Abstract :
The objective of the present study was to determine the effects of non-thermal atmospheric plasma (NTAP)
on physiological features of black cumin seeds. Black cumin seeds were divided into 4 groups, one control
group and three experimental groups. The experimental groups were exposed to NTAP for 5, 10, and 20
minutes, respectively. Then the seeds of the experimental and control groups were grown for 21 days.
Subsequently, total sugar levels, total flavonoids, malondialdehyde (MDA) levels, and the activities of
superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) enzymes were evaluated.
Results showed that the concentration of sugar, total flavonoids, and total proteins in the experimental
groups increased significantly compared to the control group. SOD, CAT, and APX activity decreased in all
NTAP- treated plants significantly compared to the control group. It can be concluded that black cumin seeds
treated with non-thermal atmospheric plasma may increase plant resistance by changing the enzymatic
antioxidant system.
