Abstract
Grafting can either favor or limit growth, productivity, and fruit quality; therefore, choosing the right combination of scion and rootstock is essential for the plant’s performance. This study aimed to evaluate the growth and production of tomato hybrids from the salad group grafted onto different rootstock hybrids. Two experiments were conducted using a combination of the salad-type hybrids Valerim and Dylla with five rootstock hybrids: Shield RZ, Green Rise, Green Power, Shincheonggang, and Guardian. The experimental design was randomized blocks, with seven treatments and four replications per treatment. The treatments consisted of combining the rootstocks with each graft (Valerim and Dylla), in addition to autografting the two grafts and the non-grafted seedlings, that is, the two grafts without grafting. Non-grafted seedlings were defined as the control treatment. The interaction with rootstocks or autografting influences the stem growth and diameter up to 30 days after transplantation of the hybrids Valerim and Dylla. However, the rootstocks evaluated did not affect development or compatibility. For the yield parameters, the combinations Valerim/Valerim, Shield RZ, Guardian, and Green Rise presented positive effects. Grafting did not influence the yield parameters of the Dylla hybrid. Likewise, grafting did not influence the physicochemical characteristics of the fruits of the two hybrids, Valerim and Dylla.
