Regression Analytical Studies on the Resin Canal and Resin-Producing Capacity of Pinus massoniana
Zhu Qiu · Journal of Fujian Forestry Science and Technology · 2002
The results indicate that the resin canal number has a close relationship with resinproducing capacity,through the fitting with 16 regression equations,the optimal regression equations between resin canal number and Pinus massoniana daily resinproducing yield,between resin canal number and 10 cm long side gutter resinproducing yield as well as between resin canal number and adjusted resinproducing yield are the following respectively:①Y=(7102+120703X)/X,r=0848;②Y=(0789+12300X)/X,r=0762;③Y=(4842+80362X)/X,r=0664.
