Cuminum cyminum is an annual and herbaceous plant with medicinal and aromatic properties belonging to the Apiaceae family. Reactive nitrogen and oxygen species present in cold plasma have significant influence on seed germination and seedling growth. This study was aimed to investigate the effect of plasma at different exposure time on germination percentage and growth parameters of cumin seeds. Seed germination was enhanced by 43.24 % with amplified vigor index and dry weight at 3 min (2 kV) cold plasma exposure, whereas 15.5 %, 41.79 %, and 34.5 % increment in total chlorophyll content, root, and shoot length respectively was also obtained when compared with control. Optical emission spectroscopy (OES) analysis of discharge plasma justified the positive influence of specific reactive species on physiological changes in cumin seeds. Thus, cold plasma could be promising technique to enhance the germination of medicinal and aromatic seeds.

孜然是一种一年生草本植物，具有药用和芳香性，隶属于A科。冷血浆中存在的反应性氮和氧种类对种子发芽和幼苗生长有重要影响。本研究旨在探讨不同暴露时间下血浆对小茴香种子发芽率和生长参数的影响。在低温（3 kV）（2 kV）下暴露时，活力指数和干重增加，种子发芽增强43.24％，而总叶绿素含量，根和茎长分别增加15.5％，41.79％和34.5％。与对照相比。放电等离子体的光学发射光谱（OES）分析证明了特定反应物种对小茴香种子生理变化的积极影响。从而，
