AB  - Abstract: Polyphenols present in different plant cell organelles increase the resistance of plants to various types of environmental
stresses. We investigated the possibility of increasing the content of bioactive compounds in the seed of yellow
soybean variety Laura. The soybean was treated during vegetation with five products based on plant extracts, on the
assumption of enrichment of plants with various nutrients. Soybean flour extracts were screened spectrophotometrically
for total phenolic content and antioxidant activity. The antioxidant activity was evaluated using three methods. The content
of phenolic acids was determined by HPLC, and the raw protein content was estimated by the Kjeldahl method. Depending
on the treatment, variations in the quantity of individual phenolic acids with up to 90% higher concentration as compared
to the control were observed. Controlled usage of certain plant extracts can increase the concentration of the target group of
bioactive compounds in the samples. The synergistic effect of proteins and phenolic compounds on the antioxidant activity
of extracts was detected. The results of this study are not only important from the aspect of plant resistance to various types
of stress, but also when considering soybean as a functional food.

AB  - 24-epibrassinolide (24-EBL) is plant steroid hormone that can regulate several physiological effects in plants, including promotion of cell growth and induction of heat stress tolerance. The purpose of this work is to investigate the influence of various concentrations of 24-EBL on the dehydration mechanism of seedlings of two maize hybrids (ZP434 and ZP704). Control and treated samples were subjected to isothermal conditions for dehydration processes. The effects of carbohydrates and mineral contents on the possible changes in the dehydration mechanism (from kinetics standpoint) were investigated. Comparing control samples to samples treated with 24-EBL, it was found that different dehydration mechanisms exist The differences arise from the influence of 24-EBL, that causes a significant increase of phosphorus values for ZP704, whilst the reverse was identified for ZP434. It was assumed that the plumule sensitivity to dehydration stress originates from the interaction of water with primary amino groups as cations in polyamines, for lower concentrations of 24-EBL. It was found that the temperature variation (105-130 degrees C) leads to situations where trehalose does not arrive fast enough to "replace the water", because its handicap to binds (by hydrogen bonds) to biomolecules instead of water. It was found that 24-EBL cause changes of carbohydrates properties, which are important for the defense mechanism from environmental stresses. (C) 2018 SAAB. Published by Elsevier B.V.

AB  - Proposed distributed reactivity model of dehydration for seedling parts of two various maize hybrids (ZP434, ZP704) was established. Dehydration stresses were induced thermally, which is also accompanied by response of hybrids to heat stress. It was found that an increased value of activation energy counterparts within radicle dehydration of ZP434, with a high concentration of 24-epibrassinolide (24-EBL) at elevated operating temperatures, probably causes activation of diffusion mechanisms in cutin network and may increases likelihood of formation of free volumes, large enough to accommodate diffusing molecule. Many small random effects were detected and can be correlated with micro-disturbing in a space filled with water caused by thermal gradients, increasing capillary phenomena, and which can induce thermo-capillary migration. The influence of seedling content of various sugars and minerals on dehydration was also examined. Estimated distributed reactivity models indicate a dependence of reactivity on structural arrangements, due to present interactions between water molecules and chemical species within the plant.
