Resumo: The experiment was conducted in the period between December 2010 and June 2011, at the Capão do Leão Campus of Universidade Federal of Pelotas. The study aimed to analyze the growth and physiological characteristics of the qualitative production of tomato grafted and ungrafted under a protected environment. The seedlings were produced by the method of cutting terminal and ungrafted in polystyrene trays. After the period of budding, the seedlings were transplanted to the greenhouse and evaluated for growth, assimilate partitioning, yield and fruit quality and randomized blocks. From the comparative analysis of growth, the plants grafted on the hybrid Kaguemusha® showed a higher accumulation of dry matter at the end of the cycle and net assimilation rate (Ea) for more than 2/3 of the crop cycle. The relative growth rate, net assimilation rate and Ra peaked in the early phase of the cycle, and decreasing from then until the end of the cycle regardless of treatment. Grafting resulted in higher early, dry matter content of fruits, average fruit weight, shoot/root ratio, harvest index and total phenols, however the grafted plants were less productive than those of ungrafted. It was also that of ungrafted plants had soluble solids content and total yield than the grafted, however the distribution of these classes had a higher percentage of unmarketable fruits compared plants subjected to grafting.

O trabalho teve por objetivo analisar as características fisiológicas de crescimento e as qualitativas produtivas do tomateiro enxertado e pé-franco em ambiente protegido. As mudas foram produzidas pelo método de estaca terminal e o pé-franco em bandejas de poliestireno expandido. Após o periodo da enxertia as mudas foram transplantadas para casa de vegetação, sendo realizadas avaliações de crescimento, partição de assimilados, produtividade e qualidade dos frutos em blocos casualizados. A partir da análise comparativa dos dados de crescimento, as plantas enxertadas sobre o híbrido Kaguemusha® apresentaram maior acumulo de matéria seca ao final do ciclo e taxa assimilatória líquida (Ea) superior durante 2/3 do ciclo de cultivo. As taxas de crescimento relativo, assimilatória líquida e de crescimento relativo de área foliar atingiram o pico na fase inicial do ciclo, sendo decrescentes a partir de então até o final do ciclo independente do tratamento. A enxertia resultou em maior precocidade, teor de matéria seca de frutos, massa média de frutos, razão parte aérea/raiz, e teor de fenóis totais, entretanto as plantas enxertadas foram menos produtivas que as de pé-franco. Verificou-se ainda que plantas de pé-franco apresentaram teor de sólidos solúveis totais e produção total de frutos superior as enxertadas, entretanto na distribuição destes em classes apresentou maior percentual de frutos não comerciais quando comparadas as plantas submetidas à enxertia.
