We investigated paternal contribution in artificial crossed-populations made by mixed pollen from plus tree clones of Cryptomeria japonica D. Don in Niigata Prefecture. Using six polymorphic microsate...
Knowledge of nitrogen mineralization in the soils of sugi (Cryptomeria japonica) stands is important for understanding the effects of forest management and environmental changes on nutrient cycling in...
Two C. japonica trees exhibiting male sterility were found in Niigata Prefecture, Japan. These trees exhibited not only male sterility but also female sterility, because their seeds did not germinate....
In order to shorten the period required to select sterile trees from the mating family of male-sterile Cryptomeria japonica D. Don lines, germinated male-sterile C. japonica seeds were planted in spha...
An optimum allocation of selection weight on the traits that were related to carbon storage in the stem of sugi was investigated to establish criteria for choosing plus tree clones suitable for carbon...
We investigated past growth of trees within a natural stand of Cryptomeria japonica in Sado Forest Reserve, Akita Prefecture, northeastern Japan, relating to temporal changes in environmental conditio...
I studied the comparison of juvenile growth characteristics of cuttings and seedlings of sugi (Cryptomeria japonica) in heavy snowfall region. I selected three pairs of a seedling-trial and a cutting-...
To clarify the causal fungus of butt rot disease of Cryptomeria japonica (Sugi), we isolated basidiomycetous fungi from decayed stumps in 12 plantations 40 to 83 years old in the Aso district, Kumamot...
The pattern of growth in 10 Japanese cedar (Cryptomeria japonica) trees (age 162 to 255 years) located within a natural forest was analyzed using ring-width data. These trees showed a rapid increase i...
We have developed new type compost with waste sludge from a bean curd factory and applied it to the cutting bed of Cryptomeria japonica D. Don. The effects of the compost on the elongation of root and...
For a general assessment of the nitrogen status of sugi plantations in Japan, we measured nitrogen content in the needles of sugi (Cryptomeria japonica D. Don) trees growing at 531 sites across the co...
