“…Additionally, the grafted plants had a delay in their initial development of a few days, due to the practice of grafting, which changes the final plant morphology. Argericha & Smith (2019) observed the same behavior in their assays.…”

Grafting can be an ally in the vegetable’s soilless cultivation, being the objective of this work evaluate the growth and production, as well as to define the thermal sum and trophic limit of grafted and non-grafted tomato plants cultivated in substrate. The experiments were conducted in a protected environment in the city of Jaguari-RS, in two growing seasons in the years 2019 and 2020. Italian and Gaucho tomato cultivars were used, the rootstock was chosen for giving vigor and longevity to the plants. Yield data were obtained through weekly fruit harvesting, growth data through periodic collections of whole plants and the total biomass obtained at the end of the experiments. Grafted plants show greater vegetative growth regardless of the crop season; however, non-grafted plants are more productive in a growing cycle with restricted light and low temperatures. Grafted plants require a greater thermal sum to complete their phenological stages. The trophic limit for grafted and non-grafted plants of Italian and Gaucho tomato cultivars is 4.8 MJ/m2/day.

“…Tomato scions grafted on Protector and Superpro rootstocks significantly increased total and marketable fruit production of processing tomato compared to nongrafted tomato cultivars. 65 Grafted tomato scion and rootstock combinations were evaluated in commercial grower fields in California over 2 years. Although fruit yields increased 10% and 19% in 2016 and 2017 in grafted plants, grafting was not economically feasible.…”

Nematode and disease resistant rootstocks have been developed for many vegetable crops including tomato, eggplant, melon, watermelon, and cucumber and are being utilized by an increasing number of growers. Grafting commercially desirable vegetable scions on nematode and disease resistant rootstocks has been significantly stimulated by the need for an alternative to banned soil fumigation with methyl bromide, which had been the primary method for managing soil‐borne nematodes, diseases, and weeds. Rootstocks resistant to root‐knot nematodes (Meloidogyne spp.) and diseases including Fusarium wilt, Fusarium crown and root rot, Verticillium wilt, bacterial wilt, Southern blight, and sudden wilt have been developed and many are available commercially. New technologies such as transcriptomics, identification of differentially expressed genes, transgene rootstocks, and RNAi silencing are being used in the development of vegetable rootstocks which are resistant to pests, salt tolerant, and heat and cold tolerant. Overall, grafting has proven to be a successful and environmentally safe method for managing root‐knot nematodes and soil‐borne diseases by reducing infection, disease development, and inoculum build‐up in the soil, which is especially important for growth of healthy subsequent crops. © 2021 Society of Chemical Industry.
