Effects of Low-temperature Plasma on Characteristics of Wheat Seedling

Abstract:

The non-ionizing radiation processing with 20 s was treated on wheat seeds by using low-temperature plasma (LTP). The effect of the proposed technology on seed germination and seedling growth was analyzed. The effects of different intensities of LTP on wheat seeds (45 d after treated by LTP) were investigated to determine the optimal conditions. The germination energy and germination rate were obtained. Also, the samples were sowed in field to investigate the characteristics of seeds. The results showed that the germination energy and germination rate increased by 11.25% and 5.56% respectively for the treatment intensity of 80 W. The green weight, dry weight, root length and maximum tillers of seeds in double ridge stage were increased by 13.02%, 6.00%, 15.20%, and 38.46% compared with contrast.
