“…A positive compatibility between the rootstock and the scion is indicative of physiological changes due to cellular interactions between two genotypes (Kokalis- Burelle et al, 2009). In a study by Farias et al (2013), the same results were observed when grafting tomato on the rootstocks S. Gilo S. lycocarpum, S. stramonifolium, and S. viarum, obtaining positive compatibility (> 1) and indicating high-vigor rootstocks.…”

Atualmente, o tomate é uma das culturas mais cultivadas no mundo, com o maior valor econômico, aumentando sua demanda e, assim, sua expansão, produção e comercialização. A cultura do tomate é suscetível ao ataque de patógenos com consequências devastadoras no declínio da produtividade de 50 para 100%. Por esta razão, novos métodos de produção são propostos, como o uso de porta-enxertos selvagens, que possuem alta variabilidade genética e genes responsáveis pela resistência a fungos, bactérias, vírus e nematoides. O objetivo deste trabalho foi avaliar o efeito do enxerto de cultivares comerciais de tomateiro sobre genótipos de tomateiro em produtividade e qualidade de frutos. O experimento foi organizado em delineamento inteiramente casualizado com quatro repetições. A unidade experimental consistiu em quatro plantas, espaçadas a 0,9 m entre linhas (canais), 0,30 m entre linhas duplas e 0,4 m entre plantas. Os tratamentos consistiram da combinação dos seguintes fatores: três porta-enxertos promissores (IAC391, IAC426 e LA2076), dois enxertos comerciais (Calima e Torrano), dois métodos de enxertia (fenda e inglês simples) e dois controles comerciais não enxertados. Os componentes de rendimento, teor de sólidos solúveis, porcentagem de qualidade dos frutos e peso médio dos frutos foram avaliados. O IAC391 foi o porta-enxerto mais promissor, alcançando produções semelhantes às dos controles. O método de enxertia de fenda atingiu uma taxa de sucesso de 98,3%. O enxerto comercial Torrano se destacou por alcançar os maiores rendimentos.Palavras-chave: fenda; inglês simples; Torrano; Calima; porta enxerto. ABSTRACT RESUMODevelopment, production, and quality of 'Chonto' type tomato grafted on cherry tomato introductions 1 Currently, tomato is one of the most cultivated crops worldwide, with the highest economic value, increasing its demand and, thus, its expansion, production, and trade. The tomato crop is susceptible to attack of pathogens with devastating consequences on the decline in yields from 50 to 100%. For this reason, new production methods are proposed such as grafting in wild rootstocks, which have high genetic variability and genes responsible for resistance to fungi, bacteria, viruses, and nematodes. The aim of this study was to evaluate the effect of grafting commercial tomato cultivars onto cherry tomato genotypes on yield and fruit quality. The experiment was arranged in a completely randomized design with four replications. The experimental unit consisted of four plants. spaced at 0.9 m between rows (channels), 0.30 m between double rows, and 0.4 m between plants. The treatments consisted of the combination of the following factors: three promising rootstocks (IAC391, IAC426, and LA2076), two commercial scions (Calima and Torrano), two grafting methods (cleft and splice), and two ungrafted commercial controls. Yield components, soluble solids content, percentage of fruit quality, and average fruit weight were evaluated. IAC391 was the most promising rootstock, reaching productions similar to those of th...

“…The compatibility of tomato cv. IPA-6 (Farias et al, 2013) and cv. Santa Adélia (Simões et al, 2014) grafted onto S. stramonifolium and S. lycocarpum rootstocks was evaluated and higher yield and graft compatibility with tomato cultivars was obtained.…”

“…In the present work, we could find similar results, where seven accesses of S. stramonifolium showed multiple resistance, CNPH-19, CNPH-22, CNPH-23, CNPH-25, CNPH-120, CNPH-122 and CNPH-349, indicating that these accesses possess high potential to be used as resistant rootstocks to diseases in tomato grown in infested areas. According to Farias et al (2013) it is important to keep focusing on studies such as the present one, in order to select new tomato cultivars, compatible with wild Solanaceae rootstocks, which will help to control soil pathogens and increase tomato productivity. However, the knowledge about the genes involved in the resistance reactions and in the defense mechanisms involved in the interactions between accessions of S. stramonifolium and soil pathogens need to be elucidated.…”

