Variation of wood basic density, pulp yield and other wood properties for four eucalyptus clones in Stora Enso Guangxi (China) plantation

Abstract [en]

Stora Enso Guangxi is developing eucalyptus plantations in southern Guangxi for a future pulp and paper industry. The genetic compositions vary between the eucalyptus clones and it is likely that their wood properties and pulp yield are also very different. The project is to assess and analyze the variation of Wood Basic Density, Pulp Yield and Pulp Production between selected eucalyptus clones in Stora Enso Guangxi plantation. These work and data as preparative and indicator in chemical pulping. Four eucalyptus clones in Stora Enso Guangxi plantations have been selected for research. 3 trees from each clone were felled, in all 12 trees from 4 clones. The 12 trees were in the same age, in the same fertilization and in the same plantation. The variation of the 3 trees within each clone would be small. The studied 4 clones are DH201-2 (grandis x camaldulensis), DH32-13 (urophylla x grandis), U6 (urophylla x tereticornis), SH1 (urophylla x ecerta). The clone DH201-2 is showing the highest wood basic density of the 4 clones, and there is significant difference with the other 3 clones. There are indications of clone DH32-13 is showing the lowest mean density. The bark volume of clone U6 is higher than clone SH1: the differences between them are significant. There are indications of clone U6 is showing the highest bark volume percentage and clone SH1 is showing the lowest bark volume percentage. There are indications of clone U6 is showing the lowest total pulp yield at Kappa 18 of the 4 clones. Clones DH201-2 is showing the highest value in pulp production. Clones U6 is showing the lowest value in pulp production. In this project, the clones DH201-2 is showing the highest value in the pulping of the 4 clones, clones U6 is showing the lowest value in pulp production of the 4 clones, although just one project cannot fully determine the entire value of the 4 clones. It is a suggestion that the eucalyptus plantations in southern Guangxi for a future pulp/ paper industry, should based on clone DH201-2, and avoid clone U6.
