Abstract
[Objective] The purpose was to study effects of selenium on physiological and biochemical characteristics of flue-cured tobacco,to provide scientific basis for good quality and high yield production.[Method] The effects of applying selenium selenite in different times on vitality of flue-cured tobacco roots,activities of the key enzyme,the contents of membrane lipid peroxidation product malondialdehyde(MDA) and chlorophyll,the other physiological and biochemical indices were analyzed through a field test.[Result] The results showed that 0-30 mg/L selenium could improve flue-cured tobacco roots activity and its leaves protective enzyme activities,chlorophyll content and photosynthetic efficiency,while MDA content decreased with the increasing concentration of selenium.[Conclusion] Applying selenium fertilizer in lower content selenium soil can improve flue-cured tobacco quality.
