“…Rosier et al (2005) reported that the Abies fraseri scions from the lower zone of the crown were better for achieving the propagation of this species by rooting stem cuttings. Although grafts and cuttings are different vegetative propagation techniques, there are species like Pinus leiophylla that have been propagated by both methods, and some of the factors that have influenced their success are similar (Cuevas-Cruz, 2014;Cuevas-Cruz et al, 2015). The graft variables of the scions and rootstocks showed no significant effects on the probability of graft death in this study, as the stepwise regression revealed that none of the graft variables significantly affected graft survival (Table 2).…”

Grafting is one of the most widely used methods for vegetative propagation, particularly for multiplying trees considered important, but there has been little research done on the effect of hybridization on grafts from the genus Pinus. Sometimes hybrids show the ability to reproduce and adapt efficiently to the environment. However, they reduce the genetic gain of seed orchards. The objective in this research was to evaluate the effect of scion grafts from pure species donor Pinus engelmannii Carr. and from putative hybrid trees P. engelmannii. x P. arizonica Engelm., grafted on rootstocks of pure species Pinus engelmannii, along with the effect of the position of the scion in the donor tree crown (upper third and middle third). The scions were collected from three pure species trees and three hybrids. In each tree, 20 scions were collected from each third of the crown evaluated. 120 side-veneer grafts were made at the beginning of spring (March) 2018. Variance analyses were performed to evaluate the treatments and adjustments of the Logit and Weibull models to obtain the probability of graft survival. Significant differences were found between the origins of scions (p ≤ 0.0083, after Bonferroni correction), showing grafts with hybrid tree scions taking hold better. In addition, the probability of survival at five months after grafting with hybrid tree scions was greater (p ≤ 0.0001) than in grafts with pure-species tree scions (Logit model), which coincides with the results of the Weibull model, which indicated that the probability of graft death with pure species donor tree scions is greater than for grafts with hybrid scions. There were no significant differences regarding the position of the scion in the donor tree crown.

“…También menciona, que cuando el tejido pierde esta característica de competencia, el flujo polar de auxinas endógenas hacia el sitio de enraizamiento puede ser inhibido y afectar el proceso de inducción de raíces. Por lo que la aplicación de auxinas exógenas es necesaria para mejorar la respuesta al enraizamiento de las estacas de las especies de pino, ya que en ausencia de auxinas exógenas el porcentaje de enraizamiento es bajo (Cuevas-Cruz et al 2015, Rivera et al 2016, Riov et al 2020.…”

The limited seed production of Pinus hartwegii Lidl. requires the use of vegetative propagation techniques to produce plants for reforestation of the high mountain ecosystems. Nothing about vegetative propagation of the species has been done to our knowledge, therefore its ability to root propagules is, so far, unknown. In this study, the rooting of cuttings from three populations of P. hartwegii was evaluated, testing three treatments of Indole Butyric Acid (IBA, Radix®) (0, 5,000 and 10,000 ppm). The experiment was established in rooting chambers under a randomized four-block design with factorial arrangement. The rooted cuttings were transplanted and kept in a greenhouse. Survival, number of rooted cuttings, length and number of primary and secondary roots were evaluated after 12 weeks. Regardless of the auxin treatment, high percentages of rooting were observed in the cuttings. The auxin in 5,000 ppm amplified and improved the response to rooting (96.6 %); while the concentration of 10,000 ppm caused toxicity, which was reflected in the lower survival of the cuttings (63.5 %). The cuttings of the three populations showed high percentages of survival (> 80 %) and rooting (> 67 %); although without significant differences among them. A hundred percent of the rooted cuttings survived transplant. Massive multiplication through cuttings rooting is feasible for P. hartwegii, regardless of the genotype. With the application of exogenous auxins (5,000 ppm) the regeneration and development of roots was favored.
