Abstract The impacts of a low temperature plasma treatment on wheat seed germination and field growth were investigated using a plasma system about the first generation (T0), the second generation (T1) and the third generation (T2). Untreated wheat seeds were set as the control (CK). Plasma treatments of 80 W and 100 W were employed during the experiments. Germination characteristics, seedling growth parameters, biological characters and yield components were measured following the plasma treatments. The wheat seed germination index, plant height, tiller, growth and grain number obviously changed significantly after the low-temperature plasma treatment. Furthermore, the moderate-intensity plasma had an active impact on wheat seed germination and growth. The results showed that the theoretical yield of T0 significantly increased by 8.92% and 8.14%, while the actual yield increased by 8.12% and 6.10% compared with untreated. The theoretical yield of T1 increased by 1 5.69% and 6.62%, while it increased by 3.70% and 0.45% for T 2. The actual yield of T increased by 5.75% and 4.94%, while it increased by 3.81% and 0.82% for T2. Plasma treatment exhibited the following trend of increasing: T0 > T1 > T2 > CK. We conclude that the effects of low-temperature plasma on the biological characteristics and yield components 1 to T2. of wheat seeds exhibited a consistent trend from T 0 to T Keywords Low-temperature plasma · Wheat seeds · Biological characters · Yield components

Plasma Chemistry and Plasma Processing
Introduction Plasma can be divided into low-temperature plasma (LTP) and high-temperature plasma. LTP has become a widely popular seed treatment, due to its ability to function under lowtemperature conditions without causing thermal damage to the seed surface, as well as activating seed vigor before sowing [1, 2]. Volin et al. [3] determined germination effects to vary depending on different conditions for plasma treated seeds. Meng et al. found that treatments that use different types of gases exert distinct impacts on seed growth due to differing responses to radiation [4, 5]. Plasma treatment have been observed to increase the growth rate of numerous seed types, including radish seeds [6, 7], wheat, oats [8, 9], as well as the dry weight of radish. In order to obtain the optimum treatment in terms of wet germination and grow
