Growth and Frost Damage Variation Among Pinus Pseudostrobus, P. Montezumae, and P. Hartwegii Tested in Michoacan, Mexico

Viveros-Viveros, H., Saenz-Romero, C., Lopez-Upton, J., and Vargas- Hernandez, J. J. Forest Ecology and Management 253:81-88. 2007.

To study the variation in growth traits, survival, and frost damage between four taxa, Pinus pseudostrobus typical (represented by four provenances) and its variety P pseudostrobus var. apulcensis (two provenances), Pinus montezumae (two provenances) and Pinus hartwegii (one provenance), seeds of stands of natural distribution were obtained in the States of Michoacan, Puebla, Hidalgo and Veracruz, Mexico. Provenances were evaluated at two field sites located in forests of the Native Indian Community of Nuevo San Juan Parangaricutiro, Michoacan, at contrasting altitudes of 2200 and 2800 m. Evaluations made when seedlings were between 15 and 27 months old, indicate that there were large differences in initial growth and in frost damage between the taxa: typical P. pseudostrobus was the species with the largest growth although also the one of the largest percentage of frost damage; P. pseudostrobus var. apulcensis shows both intermediate total height and frost damage with respect to typical variety and to P. montezumae and P. hartwegii. Height growth of P. montezumae and P. hartwegii was lower than the growth of typical P. pseudostrobus and the apulcensis variety, although they presented the lowest percentage of frost damages.
