Influence of irrigation conditions in the germination of plasma treated Nasturtium seeds

Abstract Plasma treatments had emerged as a useful technique to improve seed germination. In this work we investigate the influence of different irrigation conditions and plasma treatments on the germination of nasturtium seeds. During plasma treatment, seeds experience a progressive weight loss as...
