| Abstract | • Allometry of sapwood/heartwood is essential for understanding tree growth, water transport and carbon allocation, timber production and use, but such an allometry is lacking for Chinese temperate tree species. • We studied the allometry and development of heartwood and sapwood for seven Chinese temperate tree species: Korean pine (Pinus koraiensis Sieb. et Zucc), Dahurian larch (Larix gmelinii Rupr.), Japanese elm (Ulmus davidiana Planch var. japonica (Rehd.) Nakai), Manchurian ash (Fraxinus mandshurica Rupr.), Manchurian walnut (Juglans mandshurica Maxim.), Amur cork-tree (Phellodendron amurense Rupr.), and Mongolian oak (Quercus mongolica Fisch.). • All heartwood parameters investigated, including heartwood radius (HR), heartwood formation rate (HFR), heartwood ring number (HRN), heartwood initiation age (HIA), and heartwood volume ratio (HVR), were positively correlated with tree cambial age (CA). The HR, sapwood width (SW), sapwood area (SA), heartwood and sapwood volumes were significantly related to stem diameter at breast height (DBH) or xylem diameter. There was a polynomial relationship between the sapwood ring longevity (SRL) and sapwood ring number (SRN). However, most of the allometric relationships were species-dependent. The hardwood formation patterns were different between coniferous and broadleaved tree species. A power function was suitable to scale SA from DBH, but the exponent varied from 1.32 for the larch to 2.19 for the cork-tree. • Our allometry provided a practical means to assess wood development and related physiology for the temperate tree species. • L’allométrie de l’aubier/bois de cœur est essentielle pour comprendre la croissance de l’arbre, le transport de l’eau et l’allocation, la production et l’usage du bois, mais cette allométrie est manquante pour les espèces d’arbres chinoises de milieu tempéré. • Nous avons étudié l’allométrie et le développement du bois de coeur et de l’aubier pour sept espèces d’arbres tempérées chinoises : le pin de Corée (Pinus koraiensis Sieb. et Zucc), le mélèze de Dahurie (Larix gmelinii Rupr.), l’orme du Japon (Ulmus davidiana Planch var. japonica (Rehd.) Nakai), le frêne de Mandchourie (Fraxinus mandshurica Rupr.), le noyer de Mandchourie (Juglans mandshurica Maxim.), le phellodendron de l’Amur (Phellodendron amurense Rupr.), et le chêne de Mongolie (Quercus mongolica Fisch.). • Les paramètres du bois de coeur étudiés sont le rayon (HR), le taux de formation (HFR), l’âge d’initiation (HIA) et le ratio du volume (HVR) : ils sont corrélés positivement à l’âge cambial (CA). Le rayon du bois de cœur (HR), la largeur d’aubier (SW), la surface d’aubier (SA), les volumes de bois de cœur et d’aubier sont significativement liés au diamètre à hauteur de poitrine (DBH). Il y a une relation polynomiale entre la durée de vie des cernes d’aubier (SRL) et le nombre de cernes (SRN). Cependant la plus part des relations allométriques dépendent des espèces. Le patron de formation du bois de cœur diffère entre résineux et feuillus. Une fonction puissance est adaptée pour calibrer les variations de SA à partir de DBH mais l’exposant varie de 1,32 pour le mélèze à 2,19 pour le phellodendron de l’Amur. • Pour les essences d’arbres tempérées, notre allométrie fournit un moyen pratique pour estimer le développement du bois en tenant compte de la physiologie qui y est associée. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
