Abstract: The aim of this study to evaluate the effect of altitude (800 m, 900 m, 1000 m and 1150 m) on
some important morphological and biochemical characteristics of autochthonous grape cultivar,
‘Kabarcik’ grown in Olur district in Turkey. Cluster weight, cluster length, cluster density, cluster
stalk length, berry shape and berry skin color were investigated as morphological traits. Biochemical
parameters included total phenolic content, total flavonoid content, phenolic acids, antioxidant
activity, soluble solid content (SSC) and titratable acidity. Cluster weight and density are decreased
with altitude increase but cluster stalk length is increased with altitude increase. Cluster weight were
found between 192-281 g at different altitudes. Cluster length were determined as 19.82 cm, 17.56 cm,
15.16 cm and 14.88 cm at 800 m, 900 m, 100 m and 1150 m altitude, respectively. SSC and titratable
acidity were increased with altitude increase. Total phenolic content, total flavonoid content, phenolic
acids and antioxidant activity were found to be higher level at higher altitudes. The results indicate
the importance of altitude of grape external and internal berry quality.
