초록

본 연구는 국내 '설향' 딸기 품종의 삽목 육묘 시 초기 활착을 증진시키고 묘소질을 향상시키기 위한 삽수 채취시기와 오옥신계 식물생장조절제 IBA, NAA의 적정 처리농도 구명을 위하여 수행되었다. 딸기 삽수는 6월 7일과 7월 5일의 두 차례에 걸쳐 채취했으며, IBA와 NAA는 각각 0.025, 0.05, 0.1%의 농도로 침지 처리하였다. 삽목한 묘는 터널재배 후 18일 동안 6회에 걸쳐 생존율을 조사하였다. 삽수 채취시기와 관계없이 NAA 처리에서는 묘 고사율이 높아, 딸기 삽목 육묘 시에는 NAA 처리가 부적합하였다. 삽수 채취시기와 식물생장조절제가 묘 생육에 미치는 영향을 조사한 결과 6월 채취묘는 IBA 0.1%에서, 7월 채취묘는 IBA 0.05%에서 묘의 활력이 우수하였다. 광합성 효율을 조사한 결과 6월 채취묘는 IBA 0.1%에서, 7월 채취묘는 IBA 0.05%에서 양자수율이 높았다. 따라서, 딸기 삽목묘의 생육을 증진시키기 위해서는 NAA보다 IBA를 사용하는 것이 적절하며, 이때 6월 삽수 채취 시에는 0.1%, 7월 삽수 채취 시에는 0.05%의 농도로 이용하는 것이 보다 적합한 것으로 판단되었다.

The aim of this study was to investigate the effects of timing of collecting date and concentration of IBA and NAA, in order to enhance initial activity and seedling quality of domestic strawberry. Strawberry cuttings were separately taken twice, in June 7 and in July 5, and IBA and NAA were treated with the concentrations of 0.025, 0.05 and 0.1% at cutting date, respectively. The seedlings were evaluated for the percentage of survival during 18 days at 6 times after tunnel cultivation. The NAA treatment was inappropriate for strawberry cutting due to the high rate of seedling mortality, regardless of the collecting date. The vitality of the seedlings was highest at IBA 0.1% in June collecting and at IBA 0.05% in July collecting. The seedlings from June collecting had a higher quantum yield at IBA 0.1% and the seedlings from July collecting at IBA 0.05%. Therefore, IBA could be more effectively applied than NAA to promote the vitality and quality with the appropriate concentration of 0.1% at June collecting and 0.05% at July collecting, respectively.
