Pulping characteristics of Eucalyptus provenance trials grown in the Western Cape. Part 2: Pulping properties of E. dunnii grown from seed of three provenances
For the purpose of Part 2 of this investigation, 14-year-old E. dunnii trees grown from seed of three different localities in Australia were chipped, screened and pulped using the Kraft process. The trees grown from seedlots 10411 and 11705 yielded high percentages of pulp (approximately 48 to 49 per cent). The pulp strength properties (breaking length, burst index and tear index) of these two E. dunnii provenances were substantially higher than those of provenance 11786. The total chemical demand of provenance 10411 was higher than those of 11705 and 11786. Data on E. globulus and E. nitens are not yet available.
