VEGA, José D  and  MARTIARENA, Rodolfo. Aboveground carbon stocks in plantations of araucariaç (Araucaria angustifolia -Bert.- O. Ktze). Rev. cienc. tecnol. [online]. 2010, n.13. ISSN 1851-7587.

This work estimated the aboveground carbon stock in plantations of Araucaria angustifolia -Bert.- O. Ktze of different ages, located in the north of the province of Misiones. The aboveground biomass was determined by destructive sampling of trees of 1, 2, 3, 6, 20, 30 and 40 years of age, equations were adjusted to estimate the dry weight of the remaining trees of the plot and biomass and carbon were calculated in the whole plantation of exemplars of all the ages mentioned. The carbon of the total aboveground biomass is 0,04; 0,31; 1,3; 21,9; 56,2; 60,5 and 92,2 Mg.ha-1 for tree ages 1, 2, 3, 6, 20, 30 and 40, respectively.
