RIOS-SAUCEDO, Julio Cesar et al. Allometric equations commonly used for estimating shoot biomass in short-rotation wood energy species: a review. Rev. Chapingo ser. cienc. for. ambient [online]. 2016, vol.22, n.2, pp.193-202. ISSN 2007-4018.  https://doi.org/10.5154/r.rchscfa.2015.05.022.

Wood energy crops in a short rotation coppice (SRC) commonly consist of single-stem tree individuals in the first short cycle, but from the second cycle onward numerous sprouts or shoots emerge from each stump, resulting in interesting challenges when estimating their biomass. The aim of this study was to identify species, rotation length and types of allometric models used to estimate biomass in SRC through a detailed search of the scientific journals in the Scopus and Web of Science databases. Among the most commonly used models to estimate biomass (y) is the typical exponential model, which has the following predictors: diameter at breast height (D) ($y=b_0{D}^{b_1}$), stem basal diameter (Db) ($y=b_0{Db}^{b_1}$) and the combination of diameter at breast height squared by total height (D2H) (y = b0 + b1D2H), stands out. The genera with the largest number of different models were Populus, Salix and Eucalyptus. The first two are the most studied. The rotation length used in the crops studied ranged from one to 15 years.
