Protocolo eficiente para aumentar el porcentaje de prendimiento en injertos de Pinus greggii Engelm. var. australis Donahue et López

Abstract: Introduction: Grafted plants of conifers are used in the establishment of clonal seed orchards, but with the methodology currently used, unsatisfactory results are reported. Objective: To compare grafting and growth of Pinus greggii var. australis scion from nursery and field stock plants grafted on four rootstocks. Materials and methods: Scions of P. greggii Engelm. var. australis Donahue et López, collected from nursery stock plants (NSSP) and field trees (FSSP), were divided into terminal bud and basal segm… Show more

“…For example, Crecente Campo and Fernández Lorenzo (2008) reported grafting success rate of 27 % in Q. robur L. with field scions (first cycle) and 69 % to 95 % between the second and tenth grafting cycles. This is possible because there is greater control of mother plants in the nursery through pruning, irrigation, and fertilization to generate scions with desirable characteristics (Castro-Garibay et al, 2022).…”

“…Del 70 al 97 % de las plantas madre a partir de injerto formaron brotes, a pesar de que las púas injertadas provienen de árboles de 11 y 15 años de edad. En P. greggii se reportó la inducción de brotes en plantas injertadas con púas de árboles de 14 años (Castro-Garibay et al, 2022), pero la información es escasa sobre el manejo de plantas madre a partir de especies de pino adultos.…”

“…La capacidad para formar raíces tiende a disminuir con la edad debido al aumento de inhibidores del enraizamiento (Inoti et al, 2017). Se ha demostrado que se producen brotes más vigorosos y menos lignificados de plantas madre injertadas de árboles de P. greggii de 14 años de edad (Castro-Garibay et al, 2022); por ello, se esperaba que al injertar las púas de árboles adultos de P. patula sobre patrones jóvenes se pudieran inducir características juveniles como la capacidad de desarrollar raíces adventicias (Vidoy-Mercado et al, 2021); sin embargo, esto no sucedió.…”
