Germination rates were higher with magnetic field applications than control group. Many studies showed that 125 mT and 250 mT magnetic treatment produced a biostimulation on the initial growth stages and an increased the germination rate of several seeds such as rice, wheat and barley [18, 19, 21-23].
What is the role of magnetic field in sunflower seeds?
Magnetic field biostimulation plays a significant role in enhancing the germination of seeds and increasing the metabolic rate. The low magnetic field effect for long exposure time and its effect on antioxidant profiling have not been studied. Therefore, in the recent findings, the static magnetic field’s impact on sunflower seeds subjected to ...
What is the most effective tocopherol for sunflower seed?
HPLC analysis of tocopherol from the most effective sunflower seed variety FH620 is shown in Figure 2. Vitamin E is a major lipophilic antioxidant that has remarkable scavenging activity due to alkoxyl and peroxyl radicals. It protects other plant tissues and the cell membrane from oxidation and helps protect from damage caused by free radicals.
What is FTIR in sunflower seeds?
Fourier Transform Infrared Spectroscopy (FTIR) spectra have been used to evaluate the structural changes and functional groups of sunflower seedling organic compounds. The average wavelength of the spectrum was 1000–3500 cm −1, as shown in Figure 1. The FTIR profiling of untreated sunflower seed extracts shows different functional groups, such as the characteristic absorption band at a broad signal of 3500 cm −1 (N-H stretching from amine superimposed to C-H stretching), while C-H (Arene) stretching at 3000 cm −1 has been observed. In the seed extract, the abovementioned data indicated the separation of C=O into two peaks. The carboxylic group O-H expanding was overlapped by a 2500 cm −1 spectral range that emerged from the alkane group as a band comparable to C-H bending. The FTIR seed extract spectrum showed negligible variations compared to the control group at the most efficient (50 mT/45 min) magnetic field strength (Figure 1 ). In Table 4, the identified organic groups were described.
Does magnetic biostimulation affect sunflower seeds?
Presown magnetic biostimulation of sunflower seeds has a significant effect on germination parameters. Because of magnetic treatment, the mobilization of stored protein contents plays a significant role in antioxidant activity.
