Abstract Adopting field test method and taking broccoli cultivar‘ Naihanyouxiu’ as test material,this paper studied the effects of foliar spraying 2 selenium fertilizers with different concentrations on the contents of glucosinolate and selenium in broccoli.Among of them,the concentrations of selenium fertilizer‘Fuxibao’were set to 12.0,9.6,8.0,6.9,6.0,0(CK)mg · L-1,concentrations of the other fertilizer ‘Highconcentrated Organic-selenium Fertilizer’ were set to 2.5,2.3,2.1,1.9,1.8,0(CK)mg · L-1.The results showed that the total glucosinolate contents of broccoli treated with 6.0 mg · L-1 ‘ Fuxibao’ and 2.3 mg ·L-1 ‘ High-concentrated Organic-selenium Fertilizer’ were the highest,being 13.72 and 15.38 μmol · g-1,respectively,increased by 5.86% and 18.67% comparing with their corresponding controls.The differences had all reached a significant level.Treatments of 9.6 mg · L-1 ‘ Fuxibao’and 2.3 mg · L-1 ‘ High-concentrated Organic-selenium Fertilizer’ had obtained the highest selenium contents in broccoli,being 0.811 3 and 1.776 7 mg · kg-1,respectively,reaching 3.52 and 7.74 times of their corresponding controls,respectively.The differences were also reaching a significant level,indicating both selenium fertilizers could effectively increase the glucosinolate contents and selenium contents in broccoli.Meanwhile,the total glucosinolate contents and beneficial glucosinolate(RAA,4OH,GBC,4ME,NEO)contents of broccoli treated with 2.3 mg · L-1 ‘High-concentrated Organic-selenium Fertilizer’ were higher than that treated with 6.0 mg · L-1 ‘ Fuxibao’,
indicating 2.3 mg · L-1 ‘High-concentrated Organic-selenium Fertilizer’had better effects on improving.
