Organic production of tomatoes in the amazon region by plants grafted on wild Solanum rootstocks
subject: Agricultura orgânica, enxertia, produtividade
description: The production of organically grown tomatoes in the Amazonian region of Brazil is difficult due to inherent phytosanitary issues. The objectives of the present investigation were to evaluate the productivity of grafted tomato plants (Solanumlycopersicum cv. Santa Adélia) grown organically in Rio Branco, Acre, Brazil, and to assess scion/rootstock compatibility under organic growth conditions. The Solanum species employed as rootstocks were S. gilo (jiló), S. lycocarpum (jurubebão), S. stramonifolium (jurubeba vermelha) and S. viarum (joá), while the susceptible S.lycopersicum cultivar Santa Adélia was the scion. Ungrafted tomato plants and tomato grafted on tomato rootstock were employed as controls. The experiment was arranged in a completely randomized block design with six treatments and five repetitions of five plants each. Data were submitted to analysis of variance and the significance of differences between treatments were determined using the Tukey test (P
