The effects of Sand N fertilizations on sprout growth and the contents of individual glucosinolates in broccoli (Brassica oleracea var. italica) were investigated using sprout culture system. Broccoli sprouts were cultivated by fertilizing with combinations of S (0, 10, 20, 40, and 80 ㎎ㆍL?¹) and N concentrations (0, 25, 50, and 100 ㎎ㆍL?¹) at 25℃. The growth of sprouts increased progressively in proportion to N concentration, while the increase was partly arrested with the higher S levels in culture solution, concomitantly showing abnormal cotyledon expansion. A total of ten desulfoglucosinolates were identified and the variation of individual and total glucosinolate contents were significantly affected by S and N fertilization. Herein the S levels were shown to be more significant factors than N levels for the contents of glucosinolates. The significantly higher contents of total glucosinolate were observed in the sprouts cultivated on S level of 80 ㎎ㆍL?¹, performing the increase of some major glucosinolates, such as progoitrin, glucoraphanin, gluconasturtiin, and 4-methoxyglucobrassicin. Consequently, the total and individual glucosinolate contents of broccoli sprouts could be changed and increased with S and N levels. This trials showed that the regulation of S and N levels in culture solution could be good method for high quality sprout production.
