Centaurea cyanus, belonging to the Asteraceae family, is an arable weed species encountered mainly in fields with cereals, sugar beet, and maize. The high genetic variability of C. cyanus has been recently reported; however, little known about its sequence context herbicide resistance. resistance was found against acetolactate synthase (ALS) inhibitors, but no ALS information concerning mechani...

The impact of the size and shape of a selected group of herbs (dried juniper berries – Juniperus communis, dry blueberries – Vaccinium myrtillus, petals of cornflower – Centaurea cyanus) on the value of the volatility coefficient, the coefficient of sphericity and the critical speed was analysed in the presented research. A laboratory anemometer to measure the speed of air was used. The determi...

ABSTRACT Edible flowers are rich in bioactive compounds and pigments that on increasing demand nutraceutical, medicinal, food, cosmetic dyeing industries. This study evaluated the anthocyanins, phenolics antioxidant activity of eight edible ( Bellis perennis L., Centaurea cyanus Dianthus carthusianorum Lavandula angustifolia Mill., Primula vulgaris Huds., Rosa canina pendulina L. Viola odorata ...

Cantaurea maculosa, the spotted knapweed, is a common wild plant, aqueous extracts of which demonstrate antibacterial activity against gram-positive and gram-negative bacteria. Of 13 species of Centaurea screened for antibacterial activity by Osborn (1943), only three yielded extracts that were inhibitory to the growth of Staphylococcus aureus and none was active against Escherichia coli. Our C...

Mucorales comprises fungi commonly isolated as saprobes from soil, dung, stored grains and plants. Although these fungi have been studied in several countries, there are relatively a few reports of them in semi-arid areas. Therefore, the aims of the present study were to assess and compare the Mucorales communities in dung from different species and breeds of herbivores in the semi-arid of Pern...

The blue pigment of cornflower, protocyanin, has been investigated for a long time, but its precise structure was not entirely explained until recently. The molecular structure of the pigment was recently shown to be a metal complex of six molecules each of anthocyanin and flavone glycoside, with one ferric iron, one magnesium and two calcium ions by X-ray crystallographic analysis. The studies...

Experimental evidence on the bio-ecological effects of microplastics terrestrial plants is still lacking. In this study, we hypothesized that soil polluted with polyvinyl chloride (PVC) microparticles can negatively influence plant traits, photosynthetic efficiency and phenology two weeds but different strength in relation to species’ life traits. Therefore, conducted an experiment a common gar...
