FRUIT QUALITY PARAMETERS OF APPLE CULTIVAR ‘GRANNY SMITH’ PRODUCED ON NINE DIFFERENT DWARFING ROOTSTOCKS

The influence of ‘M.9 T 984’, ‘M.9 T 337’, ‘Jork 9’, ‘Mark 9’, ‘Budagowski 9’, ‘M.9 EMLA’, ‘Pajam 1’, ‘Pajam 2’, ‘Supporter 4’ apple rootstocks on fruit quality of ‘Granny Smith’ apple variety (Malus domestica Borkh.) was analyzed.
The study was performed during three consecutive years in the Prespa region (Resen, R. Macedonia). Fruit size, fruit weight, firmness, soluble solid concentration and acidity were measured for fruit quality evaluation.
In general, the effect of the different rootstocks on most of the analyzed quality parameters was variable because a strong interaction rootstock x year was observed.
However, several parameters as fruit weight, soluble solid concentration, acidity and firmness of the fruits in some rootstocks, did not show significant differences year-by-year.
Fruits produced on scions grafted on ‘M.9 T 984’ showed the highest value for fruit weight soluble solid concentration and acidity.
Fruits produced on rootstock ‘Budagowski 9’ have the lowest value for fruit weight and total acids but highest value for fruit firmness.
