국문 초록

차나무의 몇가지 품종에 대한 영양계 번식방법 중 삽목기술 개선을 위해 삽목시기(녹지삽과 숙지삽), 발근 촉진을 위한 IAA, NAA, IBA등의 생장조정제의 종류 및 처리효과를 검토하여 차나무 우량묘목 생산체계를 정립하고자 한 결과는 다음과 같았다. 삽수채취시기에 따른 효과는 녹지삽이 숙지삽에 비해 발근율과 생존율이 90.6%, 89.5%로 높았으며, 뿌리생장도 녹지삽에서 큰 차이를 나타냈다. 생장조정제의 처리 효과는 IBA>NAA>IAA>무처리 순으로 나타났으며, 순간침지 삽목기술은 이용이 쉽고 평균적인 발근과 생육 효율이 매우 양호하였다. 삽목번식시 품종별 발근 및 생육을 고려할 때, 사에미도리는 논ㄱ지삽이 좋았으며, 후슌은 숙지삽도 권장할 만 하였다.

영문 초록

The study was conducted to investigate the effect of growth regulators on rooting Tea cultivars(Camellia sinensis) by hardwood and softwood cutting. The growth regulators were used IAA, NAA, IBA etc. Cutting was prepared 2 node size and a tip cut with 45˚. Cutting medias were consisted of volcanic soil in Juju. The growth regulators were solved in (99%) absolute ethyl alcohol with concentrations of 3,000mg L⁻¹. After dipping in the solutions for 2~3 second(namely quick dip method), the cuttings were inserted into cutting media. The results are summarized as follows ; During the cutting period, Softwood cutting showed the best rooting ratio and survival ratio. at that time, rooting ratio was 90.6% and survival ratio was 89.5%. The growth of root was the value at Softwood cutting. The result of growth regulators shown the effect on increase of root growth in IBA>NAA>IAA>control plot. At the cutting with quick dip method, the top and root of growth regulators treatment plot was better than those of control plot. At the cutting time of optimum recommended, Saemidori was good at softwood cutting.
