Abstract
This study was conducted to investigate the effects of BA, a growth regulator on enhancing propagation efficiency, and physical treatment on promotion of axillary bud generation in three hosta cultivars, 'Ellerbroek', 'Francee', and 'Halcyon'. These are cultivars suitable for cut foliage production among Hosta spp. because of their diverse leaf patterns and long vase life of cut foliage. The degree of axillary bud generation by treatment time and concentration of BA has not been proven to be extraordinarily effective as compared to not treated control. As a physical treatment, base wounding was more effective than stem cutting. In 'Ellerbroek', increase of axillary bud generation among treatment methods was not great. However, in 'Halcyon', base wounding had four more axillary buds per plant than not treated control. In addition, although number of axillary buds increased per plant by BA treatment and stem cutting was 2 and 1.8, respectively, it was 6.1 by base wounding, indicating the greatest effect on promotion of axillary bud generation among all treatments.
옥잠화속 식물 중 잎의 무늬가 다양하고 절엽 수명도 길어 절엽용 품종으로 적합한 'Ellerbroek', 'Francee', 'Halcyon'의 3품종을 대상으로 번식 효율을 높이기 위한 생장조절제인 BA 및 물리적 처리방법간의 액아발생 촉진 효과를 구명하고자 수행하였다. BA의 처리시기 및 농도별 액아 발생정도는 무처리에 비해 월등한 효과가 입증되지 않았다. 물리적 처리방법별 액아 발생 정도는 지상부 절단방법보다는 기부 상처가 더 효과적이었다. 'Ellerbroek'에서는 처리 방법 간에 액아 발생 증가 효과가 그다지 크지 않았으나 'Halcyon'에서는 무처리에 비해 기부 상처가 주당 4개의 액아수가 증가되었다. 또한 'Francee'에서는 액아 발생수가 BA처리나 지상부 절단 방법이 각각 주당 2개와 1.8개인데 반해 기부 상처시 주당 6.1개로 액아 발생 촉진 효과가 가장 뛰어났다.
