摘  要

　　　本實驗以分蔥(Allium ascalonicum Linn)幼苗為實驗材料，采用不同劑量紫外光（0、2、4、6、8 h）照射分蔥幼苗后，測定其可溶性糖含量、可溶性蛋白含量、葉綠素含量和總黃酮含量。結果表明：（1）照射劑量2、4、6、8 h后的分蔥的可溶性糖含量與對照組差異不顯著。（2）照射劑量4和8 h后的分蔥可溶性蛋白含量顯著低于對照組，而照射劑量2、6 h的分蔥可溶性蛋白含量與對照組差異不顯著。（3）照射劑量2、4、6、8 h后的分蔥葉綠素含量顯著低于對照組。（4）照射劑量6 h后的分蔥總黃酮含量與顯著高于對照組，而照射劑量2、4、8 h后的分蔥總黃酮含量與對照組差異不顯著。

關鍵詞：分蔥；紫外；可溶性蛋白；可溶性糖；葉綠素；總黃酮

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.
