Abstract

Several studies focused towards improving the quality of nutritional plants, due to limited microelements and macroelements in various agricultural areas. Micronutrient elements as selenium are beneficial for human health at small quantities, but when taken in large quantities lead to toxicity. It seems that, plants that are rich in sulphur compounds such as cabbage and broccoli (brassicaceae), previously cruciferous family, accumulate high selenium concentration. Broccoli plants   are   good   source of bioactive compounds (phytochemicals   compounds), as vitamins, essential minerals glucosinolate, and phenolic compounds. Glucosinolates (GLs) classified as a secondary metabolites, mainly found in Brassicaceae, which may act against various types of disease as   cancers. Exogenous application of selenium in broccoli stimulates the accumulation of glucosinolates concentration through promoting gene transcript involved in glucosinolate production. The main aim of this study is to determine the relationship between Se availability in soil and accumulation of glucosinolates compounds in broccoli sprouts) Immature inflorescence).
