초록

옥잠화속식물중잎의무늬가다양하고절엽수명도길어절엽용품종으로적합한 ‘Ellerbroek’, ‘Francee’, ‘Halcyon’의 3품종을대상으로번식효율을높이기위한생장조절제인 BA 및물리적처리방법간의액아발생촉진효과를구명하고자수행하였다. BA의처리시 기및농도별액아발생정도는무처리에비해월등한효과가입증되지않았다. 물리적처리방법별액아발생정도는지상부절단방법보다는기부상처가더효과적이었다. ‘Ellerbroek’에서는처리방법간에액아발생증가효과가그다지크지않았으나 ‘Halcyon’에서는무처리에비해기부상처가주당 4개의액아수가증가되었다. 또한 ‘Francee’에서는액아발생수가 BA처리나지상부절단방법이 주당 2개와 1.8개인데반해기부상처시주당 6.1개로액아발생촉진효과가가장뛰어났다.

영어초록

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 culti-vars, ‘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 gen-eration 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 cut-ting. 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, respec-tively, it was 6.1 by base wounding, indicating the greatest effect on promotion of axillary bud generation among all treatments.
