| Popis: | Seasonal mineral composition of ‘Starkspur Golden Delicious’ apple fruit (Malus domestica Borkh.) grown on six rootstocks: Mailing (M) 1, M 7, M 26, Mailing Merton (MM) 106, OAR 1 and seedling rootstocks in a high density orchard with two levels of K (K2SO4) and two levels of N (urea) soil fertilization were studied in 1980 and 1981. The concentrations (dry weight basis) of all minerals declined in fruits of all treatments as the season progressed. However, fruit from OAR 1 stock generally had about 15% lower N, P, K, Mg, Fe, and Cu, but about 17% higher B, whereas fruit from M 7 had about 10% higher concentrations of N, K, Fe and Cu than most other rootstocks. Fruit on M 26 had about 6% lower concentrations of B than most other stocks in both seasons. Scion fruit on OAR 1 had the lowest mineral content (total mineral per fruit) except for B which was about 11% higher for this rootstock than most other rootstocks. Crop load was found to affect mineral contents particularly fruit of light cropping... |
