Peach production in the U.S. relies on standard size trees on vigorous, seedling rootstocks grown at low-densities (≤ 297 trees/ha). Production per hectare is low. Peach tree growth habits, such as pillar (P) (columnar canopy shape) and upright (U), can be planted in high-density systems with the potential for increased production per hectare. Pillar and upright, advanced breeding selections, a...

Abstract: The objective of this work was to evaluate the effect 19 clonal rootstocks on vegetative growth and foliar nutrient contents 'BRS Kampai' Rubimel' peach (Prunus persica) trees. In period 2014 2018, two field trials were carried out in municipalities Jarinu Jundiaí, state São Paulo, Brazil. BRS Kampai Rubimel cultivars, budded rootstocks, besides their own-rooted scions, evaluated resp...

starting from semihardwood branches of peach and plum rootstocks (Prunus cerasifera E.) cv. mrs2/5, plum rootstocks (Prunus cerasifera × P. salicina) × (P. cerasifera × P. persica) cv. ishtarà and olive tree (Olea europaea L.) cv. Frantoio, cuttings were collected and treated with 0 mg.L and 2500 mg.L of indolebutyric acid (iBa) by immersion in the base of the cuttings. after 60 days of plantin...

Forms of aluminum (Al) present in the solution tropical and subtropical soils can cause toxicity rootstocks peach cultivars, impairing growth productivity. This be minimized by growing Al-tolerant cultivars. However, this is not sufficiently known, especially because plant breeding programs do always consider tolerance as a selection variable for genetic materials. The study aimed to (a) select...
