Abstract
The genus
Crataegus
L. is one of the largest species in the family Rosaceae Juss. The fruits are used as medicinal raw materials (
Crataegus fructus
), as they contain a set of biologically active compounds. The genus is voluminous and taxonomically problematic due to significant variability, hybridization, apomixis, and polyploidy. As a result, it is difficult to determine the species of the genus. Species of the genus have a number of diagnostic features, one of which is a distinct fruit with seeds. The aim of our study was to identify and compare the diagnostic features of the fruits of seven species of the genus
Crataegus
flora of Ukraine, which are most often used as medicinal raw materials and are the most common in Ukraine –
Crataegus laevigata
,
C. monogyna
,
C. pentagyna
,
C. pseudokyrtostyla
,
C. sanguinea
,
C. fallacina
, and
C. rhipidophylla
. The study was performed using scanning and digital microscopy, and descriptions were made by standard methods. As a result, we identified features that clearly distinguished the studied species from each other. We identified mature fruits that contain only one pyrene (
C. monogyna
,
C. pseudokyrtostyla
,
C. fallacina
, and
C. rhipidophylla
), and several pyrenes (
C. laevigata
,
C. pentagyna
, and
C. sanguinea
) among the studied species of the genus. The studied species are characterized by spherical and ellipsoidal fruits. The predominant color is fulvous/brown with different shades, but almost-black fruits of the species
C. pentagyna
are well distinguished. Fruits of all studied species of the genus are fleshy, except
C. sanguinea
, which is floury. The species is characterized mainly by yellow flesh fruits, except
C. pentagyna
, which has ribbed fruits. The fruits of
C. monogyna
plants differ from those of other studied species by the spinous-tuberous surface relief. Pyrenes of triangular shape are observed only in
C. pentagyna
. We suggest that these features can be used as additional diagnostic tools to determine the species of the genus
Crataegus
flora in Ukraine.

期刊介绍:
The Acta Agrobotanica publishes mainly significant, original research papers presenting the results new to the biology of cultivable or wild plants accompanying crops. The submissions dedicated particularly to flora and phytocenoses of anthropogenically transformed areas, bee pastures, nectariferous and polleniferous taxa, plant-pollinator relationships, urban and rural habitats for entomofauna, cultivated plants, weeds, aerobiology, plant pathogens and parasites are encouraged and accepted. Besides the original research papers, authors may submit short communications and reviews. The journal also publishes the invited papers in case of new developments in plant science. All submissions must be written in good English, which is solely a responsibility of the authors.
