| Popis: | This paper describes an investigation of plasma influence on the germination rate of brown mustard seeds (Brassica juncea L.). It was found that five pulses of a nanosecond microspark have a suppressing action increasing the time of the seeds germination by 5 h; the plasma influence and UV-radiation of the nanosecond surface discharge with the frequency of 1 Hz for the course of 15 min being at a distance of 25 mm from the surface of the seed have a stimulating action on it reducing the germination time by 3 h; a combined treatment using the discharges of both types showed that germination rate may look as two-pulse mode. Repeated experiments confirmed this conclusion. Visual observation of the seeds after the UV-radiation and plasma treatment revealed cracks on the seed coats. The cracks significantly increase moisture penetration into the coat. |
