The pruning time and pruning severity of fruiting shoots as well as the elimination of weak unmixed fruiting were studied in a commercial orchard of five‑year‑old clingstone peach trees cultivated under rained conditions in the Mexican tropic. Fruit weight with equatorial diameter >5.1 cm was significantly (P ≤ 0.05) increased by winter pruning and eliminating a 25% of fruiting shoot length. Fresh and dry fruit growth and vegetative growth as well as some fruit quality variables were significantly (P ≤ 0.05) improved by the same treatment. The opposite effect was observed when trees were spring pruned.
