Abstract

Hawthorn is systemically subordinate to the Crataegus genus of the Rosaceae family. It has been reported that there exists approximately 100 up to 1100 species of hawthorn in temperate regions of North America and 50 up to 100 species in temperate regions of the old world. Due to polymorphism, hybridization, apomixis, and cultivation preferences, Crataegus species vary widely. Turkey, as well as being an important diversity center for hawthorn species grown in natural conditions, is reported to be home for 31 hawthorn species. In this study, some physical, morphological, pomological and habitational characteristics of hawthorn genotypes naturally grown in Malatya, Hatay, Gumushane, Gaziantep, Bingöl, Mersin and Aksaray provinces have been determined. Fruit samples from 20 hawthorn genotypes naturally grown in these zones were collected, and in these genotypes, it was determined vitamin C, sugar composition, habitational characters, habitus, vestiture, fruit weight (g), dimensional features of fruit (length and width) (mm), pulp seed ratio in fruit, seed count, pH and brix. In addition, blooming and fruit ripening dates were recorded. In the examined genotypes, the color of the fruit determined to vary between light green, yellow, orange, red and purple, and the number of seeds was between 1 and 5. It has been determined that genotypes grow in mountainous, rocky areas as well as in flat areas, and are represented by tree and shrub form.
