“…Other tomato rootstocks have shown efficacy worldwide against bacterial wilt (11,24,25,30,39) but little information is available regarding the specific rootstocks utilized in those trials and most of the rootstocks are not commercially available for growers in the United States. In a recent preliminary report from the Eastern shore of Virginia (10), RST-04-105-T performed poorly, similarly to the Henderson County trial in this report but opposite to the Sampson and Jackson County trials.…”

Rivard, C. L., O'Connell, S., Peet, M. M., Welker, R. M., and Louws, F. J. 2012. Grafting tomato to manage bacterial wilt caused by Ralstonia solanacearum in the southeastern United States. Plant Dis. 96:973-978.Bacterial wilt, caused by Ralstonia solanacearum, can result in severe losses to tomato (Solanum lycopersicum) growers in the southeastern United States, and grafting with resistant rootstocks may be an effective strategy for managing this disease. However, R. solanacearum populations maintain considerable diversity, and little information is known regarding the efficacy of commercially available rootstocks to reduce bacterial wilt incidence and subsequent crop loss in the United States. In this study, tomato plants grafted onto 'Dai Honmei' and 'RST-04-105-T' rootstocks had significantly lower area under the disease progress curve (AUDPC) values compared with nongrafted plants (P < 0.05). Across three locations in North Carolina, final bacterial wilt incidence for non-and self-grafted plants was 82 ± 14 to 100%. In contrast, bacterial wilt incidence for the grafted plants was 0 to 65 ± 21%. Final bacterial wilt incidence of plants grafted with Dai Honmei rootstock was 0 and 13 ± 3% at two locations in western North Carolina but 50 ± 3% at a third site in eastern North Carolina. Similarly, grafting onto RST-04-105-T rootstock significantly reduced AUDPC values at two of the three locations (P < 0.05) compared with that of the nongrafted plants, but performed poorly at the third site. Total fruit yields were significantly increased by grafting onto resistant rootstocks at all three sites (P < 0.05). Regression analyses indicated that yield was significantly negatively correlated with bacterial wilt AUDPC values (R 2 was 0.4048 to 0.8034), and the use of resistant rootstocks enabled economically viable tomato production in soils naturally infested with R. solanacearum.

“…Grafting has been utilized to manage bacterial wilt in tomato crops worldwide (11,24,25,30,39), and has been proposed recently in the United States for open-field and high-tunnel production (22,33). Breeding lines CRA 66 and Hawaii 7996 were found to significantly reduce bacterial wilt incidence in naturally infested soils in North Carolina (33).…”

“…To overcome some of these hurdles, farmers rely on grafting technique, which consists in bonding parts of two plants by means of tissue regeneration developing a single plant (PEIL, 2003;CARDOSO et al, 2006;LOOS;CALIMAN;SILVA, 2009;SIRTOLI et al, 2011). Such tool make use of root systems (rootstocks) that are resistant, enabling control of diseases and pests related to the soil (LIN et al, 2008;RIVARD et al, 2012;GILARDI;GULLINO;GARIBALDI, 2013).…”

-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.Keywords: Solanum lycopersicum.

PEGAMENTO DE ENXERTOS DE TOMATEIRO EM DIFERENTES SOLANÁCEASRESUMO -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...

“…Grafting has recently been gaining popularity in the United States, partly as a result of the loss of methyl bromide and the increased restrictions of using soil fumigants. Several studies have demonstrated the effectiveness of grafting to manage bacterial wilt in tomato but all have used open-pollinated breeding lines that are not widely available (Lin et al, 2008;Rivard and Louws, 2008). The level of bacterial wilt resistance in available hybrid lines is unknown.…”

Seven hybrid tomato rootstocks with possible resistance to bacterial wilt caused by Ralstonia solanacearum and a known resistant cultivar were tested as grafting rootstocks to impart resistance to a bacterial wilt-susceptible cultivar, BHN 602. Greenhouse studies showed resistance of all the rootstocks to bacterial wilt. The disease incidence and yield of ‘BHN 602’ grafted to these rootstocks were evaluated in open-field tomato production in Florida and Virginia over four seasons. Significant differences in bacterial wilt incidence were observed between grafted entries in three of the four trials. In these three trials, grafted entries consistently exhibited the least bacterial wilt incidence compared with the controls; the self-graft, and non-grafted entries. Over all the trials, tomato plants grafted onto ‘Cheong Gang’, ‘BHN 1054’, and ‘BHN 998’ displayed the least bacterial wilt incidence. Rootstocks had a significant effect on total marketable yield in all the trials with certain grafted entries yielding significantly greater than non-grafted ‘BHN 602’. Field studies show that grafting holds promise for decreasing the impact of bacterial wilt on tomato cultivars as well as increasing the overall productivity of tomato cultivars.
