Fruit quality in five apple cultivars trees trained to intensive training system: Geneva y-trellis

摘要: Orchard intensification is motivated by the desire to produce fruit early in life of orchard rapidly recover establishment costs. Intensification possible using dwarfing rootstocks that control tree size, induce cropping, and large quantities relative amount wood produced. Therefore, this study attempts compare some yield properties five apple cultivars grown in Karaj area Iran. The concerned were ‘Golab-kohans’ (Iranian cultivar), ‘Fuji’, ‘Starking’, ‘Delbar estival’ ‘Prime rose’ (commercial foreign cultivars) grafted on M.9 rootstock which trained Geneva Y-trellis system. All these trees planted winter 2004. The irrigated from second year after planting method of irrigation was drip irrigation. pH (4.07) Humidity Content (85.96 %) were highest with (Iranian cultivar). Also estival’ had length (6.13 cm), L/D (0.87) TSS (15.77). ‘Starking’ weight (145.24 gr), diameter (6.91 cm) Ash (0.71 %). In addition, most dry matter (20.13 %), firmness (13.13 kg/cm2) titrable acid (0.72 recorded ‘Fuji’.
