Kelp (Laminaria digitata) uses iodide as a unique inorganic antioxidant to protect its surface and apoplastic space against reactive oxygen species such ozone, hydrogen peroxide superoxide, with implications for atmospheric marine chemistry well regional climatic processes. If kelp is covered by seawater, this results in leaching into surrounding sea water. In study, the influence of kelps Lami...

Seaweeds are highly perishable foods due to their richness in nutrients. High pressure processing (HPP) has been applied for extending the shelf life of fresh seaweeds but there is no information on effect HPP bacterial diversity seaweeds. The culturable bacteria six species edible (green Codium fragile and Ulva lactuca, brown Himanthalia elongata, Laminaria ochroleuca Undaria pinnatifida, red ...

Within the genus Centaurea L., polyploidy is very common, and it believed that, as to all angiosperms, was key in history of its diversification evolution. tentudaica a hexaploid from subsect. Chamaecyanus unknown origin. In this study, we examined possible autopolyploid or allopolyploid origin using allozymes sequences three molecular markers: nuclear-ribosomic region ETS, low-copy genes AGT1 ...

Thermal tolerance is often interpreted as a species-wide thermal niche in the absence of studies focusing on adaptive potential populations to exhibit differential tolerance. Thus, considering intraspecific plasticity, local adaptation or both between along distributional gradients when interpreting and predicting species responses warming imperative. Removing effect environmental histories by ...

We have studied hybrids between Rubus idaeus and various members of R. sect. Corylifolii, primarily in Sweden. With the help DNA-ploidy level determinations using flow cytometry microsatellite DNA analysis over 500 samples, we show that material can be divided into four stable apomictic species (belonging to subsect. Subidaei) a large number primary hybrids. Stable recognised by distribution is...

ABSTRACT Cover crops can provide suppression of weeds and together with chemical control make the proper management in agricultural areas. The objective this study was to evaluate effect cover crop cultivation during off-season on weed development a no-tillage area. experimental design randomized blocks scheme six treatments four replications. were: fallow (control), millet (Pennisetum glaucum)...
