Abstract

This study was conducted to find out a proper cutting time as related with a growth pattern for the mass propagation of Corylopsis coreana, which is one of the Korean endemic plant. New shoots began to grow in early April soon after end of blooming time and grew rapidly until the end of June. Shoot growth became dull after June and stopped in early September, showing a typical primary growth curve of temperate deciduous trees which show only one flush of growth throughout an annual growth cycle. The moisture content of shoot was the highest in an early growing season of May, and decreased with shoot maturity. Moisture content of cuttings taken on June 20 was 71.2%. Rooting was better in softwood cuttings than in hardwood cuttings. The highest value of rooting percentage was obtained in cuttings taken on June 20.

본 연구는 한국특산식물인 히어리의 대량번식을 위하여 생장패턴과 관련한 삽목적기를 알아보고자 수행되었다. 히어리의 신초는 4월초 개화 직후에 발생이 되었다. 발생한 신초는 6월말까지 급속하게 생장을 하다가 그 후에는 생장속도가 다소 둔화되어 정지하는 전형적인 온대성 낙엽활엽수의 1차적인 생장곡선을 나타내었다. 삽수의 수분함량은 신초발생 이후 5월까지 증가하다가 그 후 수분이 감소하는 경향이었다. 6월 20일의 수분함량은 71.2%였다. 히어리는 숙지삽에 비해 당년지를 이용한 녹지삽이 삽목번식에 유리하였다. 당년지를 삽목한 5월부터 9월까지도 삽목시기에 따라 큰 차이가 있었는데, 특히 6월 20일에 삽목하였을때 발근력이 타 시기에 비해 월등하게 좋았다.
