MUNOZ FLORES, H. Jesús; CORIA AVALOS, Víctor M.; GARCIA SANCHEZ, J. Jesús  y  BALAM CHE, Manuel. Evaluación de una plantación de tres especies tropicales de rápido crecimiento en Nuevo Urecho, Michoacán. Rev. Cien. For. Mex [online]. 2009, vol.34, n.106, pp.61-87. ISSN 1405-3586.

In the state of Michoacan the Commercial Plantation Program began in 2003 and the most planted species are Pinus (69%), Cedrela odorata and Acrocarpus fraxinifolius (24%), Eucalyptus camaldulensis (5%) and 2% of native tropical species. Results about their adaptation and growth in different ecological conditions in the state are unknown. The objectives of this research were to assess the response in height growth, normal diameter and survival of Tectona grandis, Acrocarpus fraxinifolius and Gmelina arbórea, as well as to compare the annual mean increment with data from foreign countries. The plantation was established in December 2003 at Nuevo Urecho, Michoacan, where environmental conditions are: chromic vertisol soil, subhumid weather, 3% slope and an altitude of 514 m. A random block experimental design was applied, with three treatments and four replications. Each experimental unit was made up of 25 plants, which summed up 100 for each species. Environmental conditions of the place are: land preparation labor was done prior to the establishment of the plantation, and a fallow at 30 cm deep was done. Additional watering was applied during the dry season. Results showed significant differences in height and normal diameter among treatments after two years, but survival was not different. Gmelina arbórea was the species with the best response (6.82 cm in high), BHD of 10.81 cm and a survival percentage of 94.96. This species offers a good potential to develop a commercial plantation program in the dry tropic area of the state of Michoacán.
