Resumo
O objetivo deste trabalho foi desenvolver um método de produção de mudas de tomateiro a partir de estacas laterais enraizadas em hidroponia. Foram realizados três experimentos. Nos experimentos 1 e 2, as estacas foram enraizadas em espuma fenólica e em solução nutritiva, respectivamente, e os tratamentos representaram as posições de retirada das estacas das axilas das folhas de 1 a 5 da base para o ápice. No experimento 3, estacas enraizadas nos experimentos 1 e 2, foram transplantadas para vasos contendo solução nutritiva e cultivadas até a produção do primeiro cacho. Com relação à massa de matéria fresca das raízes, pontos de interseção da raiz, massa de matéria seca dos caules e das folhas, comprimento de raízes, área foliar, número de folhas e diâmetro do caule, nos experimentos 1 e 2, não foi observada diferença estatística significativa entre os tratamentos 1, 2, 3 e 4. No experimento 3, apenas o diâmetro dos frutos apresentou diferença estatística entre os tratamentos. O tratamento 3 foi superior ao 5, e os tratamentos 1, 2, 3 e 4 foram semelhantes entre si. Em sistema hidropônico, podem ser produzidas mudas de tomate a partir de estacas, utilizando-se espuma fenólica ou solução nutritiva como meio de enraizamento.
The objective of this work was to develop a method to produce tomato seedlings through rooted cuttings in hydroponic. Three experiments were carried out and in the experiments 1 and 2, the cuttings were rooted in fenolic foam and in nutritive solution, respectively. The treatments represented the cut positions of the cuttings in the axil of leaves 1 to 5, from the base to the apex. In the experiment 3, cuttings rooted in the experiments 1 and 2 were transplanted to vases containing nutritive solution and cultivated until the production of a single truss. The root fresh matter, root intersection, stem dry matter, leaf dry matter, root length, leaf area, leaf number and stem diameter, in the experiments 1 and 2, showed no significant differences between the treatments 1, 2, 3 and 4. In the experiment 3, fruit diameter presented significant difference between the treatments. Treatment 3 was superior to treatment 5, and the treatments 1, 2, 3 and 4 were similar. In hydroponic, it is possible to produce tomato seedlings through cuttings rooted in fenolic foam or nutritive solution.
