Abstract

This study was carried to investigate effects of optimum supply strengths of 'Sonneveld' nutrient solution on growth characteristics in container seedling of trees (Pinus densiflora, Torreya nucifera, Quercus acutissina and Fraxinus mandshurica) using developed media with used-rockwool. Flesh weight, height and trunk diameter in container seedling of Torreya nucifera were better in high strengths. In container seed ling of Torreya nucifera, flesh weight more increased in 1.5 and 3.0 strengths and hight and trunk diameter more increased in 1.5 strength than the rest. Flesh weight in container seedling of Quercus acutissina was heaviest in 2.0 strength and was lightest in 1.0 strength. Height and dry weight in 2.0 and 3.0 strengths and trunk diameter and total chlorophyll in 2.0 strength were better than in the rest. Besides photosynthesis rate was more high in 1.5 and 2.0 strengths than in the rest. In container seedling of Fraxinus mandshurica, flesh weight, height and trunk diameter more increased in 0.5 strength and total chlorophyll and photosynthesis rate were good in 0.5 and 2.0 strengths. Most growth characteristics were poor in 3.0 strength.

침엽수종인 소나무(Pinus densiflora)와 비자나무(Torreya nucifera), 활엽수종인 상수리나무(Quercus acutissina)와 들메나무(Fraxinus mandshurica)를 대상으로 수경 재배를 이용한 우량 용기묘 생산 시 'Sonneveld' 배양액의 적정 농도를 구명하기 위해 수행하였다. 배양액의 공급 농도에 따른 소나무(0-0)의 생체중, 수고 및 원줄기 직경은 모두 높은 농도일수록 높은 경향을 나타내며 3.0배액에서 가장 높았다. 비자나무(1-1)의 생체중은 1.5배액과 3.배액에서 많이 증가하였고 수고와 원줄기 직경은 1.5 배액에서 가장 많이 증가하였다. 상수리나무(0-0)의 생체중은 2.0배액에서 가장 무거웠고 1.0배액에서 가장 가벼웠다. 수고와 건물중은 모두 2.0배액과 3.0배액에서 좋았고, 원줄기 직경과 엽록소 함량은 2.0배액에서 좋았다. 또한 광합성은 1.5배액과 2.0배액에서 활발하였다. 들메나무(1-1)의 생체중, 수고 및 원줄기 직경은 0.5배액에서 가장 많이 증가하였고, 엽록소 함량과 광합성은 0.5배액과 2.0배액에서 좋았다. 그리고 대부분의 생육 특성은 3.0배액에서 저조하였다.
