“…The interactions between rootstock and scion are highly complex, but increasing investigations in this field have recently shed considerable light on the biological mechanisms involved (Goldschmidt, 2014; Wang et al, 2016). It is widely accepted that metabolic substances could be transferred from one grafting partner to the other, including signaling molecules that may cause large biological effects.…”

Vegetable Grafting: The Implications of a Growing Agronomic Imperative for Vegetable Fruit Quality and Nutritive Value

Grafting has become an imperative for intensive vegetable production since chlorofluorocarbon-based soil fumigants were banned from use on grounds of environmental protection. Compelled by this development, research into rootstock–scion interaction has broadened the potential applications of grafting in the vegetable industry beyond aspects of soil phytopathology. Grafting has been increasingly tapped for cultivation under adverse environs posing abiotic and biotic stresses to vegetable crops, thus enabling expansion of commercial production onto otherwise under-exploited land. Vigorous rootstocks have been employed not only in the open field but also under protected cultivation where increase in productivity improves distribution of infrastructural and energy costs. Applications of grafting have expanded mainly in two families: the Cucurbitaceae and the Solanaceae, both of which comprise major vegetable crops. As the main drives behind the expansion of vegetable grafting have been the resistance to soilborne pathogens, tolerance to abiotic stresses and increase in yields, rootstock selection and breeding have accordingly conformed to the prevailing demand for improving productivity, arguably at the expense of fruit quality. It is, however, compelling to assess the qualitative implications of this growing agronomic practice for human nutrition. Problems of impaired vegetable fruit quality have not infrequently been associated with the practice of grafting. Accordingly, the aim of the current review is to reassess how the practice of grafting and the prevalence of particular types of commercial rootstocks influence vegetable fruit quality and, partly, storability. Physical, sensorial and bioactive aspects of quality are examined with respect to grafting for watermelon, melon, cucumber, tomato, eggplant, and pepper. The physiological mechanisms at play which mediate rootstock effects on scion performance are discussed in interpreting the implications of grafting for the configuration of vegetable fruit physicochemical quality and nutritive value.

“…The cells at the graft interface are capable of detecting the presence of the non-self grafting partner, which may induce an immune-type response (Cookson andOllat, 2013 Cookson et al, 2014 ; ). However, some studies revealed that plant grafting induced phenotypic variation in anatomy and morphology ( ; Wang et al, 2017Reig et al, 2018. Endogenous factors have been found to move across the graft union, which is the most convincing explanation for how phenotypic changes are induced by grafts.…”

“…A decisive factor in the failure of grafts is incompatibility, which refers to the lack of union between stock and scion, which affects the growth and productivity of the plants, and may even lead to their death [15][16][17].…”

When performing grafts, it is thought that by using plants of the same species the engraftment rate will be high; when the above is not fulfilled, the grafter, type of graft or the origin of the scions is blamed, but the anatomy of the parts forming the graft is not considered. The aim of this study was to evaluate the anatomy of four pine species used as rootstock and scion to define which species to use as rootstock based on cambium shape and bark thickness. Before grafting, 2-cm stem fractions were cut from plants that were used as rootstocks and scions. The evaluated species were Pinus patula, P. greggii, P. leiophylla and P. teocote. Cuts of 10 μm in thickness were made to determine bark and xylem thickness. Photographs were also taken with a photomicroscope to observe the "shape" of the vascular cambium. The experimental design was completely randomized with a 4x2 factorial arrangement, using 12 measurements as the sample size with four replicates. P. patula had greater bark thickness, while P. leiophylla obtained the greatest xylem thickness. In the images of the anatomical cuts, it was determined that the vascular cambium is continuous for all the species both in rootstock and in scions, but it is only circular in the P. teocote and P. leiophylla rootstocks, and the P. leiophylla scions did not present this feature. Based on the anatomy of the cambium, P. greggii, P. patula and P. teocote scions have greater possibilities of engraftment if they are grafted onto P. teocote and P. leiophylla because the cambium is circular. Tissue anatomy is one of the areas that must be known before making grafts in order to make appropriate decisions regarding the materials to be used.
