Investigation of the effect of pre-sowing electrical stimulation of winter rapeseed on its spectral-luminescent properties

The samples of rapeseed oil obtained by dissolving ground rapeseed in hexane (chemical extraction method) were studied. Portion of sample seeds was left unthreatened as the reference, another was treated by an electrostatic field at intensity of E = (0,5 divided by 2,5) kV/cm and t = 30c. The behavior of fluorophores of solutions of rapeseed oil in hexane, namely, tocopherol, phenol, fatty acids, vitamins and pigments provided information on the chemical composition and cell structure of the studied seeds. It was established that the fluorophores of solutions of rapeseed oil in hexane prepared from unthreatened seeds and seeds treated at an electrostatic field intensity of E = (0,5 divided by 2,5) kV/cm and t = 30c are characterized by identical spectral-luminescent properties. The spectral-luminescent properties of phenols, tocopherols, fatty acids, vitamins and pigments of rapeseed oil obtained from the untreated and treated seed, were identical, regardless of the modes of its pre-sowing treatment. Presowing electric treatment of rapeseed by an electrostatic field in this mode does not cause changes in the chemical composition and structure of the cell, its fatty acid composition and the content of vitamins and pigments.
