Resumo
The tomato crop is of great versatility and importance in the socioeconomic development of the
Country. This research was aimed at evaluating the effects of different paclobutrazol concentrations
in the production of seedlings of two tomato hybrids. This research was conducted at Teaching,
Research and Extension Farm of the College of Engineering of Ilha Solteira, UNESP. State of São
Paulo, Brazil. The experimental design was completely randomized, in factorial outline 4 x 2, being
four paclobutrazol concentrations (0. 50. 100 and 150 mg L -1 ) and two tomato hybrids (Jennifer
and AF 7631), with four replications. We evaluated the effects of PBZ on the quality of seedlings in
the seedling height, diameter of stem, ratio diameter / height of seedlings, leaf area, dry mass of
shoots and roots, ratio of dry root and dry weight of air and absolute growth rate. The application of
different concentrations of paclobutrazol influences the development of seedling shoots. The use of
paclobutrazol reduces dry mass, increased root biomass and increases the quality of the changes
produced.
