we applied 4 sorts of sulfur-containing fertilizers like sulfur, magnesium sulfate, potassium sulfate and ammonium
sulfate. The yields of wasabi leaves were decreased by 3 to 18% when applied sulfur-containing fertilizers. The
content of Sinigrin didn't show any difference but that of Allyl isothiocyanate, when applied 3 sorts of sulfur
fertilizers except for sulfur, increased in the leaves. Among the 3 sulfur fertilizers, potassium sulfate appeared to be
the most effective on elevation of the Allyl isothiocyanate content. The content of Allyl isothiocyanate in the plot
of potassium sulfate application showed 404.4 mg/gDW, 101 mg/gDW higher than the control plot. This is because
Sinigrin was hydrolyzed into Allyl isothiocyanate by myrosinase. Thus, the analysis of Allyl isothiocyanate as well
as Sinigrin is considered to be needed for the flavor and taste of wasabi. According to this result, we concluded that
the techniques for controlling flavor and taste of wasabi can be developed using some sorts of sulfur fertilizers.
