S. Tepe, M.A. Koyuncu
In this study, fruit quality of 16-year-old tree ‘Gold Nugget’ loquat cultivar, which is grafted on Quince A, hawthorn and loquat rootstock seedlings were investigated in Antalya. Fruit weight, firmness, skin color, fruit/seed rate, soluble solid content, titratable acidity, maturity index, ethylene production, respiration rate and sensory analysis were evaluated to determine the effect of rootstocks on fruit quality. Trials were conducted according to completely randomized design (CRD) with three replications. According to the results; Quince A had the ability to increase fruit weight for ‘Gold Nugget’ loquat cultivar, the seed ratio in this cultivar was higher in hawthorn-grown fruit than those of other rootstocks. Total soluble solid content in the fruit of ‘Gold Nugget’ - loquat combination was lower than other rootstocks. Fruit grown on hawthorn rootstock had more yellowish green color than the others, while fruit grown on loquat rootstock had vivid and orange-yellow shades. Fruit grown on Quince A and loquat rootstocks were found to have better appearance and flavor than those of hawthorn rootstock. As a result, ‘Gold Nugget’ cultivar grown on Quince A and loquat rootstocks might be more appropriate for loquat cultivation, the fruit of these combinations can easily be used as a fresh consumption and processed product such as jam and jelly.
