Abstract The effect of a flax straw extract on Al corrosion inhibition in strong alkaline solution was studied by using electrochemical measurements, weight‐loss analysis, SEM, and FTIR spectroscopy. Flax added (3 vol %) to the 5 m KOH act as mixed‐type inhibitor. electrochemistry presence solution, morphology surface films formed, mechanism are discussed. Finally, Al–air battery discharge capacity recorded from cell that used electrolyte is substantially higher than with only pure...

It is established that application together with most contributed to stabilization synthesis processes grains wheat. shown conditions optimal water supply ecological stress caused by drought were ammonium sulfate urea zinc. With variants where applied was obtained an increase amount (a + b) compared control...

Accurate assessment of evapotranspiration is essential for crop irrigation planning. In developing countries and given the cost evaluating based on Penman-Monteith equation, this research an attempt to provide a simple equation that depends only temperature estimate serve as alternative method FAO56-PM when air data are available problem missing meteorological solved. Four reference methods (ET) were compared under local climatic conditions El-Nobaria region in northern Egypt. The...

Organic farming is often seen as a sustainable alternative to intensive agricultural systems. The studies conducted in this direction analyze various factors, well their assemblies, and show contradictory results. In order assess the impact of organic method soil cultivation on stable composition most important mineral substances production process, agriculture procedure was implemented with an agrochemical analysis for 12 years. content mobile phosphorus, exchangeable potassium, humus...

Abstract The microhardness of individual morphological structures the hard coat seed Gleditsia triacanthos L. was measured. Measurements were made on transverse and frontal planes. Based differences in hardness two planes, anisotropy revealed. entire has a special which can be compared with hardwood like oat wood. An interesting feature endosperm, comparable to epidermis. Further study processes that occur seeds during imbibition is based obtained data. Mathematical modeling methods are most...

Abstract In a vegetation experiment with soybean plants of the Svapa and Mageva varieties in field bean Geliada Shokoladnitsa varieties, we studied effect pre-sowing treatment seeds these Rizotorfin Epin-extra on nitrogenase activity nodules their ultrastructure. Analysis ultrastructure nodule tissue beans soybeans was carried out flowering phase. It found that highest indices mass number them were Heliada cultivar when treated against background inoculation Rizotorfin, where largest area...

The researchers of Russian State Agrarian University, Moscow Timiryazev Agricultural Academy in 2013-2016 conducted a long-term stationary experiment to study chemical and toxicological properties fiber flax, Voskhod variety, growing on sod-podzolic soil the climate region. Test plots were selected with following crop rotation options: without fertilizers, liming; N100P150K120 (kg a.i./ha), N100P150K120, + manure 20 t/ha, liming. agro-climatic conditions seasons during research years did not...

The effects of humic substances (HS) extracted from flax shives on the fiber and seed yield were examined during 3 years field experiment. HS consists acids—5.3 gL−1 fulvic acids—0.7 applied (6·10–2 concentration, with 300 Lha−1 spraying liquid) in “herring-bone” stage (BBCH 13 growth stage). action was evaluated different climatic conditions three varieties. Application early vegetation plants increased (exceeding control 16.0–28.1%) quality (5% cellulose content), protein oil content seeds...

The impact of agricultural production on the ecological condition vast territories is concern to entire world community. Therefore, concept sustainable development should become basis for training specialists. This article examines transformation system chemical students in Russia, taking into account transition development. study history specialists Russia helped us see causes current crisis and highlights what be preserved. analysis modern needs agro-industrial complex made it possible...

Ensuring the safety of dairy products is one components integrated food safety. The directly related to organization production control carried out when assessing quality water centralized drinking supply system. article discusses feasibility using natural and modified zeolites ensure physical chemical properties Taizhuzgen Shankanai deposits Kazakhstan, possibility their use improve in reconstituted were investigated. efficiency sample purification with zeolite deposit for heavy metal ions...

Bacterial communities associated with medicinal plants are an essential part of ecosystems. The rhizosphere effect is rather important in the cultivation process. purpose study was to analyze oregano (Origanum vulgare L.), peppermint (Mentha piperita thyme (Thymus vulgaris creeping serpillum L.) and sage (Salvia officinalis L.). To estimate quantity 16S bacteria ribosomal genes, qPCR assays were used. compare bacterial communities' structure bulk soil high-throughput sequencing rRNA...

The article presents the data of laboratory results on study effect phytoregulators changes in activity peroxidase enzyme isoforms dry seeds malting barley and during their germination. It was found that use grains increases isoforms.

Abstract In laboratory experiments with resting and germinated seeds of spring wheat, the effect various biological preparations on activity catalase isoforms was studied. experiments, determined at pH = 5.5, 7.0, 8.0 using a phosphate buffer system (1/15 M buffer). The enzyme in dormant wheat grain that underwent post-harvest ripening during germination third, fifth, seventh days method based determining amount hydrogen peroxide dissolved under action enzyme, subsequent titration remaining...

Essential oils (EOs) are of commercial importance for medicine, food, cosmetics, the perfume industry, and agriculture. In plants, EOs, like wax cover, serve as protection against abiotic stresses, such high temperatures water deficiency. The use spraying with exogenous hormones aromatic plants affects accumulation composition volatile compounds, well tolerance to stress. As a result cytokinin treatment 6-BAP (6-benzylaminopurine) (200 mg L-l) Anetum graveolens L. "Uzory" "Rusich" varieties,...
