Aquatic Plants in Ponds at the Brdo Estate (Slovenia) Show Changes in 20 Years.

Ponds are important habitats for aquatic plants and other biota, particularly in regions where the quality of aquatic ecosystems is deteriorating or even disappearing. Ponds provide refuge for many species and serve as foraging places for others. The ponds studied are located in the Brdo Estate and are under special protection to maintain their educational and other ecosystem services.

Differences in Phytobenthic Diatom Community between Natural and Channelized River Sections.

The structure of phytobenthic diatom communities was studied to reveal differences between natural and channelized river sections in Slovenia.

Contrasting Dynamics of Littoral and Riparian Reed Stands within a Wetland Complex of Lake Cerknica.

This contribution discusses the use of field measurements and remotely sensed data in an exploration of the effects of environmental parameters on the riparian and littoral stands of the common reed () in an intermittent wetland in Slovenia.

Molecular Shield for Protection of Buckwheat Plants from UV-B Radiation.

Tartary buckwheat ( (L.) Gaertn.) and common buckwheat ( Moench) are adapted to growing in harsh conditions of high altitudes.

Adaptative Responses of Common and Tartary Buckwheat to Different Altitudes.

Environmental conditions at different elevations are harsher at higher elevations and impose constraints upon plants. The response of common and Tartary buckwheats to environmental conditions at elevations between 300 and 1180 m above sea level (asl) was studied. In common buckwheat, grown at the highest elevation, there was an increased investment in secondary metabolism, and decreased investment in primary metabolism, since the production of UV-absorbing compounds was enhanced while the amounts of chlorophylls and carotenoids decreased.

Silicon Mitigates Negative Impacts of Drought and UV-B Radiation in Plants.

Due to climate change, plants are being more adversely affected by heatwaves, floods, droughts, and increased temperatures and UV radiation. This review focuses on enhanced UV-B radiation and drought, and mitigation of their adverse effects through silicon addition. Studies on UV-B stress and addition of silicon or silicon nanoparticles have been reported for crop plants including rice, wheat, and soybean.

Breeding Buckwheat for Increased Levels and Improved Quality of Protein.

Tartary buckwheat ( (L.) Gaertn.) and common buckwheat ( Moench) are important sources of proteins with balanced amino-acid compositions, and thus of high nutritional value.

Significant Accumulation of Iodine and Selenium in Chicory ( L. var. Hegi) Leaves after Foliar Spraying.

The interactions between the uptake of selenium (as selenite and selenate) and iodine (as iodate and iodide) by red chicory ( L. var. Hegi) and their effects on selected morphological and physiological characteristics were investigated.

Breeding Buckwheat for Increased Levels of Rutin, Quercetin and Other Bioactive Compounds with Potential Antiviral Effects.

Common buckwheat ( Moench) and Tartary buckwheat ( (L.) Gaertn.) are sources of many bioactive compounds, such as rutin, quercetin, emodin, fagopyrin and other (poly)phenolics.

Response of Pumpkin to Different Concentrations and Forms of Selenium and Iodine, and their Combinations.

The elements selenium (Se) and iodine (I) are both crucial for the normal functioning of the thyroid. Biofortification with these elements is particularly feasible in areas where they show a deficit. Iodine and selenium can have positive effects on different plants when applied at the correct concentrations.

Water Shortage Strongly Alters Formation of Calcium Oxalate Druse Crystals and Leaf Traits in .

Common buckwheat ( Moench) is a robust plant with high resistance to different environmental constraints. It contains high levels of calcium oxalate (CaOx) druse crystals, although their role remains obscure. The objective was to examine the effects of water shortage on plant biomass partition and leaf traits and formation of CaOx druse crystals in common buckwheat.

Background: The biofortification of crops can counteract human diseases, including selenium (Se) and iodine (I) deficiencies in the diet. Little is known about the effects of combinations of Se and I on microgreens and seeds, or on their accumulation in these tissues. The present study aimed to evaluate Se (SeO , SeO ) and I (I , IO ) biofortification of common buckwheat microgreens and seeds with respect to the effects of the addition of Se, I and Se + I on yield and on physiological and biochemical characteristics.

The temperature threshold for the transformation of rutin to quercetin in Tartary buckwheat dough.

The aim was to determine conditions under which rutin can be retained during production of Tartary buckwheat (Fagopyrum tataricum) dough. Tartary buckwheat flour was hydrothermally treated by mixing with water at 25, 40, 60, 80 and 95 °C, with unprocessed Tartary buckwheat flour as control.

Calcium oxalate druses affect leaf optical properties in selenium-treated Fagopyrum tataricum.

Plants of the genus Fagopyrum contain high levels of crystalline calcium oxalate (CaOx) deposits, or druses, that can affect the leaf optical properties. As selenium has been shown to modify the uptake and accumulation of metabolically important elements such as calcium, we hypothesised that the numbers of druses can be altered by selenium treatment, and this would affect the leaf optical properties.
