Annotation

The large-seed group, or Cymosum group, includes 4 types of buckwheat: cultivated Fagopyrum esculentum Moench and Fagopyrum tataricum (L.) Gaertn., As well as wild-growing Fagopyrum cymosum Meissn. and Fagopyrum homotropicum Ohnishi. Despite the active use of these species in scientific research and human activities, many aspects of their morphology and reproductive biology remain unexplored at the moment. The aim of this study was to study the polymorphism of the flower structure and the development of the male reproductive sphere in large buckwheat species of the Cymosum group. As a result of studies, it was revealed that flowers with the formula P5A8G(3) typical for the genus Fagopyrum are found in the studied species with a frequency of 96-61%. Quite common options for the structure of the flower are also P5A7G(3), P6A8G(3), P6A3G(3), P5A9G(3), P5A8G(2) � P6A9G(3). By the number of variants of the structure of the flower, F. esculentumstood out, the least variable flower in F. homotropicum. The most variable part of the flower in all studied buckwheat species is androecium. A study of the embryological features of the species of the Cymosum group buckwheat showed that, in general, the processes of microsporogenesis and microgametogenesis are similar in species Fagopyrum . The studied species differed in the number of maternal microspore cells. F. esculentum significantly exceeded the other types of buckwheat in this indicator. The most frequent deviation in the development of the male reproductive sphere is the suspension of the development of sporogenous tissue cells and their subsequent degeneration. In all species of the studied buckwheat species, pollen fertility was found to be reduced, which is explained by disturbances during embryological processes during the formation of pollen. In F. esculentum and F. cymosum , pollen fertility decreased in response to drought. In F. homotropicum , pollen fertility was at a high level regardless of weather conditions.
