Abstract The current research was conducted to study on some morphological and physiological properties of red Hawthorn fruit based on a completely randomized design with three replications in four regions of the Zanjan province (Zanjan, Mahneshan, Abhar and Tarom). The wet and dry weight, fruit length and diameter, fruit firmness and fruit seed number were determined. Statistical analysis revealed that different ecotypes had significant effect (p<0.05) on dependent variables expect fruit firmness. Results also showed that the highest wet weight (1.83±0.05 gram), dry weight (0.65±0.04g) and diameter of fruit (14.89±0.21mm) were related to the Abhar region and the maximum length of the fruit (14.78±0.75 mm), flesh firmness (1.083±0.17 kilogram per square centimeter) and seed number (3.063±0.17) corresponds to the Tarom region and the minimum level of wet weight (1.09±0.05 gram), dry weight (0.36±0.05 g), fruit length (11.84±0.56 mm), fruit diameter (10.69±0.54 mm), number of seeds (1.16±0.28) corresponds to the Mahneshan region. The lowest fruit firmness (0.59±0.18 kilograms per square centimeter) was observed in Abhar region. Keywords: Ecotypes, Hawthorns, morphological propertiees
