Akçadağ (Malatya) Yöresinde Yetişen Alıç Genetik Kaynaklarının Şeker İçerikleri

Abstract

Objective: In this study was aimed to determine the sugar contents of hawthorn genetic resources grown in the Akçadağ (Malatya) region. Materials and Methods: The study material was consisted in 15 genotypes belonging 5 different hawthorn species. In investigated hawthorn genotypes, glucose, fructose, sucrose and total sugar content were determined. Results: A wide variation was determined between the species and genotypes studied in terms of investigated characteristics. Based on species, Crataegus pontica stood out in terms of glucose, fructose, and total sugar content (11.0 g 100 g-1, 12.7 g 100 g-1, and 26.1 g 100 g-1, respectively), and Crataegus aronia in terms of sucrose content (3.7 g 100 g-1). Depending on the genotypes, the highest glucose, fructose, and total sugar content (21.0, 23.6, and 45.0 g 100 g-1, respectively) were determined in the H-1 genotype, and the highest sucrose content (3.7 g 100 g-1) was determined in the H-15 genotype. According to the principal component analysis results, the first two components explained 99.8% of the total variation. While the first component was related to glucose, fructose, and total sugar contents, the second component was related to sucrose. Conclusion: It is thought that the examined hawthorn genetic resources have significant potential in terms of sugar content and can be used as genetic material in breeding studies.
