Abstract
Growth characteristics according to mixture ratio of used-rockwool in pot nursery, in Pinus densiflora, Torreya nucifera, Quercus acutissina and Fraxinus mandshurica nursery, was investigated. The used-rockwool on mixture ratio between used-rockwool and control (peatmoss: pearlite=1:1, v/v) were 0%, 30%, 50% and 70%. Flesh weight, dry weight and height of tree, in Pinus densiflora nursery, increased much more in 50% and 70% media but trunk diameter of tree had no difference according to mixture ratio. In Torreya nucifera nursery, flesh weight and height of tree in 70% medium and trunk diameter and numbers of shoot of tree in 50% and 70% media increased. Flesh weight, height and trunk diameter of tree, and chlorophyll (SPAD) and photosynthesis rate, in Quercus acutissina nursery, increased much more in 50% and 70% media, but dry weight of tree had only difference between non-mixed and mixed with rockwool. In Fraxinus mandshurica nursery, flesh weight and photosynthesis rate of tree increased much more in 70% medium, height, trunk diameter and total chlorophyll of tree had difference according to non-mixed and mixed with rockwool or had no only difference according to mixture ratio, respectively.
