FUENTE SOLIS, Ana Marissa de la et al. Survival and growth of Pinus cembroides Zucc. in Northeastern Mexico. Rev. mex. de cienc. forestales [online]. 2024, vol.15, n.86, pp.167-177.  Epub 03-Mar-2025. ISSN 2007-1132.  https://doi.org/10.29298/rmcf.v15i86.1466.

The evaluation of the survival and growth of a Pinus cembroides plantation was carried out in the La Tapona ejido, Galeana municipality, state of Nuevo Leon, with the objective of evaluating the effect of individual terraces and ditches in basal diameter, total height, and crown diameter of a 10-year-old plantation. 13 transects (contour lines) for each of the treatments (26 in total) were evaluated using a systematic random sampling design. From each of the transects, information was taken from all individuals, including diameter at 10 cm from the base of the trunk (cm), total height (m) and crown diameter (m). To determine whether there were significant differences in the survival of specie in relation to the different treatments (individual terraces and ditches), an analysis of variance was performed using Student's t-test and the Mann-Whitney U-test for height, diameter at 10 cm and crown diameter. The results indicate an overall average survival of 52.69 %, while in blind pits it was 53.71 %, and individual terraces it was 51.68 %. However, the tests showed that there were no significant differences in growth of individuals within conservation practices.
