“…we suppose that colored vacuoles present in the epidermal cells of the ovule integument play a similar protective role during development of the female gametophyte. Besides Empetrum species, maximum accumulation of anthocyanins in epidermal cells of the mature ovules was observed in other plants, e.g., lonicera (Ďurišová et al, in press), and cerasus (Chudíková et al, 2012). we also assume that anthocyanins play the same protective role within colored vacuoles in the inner part of the gynoecium during the first stages of fruit development in Empetrum.…”

The aim of our research was to connect the detailed study of fruit anatomy of black crowberry (Empetrum nigrum) with identification and detection of the main non-anthocyanin polyphenolic compounds. Our experimental results showed that the highest accumulation of anthocyanin bodies occurred in mature fruits in outer layers during fruit development. The shape of the anthocyanin bodies was most often globular, spherical, hemispherical and intermediate types were present only occasionally. Mature cells of the gynoecium and pericarp generally contain anthocyanin bodies incorporated inside vacuoles. The observed compounds accumulated in cells were rutin, quercetin and catechins, resveratrol, coumaric, p-coumaric, caffeic, ferulic acids, gallic, vanilic, syringic, cinnamic and caffeic acids. These compounds were selected because of their proposed positive effects on health. The analyses of the polyphenolic spectrum showed predominance of ferrulic acid together with gallic acid and catechins with quercetin.

“…Meiotic irregularities during micro-sporogenesis that can result in different levels of infertility was previously studied by Dys (1984), Dirlewanger et al (2007), Chudíková et al (2012) and Iordache (2013). In cherries, varying degree of irregularities at meiosis observed in microsporogenesis has been correlated with pollen germination in vitro (Popovska et al, 2005).…”

The Oblačinska sour cherry (Prunus cerasus) is a mixture of different clones with similar tree and fruit characteristics that is indigenous to and widely planted in commercial orchards in Serbia. Sour cherry, including Oblačinska sour cherry clones, exhibits irregular meiosis which may contribute to low fruit set in some selections. The goal of this study was to examine the process of microsporogenesis and to determine if meiosis and its anomalies effect the in vitro pollen germination and pollen tube length in four 'Oblačinska' sour cherry clones that differ in fruit set and yields. All clones displayed varying degrees of chromosomal abnormalities in all meiosis sub-phases. The abnormalities became evident from late pachytene with more than half of the pollen mother cells (PMC) showing abnormal conjugation of chromosomes in metaphase I. The lowest number of PMCs with laggards was in clone III/9 and the highest in clone XIII/1. In second division, the univalent and multivalent association was observed at metaphase-II, the lagging and stickiness in anaphase-II, and the phenomenon persisted up to the microspore stage. In all four 'Oblačinska' clones, PMCs exhibited cytomixis phenomena, however, it was only observed in the second experimental year. Cytomixis differed among the four clones but was equally frequent in all stages of meiosis. The syncytia formed, most often consisted of 2-3 PMCs that were at the same phase of meiosis, and exhibited common cytoplasm and occasionally nuclear fusion. In vitro pollen germination and pollen tube length significantly differed between the clones. Most probably abnormalities during meiosis, regardless of the good results of pollen germination, influenced the reduced potential clones XI/3 and XIII/1.

“…Traditionally used morphological characters (abaxial hairs and plant height; Lepší et al., ; Wójcicki, ) have turned out to be more suitable in the field than the first three characters identified by morphometrics (i.e., distance from the widest part of the lamina to the laminar tip, laminar width and laminar length). However, the morphology‐based determinations of hybrid groups used in previous studies were probably not correct (Chudíková et al., ; Lepší et al., ; Wójcicki, ; Wójcicki & Marhold, ). Until now, almost all hybrids had been suggested to be tetraploid ( P .…”

“…Leaf shape (elliptic Fourier analysis) seems to be a useful complementary trait for distinguishing between pure Prunus species and hybrids, and a similar pattern was also detected in one local study of P. fruticosa (Czech Republic; Lepší et al., ). Thus, based on DNA ploidy level knowledge, the results of previous studies (Chudíková et al., ; Lepší et al., ; Wójcicki, ; Wójcicki & Marhold, ) might have to be substantially reevaluated.…”

Crop cultivation can lead to genetic swamping of indigenous species and thus pose a serious threat for biodiversity. The rare Eurasian tetraploid shrub Prunus fruticosa (ground cherry) is suspected of hybridizing with cultivated allochthonous tetraploid P. cerasus and autochthonous diploid P. avium. Three Prunus taxa (447 individuals of P. fruticosa, 43 of P. cerasus and 73 of P. avium) and their hybrids (198 individuals) were evaluated using analysis of absolute genome size/ploidy level and multivariate morphometrics. Flow cytometry revealed considerable differentiation in absolute genome size at the tetraploid level (average 2C of P. fruticosa = 1.30 pg, average 2C of P. cerasus = 1.42 pg, i.e., a 9.2% difference). The combination of methods used allowed us to ascertain the frequency of hybrids occurring under natural conditions in Central Europe. The morphological evaluation of leaves was based upon distance‐based morphometrics supplemented by elliptic Fourier analysis. The results provided substantial evidence for ongoing hybridization (hybrids occurred in 39.5% of P. fruticosa populations). We detected homoploid introgressive hybridization with alien P. cerasus at the tetraploid level. We also found previously overlooked but frequent triploid hybrids resulting from heteroploid hybridization with indigenous P. avium, which, however, probably represent only the F1 generation. Although both hybrids differ in ploidy, they cannot be distinguished using morphometrics. Hybrids are frequent and may endanger wild populations of genuine P. fruticosa via direct niche competition or, alternatively or in addition, via introgression at the homoploid level (i.e., genetic swamping). The cultivation of cherries thus substantially threatens the existence of genuine P. fruticosa.
