“…The model can be used to accurately assess effect of intensive silvicultural treatments, such as spacing, site preparation and provenance trials, on stem form and volume growth. Stem volume has been found to be highly correlated with aboveground biomass or carbon (e.g., Adu-Bredu et al, 1997). The model can therefore form a basis of using allometric relationships to estimate aboveground carbon accumulated in teak stands, when branch and foliage biomass are available.…”

“…Measurements of tree height, stem girths at 50‐cm intervals (starting from ground level) and at the crown base were recorded. Adu‐Bredu et al . (1997b,c) examined the allometric relationship between above‐ground phytomass, w (kg tree −1 ) and stem volume, v (dm 3 tree −1 ) on the basis of 19 destructively sampled hinoki trees from the vicinity of the stand.…”

The carbon budget of the above‐ground parts of a young hinoki (Chamaecyparis obtusa) stand was analyzed over a 4‐year period to evaluate trends in changes in carbon use efficiency and growth conversion (biosynthetic) efficiency with stand development. Litter production of the stand was estimated from the stem cross‐sectional area at the crown base. A biomass increment was estimated using the stem volume of individual trees in the stand, measured at monthly intervals. Net production, estimated from litter production and the biomass increment, was 7.40, 8.44, 8.45 and 8.29 Mg C ha−1 year−1 for Years I–IV, respectively. The respiration rate of the entire above‐ground parts of selected sample trees were measured at monthly intervals using the enclosed whole‐tree method. The Q10 value of respiration decreased with increasing air temperature. Respiration rate was partitioned into growth and maintenance components using a two‐component functional model. The maintenance respiration coefficient increased in the following order: winter, spring, autumn and summer. The maintenance respiration coefficient also decreased with either stand development or age for all seasons. The growth respiration coefficient, which did not vary with stand development, was 0.69 ± 0.08 (mean ± SE), 0.61 ± 0.03, 0.54 ± 0.03 and 0.67 ± 0.07 g C g−1 C for winter, spring, summer and autumn, respectively. The growth conversion efficiency of the stand was 0.76, 0.72, 0.72 and 0.75 for Years I–IV, respectively. Carbon use efficiency was estimated to be 0.58, 0.57, 0.54 and 0.53 for Years I–IV, respectively. The hypothesis that respiration reduces productivity in old stands could not be validated for this hinoki stand.

“…Our results showed that the annual increments of DBH and height of A. crassicarpa (3.7 cm, 2.8 m) were significantly lower that that of E. urophylla (7.8 cm, 3.6 m). It was reported that the growth respiration rate would increase with the rate of biomass increment (Adu-Bredu et al, 1997;Ceschia et al, 2002).…”
