APARICIO-RENTERIA, Armando; JUAREZ-CERRILLO, Sergio Francisco y SANCHEZ-VELASQUEZ, Lázaro Rafael. Propagation by rooting of cuttings and conservation of extinct plus trees of Pinus patula from the north of Veracruz, Mexico. Madera bosques [online]. 2014, vol.20, n.1, pp.85-96. ISSN 2448-7597.
As a result of the use of a seed lot collected in March 1995, the germination percentage, the seedling growth of progeny through a growth curves model, as well as production sprouts and rooting cuttings ability were evaluated under a design of four blocks completely randomized, derived from 224 hedges of 28 extinct plus-trees from three populations of Pinus patula, grown in plastic bags (large and small). The germination percentage results were significantly different among the three populations, resulting higher in individuals from the Canalejas Otates area. A pattern defined by two phases of seasonal increase, one in autumn-winter and other in spring-summer was observed during the period of initial progeny growth. Variable responses were obtained in the production ability of sprouts due to origin population, size of bag and the experimental design used in the hedges growing. Finally, the rooting percentage was not statistically different when compared between the three populations, however, the cuttings derived from hedges grown in small bags showed a significant effect at 95% confidence with respect to those grown in large bags. This work is the first report of rooting Pinus patula cuttings published in Mexico.
