摘要：

Dry matter production was determined for Eucalyptus camaldulensis aged 2-14 years in Puttalam and Moneragala in Sri Lanka. Total dry biomass ranged up to 163 t ha-1 at 14 years at which point the root system accounted for 5% of the total. The root:shoot ratio declined steadily from a maximum at age 2 of 0.145. Mean annual production per hectare peaked between 10 and 12 years on both sites. Mean annual leaf efficiency index was at a maximum of 4.05 at 4 years (top height 9.2 m). Total above-ground dry weight could be accurately predicted from mean breast height diameter.
