Fruit Properties of Rose Hip Species Grown in Lake Van Basin (Eastern Anatolia Region)

Abstract

In this study, some chemical and technological fruit attributes of rose hip species grown in the Lake Van Basin (Eastern Anatolia Region) were studied. Attributes such as fruit and stone length, width (mm) and weight (g), fruit flesh ratio (%), the water-soluble extracts (%), pH, titretable acidity (%) and dry matter content (%) were evaluated. Evaluated fruit attributes of the rose hip genotypes were significantly different from each others (p<0.05). Fruit weights were between 1.50 and 3.74 g. Rosa dumalis (Rd) has the heaviest average fruit weight of 3.11 g. However, this genotype has the lightest flesh ratio (57.2%) because of the highest stone weight. Fruit shape index were between 1.06 and 2.12. The rose hip samples had a range of 11-25% for water-soluble extract, 3.95-4.57 for pH, 0.35-1.14 for titretable acidity and 34.34-66.70 for dry matter content. Rosa foitida and Rosa pisiformis has the highest water-soluble extract of 20.54 and 20.33, respectively. Variations in water-soluble extract are of great importance. Chemical and technological values of the investigated rose hip species showed a similarity to that studied from other native rose hip populations earlier. © 2006 Asian Network for Scientific Information.
