초록

본 연구는 국내 자생 긴산꼬리풀의 관상식물로서 활용을 위하여 적심 후 BA 엽면살포의 효과에 대해 알아보기 위하여 실시하였다. 긴산꼬리풀이 10 cm 정도 자랐을 때 적심 0, 1, 2 주 후 0, 500, 1000, 2000 mg/L의 BA를 엽면살포하여 식물의 생육과 개화 특성을 살펴보았다. 긴산꼬리풀의 분지 형성은 적심 1주 후 2000 mg/L를 처리하였을 시 가장 우수하게 나타났으며, 모든 처리구에서 왜성화 효과가 나타났다. 또한 첫 개화일수가 BA 처리구에서 지연되는 효과가 있었으며, 꽃의 길이와 화서의 길이가 감소하는 경향을 보였다. 본 연구결과를 통하여 국내 긴산꼬리풀의 적심과 BA 엽면살포가 관상식물로써의 활용 능력을 증대시킬 수 있을 것이라 판단된다.

This research was conducted to investigate the effect of foliar application of 6-benzylaminopurine (BA), sprayed weeks after pinching (SWP), on ornamental usage of Veronica longifolia L, which is native to Korea. Foliar application of 0, 500, 1,000, and 2,000 mg/L BA on 10 cm long V. longifolia L. plant was evaluated at 0, 7, and 14 days after pinching for growth and flowering. The maximum result of multiple shooting was seen in the 2,000 mg/L BA at 1 week after pinching, and almost all the treatments showed dwarf growth in V. longifolia L. The number of days to flowering was delayed by BA treatments. Moreover, the length and the number of flowers decreased with high concentrations of BA. Thus, foliar application of BA via pinching technique can improve the ornamental usage of V. longifolia L. by controlling the plant type.
