Effect of in–package cold plasma treatments on the quality of minimally processed apples.
(2023)Cold plasma technology is being increasingly used for food preservation and, incipiently, for minimal processing of fruit. Therefore, the objective of this work was to study the effect of in-package cold plasma (generated ... -
Effects of non-thermal plasma technology on Diaporthe longicolla cultures and mechanisms involved.
(2021-01-05)BACKGROUND: The Diaporthe/Phomopsis complex (D/P) is a group of soybean seed-borne fungi. The use of chemical fungicides, either for seed treatment or during the crop cycle, is the most adopted practice for treating fungal ... -
Effects of non–thermal plasmas on seed-borne Diaporthe/Phomopsis complex and germination parameters of soybean seeds.
(2018)Diaporthe/Phomopsis (D/P) is a complex of seed-borne fungi that severely affects soybean (Glycine max (L.) Merrill), one of the most important crops worldwide. Non-thermal plasma treatment is a fast, economic and ... -
Enhancement of soybean nodulation by seed treatment with non–thermal plasmas
