This paper analyzes the effects of branch age,moisture content and density of fresh branches of evergreen and deciduous trees during the period of dormancy on the modulus of elasticity( MOE) by adding the dummy variable into regression model. These branches were from the seven species( five deciduous trees and 2 evergreen trees in December 2012,including 40-year-old Pinus tabulaeformis,30-year-old Platycladus orientalis,12-year-old Ailanthus altissima,20-year-old Robinia pseudoacacia,30-year-old Koelreuteri...
