From the sea to the mountain: morphological variability of Rosa canina L. fruits from the Mediterranean part of Croatia

Dog rose (Rosa canina L.) is a wild fruit species widely distributed in Croatia in forest edges and agricultural areas. This research discusses the morphological variability of the dog rose fruits in the Mediterranean part of Croatia. Fruits were collected in situ, in four different ecological areas: the coastal region (Split and Klis) and the hinterland (Neorić and Kamešnica). Morphological characterisation of the fruits (fruit weight, fruit length, fruit width, fruit shape index) was performed. The results showed that the highest average weight (1.59 g) and fruit width (1.59 mm) was measured in the population Kamešnica, and the highest average height (20.13 mm) and fruit index (shape index ; 1.74) was determined in the population Klis. The greatest variability was determined for the trait fruit weight with a coefficient of variation of 41.58% (Klis) ; 41.03% (Split) ; 37.61% (Neorić) and 34.55% (Kamešnica). The obtained results indicate the need to expand the phenotype research on more populations in the Mediterranean part of Croatia, and to determine the influence of habitat, population size and climatic conditions on populations variability.
