RUIZ BLANDON, Bayron Alexander et al. Carbon storage and lignocellulosic characterization of commercial plantations of Tectona grandis L.f. in Mexico. Colomb. for. [online]. 2019, vol.22, n.2, pp.15-29. ISSN 0120-0739.  https://doi.org/10.14483/2256201x.13874.

Teak is an exotic plant introduced to Mexico for its wood value. The aim of this study was to quantify the carbon stored in the plant biomass and soil and to determine the wood lignocellulosic composition in 6-years-old teak plantations in the Nayarit state, Mexico. In three plantations, dendrometric and biomass information were collected from 75 trees, as well as litter layer and soil to determine their properties. The differences were significant (p≤0.0001) when comparing the plantation with the highest and lowest growth in DBH (54 %), height (51.3 %) and basal area (78.7 %) being the soils with the best pH (6.2); as well as, the aerial biomass yield (59.4 %), teak carbon (60.2 %), litter layer (30.3 %) and soil (41.9 %) per surface, without differences in lignocellular contents. It is recommended to study the roots and soil nutrients, since they condition the teak efficiency regarding the climate change.
