Resumo: | The paclobutrazol (PBZ) application can slow growth and increase flowering in certain fruit species by reducing root growth and gibberellins synthesis. In addition, other plant characteristics can be influenced by the PBZ application as carbohydrates concentrations. This work was carried out aiming to evaluate the relationship between the carbohydrates concentration in leaf and reproductive development in olive tree through the PBZ application. Three-year-old olive plants of cultivar Arbequina were grown in 20 liters pots outdoors. We used five doses PBZ: 2.0, 4.0, 8.0 and 12.0 mL plant-1 distributed in a completely randomized design with four replications and two plants per plot were applied to soil. The evaluation of reproductive development and carbohydrates concentration was carried during the flowering season of plants. The PBZ application promoted to increase in flower racemes number. The greater carbohydrate accumulation in leaves was observed in plants submitted to PBZ application.
