germination of soybean seeds exposed to the static alternating magnetic field and Algal Extract
Engineering in Life Sciences, 2019Co-Authors: Izabela Michalak, Sylwia Lewandowska, Katarzyna Niemczyk, Jerzy Detyna, Henryk Bujak, Pelin Arik, Annika BartniczakAbstract:In the present study, the effect of the static and alternating magnetic field applied individually and in combination with an Algal Extract on the germination of soybean seeds (Glycine max (L.) Merrill) and chlorophyll content was examined. The exposure time of seeds to the static magnetic field was 3, 6, and 12 min, whereas to the alternating magnetic field was 1, 2.5, and 5 min. The static magnetic field was obtained by means of a permanent magnets system while the alternating magnetic field by means of magnetic coils. Algal Extract was produced from a freshwater macroalga-Cladophora glomerata using ultrasound homogenizer. In the germination tests, 10% Extract was applied to the paper substrate before sowing. This is the first study that compares the germination of soybean seeds exposed to the static and alternating magnetic field. The best effect on the germination and chlorophyll content in seedlings had synergistic action of the static magnetic field on seeds for 3 min applied together with the Extract and alternating magnetic field used for 2.5 min. It is not possible to clearly state which magnetic field better stimulated the germination of seeds, but the chlorophyll content in seedlings was much higher for alternating magnetic field.

Influence of the Static Magnetic Field and Algal Extract on the Germination of Soybean Seeds
Open Chemistry, 2019Co-Authors: Sylwia Lewandowska, Izabela Michalak, Katarzyna Niemczyk, Jerzy Detyna, Henryk Bujak, Pelin ArikAbstract:AbstractThis study examines the effect of a separate static magnetic field (SMF) and Algal Extract and their synergistic effect on soybean seeds germination. To our knowledge, this is the first time these kinds of factors were used for the biostimulation of soybean seeds germination. Soybean – Glycine max (L.) Merrill variety ‘Merlin’ was used in the present study. The exposure of seeds to the magnetic field was applied for 3, 6 and 12 min. The Algal Extract, produced from a freshwater green macroalga – Cladophora glomerata using an ultrasonic homogenizer, was used directly to the paper substrate at a dose of 10%. The highest germination ability of soybean seeds was observed in a group, where the magnetic field (12 min.) was used together with 10% of Algal Extract. However, it was very low – only 21%, which may have resulted from the seed dormancy. Future experiments on soybean seeds are required to confirm the stimulation effect of the magnetic field (various induction values) and Algal Extract on seeds germination.

The Influence of pH of Extracting Water on the Composition of Seaweed Extracts and Their Beneficial Properties on Lepidium sativum.
BioMed research international, 2017Co-Authors: Katarzyna Godlewska, Izabela Michalak, Łukasz Tuhy, Katarzyna ChojnackaAbstract:Baltic seaweeds were used to obtain aqueous Extracts (E) through changing initial pH of deionised water added to Algal biomass (EpH3·H2O, EpH7·H2O, and EpH10·H2O) and through changing pH of the mixture of algae and deionised water (EpH3, EpH7, and EpH10). Algal Extracts were characterized in terms of the concentration of polyphenols and micro- and macroelements. The highest concentration of polyphenols was determined in Extract EpH3 and the lowest in Extract EpH10·H2O. It was found that the obtained Extracts had similar concentrations of elements (except EpH3). The phytotoxicity of Algal Extracts (0.5, 2.5, and 10%) was examined in the germination tests on Lepidium sativum. No phytotoxic effects were observed. It was found that they had beneficial effects on the cultivated plants (length and weight). The best biostimulant effect was observed in the groups treated with EpH3 (2.5%), EpH7 (2.5%), and EpH7 (10%). The dry weight of plants was similar in all the groups. Algal Extract also improved the multielemental composition of plant. The greatest concentration of total chlorophyll in plants was obtained by using Extract EpH10·H2O, 0.5%. These results proved that Algal Extracts have high potential to be applied in cultivation of plants.

Seaweed Extract by microwave assisted Extraction as plant growth biostimulant
Open Chemistry, 2015Co-Authors: Izabela Michalak, Łukasz Tuhy, Katarzyna ChojnackaAbstract:AbstractMicrowave Assisted Extraction (MAE) was used to obtain aqueous Extracts of Baltic seaweeds. Three different temperatures: 25, 40, 60°C were examined. Algal Extracts were characterized in terms of polyphenols, micro- and macroelements, lipids content and antibacterial properties. This is the first study that examines the effect of Algal Extract obtained by MAE in plant cultivation. The utilitarian properties were checked in the germination tests on Lepidium sativum for three dilutions of Extract (0.5, 2.5 and 10%). Results showed that the content of polyphenols in Extracts decreased with temperature, whereas the content of micro- and macroalements increased with temperature. The aqueous Extracts did not contain fatty acids and did not show inhibitory effect on Escherichia coli and Staphylococcus aureus. Germination tests showed that plants in the experimental groups with an optimal concentration of Extract had a higher height, weight, chlorophyll and micro- and macroelement content than plants in the control group. The Algal Extracts did not significantly influence the morphology of plants as shown in SEM pictures. Results show that Algal Extracts obtained by MAE have the highest potential applied in agriculture as biostimulants.
