The current status of research on polyphenolic compounds in the berries of edible honeysuckle and their biological effects, including recommended utilization, are reviewed. The major classes of phenolic compounds in the blue berried honeysuckle are flavonols (quercetin, rutin, quercitrin) and flavanes (proanthocyanidins, catechins) and anthocyanins. Cyanidin-3-glucoside and cyanidin-3-rutinoside are considered as major anthocyanidins in edible honeysuckle berries. Such a high level of antioxidant activity in the berries of different species of the genus Lonicera is especially due to the high level of polyphenolic compounds, especially anthocyanins. These berries seem to be prospective sources of health-supporting phytochemicals that exhibit beneficial anti-adherence and chemo-protective activities, thus they may provide protection against a number of chronic conditions, e.g., cancer, diabetes mellitus, tumour growth or cardiovascular and neurodegenerative diseases.
Biochar (BC) properties and its influences within agricultural soil health and environmental ecosystems largely depend on feedstock, residence time and pyrolysis conditions. The organic and inorganic contaminants from soil can be removed using BC as an adsorbent. Additionally, soil amendment with BC is known to improve overall soil quality, microbial and enzymatic activities and soil organic carbon content with nutrient retention and availability. Moreover, one of the great impacts of BC is its capability to capture soil nutrients and sequestrate carbon. The physicochemical properties of biochar could be affected by the feedstocks and pyrolysis conditions (temperature, duration, activation method, etc.). This review paper summarizes the recent research studies on the composition of BC that controls carbon presence in soil, as well as BCs role in improving soil fertility and carbon sequestration, which has not been reported in detail yet. The main finding of the present work revealed that the high pyrolytic temperatures in BC production may have negative impacts on phyto-availability of essential nutrients. Depending on the feedstock raw material and pyrolysis process used for producing BC, it has different capacities for releasing nutrients in the soil. An economically feasible method of producing newly engineered biochar, with more controlled pyrolysis and C-based materials, for suitable agriculture needs to be developed. Further investigation should be carried out to optimize the production procedure and its application to local farming community for sustainable agriculture.
The presented paper deals with monitoring of the ways of selenium (Se) content increase by foliar biofortification with inorganic Se in two varieties of garden pea Pisum sativum L. (Premium, Ambassador) in the conditions of south Slovakia in 2014-2015. The results of experiments show that treatment of plants with two doses of Se concentration (50 g and 100 g Se ha -1 in the form of a sodium selenate anhydrous solution) at the flowering stage significantly increased the total Se content in the seeds of both varieties. Following the results by the consumption of 25 g of dried seeds of peas or 100 g of fresh pea seeds after the biofortification with 100 g Se ha -1 a recommended daily dose of Se in humans may be covered. The significantly positive influence of Se application on the total polyphenols content (TPC) has been confirmed in the both varieties after application of dosage in 100 g Se ha -1 (52% and 33%). A significant increase in the average value of total antioxidant capacity (TAC by DPPH method) in garden pea var. Ambassador was observed after the application of both doses of Se, in case of Premium variety only after application with a 100 g Se ha -1 . Significantly increasing level of TAC by PCL (photochemiluminescence) method was found out only in case of var. Premium.
