Summary: Apomixis is a mode of asexual reproduction through seed, which can be classified into gametophytic and sporophytic apomixis. Although the occurrence of apomixis in higher plants is limited, it seems to be crucial for the genetic diversity of Garcinia species, many of which undergo apomixis. Understanding the reproductive processes of Garcinia species is necessary for the conservation and maintenance of genetic diversity.

Summary: Asexual reproduction leads to lower phenotypic diversity in seeds compared to sexual reproduction, but pseudogamous endosperm, variable endosperm ploidy, and maternal effects contribute to increased phenotypic diversity in apomictic offspring.

Summary: By analyzing the differences in embryological processes between plants from two populations in Southern Poland, the study established the costs of Biscutella laevigata adaptation to an environment polluted with heavy metals. The higher frequency of degenerations in plants from the calamine population could be interpreted as a strategy to save resources limited by the environment. The distribution of high-esterified homogalacturonan in the cell walls of embryos from the calamine population may be part of a resistance/defense system.

Summary: The mode of reproduction in Opuntia varies among species, including both vegetative and sexual reproduction, with animal seed dispersal playing a role. This study focused on fruit and seed production, seed dispersal, and animal consumption and removal of fruits in Opuntia phaeacantha. The results showed variation in fruit numbers and seed production among years and sites, with high losses and slower losses in years of high fruit production. Animal dispersers were found to consume fruit and spread seeds, with rabbits and deer being the main dispersers.

Summary: Morphological and phylogenetic analyses were conducted to clarify the taxonomic status of 10 Delphinium species in South-East European Russia. The study identified 4 distinct species and developed a dichotomous key for species identification in the study area. The recognition of species belonging to D. sect. Delphinastrum is hindered by intermediates forms and climatic conditions impact on morphological traits.

Summary: The vitality structure of 23 natural coenopopulations of Colchicum bulbocodium subsp. versicolor from the Lower Volga region was analyzed during 2014-2019, showing that northeastern coenopopulations have lower viability and higher instability compared to southwestern coenopopulations. Poor correlation was found among the studied morphological traits, with only two traits showing high correlation and six pairs showing medium correlation. In general, most coenopopulations were considered prosperous, with only a few showing depressive state in certain years due to extreme weather conditions.

Summary: This article studied the distribution and flower color variation of Polychromous Tulipa suaveolens in Europe. The results showed an evident color gradient from northeast to southwest, with the intensity of red color increasing. The distribution of yellow color was random. Additionally, the intensity of red color was found to be linearly dependent on temperature and precipitation parameters. The geographic trends in flower color distribution of T. suaveolens across its European range were concluded to result from natural selection driven by these abiotic factors.

Summary: This study sowed the fruits of Trapa natans in the Khoper and Volga rivers and found germinated rosettes in the Khoper River sowing sites. Based on morphometric parameters and seed productivity, the artificial plantings in the Khoper River were closer to the donor populations. Reintroducing Trapa natans is more challenging in the Volga River due to sharp water level changes in the seeding region.

Summary: Genetic analysis of 216 specimens from 22 natural Tulipa suaveolens localities in Europe revealed two genetic clusters, supporting the hypothesis that the evolution and distribution of the species were influenced by environmental changes.
