Abstract
Article Details: Received: 2019-12-17 | Accepted: 2019-01-24 | Available online: 2020-03-31 https://doi.org/10.15414/afz.2020.23.01.15-23 In this paper, morphological features, such as the number of pyrenes in pome and the number of pomes in infructescence, were used for determination of closely related tetraploid Cotoneaster species. Samples were collected from various localities in the Western Carpathians. The collection of samples, designed for counting of pyrenes in pome, included 2353 pomes of >130 individuals. Number of pyrenes in pome ranged from 1 to 5. Statistical analysis revealed a significant difference in pyrenes per pome mean values between C. integerrimus (3.01), C. melanocarpus agg. (2.46; including C. matrensis) and C. tomentosus (3.93). The collection of samples, designed for counting of pomes in infructescence, included 1019 infructescences of 141 individuals. Number of pomes in infructescence ranged from 1 to 5. Statistical analysis also revealed a significant difference in pomes per infructescence mean values between C. integerrimus (1.14) and C. melanocarpus agg. (1.54; including C. matrensis), and between C. integerrimus and C. tomentosus (1.50). Keywords: pyrenes, pomes, infructescence, Cotoneaster, Western Carpathians
Highlights
According to the latest research, the Cotoneaster genus belongs to Rosaceae family, Spiraeoideae subfamily and tribe Pyreae (Potter et al, 2007)
Pomes and infructescences were collected from various localities in four countries situated in the Western Carpathians – the Czech Republic, Hungary, Poland and Slovakia (Figure 1, 2)
The list of localities selected for counting of pyrenes in pome and for counting of pomes in infructescence is listed in Appendix 1 and 2, respectively
Summary
According to the latest research, the Cotoneaster genus belongs to Rosaceae family, Spiraeoideae subfamily and tribe Pyreae (Potter et al, 2007). Overall, it includes approximately 300 species (Bartish et al, 2001). Many species, included in Cotoneaster genus, are cultivated as ornamental plants (Dickoré and Kasperek, 2010). Latest research confirmed a presence of phenolic compounds and flavonoids in Cotoneaster integerrimus. C. integerrimus has a great potential in health promotion. Novel food ingredients and medication could be developed from its twigs and fruit (Uysal et al, 2016; Kicel et al, 2019)
