Growth characteristics of Kawaidani-Sugi (Cryptomeria japonica D.Don)
2020
Aiura, H.
The growth characteristics of Kawaidani-Sugi (Cryptomeria japonica D. Don), widely planted in the northwestern part of Toyama Prefecture were investigated. Until 30-year old, the tree height growth, increment of diameter and stand volume were good, but after 30-year old, growth rate declined and plateaued. Therefore, it was thought that Kawaidani-Sugi is an early variety. In addition, snow damage also occurred after 30-year old. The height-dbh ratio to avoid this damage was considered to be about 65. Due to these growth characteristics, Kawaidani-Sugi was considered to be a suitable variety for short rotation.
