Cryptomeria japonica Gi*(d) statistics needle nitrogen content spatial variation temperature
2009/8/24
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...
The relationship between the form of dead bark and lignin content in Scots pine (Pinus sylvestris L.)
Form of dead bark lignin content Pinus sylvestris L.
2010/1/11
In this study the proportion of lignin in wood tissue was analysed in 36 Scots pines differing in their form of dead bark. Material for analyses came from pure pine stands aged 89-91 years located in...
