| Abstract: | In this study, the effects of enhanced 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 showed that under the enhanced UV-B radiation, plant height decreased significantly, while the stem diameter was not significantly affected;the content of chlorophyll b decreased significantly, however the flavonoid content increased significantly compared with the CK.It was also noticeable that contents of chlorophyll a and total chlorophyll, water, V c, and soluble solid were not significantly affected by the enhanced UV radiation.These results would be useful for breeding out new cultivars of welsh onion with high flavonoid content. |
