 h compare with contrast. The Soluble proteins content had significant effect when UV-radiation dose of 4 and 8 h compare with contrast, and The Soluble proteins content had no significant effect when UV-radiation dose of 2 and 6 h compare with contrast.The Chlorophyll content had significant effect when UV-radiation dose of 2,4,6,8 h compare with contrast. The Flavonoid had significant effect when UV-radiation dose of 6 h compare with contrast, and the Flavonoid had significant effect when UV-radiation dose of 2,4,8 h compare with contrast.
