摘要：
Kraft pulping and pulp strength characteristics were determined for samples of Pinus patula and Pinus elliottii grown across a range of altitudes from 790 to 1460 m a.s.l. and representing felling ages of 11-25 years. Intrinsic species differences, felling age, and site altitude all had a significant influence on pulping characteristics. Pulp yield characteristics differed between the two species but not site altitude or felling age. Pulp strength variation was related to felling age and the influence of altitude on the intrinsic characteristics of the two species.
