Responses of Common Buckwheat(Fagopyrum Esculentum)to Enhanced UV-B Radiation and Selenium

摘要：

The impact of UV-B radiation and seleniam treatment on common buckwheat was studied in the outdoor experiments. The respiratory potential．plant height and biomass were measured in UV-B and selenium treated buckwheat plants．Plants were exposed to three levels of UV-B radiation;reduced level of UV-B radiation, ambient, and enhanced UV-B radiation, corresponding to a 17%reduction of stratospheric ozone layer．Selenium was applied as a foliar spray of sodium selenate at the time of blossoming．UV-B radiation induced the synthesis of UV absorbing compounds．Se treatment counteracted the stunting eflfect and lowering of biomass in UV-B treated common buckwheat plants．
