What is Effect of green technologies of cold plasma and airborne ultrasound wave on the germination and growth indices of cumin ( Cuminum cyminum L.) seeds about?

## Abstract Current research is considered to study the effect of nonthermal physical field technologies of atmospheric cold plasma (CP) and ultrasound waves (US) on the germination and seedling indices of cumin seeds. In this regard, different drying strategies were planned in a single and combined form using a lab‐scale cold plasma unit and ultrasound‐assisted air dryer. Various duration of CP pretreatment (CPt: 0, 15, and 30 s), ultrasound power (P: 0, 60, 120, and 180 W), and air temperature (T: 30, 35, and 40°C) were practiced to investigate the changes in germination traits and microstructure characteristics of cumin seeds. It was found that CP pretreatment and ultrasound treatment in a single form significantly increased germination percentage, germination index, and germination rate as well as seeding vigor of cumin seeds. The morphological alteration in the surface of the seeds, which modifies the seed surface hydrophilicity and accelerates water uptake, may be the leading cause of CP and US‐induced modification in the germination power. The highest stimulatory effect belonged to the combined application of cold plasma and ultrasound wave when the cumin seeds were treated
