ABSTRACT
This research was performed to analyze growth performance and pattern of eighteen families of hinoki cypress (Chamaecyparis obtusa), which were imported in Jeju region. The growths of ‘Yako-7′, ‘Muei-1′, and ‘Sangsong-9′ families were superior to other families whereas those of ‘Sanguen-3′, ‘Yago-6′, and ‘Hyena-2′ families were poor. The height growth between age 9-year to 15-year was superior to those between other ages. No specific growth pattern was observed in the diameter at breast height (DBH) by ages. Family heritability of height, DBH, and volume were estimated at 0.68, 0.75, and 0.75, respectively. Pearson’s correlation analysis showed that there was little juvenile-mature correlation in the growth of C. obtusa.

적요

제주지역에 도입된 편백 18가계의 초기 생장부터 현재(42년생) 까지의 연령별 수고, 흉고직경, 재적생장을 분석하였다. Yako-7, Muei-1, Sangsong-9 가계가 우수한 생장을 하였으며, Sangeun-3, Yago-6, Hyena-2 가계의 생장이 저조한 것으로 나타났다. 연령별 평균생장을 분석한 결과, 수고생장은 9년생에서 15년생 사이의 생장이 다른 연령대에 비해 우수하였으며, 흉고직경의 생장은 특별한 경향이 관찰되지 않았다. 수고, 흉고직경, 재적의 가계유전력은 각각 0.68, 0.75, 0.75로 추정되었으며, 연령간의 생장을 비교한 결과, 유노상관 관계는 없는 것으로 판명되었다.
