Effects of Apple Rootstock, Tree Spacing, and Cultivar on Fruit and Tree Size, Yield, and Foliar Mineral Composition1

Abstract: The influence of 3 spacings, 4 rootstocks, and 2 cultivars of apple (Malus domestica Borkh.) on yield, fruit and tree size and mineral composition of leaves during the 3rd through the 6th year of growth in the orchard were investigated. Scion cultivar had the greatest effect on mineral composition; all elements except manganese were significantly different in the 2 spur-type cultivars (‘Goldenspur’ and ‘Redspur’). Trees on Mailing Merton (MM) 106 rootstock produced larger yields than those on other rootstocks,… Show more

“…Studies of rootstock influence on the quality of scion cultivars are limited only to storage bitterpit (11). Although some attention has been directed toward spacing and yield (8) and quality of 'Golden Delicious' apples in high density orchards (13), the influence of various rootstocks on the keeping and eating quality of spur type 'Golden Delicious' from high density systems has not been reported. The objective of this research was to study the influence of 6 rootstocks (Seedling, M 1, MM 106, M 7, OAR 1, and M 26), 2 levels of K and N fertilizers, and 3 harvest dates on quality at harvest and after storage of 'Starkspur Golden Delicious' apple fruit from a high density orchard.…”

“…Leaves from 'Delicious'/MM 106 contained more Ca than did those from ' DeliciousVM 7/MM 104 (Table 2). Trees on MM 106 were among the highest in leaf Ca (2, 10, 13); M 7 induced low Ca levels (14). Using a rootstock that accumulates more Ca is a possible solution to apple disorders related to low fruit Ca (11).…”

“…Apple trees on M 9 rootstocks, for example, had higher foliar Ca and Mg levels than did those on M 7; trees on M 2 had higher foliar P, Ca, and Mg levels than did those on M 7; trees on M 2 had higher foliar P, Ca, and Mg levels than did those on M 16; M 7 rootstocks considerably reduced foliar Mg (18). MM 106 rootstock caused higher foliar Ca than did MM 111 (10,14); and trees on M 26 had significantly higher leaf Mn than did those on M 9/MM 106, M 2, or MM 109 (12). Transport rate of 45Ca and 32P to roots and scion is known to be related to the vigor class of the tree (4).…”
