CASTILLO-ARGUERO, Silvia; MARTINEZ-OREA, Yuriana  e  BARAJAS-GUZMAN, Guadalupe. Establishment of three tree species in the Magdalena river basin, México. Bot. sci [online]. 2014, vol.92, n.2, pp.309-317. ISSN 2007-4476.

Survival and growth of three tree species were evaluated under different treatments of mycorrhizal inoculation (Quercus rugosa), and plant cover (Abies religiosa and Pinus hartwegii), with the aim to recommend treatments for restoration and forest management in the Magdalena river basin. Survival and stem height and diameter were measured for one year (August 2006 to August 2007). The lowest survival percentages were recorded for A. religiosa and P. hartwegii in the treatment without vegetation. The highest survival values for Q. rugosa corresponded to plants inoculated with mycorrhizae. Moreover, the inoculated Q. rugosa seedlings reached the highest height values when compared to those without mycorrhizae. The treatments proved to be successful for the three tree species; therefore, we recommend them for a reforestation plan in each vegetation type in the Magdalena river basin.
