摘　　要：研究马尾松木材化学组分、制浆性能在群体中的变异及不同伐龄木材制浆造纸适应性。结果表明上述性状在天然群体和种源试验林群体中都存在一定变异，具有一定选择潜力。试验发现２０年生伐龄木材制浆性能有一定优越性。采用短周期速生材造纸是可行的，但其关键在于选育幼龄材木材密度高的品系。This experiment examined natural population varition in chemical constituents and pulping properties of Pinus massoniana Lamb . wood and their pulpability at different ages.Results show that there are certain variation and selection potentials in the populations and provenances of the species.It is of advantage to use P. massoniana wood at 20 years age for pulping. It is feasible to obtain pulps from shortrotation,fastgrowing wood.The key to the settement of the question lies in breeding of the varieties, juvenile wood possessing high wood specific gravity.
