Abstract

Achyranthes bidentata was recorded to new medicinal crop in a revised 8th edition of the Korean pharmacopoeia. Therefore, A. bidentata began to use for same purpose with Achyranthes japonica which was cultivated since old times in Korea. This study was conducted to investigate the adaptability of A. bidentata in Korea. The germination rate and speed of A. bidentata seeds were higher than those of A. japonica in 15℃ and 25℃. The growth of A. bidentata was greater than that of A. japonica until the 60 days after transplanting, but growth after that was the opposite. There were remarkable differences between two species in growth characteristics such as flowering date, leaf fall date, plant height, stem color and no. of branches. The flowering and leaf fall date of A. bidentata were earlier than A. japonica by July 7 and September 26. The plant height and number of branches of A. japonica were longer and more than A. bidentata, but the cluster length and no. of flowers per cluster of that were shorter and fewer than this. Number of supporting roots of A. bidentata and A. japonica was 10.7 and 14.6 per plant, respectively. The average yield was not different between two species. The yield of A. bidentata was 166 ㎏/10 a in Suwon and 309 ㎏/10 a in Naju of Korea. The suitable cultivation region of A. bidentata was judged to southern area of Korea.
