Abstract
This experiment was conducted to evaluate the contents of allylisothiocyanate and the change of hardness of the rhizome part of Wasabia japonica Matsum. by months after planting in water cultivation. No difference was found in plant height and leaf length at 10th and 15th months after planting, respectively. The rhizome part of wasabi was cut half and the dry weight was weighed. Dry weight was obtained as 17.3% and 21.6% from fresh lower and upper part of rhizome at 10th month after planting. At 15th month after planting, dry weight was obtained as 21.2% and 22.3% from fresh lower and upper part of rhizome. The contents of allylisothiocyanate were 0.047 mg/g and 0.633 mg/g at 10th and 15th month, respectively.
