Abstracts

In order to research changes of asparagine content according to stage after harvest to storage, it was analysed asparagine content of potato tuber and potato sprout. The results of the asparagine content in potato cultivars after harvest ranked in cv. Superior, cv. Gahwang, cv. Atlantic and cv. Goun in descending order. The content of asparagine in potato was approximately 1300 mg/100g (D.W.) The changes the asparagine content according to storage condition and the difference of asparagine between tuber and sprout can be summarized as follows. In the asparagine content of potato cultivars, Little variation in the content was observed while potato tubers were stored at $4^{\circ}C$. However, after 3 months of storage at $10^{\circ}C$, the content increased by 9.7%, indicating that the content increases as the storage temperature and period increases. The content of asparagine also increased during sprouting of potato tubers. In the sprout, the proximal region contained 21% higher content of asparagines than the distal region, which suggests that the sprout develops with the increasing of the content of asparagines.
