Above-ground and needle biomass models on a fast-growing pine plantation in Oaxaca
A forest tree health can be accurately assessed by evaluating foliage biomass; even when it represents only 4% to 6% of the total tree biomass, it is the main driver of every major physiological processes.

| description | A forest tree health can be accurately assessed by evaluating foliage biomass; even when it represents only 4% to 6% of the total tree biomass, it is the main driver of every major physiological processes. This research was mainly focused on estimating accurately needle biomass at branch and tree level on fast growing trees of Pinus patula Schl. et Cham. Needle biomass per branch was estimated with a linear model, which used live branch basal area, live branch height, and crown section like independent variables.Above ground components were estimated with determination coefficients of 0,86, 0,92 and 0,88 for wood with bark, branches and needles. For the wood with bark model, diameter at breast height(DBH) and total tree height (HT) were used in a linear structure; total branch biomass was fitted with a non-linear model, using live crown diameter (LCD) and crown area (CA) while total needle biomass used LCD and HT on a non-linear model. The aboveground total biomass per tree was estimated with R2 = 0.87, using DBH and HT. At 14 years old, biomass partition was estimated to be 92,9%, 4,7% and 2,4% for wood with bark, branches and needles, respectively. |

El vigor de un árbol se puede evaluar a partir del follaje, que si bien representa de 4% a 6% de la biomasa total del árbol, es el componente principal para los procesos fisiológicos. El objetivo de este estudio fue estimar la biomasa de acículas en ramas individuales y árbol completo, y ajustar modelos de partición de biomasa aérea en árboles plantados de Pinus patula Schl. et Cham. La biomasa de acículas por rama se estimó con un modelo lineal, que empleó área basal de rama viva, altura de rama y el seccionamiento de copa como variables independientes. La biomasa de los componentes aéreos se estimó con coeficientes de determinación de 0,86; 0,92 y 0,88; para madera con corteza, ramas y acículas, respectivamente. Para madera con corteza se utilizó el diámetro normal (DN) y altura de árbol (AT) en un modelo lineal; la biomasa de ramas y follaje con ecuaciones no lineales que se basaron en el diámetro de copa viva (DCV) y área de copa para ramas; y DCV y AT para la biomasa de follaje. La biomasa total aérea por árbol se estimó con un R2 = 0,87; utilizando DN y AT. La biomasa a una edad de 14 años se distribuyó en 92,9%; 4,7% y 2,4% para madera, ramas y follaje, respectivamente.
