The accumulation of sulphur and selenium containing compounds and their effects on glucosinolates in plant tissues of oilseed rape ( Brassica napus) was investigated. To study the effects of treatments on accumulation of glucosinolates in plant tissues, L methionine, selenate (SeO 2- 4 ) were used to replace sulphate (SO 2- 4 ) or increased SO 2- 4 supply in the nutrient solutions used in the culture of oilseed rape seedlings with sulphur (S) stress and sufficient. The results...
