“…y Biomass in kg ha -1 and x diameter in cm. Pooled data from all six age series plantations (1, 5, 11, 18, 24, 30 years) Carbon storage and sequestration rate assessment and allometric model development in young… over DBH-based regressions resulting from inclusion of H along with DBH in the present study differed from the finding of Kumar et al (1998) for multipurpose trees, Lim et al (2013) for Japanese Cedar, Komiyama et al (2000) for secondary mangrove forest and the general observation of Nihlgard (1972) that DBH 2 H resulted in stronger correlation. However, Nelson et al (1999) suggested that DBH alone is a very good predictor of species-specific regression (up to 95 % accuracy for Eucalyptus, Kuyah et al 2013).…”

“…This could be due to different growing conditions of the stands. Moreover, the age of stand and nutrient status of soil (Scarascia-Mugnozza et al 1997;Kajimoto et al 1999;Sharma et al 2002;Agren and Franklin 2003;Greenwood et al 2007;Lim et al 2013), spacing of trees and water availability (Barton and Montagu 2006) have been recognized as factors affecting root biomass accumulation. Wang et al (2008) and Luo et al (2012) suggested that RSR also depended on forest type and climate.…”

Carbon (C) sequestration through plantations is one of the important mitigation measures for rising levels of carbon dioxide and other greenhouse gases in the atmosphere. This study aimed to assess C stocks and their sequestration rate, and to develop allometric models for estimation of C stocking in age-series young teak (Tectona grandis) plantations (1, 5, 11, 18, 24 and 30 years) by using biomass and productivity estimation and regression, respectively. These plantations were raised in tropical moist deciduous forests of Kumaun Himalayan tarai. Total C stocks estimated for these plantations were 1.6, 15.8, 35.4, 39.0, 61.5 and 73.2 Mg ha -1 , respectively. Aboveground and belowground C storage increased with increasing plantation age; however, the range of their percentage contribution showed little variation (87.8-88.2 and 11.7-12.7 %, respectively). The rate of C sequestration for these respective plantations was 1.06, 6.95, 5.46, 5.42, 3.39 and 5.37 Mg ha -1 a -1 . Forty percent of the aboveground annual storage was retained in the tree while 60 % was released in the form of foliage, twigs, and fruit litter. In the case of total (tree) annual production, 43 % was retained while 57 % was released as litter including root. C stock, C sequestration rate, accumulation ratio (1.4-18.1), root:shoot C ratio (0.61-0.13) and production efficiency (0.01-0.18) were comparable to some previous reports for other species and forests. These data could be useful in deciding the harvesting age for young teak with respect to C storage and sequestration rate. Four allometric models using linear regression equations were developed between biomass (twice the C stock) and diameter, girth, and height of the tree at different ages. The diameter model was found more suitable for C stock prediction in similar areas.

The purpose of this study was to evaluate the partitioning of individual dry aboveground biomass in Cryptomeria japonica trees, as on its compartments as well as in the vertical profile, and examine whether the Pipe Model Theory, which states a rule between the plant organs, applies to the present case. Data were collected in a plantation established in 1984 in Rio Negro -PR. Twenty representative trees of the population distributed by diameter class were felled and weighed in the field, and their dry biomass were analyzed according to horizontal layers of 5 m wide in the following biomass compartments: sapwood, heartwood, bark, branches and foliage. Biomass is mostly composed by the stem (73.67%). In the wood, 41.66% of the biomass corresponds to sapwood, 26.66% to heartwood and 5.35% to bark. The canopy accounts for 26.33% of the dry biomass, which is represented at 13.75% by branches and 12.58% by foliage. In the first five meters tree biomass is comprised exclusively of wood and bark. From 5 m crown begins to have participation in biomass, becoming the major fraction from 15 m and above in the vertical profile. The partitioning of biomass in heartwood decreases along the vertical profile of the tree, i.e., it is largest at the base and smaller in the lower stratum. This study indicates that the Pipe Model Theory applies to the Cryptomeria japonica forest stand.Additional keywords: bole; crown; heartwood; japanese cedar; sapwood. ResumoEste estudo objetivou avaliar a partição da biomassa aérea seca em árvores de Cryptomeria japonica, tanto em compartimentos como no perfil vertical, e examinar se a Teoria do Modelo do Cano (Pipe Model Theory), que estabelece uma regra de proporção entre os órgãos da planta, aplica-se ao caso. Os dados foram coletados em um plantio estabelecido em 1984, no município de Rio Negro -PR. Vinte árvores representativas do povoamento distribuídas por classe diamétrica foram derrubadas e pesadas em campo, e suas biomassas secas foram analisadas segundo camadas horizontais de 5 m de amplitude, nos compartimentos: alburno, cerne, casca, galhos e folhas. A biomassa é constituída principalmente pelo fuste (73,67%). No lenho, 41,66% da biomassa correspondem ao alburno, 26,66% ao cerne e 5,35% à casca. A copa compreende 26,33% da biomassa aérea seca, sendo representada por 13,75% de galhos e 12,58% pelas folhas. Nos primeiros cinco metros da árvore, a biomassa é constituída exclusivamente de lenho e casca. A partir de 5 m, a biomassa da copa começa a ter participação, vindo a ter maior fração a partir dos 15 m do perfil vertical do povoamento. A participação do cerne na biomassa decresce ao longo do perfil vertical das árvores, ou seja, é maior na base e menor nas porções mais altas. Este estudo indica que a Teoria do Modelo do Cano se aplica ao povoamento florestal de Cryptomeria japonica.

This study was conducted to evaluate stand density-specific and generalized allometric equations, and biomass expansion factors (BEFs) for two stand densities (high density of 47-year-old: 667 tree·ha ) of Cryptomeria japonica plantations in Namhae-gun, located in the southern Korea. Biomass in each tree component, i.e. foliage, branch, and stem, was quantified by destructive tree harvesting. Allometric regression equations of each tree component were significant (P<0.05) with diameter at breast height (DBH) accounting for 80-96% of the variation except for branch biomass in high density or foliage and cone biomass in low density. Generalized allometric equations can be used to estimate the biomass of C. japonica plantations because the slopes of allometric equations were not significantly different by the stand density. The biomass expansion factors (BEFs) were significantly lower in the high stand density (1.33) than in the low stand density (1.50). The results indicate that BEFs were affected by different stand density, while allometric equations were little related to the stand density.
