Abstract :In this research, the effect of rootstocks on the ripening chracterictics such as total soluble solidity (TSS), total acidity (TA) and TSS/TA were studied on the grape cultivar Narince during ripening period. In addition, the results of organoleptic tests (OT) that grupped by TSS and TA were valued. The highest value of TSS was found from the grape sample on the rootstock Lot aproximetely all harvest time. The least TSS analised from the 41 B rootstock. TSS, TA and ripenning indexes (RI) were significantly different among rootstocks. The highest TA was analised from the 140 Ru (10.24 g/l at first harvest) and 1103 P (7.22 at the fourth harvest). On the other hand TA was decreased below to 4.52 g/l on the rootstock 420 A at the fourth harvest. The value of RI were recorded between 16.59 (at the first harvest on the rootstock 41 B) and 43.07 (at the fourth harvest on the rootstock Lot). The correlation between rootstocks and RI due to harvest time were calculated as -0.345, -0.389, -0.307 and -0.482 respectively. The OT values were varied between 3.7 (at first group) and 7.9 (at 16th group) according to performed ripennig group.
