Exploring graft incompatibility markers: Intraspecific and interspecific grafts of tomato (Solanum lycopersicum L.)

Productive and physiological characteristics of tomato plants produced on different rootstocks

“…The greater TFM of ungrafted plants and with cherry tomato rootstock increases the economic return and is due to the use of the intact plant and a rootstock of the same species, with a high degree of kinship with the scion (Thomas et al, 2022). Tomato self-grafting and intraspecific grafts improved performance compared to interspecific ones due to plant physiological, biochemical and histological interactions (Babar et al, 2023).…”

“…Disease-resistant or disease-tolerant rootstocks (Fullana et al, 2023;Rabelo et al, 2018), important in integrated management, can reduce production costs and are agroecologically correct (Ito et al, 2014). Tomato grafting, on domesticated or wild cultivars or plant species (Farias et al, 2013), can improve disease and pest management (Garita et al, 2018(Garita et al, , 2019Sabatino et al, 2013) without causing environmental impacts compared to other traditional control methods (Doñas-Uclés et al, 2014), in addition to improving product quality (Loos et al, 2009).…”

“…The grafting involves a set of changes at the molecular and tissue level, at the graft interface, during the healing and union process (Loupit & Cookson, 2020;Williams et al, 2021). Incompatible morpho-physiological characteristics (Zeist et al, 2018) and the difficulty in obtaining rootstocks tolerant to the main edaphoclimatic problems hinder the adoption of this technique for tomato plants (Doñas-Uclés et al, 2014). Among commercial tomato plants, the 'Santa Clara' cultivar produces fruits belonging to the table segment of the Santa Cruz group, being the most produced and consumed cultivar and also a reference for inferences about the architecture of plants grown in the field (Gomes et al, 2023).…”
