Abstract

A single sample of Pinus oocarpa from Mountain Pine Ridge, Belize was pulped by the sulphate process. The results of pulping and pulp evaluation, together with chemical analysis of the wood and fibre dimensions are reported. The sample consisted of twenty trees selected at random from a naturally regenerating forest. The average age of the trees was estimated as 30 years with a range of 20 to 46 years. Chemical analysis showed the wood to have an a-cellulose content of 48.9% and a lignin content of 28.7%. The fibres were 3.13 mm long, 49.8 micrometres wide and had walls 6.9 micrometres thick. Pulping by the sulphate process yielded between 38% and 44% of unbleached pulp. These yields were lower than usually found in pines. The pulp had strength characteristics generally similar to those of pulps from Southern Pines of the USA. Compared with pulps obtained from P. caribaea growing in the same area, it was found that P. oocarpa gave lower yields of marginally better pulps.
