为促进盐地碱蓬〔Suaeda salsa （Linn.） Pall.〕黑色种子发芽和幼苗生长，以盐地碱蓬品种‘沿海碱蓬1号’（‘Yanhai Jianpeng No. 1’）为材料，以未经过冷等离子体处理（0 W）的种子为对照，对100、200、300、400和500 W冷等离子体处理3 min后‘沿海碱蓬1号’黑色种子部分发芽指标及幼苗叶片生理指标进行比较，并对处理功率与各指标进行相关性分析。结果表明：各处理组的发芽率、发芽势、发芽指数、活力指数、苗长、根长、可溶性糖含量和超氧化物歧化酶活性以及100、200和300 W处理组的过氧化氢酶活性均显著（P＜0.05）高于对照组，而各处理组的平均发芽时间、丙二醛含量和过氧化物酶活性以及400和500 W处理组的过氧化氢酶活性均显著低于对照组。冷等离子体处理功率与发芽势、根长和可溶性糖含量显著正相关，与丙二醛含量显著负相关。综合分析认为，100~500 W冷等离子体处理3 min可有效促进盐地碱蓬黑色种子发芽，增强幼苗的抗氧化能力，其中300 W冷等离子体处理效果最佳。

 To promote the germination and seedling growth of black seeds of Suaeda salsa （Linn.） Pall., the cultivar ‘Yanhai Jianpeng No. 1’ of S. salsa was used as material, and the seeds without cold plasma treatment were used as the control, some germination indexes of black seeds and leaf physiological indexes of seedlings of ‘Yanhai Jianpeng No. 1’ were compared after 100, 200, 300, 400, and 500 W cold plasma treated for 3 min, and the correlation analysis was conducted between the treatment power and each index. The results show that the germination rate, germination potential, germination index, vigor index, seedling length, root length, soluble sugar content, and superoxide dismutase activity in all treatment groups, as well as the catalase activity in 100, 200, and 300 W treatment groups, are significantly higher （P<0.05） than those in the control group, while the mean germination time, malonaldehyde content, and peroxidase activity in all treatment groups, as well as the catalase activity in 400 and 500 W treatment groups, are significantly lower than those in the control group. The treatment power of cold plasma shows significant positive correlations with the germination potential, root length, and soluble sugar content, while it exhibits a significant negative correlation with the malonaldehyde content. The comprehensive analysis suggests that 100-500 W cold plasma treatment for 3 min can effectively promote the black seed germination of S. salsa and enhance the antioxidant capacity of seedlings, among which, 300 W cold plasma treatment has the best effect.
