'Flordaprince' peach [Prunus persica (L.) Batsch] was submitted to two levels of green pruning intensity (mild and renewal), 45 days after harvest, with the objective of evaluating its effects on plant development, production, fruit quality and soluble carbohydrates in roots and branches. The experiment was carried out at University of São Paulo, Piracicaba, Brazil, in the 2003/2004 season. The experimental designed was entirely randomized, with two treatments and twelve replicates. Experimental unit comprised two plants at the 3,0 m x 1,2 m spacing and was conducted in central leader system. Biometric data collected were: effective flowering, sprouting, shoot length after green and winter pruning, quality and production of fruits, and soluble carbohydrates in roots and branches. Renewal pruning leads to lower soluble carbohydrate concentrations in the roots during dormancy. Renewal pruning also decreases fruit retention and Brix, even though it increases individual fruit weight. Green pruning intensities do not influence soluble carbohydrates concentration in branches, fruit growth or shoot growth after winter pruning. Soluble carbohydrate concentrations are always higher in the roots.
