Abstract:

The aim is to assess the effect of exogenous Se fertilizer on yield and nutritional status of Chinese flowering cabbage (Brassica campestris ssp. chinensis var. utilis). In this study, “Nongke” selenium enriched fertilizer was used as the material, and five different doses (0, 225.0, 337.5, 450.0, 562.5 kg/hm2) were supplied via basal fertilization. The results showed that the selenium enriched fertilizer addition did not markedly improve the plant growth parameters at all test concentrations. The activities of SOD, POD and CAT and the contents of fructose increased significantly in a dose dependent manner in “Nongke” treated plants compared to that of non-treated, however, the contents of MDA, glucose and sucrose showed a decreasing trend with the increase of fertilizer amount. The up-take of nitrogen, phosphorus and potassium by Chinese flowering cabbage plants were promoted by basal application of lower concentrations of selenium enriched fertilizer, but was inhibited by higher fertilizer amount. With the increase of the amount of selenium fertilizer, the selenium content increased significantly in the flower stalk of Chinese flowering cabbage, reaching 0.059, 0.096, 0.107, 0.133 mg/kg, respectively, 19.66-44.33 times of that of the control plant.

Key words: Chinese flowering cabbage, selenium enriched fertilizer, basal fertilizer, enzyme activity, nutrient element
