Background: In order to cultivate upland crops in reclaimed land, suitable crops are selected as economic crops. Jerusalem artichoke (Helianthus tuberosus L.) is one of the primary sources for inulin in higher plants. The objective of this study was to evaluate and compare H. tuberosus L. growth and inulin according to the cultivation region in Korea.
Methods and Results: 21 varieties of H. tuberosus L. were collected in Korea, then varieties of 7 H. tuberosus L. were selected. To compare growth and inulin, that cultivated in reclaimed land and upland soils. The growth of H. tuberosus L. significantly decreased when cultivated in reclaimed land. there was increased 17.8% in the content of white H. tuberosus L. tuber inulin in reclaimed land.
Conclusions: The content of inulin in H. tuberosus L. tubers was found to depend on cultivation region and tuber color. There was a difference between the inulin content of the tuber color in reclaimed land, Purple tubers of P20 was considered suitable varieties for cultivation in reclaimed land. White tubers of W1 and W8 were also considered suitable varieties for cultivation in reclaimed land.
