Despite the extensive use of dwarfing rootstocks in commercial apple cultivation worldwide, it is presently unknown how different growing environments may modify the first expression of rootstock-induced dwarfing of the scion. To address this, we measured the growth and architectural development of compound ‘Royal Gala’ apple trees grafted onto three different vigour clonal rootstocks (‘M27’, ‘M9’ and ‘M793’), grown in three locations of New Zealand. Detailed architectural measurements were made over the first year of growth after grafting and the study was repeated for a second year. Within each site and year, trees on ‘M793’ had the greatest primary axis length and node number, trunk cross-sectional area, number of sylleptic shoots and final tree dry weight, while those on ‘M27’ had the smallest. Trees on dwarfi.. View More»
