摘要: The biomass, carbon and nitrogen storage in the single tree components (foliage, branch, crown, bark, stem total aboveground) of grey poplar (Populus × canescens) its distribution Eastern Anatolia (Van, Turkey) were determined modelled. storages not estimated at a stand level but based on trees. Regression models diameter breast height (DBH) (H) developed to estimate (C) (N) different 28 two main regression power function only DBH (Model 1) combination (D2H) 2). All models, except for those foliage components, biomass C N found be statistically significant (p < 0.001). partitioning aboveground foliage, branches stems was 0.7, 9, 17 73%, respectively. average concentrations ranged from 48 (foliage) 50% (bark, branch stem), while 0.35 (stem) 1.32% (foliage). Higher lower compared with cultivated poplars likely related natural site conditions, low soil and/or characteristics growth.
