| description | The aim of the study was to evaluate the effect of applying a paclobutrazol growth regulator on plants and plant spacing in the planting lines of industrial tomatoes was evaluated. The experiment was conducted from July to October. A randomized block strategy in a 5×2 factorial design (spacing x presence or absence of paclobutrazol) was used. The length of the main stem and stem diameter of the plants, chlorophyll content in leaves, total production (t ha-1), average number of fruits and fresh fruit weight, distribution of ripe, unripe and rotten fruits, number of ripe and unripe fruits, average weight of ripe and unripe fruits, soluble solids content, titratable acidity, pH, SS/TA ratio, percentage of compression and maximum strength to break and paclobutrazol residue in fruits were all determined. The results showed that Paclobutrazol influences the length of rods and chlorophyll content in leaves up to 15 days after transplanting, showing that the effect of the regulator is limited during the culture cycle. And, the regulator did not influence the production parameters of the industrial tomatoes. The application of PBZ did not influence any of the chemical or physical quality parameters that were evaluated. The plant densities studied did not alter the production and fruit quality components of the tomato. No residues of paclobutrazol were detected in tomato fruits for industrial processing that received an application of the regulator in the seedlings. |

No residues of paclobutrazol were detected in tomato fruits for industrial processing that received an application of the regulator in the seedlings. O estudo teve como objetivo avaliar o efeito da aplicação do regulador de crescimento paclobutrazol nas mudas e do espaçamento entre plantas na linha de plantio do tomate industrial. O experimento foi conduzido de julho a outubro de 2013 em Anápolis, GO. Utilizou-se o delineamento em blocos casualizados, em esquema fatorial de 5×2 (espaçamento × presença ou ausência de paclobutrazol). Foram determinados o comprimento da haste principal e diâmetro médio do caule das plantas, teor de clorofila nas folhas, produção total (t ha-1), número médio de frutos e massa fresca de frutos, distribuição dos frutos em maduro, verde e deteriorados, número de frutos maduro e verde, massa média de frutos maduro e verde, teores de sólidos solúveis, acidez titulável, pH, relação SS/AT, porcentagem de compressão e força máxima para rompimento da epiderme e resíduo de paclobutrazol nos frutos. Os resultados mostraram que a aplicação de paclobutrazol influencia até os 15 após o transplantio o comprimento das hastes e o teor de clorofila nas folhas, mostrando que o efeito do regulador é limitado durante o ciclo da cultura, não influenciando sobre os parâmetros de produção do tomate industrial. A aplicação de PBZ não influenciou em nenhum dos parâmetros de qualidade química e física avaliados. As densidades de plantio estudadas não alteraram os componentes de produção e qualidade de frutos do tomateiro. Não foram detectados resíduos de paclobutrazol em frutos de tomateiro para processamento industrial que receberam a aplicação do regulador nas mudas.
