Multivariate Analysis Revealed the Morphological Variability Among Crataegus Species

Abstract

The Crataegus genus has many species growing as wild that have positive effects on human health. The information about the phenotypic diversity of this species is rather inadequate. Phenotypic diversity among forty-four genotypes belonging to four Crataegus species (C. monogyna, C. orientalis, C. astrosanguinea, and C. meyeri) was determined based on morphological and physicochemical characteristics. Significant differences were observed among the species in terms of studied characteristics. Fruit weight ranges from 1.60 to 2.50 g for C. orientalis, 1.53 to 2.33 g for C. meyeri, 1.26 to 2.41 g for C. astrosanguinea, and 0.38 to 1.98 g for C. monogyna. The highest fruit length (15.19 mm) and width (17.58 mm) were determined in C. orientalis. The heights color values, L*, a*, and hue o values were highest in C. meyeri, while b* value was highest in C. monogyna and Chroma* was in C. orientalis. The highest TSS and pH were found in C. monogyna as 3.99% and 4.33%, respectively. TA was highest in C. monogyna with 1.83 mg L -1 . Seed size ranged from 1.36 (C. monogyna) to 4.33 (C. orientalis), while seed weight ranged from 0.23 g to 0.45 g in C. mongyna and C. astrosanguinea, respectively. The correlation analysis indicated significant correlations between morphological characters. The principal component and clustering analyses revealed high phenotypic variety among and within the species, showing that the studied characters were useful for describing Crataegus species. The results provided valuable insights for morphological and colorimetric characterization of hawthorn species and their utilization.

“…The PCA and heatmap analysis have started to be utilized in research studies to evaluate the differentiation of the factors according to the studied characteristics from the visual point of view [57,58]. By examining the biplot, it is possible to observe the relative positions of the varieties and drying methods, indicating their similarities or differences in terms of the studied traits.…”

“…PCA was used to determine critical characters and to minimize the number of effective factors. Therefore, PCA has been used intensely by researchers to define critical characteristics of fruit species for the last decade (Mratinic, et al, 2011;Güler et al, 2021;Muradoğlu et al, 2021). In this study, PCA was conducted to characterize morphological characters of Turkish and foreign varieties.…”

“…Among these species, Crataegus monogyna, C. orientalis, C. curvisephala, C. pentagyna, C. oxycantha, C. azaralus and C. prunitifolia have a wide distribution area in Türkiye (Ercisli, 2004;Muradoğlu et al, 2021). Although some hawthorn species are cultivated in different regions in the world, hawthorns generally show natural distribution (Payne and Krewer, 1990).…”
