THE EFFECT OF DCSBD PLASMA TREATMENT ON WHEAT SEED GERMINATION AND Α-AMYLASE ENZYME ACTIVITY

Abstract

In this paper, we studied the effects of plasma treatment of wheat seeds on germina-
tion and α-amylase enzyme activity. In order to characterize the plasma the optical properties of the die-
lectric coplanar surface barrier discharge (DCSBD) were investigated. The results of optical emission
spectroscopy showed the presence of molecular nitrogen bands in the emission spectrum of the DCSBD,
namely, the second positive (N2 (C-B)) and the first negative (N2 + (B-X)) systems, and low-intensity
OH and NO lines. Also, in order to determine the temperature at different supplied powers, as well as to
exclude thermal effects of a dielectric coplanar surface barrier discharge, further studies on the pro-
cessing of agricultural crops and polymeric materials were carried out to measure the surface tempera-
ture of the experimental setup. These measurements have shown that with further research on the pro-
cessing of polymers and crops, thermal effects can be excluded.The results showed that the plasma of
DCSBD has a positive effect on germination rate of wheat seed sand α-amylase enzyme activity during
the growth. Also, the biometric indicators of germinated seeds were significantly higher after the plasma
processing.
