“…However, in that case the analysis was carried out to verify divergence among varieties differing in seed quality, and genotypes of each type were not equally represented on every harvesting date (Pierre et al, 1999 ). Therefore, this is the first report clearly showing the occurrence of a high variability in rapeseed regarding this trait, as shown to occur in other Brassicaceous species (Denisow et al, 2015 ).…”

Numerous angiosperms rely on pollinators to ensure efficient flower fertilization, offering a reward consisting of nourishing nectars produced by specialized floral cells, known as nectaries. Nectar components are believed to derive from phloem sap that is enzymatically processed and transformed within nectaries. An increasing body of evidence suggests that nectar composition, mainly amino acids, may influence pollinator attraction and fidelity. This notwithstanding, little is known about the range of natural variability in nectar content for crop species. Sugar and amino acid composition of nectar harvested from field-grown plants at the 63–65 phenological stage was determined for a set of 44 winter genotypes of rapeseed, a bee-pollinated crop. Significant differences were found for solute concentrations, and an even higher variability was evident for nectar volumes, resulting in striking differences when results were expressed on a single flower basis. The comparison of nectar and phloem sap from a subset of eight varieties pointed out qualitative and quantitative diversities with respect to both sugars and amino acids. Notably, amino acid concentration in phloem sap was up to 100 times higher than in nectar. Phloem sap showed a much more uniform composition, suggesting that nectar variability depends mainly on nectary metabolism. A better understanding of the basis of nectar production would allow an improvement of seed set efficiency, as well as hive management and honey production.

“…Aggressive in Europe, a perennial plant, B. orientalis L. forms dense monotypic stands in man-made habitats and invades meadows, thermophilous swards and pastures [67,68]. This species is a plant with a showy floral display and attractive nectar and pollen reward [69], and has the potential to alter plant-pollinator interactions. Negative effects of invasive species on the pollination and reproductive success of native plant species have been reported [70].…”

Invasive flora within urban railway areas: a case study from Lublin (Poland) and Lviv (Ukraine)

Heterogeneous and disturbed habitats within railway areas create an ideal environment for establishment of invasive plant species. In this study, we compared the invasive species composition and abundance within railway areas of two cities, Lublin, SE Poland and Lviv, W Ukraine. In total, 70 invasive species were recorded. The invasive species list was similar for the two cities, with the most invasive species occurring at both (81.4%), 8.5% occurring only in Lublin and 10% only in Lviv. The proportion of invasive species in the total flora was almost 1.5-fold higher at Lviv compared to Lublin. Invasive species have originated mainly from continental America (45.7%), followed by Asia and Eurasia. The participation of invasive plants derived from Asia and Eurasia at Lviv is higher than at Lublin. The invasive flora includes a wide range of taxonomic groups, with a predominance of Asteraceae and Poaceae. The ecological attributes of invasive species on railway areas are: mainly annual therophytes, mostly wind-and insect pollination modes, a predominance of generative reproduction, anthropochorous and anemochorous dispersal and short-term persistent, long-term persistent or transient seed banks.

“…explained this plant as invasive (Dietz and Winterhalter, 1996;Dietz et al, 1999;Patamsitė et al, 2013). Also, it was studied nectar production and carbohydrate composition of this species (Denisow et al, 2016). Nevertheless, the accumulation of some biochemical compounds in different organs causes the useful properties of B. orientalis (Vinogradova and Kuklina, 2018).…”

The current study was aimed to evaluate an accumulation in plant raw material of Bunias orientalis L. and Scorzonera hispanica L. the total content of phenolic compounds, phenolic acids, flavonoids, antioxidant activity (by DPPH-method) and reducing power of alcoholic extracts. Raw of investigated plants collected from experimental collections of M.M. Gryshko National Botanical Garden of the NAS of Ukraine (Kyiv) and dried for next investigation. Obtained results showed that total content of polyphenols in the above-ground parts of B. orientalis extracts was 52.88 mg g-1 GAE (gallic acid equivalent), phenolic acids-11.29 mg g-1 CAE (caffeic acid equivalent), flavonoids-39.91 mg g-1 QE (quercetin equivalent), antioxidant activity-8.94 mg g-1 TE (Trolox equivalent) and reducing power of extracts-184.59 mg g-1 TE (Trolox equivalent). Total content of polyphenols in the above-ground parts of S. hispanica plants was 60.16 mg g-1 GAE, phenolic acids-20.71 mg g-1 CAE, flavonoids-36.24 mg g-1 QE, antioxidant activity-5.35 mg g-1 TE and reducing power of extracts-125.40 mg g-1 TE. Also, total content of polyphenols in the roots of B. orientalis extracts was 9.75 mg g-1 GAE, phenolic acids-1.73 mg g-1 CAE and reducing power of extracts-138.70 mg g-1 TE. Root extracts of S. hispanica had total content of polyphenols of 10.87 mg g-1 GAE, phenolic acids-2.62 mg g-1 CAE and reducing power of extracts-110.96 mg g-1 TE. Flavonoids and antioxidant activity in the root extracts of both species weren't determined. The antimicrobial activity of alcoholic extracts of two investigated species was tested against 8 microorganisms by disc diffusion method. It was found that higher activity against microbial strains had alcoholic extracts of B. orientalis roots.
