Pre-sowing seeds stimulation by UV-C and X-ray irradiation on the content of antioxidants in inflorescence plants genotypes Matricia chammomila L.

Abstract

The differences in the dynamics of the flavonoids and phenols content in plants of eight genotypes of matricaria in the control and at presowing UV-C and X-ray irradiation of seeds were studied. Groups of genotypes by the stimulating effect on the content of antioxidants were determined mainly by UV-C irradiation, as well as groups with a significant increase in the content of antioxidants during X-ray irradiation have been identified. A high significant correlation (R = 0.84) between stimulation of flavonoid synthesis by X-ray irradiation and the level of these antioxidants in the control group is shown. Above average (R = 0.64), but insignificant, the correlation is observed between the level of flavonoids in UV-C stimulation and the level of these antioxidants in the control group. No correlation was found between the content of phenols in the control group and the increase of this indicator after irradiation.
