Growth and productivity characterization of young teak (Tectona grandis Linn f.) plantations and estimation of site index curves in the septentrional area of the Republic of Guatemala
In 2015 the teak (Tectona grandis Linn f.) plantations of Guatemala covered approximately 33 000 hectares, of which 80% are located in the septentrional northern region and, in order to characterize the evolution in terms of growth and development, data from a total of 248 permanent monitoring plots...

| description | In 2015 the teak (Tectona grandis Linn f.) plantations of Guatemala covered approximately 33 000 hectares, of which 80% are located in the septentrional northern region and, in order to characterize the evolution in terms of growth and development, data from a total of 248 permanent monitoring plots (in plantations established between 1998 and 2001 with measurements each year between 2004 and 2009) have been analyzed. The results show that, on average, 13,01% of the sites present high growth, 70,66% medium growth and 16,33% low growth. For the sites of medium to high growth, i.e., 83,67 %, the Site Index at a base age of 10 years that will be achieved will be between 19,13 m and 25,32 m, a mean annual increase in total height (MAIHTOT) of between 1,98 m yr-1 and 2,62 m yr-1, a mean annual increase in DBH (MAIDBH) of between 2,23 cm yr-1 and 2,82 cm yr-1 and productivity (MAIVOL) of 9,89 m3 yr-1 to 17,22 m3 yr-1. The sites that present low growth rates will reach a site index of 12,94 m, a MAIHTOT of 1,34 m yr-1, a MAIDBH of 1,65 cm yr-1 and a maximum productivity of 2,55 m3 yr-1. The analysis of variance showed significant differences with a p-value ≤ 0,001 in site index, MAIHTOT, MAIDBH, MAIBA and MAIVOL. The site index curves based on a modified growth model allowed the identification and definition of a land classification based on its productive capacity on site, and thus evidences the growth and development of teak in Guatemala. |

Para el 2015 en Guatemala las plantaciones de teca (Tectona grandis Linn f.) alcanzan aproximadamente 33 000 hectáreas, de las cuales 80% se ubican en la región septentrional. Para caracterizar estas plantaciones, su evolución en términos de crecimiento y desarrollo, se analizaron datos de un total de 248 parcelas permanentes de monitoreo establecidas entre 1998 y 2001 con mediciones efectuadas cada año entre el 2004 y 2009; encontrándose que en promedio 13,01% de los sitios presentan crecimientos altos, 70,66% crecimientos medios y 16,33% crecimientos bajos. Para sitios medios a altos, es decir en 83,67%, el índice de sitio a una edad base de diez años que alcanzará, será entre 19,13 m y 25,32 m, incremento medio anual de la altura total (IMAHTOT) entre 1,98 m año-1 y 2,62 m año-1, incremento medio anual del DAP (IMADAP) entre 2,23 cm año-1 y 2,82 cm año-1 y una productividad (IMAVol) desde 9,89 m3 año-1 hasta 17,22 m3 año-1. Entretanto, los sitios que presentan crecimientos bajos, alcanzarán un índice de sitio de 12,94 m, un IMAHTOT de 1,34 m año-1, IMADAP de 1,65 cm año-1 y una productividad máxima de 2,55 m3 año-1. El análisis de varianza mostró diferencias estadísticamente significativas con p-valor ≤ 0,001 en índice de sitio, IMAHTOT, IMADAP, IMAAB e IMAVol. Las curvas de índice de sitio basadas en un modelo de crecimiento modificado permitieron identificar y definir una clasificación de los terrenos en función de su capacidad productiva en sitio y así evidenciar el crecimiento y desarrollo de la teca en Guatemala.