Resistant rootstocks is one of the most effective method to control soilborne pathogens in tomato crops. Thus, this study was installed to evaluate the reaction of Solanum stramonifolium accesses to Fusarium oxysporum f. sp. lycopersici (Fol) races 2 and 3 and to Meloidogyne enterolobii (Me). The seedlings were grown in trays and inoculated separately with Fol races 2 and 3 at 50 days after planting by immersing the roots in the spore suspension (1×106 microconidia mL-1). Then, seedlings were transplanted in pots containing sterilized soil and kept in greenhouse conditions. To study the reaction of S. stramonifolium accesses to nematodes, we used 27-day old seedlings that were also planted in pots and inoculated with 6,000 eggs and second-stage juveniles in greenhouse conditions. The experiments were evaluated in the 34th day (Fol) and in the 64th day (Me) after inoculation. The experiment consisted of a randomized block design with five replications, where each plot consisted of one pot with three plants (Fol) and one pot with one plant (Me). We observed that the plants used as controls, susceptible to Fol races 2 and 3 and Me, presented 100% of incidence. All accesses were resistant to Fol race 2 and the accesses CNPH-19, CNPH-22, CNPH-23, CNPH-25, CNPH-120, CNPH-122 and CNPH-349 presented multiple resistance to pathogens, indicating great potential for using as resistant rootstock. The CNPH-24, CNPH-119, CNPH-121 and CNPH-336 accesses also presented resistance to nematode. However, they presented slight browning symptoms of vascular tissues when they were inoculated with Fol race 3. This symptom was also observed in the CNPH-21, CNPH-107 and CNPH-117 accesses. All other accesses were resistance to Fol race 3 and susceptible to Me.

“…Por isso, a produção e produtividade do tomate são baixas, necessitando de técnicas para alavancar o cultivo, visando reduzir as importações e gerar emprego e renda na região (GONÇALVES, 2012). Farias et al (2013) relatam que o cultivo de tomate orgânico enxertado com porta enxertos resistentes a doenças de solo atinge produtividades variando de 13,4 a 50,1 t ha -1 . O tomate exige grandes quantidades de insumos, que pode chegar a 15,9 t ha -1 , de fertilizantes, correspondendo a 12,1% do custo de produção.…”

Resumo: A importância alimentar do tomate orgânico aliado a sua baixa produção na Amazônia e a necessidade de baixo uso de insumos para seu cultivo ecológico o objetivo deste trabalho foi avaliar a produtividade de cultivares de tomate orgânico cultivado em campo e ambiente protegido com alto e baixo nível de insumos. Os experimentos foram conduzidos em ambiente protegido e campo, ambos no delineamento em blocos casualizados completos, em esquema de parcelas subdivididas 2 x 3, sendo a parcela principal composta por dois níveis de insumos e a subparcela pelas cultivares copa (Santa Kruz Kada, IPA 6 e Santa Clara), com cinco repetições de cinco plantas cada. As variáveis avaliadas foram: massa média de frutos total e comercial (g fruto -1), número de frutos total e comercial por planta, produtividade total e comercial de frutos (kg ha -1 ). A cultivar IPA 6 em cultivo protegido exigiu maior uso de insumos para aumentar a massa média de fruto total e comercial, produtividade total e comercial, em campo pode se utilizar baixo nível de insumo. O alto uso de insumos é necessário para aumentar a produtividade total e comercial para a cv. Santa Clara em cultivo à campo, ambiente que também necessita de alto uso de insumos para aumentar a massa média de fruto total e comercial a produtividade comercial da cultivar Santa Kruz. Palavras-chave: Lycopersicon esculentum; cultivo orgânico; cultivo protegido. Abstract:The importance of organic tomato feed associated with their low production in the Amazon and the need for low input to its ecological farming the objective of this study was to evaluate the productivity of organic tomato cultivars grown in field and greenhouse with high and low level inputs. The experiments were conducted under greenhouse and field conditions, both in randomized complete block design comprising plots subdivided into subplots. The plots encompassed of two levels of inputs, while the subplots contained the (Santa Kruz Kada, 6 and IPA Santa Clara), with five replicates of five plants each. The variables evaluated were: total fruit mass and marketable fruit mass (g fruit -1), number of total and marketable fruit per plant, total and marketable fruit yield (kg ha -1 ). The cultivar IPA 6 in greenhouse demanded greater use of inputs to increase the total and marketable fruit mass, total and marketable yield in field can be used for low level input. The high use of inputs is necessary to increase the total and marketable yield for cv. Santa Clara in the growing field, environment which also requires high use of inputs to increase the total and marketable fruit mass, marketable fruit yield of cultivar Santa Kruz.
