BARRERA RAMIREZ, Rubén; LOPEZ AGUILLON, Ricardo  e  MUNOZ FLORES, Hipólito Jesús. Survival and growth of Pinus pseudostrobus Lindl. and Pinus montezumae Lamb. on different planting dates. Rev. mex. de cienc. forestales [online]. 2018, vol.9, n.50, pp.323-341. ISSN 2007-1132.

Mortality in forest plantations for restoration purposes in the last decade (2007 to 2017) has varied from 40 to 60 % per year after established at the national level. The survival and development of pine and broad-leaved species have been affected by the combined effect of the date of planting, the preparation of the land and the quality of the plant, in addition to its late introduction. The objective of the study here described was to assess the survival, development and initial growth of Pinus pseudostrobus and Pinus montezumae established on different planting dates in the Comunidad Indígena de Nuevo San Juan Parangaricutiro, Michoacán. The plantation was established in 2013 and was replicated in 2015 under a randomized complete block design, with five planting dates (treatments) from July 1st to August 30th and each treatment with four replications. During three years, survival, growth in height and diameter at the base of the plant were evaluated; the analysis of variance showed significant differences (p≤0.05) in height and diameter. The plantation carried out on July 1st, 15th and 30th showed greater growth in both variables, in addition to 70 % survival in the two species. The success or failure of a plantation is the result of integrating a correct planting date, good plant quality and land preparation, together with favorable environmental conditions.
