| Abstract: | The radish (Raphanus sativus) is a root vegetable of the Brassicaceae family which shows amylolytic activity in the taproot. However, there is little
information about differences in these amylolytic activities among radish cultivars. We analyzed the amylase activities and
starch contents of 7 kinds of radish cultivars. The Koshin cultivar showed the highest amylase activity, with a level approximately
6 times higher than that of the Sobutori cultivar, which had the lowest. Cultivars with higher amylase activities showed higher
starch contents. These results suggest that there are intraspecies variations in amylolytic activities in radishes, and positive
correlations between amylase activity and starch content. |
