RESUMO O presente trabalho teve como objetivo avaliar o pegamento de enxertia de tomateiro, em diferentes espécies de solanáceas e por diferentes métodos de enxertia. Foram produzidas para enxerto mudas de tomateiro da cultivar Santa Cruz Kada®. O delineamento experimental utilizado foi o inteiramente casualizado, com os tratamentos arranjados em esquema fatorial 9 x 2, avaliando-se como porta-enxerto: os acessos de minitomate 0224-53, RVTC 57, RVTC 20 e 6889-50 (Solanum lycopersicum L); as espécies silvestres de tomateiro Solanum habrochaites var hirsutum ‘PI-127826’ e Solanum pennellii ‘LA716’; duas outras espécies Solanum, cubiu (Solanum sessiliflorum) e fisales (Physalis peruviana); e o tomateiro cultivar Santa Cruz Kada® como testemunha (auto-enxertia), e avaliados dois métodos de enxertia: fenda cheia; e encostia. Aos quinze dias após a enxertia, as plantas foram avaliadas quanto ao: índice de pegamento de enxertia; comprimento de raiz; altura das plantas; número de folhas; área foliar; massa seca das raízes, do caule e das folhas; e relação massa seca da parte aérea/massa seca das raízes. Com base nos resultados obtidos, foi possível verificar que o índice de pegamento e o desenvolvimento vegetativo das plantas após a enxertia em tomateiro foi influenciado significativamente pela interação (porta-enxerto x método de enxertia). Dentre os porta-enxertos avaliados, todos podem ser recomendados, exceto o acesso de minitomate 6889-50 (S. lycopersicum L.) e a espécie S. pennellii. Para os porta-enxertos cubiu e fisales recomenda-se a utilização do método de enxertia por fenda cheia, e para os porta-enxertos acesso de (minitomate 0224-53, RVTC 57 e RVTC 20; e espécie S. habrochaites) o método de encostia. | ABSTRACT This paper aimed to assess tomato grafting on different solanaceous species through two grafting methods. Scions were cut from cultivar Santa Cruz Kada seedlings. A fully randomized experimental design was carried out with treatments in a 9 x 2 factorial scheme. As rootstocks, four accessions of mini-tomatoes (0224-53, RVTC 57, RVTC 20 and 6889-50 - Solanum lycopersicum L); two species of wild tomato (Solanum habrochaites var hirsutum ‘PI-127826’ and Solanum pennellii ‘LA716’); other two tomato species [Solanum, cocona (Solanum sessiliflorum) and physalis (Physalis peruviana)] and a control with cultivar Santa Cruz Kada (auto-graft) rootstocks were used. In addition, two grafting methods were evaluated full cleft and approach graft. Fifteen days after grafting, plants were assessed for graft-take percentage; root length; plant height; leaf number; foliar area; root, stem and leaf dry matter; and ratio between shoot and root dry matter. Based on the results, we may state rootstock and grafting interaction had effect on both graft -take rate and plant development. Overall, the studied plants should be recommended as rootstock, except for 6889-50 mini-tomato (S. lycopersicum L.) and S. pennellii. Full cleft grafting was most suitable for cocona and physalis, while the approach method showed better results for the mini-tomato accessions 0224-53, RVTC 57 and RVTC 20, as well as for S. habrochaites.

RESUMO O trabalho foi conduzido no campo experimental do Departamento de Tecnologia e Ciências Sociais (DTCS), Campus III, da Universidade do Estado da Bahia - UNEB, Juazeiro-BA. O delineamento experimental foi em blocos casualizados, com parcelas subsubdivididas, com quatro repetições, as parcelas compostas de três ambientes sombreados, tela de sombreamento cinza, tela de sombreamento vermelha, e tela de sombreamento azul, mais o tratamento controle, sem sombreamento, as subparcelas formadas por três cultivares de minitomates ("Sweet Million", "Red Sugar", e "Shani") e as sub-subparcelas constituída de sete épocas de amostragens das plantas. As características avaliadas foram: acúmulo de massa seca nas folhas; no caule; nas raízes; nos frutos e total, além do comprimento da parte aérea, comprimento da raiz, o número total de frutos e produtividade. Os resultados de análise de crescimento apresentaram acúmulo de massa seca nos diferentes órgãos das plantas de minitomates, para todos os tipos de ambientes e que o maior acúmulo de massa seca total ocorreu no ambiente com tela vermelha. Em todos os ambientes analisados, o dreno preferencial da planta foi o fruto, contudo, a cultivar Red Sugar acumulou maior massa seca nos outros órgãos da planta em comparação com as demais cultivares. A cultivar Red Sugar obteve a maior quantidade de frutos por planta, entretanto, quando avaliou-se a produtividade total, as cultivares Sweet Million e Shani não diferiram entre si, sendo, superiores aos valores obtidos para a cultivar Red Sugar. | ABSTRACT Our study was conducted in the experimental field of the Department of Technology and Social Sciences (DTCS) of the State University of Bahia - UNEB, Juazeiro-BA. The experimental design was comprised of randomized blocks, sub-subdivided in plots, with four replicates comprising the plots of three different shading methods, gray shading screen (GS), red shading screen (RS), and blue shading screen (BS), and the control treatment with no shading. The subplots comprised three mini-tomato cultivars (“Sweet Million”, “Red Sugar”, and “Shani”), and sub-subplots consisted of seven sampling times. The traits evaluated were: dry matter accumulation in leaves, stems, roots, and fruits, total dry matter, shoot length, root length, total number of fruits, and overall yield. The results of the growth analysis showed that dry matter accumulation in organs of mini tomatoes was similar in all treatments and that the highest total dry matter accumulation occurred under RS. In all treatments, fruit was the preferential drainage; however, the cultivar “Red Sugar” showed higher dry matter accumulation in other plant organs. “Red Sugar” also showed the highest number of fruits per plant; however, when we evaluated total productivity, “Sweet Million” and “Shani” showed similar, higher values than “Red Sugar”.
