Abstract

This study was carried out to investigate the relationship between anatomical characteristics and growth rate of Quercus rubra from different origins of seed. Anatomical characteristics showed that all Quercus rubra species were ring-porous woods with 1~3 layers of large pores in earlywood, but the latewood had small pores oriented in radial direction. There were slight differences in libriform fiber length and vessel element diameter in the earlywood among different provenance origins of seeds. In growth rate, the libriform fiber length and vessel element diameter was negative correlation in the earlywood, but not correlative in the latewood, and vessel element length was not correlative in the early and latewood, Volumetric composition of libriform fiber and ray in latewood was higher than those in ear lywood, and a higher composition of vessel element was observed in earlywood. Ray height was the range of from 11 to 15 cells.

본 연구는 5개 종자 산지(Carleton, Simcoe, Chatham, Bancroft, Unknown)의 루브라참나무(Quercus rubra)를 대상으로 해부학적 성질을 조사하여, 이들의 종자산지 간 및 생장속도와의 관계를 규명하였다. 루브라참나무는 환공재로서 공권부는 대형도관이 1~3열로 배열하다가 공권 외부는 소형도관이 방사상으로 배열하였다. 산지 간에는 조재부 목섬유 길이, 조재부 도관의 직경에서만 차이가 있었다. 생장속도와는 목섬유 길이 및 도관요소 직경에서 만재부는 상관관계가 없고, 조재부는 부의 상관이었다. 도관요소 길이는 생장속도와 조, 만재에서 관계가 없었다. 조, 만재부에서의 구성요소 비율은 목섬유, 방사조직은 만재부에서 높았고, 도관요소는 조재부에서 높았다. 방사조직 높이는 11~15개 범위였다.
