Abstract

Aim: The study was carried out to Plasma treatment of seeds at atmospheric pressure as a new technology, through its activation of seed endogenous substances, so that crops improve disease resistance, thereby increasing yield.

Materials and Methods: Using plasma seed processor to treat the seeds of green bean (Jiadouwang), the test was carried out with different doses (200 mA~1600 mA).

Results: The results showed that the growth and development of green bean were significantly improved by comparing different plasma doses treated with the untreated CK. and the treatment current (dose) of 1000 mA、1200mA and 1400 mA of plant traits were significantly changed. The plasma treatment with different doses (current 200 mA~1600mA) can promote the yield of green beans, especially, the yield effect of the appropriate dose (1000 mA) was extremely significant, the plasma current treatments 600 mA、800mA、1400mA had a significant effect on the yield of green beans. The trend prediction of single pod yield was basically consistent with the actual test data. The disease resistance of green beans after proper dose (600 mA~1600 mA) plasma treatment was better than that of untreated CK.

Conclusion: In brief, the effect of different doses of plasma treatment on the biological properties of green bean was different. The plant traits of green bean by proper plasma treatment were significantly improved compared with the control (CK), and the disease resistance of treated green bean was also better than that of untreated (CK). The yield of green bean in the eight treated groups could be improved by plasma treatment with different dosage.
