Zusammenfassung:ABSTRACT In this study were evaluated gas exchanges, fruit production and fruit quality of tomato Santa Cruz Kada grafted onto different species of the genus Solanum, using two grafting methods. For the grafted tomato cultivation, the authors used a randomized complete block design, in a 8x2 factorial scheme, evaluating eight rootstocks: accessions of mini tomatos (0224-5, RVTC 57, RVTC 20 and 6889-50); wild tomato species Solanum habrochaites var. hirsutum (PI-127826); Solanum pennellii (LA716); Solanum sessiliflorum (cubiu); and tomato cultivar Santa Cruz Kada (self-grafting, control), and two grafting methods {cleft grafting (FC) and approach grafting (EC)}. The authors verified a significant interaction between rootstock x grafting method. The S. pennellii rootstock provided the best results for physico-chemical characteristics, when grafted using the cleft method. However, the same method, along with cubiu rootstock, presented lower fruit production. Considering the gas exchange and productive characteristics, S. habrochaites as rootstock for tomato Santa Cruz provided the best results for photosynthetic yield and water use efficiency, and for the commercial fruit production characteristic, both grafting methods, and for the average mass of commercial fruits when grafted using FC, with about 5.03 kg/plant and 163.5 g/fruit, respectively. In relation to the grafting methods, the cleft showed to be the most suitable. RESUMO No presente trabalho teve-se como objetivo avaliar trocas gasosas, a produção e qualidade de frutos do tomateiro Santa Cruz Kada enxertado em diferentes espécies do gênero Solanum e por dois métodos de enxertia. Para o cultivo de tomateiro enxertado, foi utilizado delineamento experimental de blocos ao acaso, em esquema fatorial 8x2, avaliando-se oito porta-enxertos: acessos de mini tomates (0224-5, RVTC 57, RVTC 20 e 6889-50); espécies silvestres de tomateiro Solanum habrochaites var. hirsutum (PI-127826); Solanum pennellii (LA716); Solanum sessiliflorum (cubiu); e tomateiro cultivar Santa Cruz Kada (autoenxertia, testemunha), e dois métodos de enxertia {fenda cheia (FC) e encostia (EC)}. Verificou-se que para todas as características avaliadas, houve interação significativa entre porta-enxerto x método de enxertia. O porta-enxerto S. pennellii proporcionou os melhores resultados para as características físico-químicas, quando enxertado por meio do método de fenda cheia. No entanto, o mesmo, juntamente com o porta-enxerto cubiu, apr
