Peach trees require pruning (specifically, fruiting shoots pruning, FSP) and fruit thinning (FT) for commercial fruit production. In the 2004-05 growing season, the interaction between FSP and FT on yield, fruit size distribution, fruit quality, fruit and shoot growth, and specific leaf weight of the ‘Victoria’ peach cultivar were studied. The experiment was conducted at the Zacatecas Experimental Station (at the Mexico’s Zacatecas State) using twenty-year old peach trees grafted on standard rootstock. The factors studied were: FSP and FT, both factors with two levels each: with and without FSP, and with and without FT. The statistical analysis did not detect any significant (P£0.05) interaction among the levels of the factors and response variables. Except for the significant (P£0.05) induction of first class fruits (5.0-4.4 cm of equatorial diameter), FT did not influence statistically (P£0.05) any of the remaining response variables. The FSP significantly (P£0.05) promoted fruit with equatorial diameters > 5.1 cm in relation to control trees (without FSP), but yield and productive efficiency were reduced (P£0.05) when FSP was applied. Average fruit weight, mesocarp, and endocarp were significantly (P£0.01) higher in fruit with FSP. However, firmness, total soluble solids concentration, fruit dry matter concentration, and specific leaf weight were statistically (P£0.05) the same between fruit without and with FSP. Results suggest that FT can be obviated in ‘Victoria peach trees, and therefore, this would reduce production costs. Both factors deserve to be studied in other peach cultivars whose reproductive structures have more ability to utilize photo assimilates.
