Treatments to Increase the Final Fruit Size on Satsuma "Clausellina"

Abstract

In order to determine the best treatments to increase the final size of the fruits of the satsuma “Clausellina” [Citrus unshiu (Mak.) Marc.], the following experiments have been conducted: 1. Hand-thinning: Two degrees of thinning: 33 % and 66 % of flowers-frults present, in four periods, between flowering and ripening. 2. Pruning: Removing 30 % and 50 % of the canopy in three periods between flowering and summer. 3. Chemical products: Applications of several growth regulators after June drop. The effects of these treatments on fruit size and yield will be presented and discussed.
