Abstract

An analysis of wood chemical composition was carried out for eight poplars, of which four (Populus adenopoda, P.eura cv. `I-214, P.deltoides cv.`Lux and P.deltoides cv. `Havard) sampled from south of China and four (P.deltoides ev. `Zs-5, p. popu-eura cv. `28-77, P.deltoides cv. `Zj- 2 and P.popularis cv. `Zj-10)from north of China. The results showed that the averaged contents of water, ash and benzene-alcohol extractives were low, 9.69%, 0.68% and 1.74% respectively. The contents of cellulose and holocellulose were high, 48.76% and 77.19% respectively; and lignin and pentosans were 21.54% and 21.72% respectively. With respect to the criteria required for pulpwood, these poplars were all of superior pulping material. The four northern species, however, were better than the sourthern four.
