Effects of cold plasma treatment on soybean (Glycine max L. Merr cv. Zhongdou 40) seed germination and seedling growth were studied. Seeds were pre-treated with 0, 60, 80, 100 and 120 W of cold plasma for 15 s. Results showed that plasma treatments had positive effects on seed germination and seedling growth, and treatment of 80 W had the highest stimulatory effect. Germination and vigor indices significantly increased by 14.66% and 63.33%, respectively. Seed's water uptake improved by 14.03%, and apparent contact angle decreased by 26.19%. Characteristics of seedling growth, including shoot length, shoot dry weight, root length and root dry weight, significantly increased by 13.77%, 21.95%, 21.42% and 27.51%, respectively, compared with control. The seed reserve utilization, including weight of the mobilized seed reserve, seed reserve depletion percentage and seed reserve utilization efficiency significantly improved by cold plasma treatment. In addition, soluble sugar and protein contents were 16.51% and 25.08% higher than those of the control. Compared to a 21.95% increase in shoot weight, the root weight increased by 27.51% after treatment, indicating that plasma treatment had a greater stimulatory effect on plant roots. These results indicated that cold plasma treatment might promote the growth even yield of soybean.
研究了冷等离子体处理对大豆（Glycine max L. Merr cv. Zhongdou 40）种子萌发和幼苗生长的影响。种子分别用0、60、80、100和120 W的冷等离子体预处理15 s。结果表明，等离子体处理对种子萌发和幼苗生长有积极影响，其中80 W处理的刺激作用最强。发芽指数和活力指数分别显著提高了14.66%和63.33%。种子吸水率提高了14.03%，表观接触角降低了26.19%。与对照相比，幼苗生长特性，包括地上部长度、地上部干重、根长度和根干重，分别显著增加了13.77%、21.95%、21.42%和27.51%。冷等离子体处理显著提高了种子储备利用率，包括动员的种子储备重量、种子储备消耗百分比和种子储备利用效率。此外，可溶性糖和蛋白质含量分别比对照高16.51%和25.08%。处理后，地上部重量增加了21.95%，而根重量增加了27.51%，这表明等离子体处理对植物根系的刺激作用更大。这些结果表明，冷等离子体处理可能促进大豆的生长甚至产量。
