# Soybean Germination Response to Algae Extract and a Static Magnetic Field Treatment
## 4 Discussion
[PERSON] et al., showed that commercial extract from _Ecklonia maxima_ (Kelpak) increasedsoybean height, especially when was applied once at a higher concentration (1% vs. 0.7%), which was 35% greater compared to the control [5]. In the case of the application of extract from brown seaweed--_Ascophyllum nodosum_--the shoot height decreased slightly with the increase in extract dose (0.5 g/L (25.3 cm), 1.0 g/L (24.2 cm) and 2.0 g/L (24.1 cm)), but was higher than in the control group (22.7 cm) [56]. In the literature, there are some single examples of the simultaneous treatment of soybean with a mixture of extracts. For example, [PERSON] et al., tested the combination of two extracts, from the seaweed _Ascophyllum nodosum_ and from medicinal herb-clandine (_Chelidonium majus_), both at a dose of 1 g/L [56]. This treatment significantly increased shoot height (13.2%), dry mass (10.7%), and photosynthetic rate (20.3%) compared with the control. This combination also gave better results than when these preparations were used separately. In the present study, we propose the combination of algal extract and physical factors, which are used for pre-sowing treatment of seeds. Scientific works show that the effects of a magnetic field on biological objects placed in are is manifold. We can distinguish electrodynamic interactions with electric currents occurring in organisms, the formation of magnetomechanical effects inside organisms consisting in the orientation of structures with magnetic anisotropy in homogeneous fields and the displacement of ferromagnetic and paramagnetic substances in fields with non-zero gradients, the effect on uncompensated magnetic spins of elements of paramagnetic radicals and free spins of paramagnetic radicals and free spins, the Dorfman effect, consisting in a reorientation of proteins in a magnetostatic field due to the anisotropy of these molecules, and some components of living organisms exhibit magnetostrictive properties. Therefore, there is a possibility of influencing such components as the magnetic field changes the energy of intra- and inter-atomic interactions in living organisms, the sinusoidal alternating magnetic field causes the induction of currents inside living organisms, and the magnetic field may exert an influence on the depolarization of cells [57; 58; 59; 60]. As a result of the penetration of the magnetic field through a living organisms, resonance phenomena can appear, which can take place, not only in the extracellular space, but also in the cell membrane (i.e., also in ion channels) and inside a cell. Due to the presence of water in living organisms, the interaction with a magnetic field in this context is also important. Water that is subjected to an external magnetic field changes its properties--the rate of crystallization, the concentration of dissolved gases, the rate of coagulation, and settling of suspensions increase. In addition, the pH and the wetting capacity change [29; 61; 62; 63]. In many scientific papers, researchers have shown that a magnetic field changed the characteristics of cell membranes, influenced cell reproduction, and caused certain changes in cell metabolism. At the same time, it was pointed out that a magnetic field influences the growth characteristics and various cell functions, such as the amount of mRNA, gene expression, protein biosynthesis, and enzyme activity, and causes changes in various functions at the organ and tissue levels [29; 38; 64]. The hypothesis indicating the importance of paramagnetic properties of some atoms in plant cells and pigments, such as chloroplasts, is extremely interesting. In an external magnetic field, the magnetic moments of these atoms change the direction of the field. The magnetic properties of particles determine their ability to absorb and then convert the energy of a magnetic field into different types of energy and then transfer this energy to other structures in plant cells, activating them in this way [65; 66; 67; 62].
