Effects of M9 and MM106 rootstocks on agromorphological characteristics of ‘Golab kohanz’ and ‘Delbarstival’ apple cultivars in Abhar region of Iran


Dwarf rootstocks find use to increase yield in a unit area. Therefore, the aim of the study is to compare and examine M9 dwarf and MM106 semi-dwarf rootstocks on some vegetative and yield traits of ‘Golab-kohanz’ (Iranian) and ‘Delbarstival’ (commercial foreign) cultivars of apple, grown at orchard in Abhar, Iran. Results showed that the ‘Golabkohanz’ on the MM106 rootstock had the most mean shoot length of the current year (39.97 cm) and tree height (198.33 cm). Also ‘Golab-kohanz’ (6.40 cm), (33.58 cm2 ) and MM106 rootstock (7.39 cm), (33.09 cm2 ) had the most trunk diameter and trunk cross sectional area respectively. The most internode length of the current year belonged to MM106 rootstock (5.12 cm). ‘Delbarstival’ (141 cm) and M9 Rootstock (133 cm) had the most canopy width tree. Then, ‘Delbarstival’ on M9 rootstock had the most yields of trees (14.61 kg tree-1 ), yield in hectare (40.56 ton ha-1 ) and yield efficiency (519.33 kg cm2 ). Pursuant to results, among experimented rootstocks and cultivars, ‘Delbarstival’ on M9 rootstock is the proper compound for achieving the largest yield cropping in intensive planting orchards system in Abhar climatic conditions.
