“…The authors attributed the success of top cleft grafts to a more rapid, stronger joining that allowed transport of water and nutrients to the scion. In conifer species satisfactory results have been obtained with both top cleft and side veneer grafting (Barrera-Ramírez et al, 2020;Pérez-Luna et al, 2020), although sideveneer grafting has been more frequently applied (Blada and Panea, 2011). The success of both techniques is related to the internal and external anatomy of the tissues at the joint between the scion and the rootstock (Castro-Garibay et al, 2017).…”

Grafting in species of Pinus is used to establish asexual seed orchards. Generally, grafting success is low, therefore, it is required to study the influencing factors. Such as the technique and the contact surface of the cambium that depends on the length of the cut on the scion and the rootstock. The objective of this study was to evaluate graft success, growth, and needle development on Pinus patula grafts as functions of the grafting technique and cutting length. It was expected that a specific combination of technique and cutting length would allow predicting the graft success. The techniques of top cleft, side-veneer and splice grafting were used with three cutting lengths (1.5, 2.0, and 2.5 cm) in a completely randomized design with factorial array. The data were analysed with an analysis of variance and treatment means were compared with the Tukey test (p ≤ 0.05). Sixty days after grafting, technique influenced success; top cleft grafting had the highest value (80%) but was not statistically different from side veneer grafting (73.3%). There was, however, statistical difference between top cleft and splice grafting (56.7%, p ≤ 0.05). There were no differences among the three cutting lengths in terms of the three variables evaluated. The effect of the interaction showed that top cleft and side veneer grafts with the cutting length of 1.5 cm expressed the greatest growth (32.4 and 32.2 mm, respectively); followed by side veneer grafting with the cutting length of 2.0 cm (30.4). The study demonstrated that the most viable techniques to increase grafting success in P. patula are the top cleft and side veneer techniques. Cutting length of the scion and the rootstock can be set within the range 1.5 to 2.5 cm

“…The grafting methods evaluated were the side veneer technique described by Muñoz et al (2013) andPérez-Luna et al (2019) and the top cleft technique described by Muñoz et al (2013). For each technique, two phenological stages of the buds were tested; half of the grafts were made with scion buds at the end of latency (grafted on January 18, 2019) and the other half were made with the scion buds at the beginning of the sprouting stage (grafted on February 21, 2019).…”

“…To calculate the hazard ratio for graft survival using the Cox's proportional hazards model, dummy variables, including censor variables (dead grafts), were also used, so that the coding for the dependent variables was the same as in the Weibull model. Further details on the use of this model to assess graft survival are given by Pérez-Luna et al (2019).…”

“…The success of commercial forest plantations depends on the use of high-quality genetic material, which can be obtained from asexual seed orchards ( Yuan et al, 2016 ; Stewart et al, 2016 ; Pérez-Luna et al, 2020a ). To establish this type of orchard, superior genotypes must first be multiplied, either by grafting, air layering, cutting or by in vitro propagation ( Iglesias, Prieto & Alarcón, 1996 ; Bonga, 2016 ).…”

“…Another widely used non-parametric survival model, especially in medical science, is the Cox's proportional hazards model-and the associated hazard ratio-which measures the risk of death of a group of individuals subjected to two or more treatments (Meira-Machado et al, 2013;Gandrud 2015). Pérez-Luna et al (2019) recently demonstrated the potential use of this model to study the effect of several factors on graft survival and suggested that these modelling techniques are widely applicable in forestry research.…”

Developing methods for successfully grafting forest species will be helpful for establishing asexual seed orchards and increasing the success of forest genetic improvement programs in Mexico. In this study we investigated the effects of two grafting techniques (side veneer and top cleft) and two phenological stages of the scion buds (end of latency and beginning of sprouting), in combination with other seven grafting variables, on the sprouting and survival of 120 intraspecific grafts of Pinus engelmannii Carr. The scions used for grafting were taken from a 5.5-year-old commercial forest plantation. The first grafting was performed on January 18 (buds at the end of dormancy) and the second on February 21 (buds at the beginning of sprouting). The data were examined by analysis of variance and a test of means and were fitted to two survival models (the Weibull’s accelerated failure time and the Cox’s proportional hazards model) and the respective hazard ratios were calculated. Survival was higher in the top cleft grafts made with buds at the end of latency, with 80% sprouting and an estimated average survival time of between 164 and 457 days after the end of the 6-month evaluation period. Four variables (grafting technique, phenological stage of the scion buds, scion diameter and rootstock height) significantly affected the risk of graft death in both survival models. Use of top cleft grafts with buds at the end of the latency stage, combined with scion diameters smaller than 11.4 mm and rootstock heights greater than 58.5 cm, was associated with a lower risk of death.
