MONTERO SOLIS, Flor María et al. Initial growth of multi-purpose forest species in a livestock land at the north of Veracruz. Rev. mex. de cienc. forestales [online]. 2011, vol.2, n.3, pp.53-68. ISSN 2007-1132.

The initial growth in height and diameter was evaluated for seven multipurpose tree species in a livestock land of Tihuatlán, Veracruz, México, through three plantation designs with a proportion 6:3:1 and an arrangement "tres bolillo" with a distance of three meters between columns and 1.5 between lines to obtain a major covering of the species to investigate. The growth in height through the covariance model was significantly (p<0.0001) higher than the growth in diameter for all the species and during the time that were measured (330 days). The three species which had the higher growth rate in height were: Cordia dodecandra (0.14 cm day^-1), Tabebuia rosea (0.073 cm day^-1) and Guazuma ulmifolia (0.027 cm day^-1); whereas the higher growth rates in diameter were for: C. dodecandra y T. rosea (0.046 mm day^-1), Cedrela odorata (0.028 mm day^-1) and G. ulmifolia (0.023 mm día^-1). The effect of damage for withering (lost of the apical bud) only was significant (p<0.05) in height of Brosimum alicastrum (0.0024 cm day^-1, p<0.0202) y T. rosea (-0.051 cm day^-1, p<0.0001); however, in both species the damages could bear several atmospheric conditions (absence of precipitation and/or high temperatures) in some stage of their initial growth without to reach preventing their posterior growth. The survival was of 98.4 %.
