Abstract

Continuous changing of drought frequency and duration affects crop production. Among many techniques used to improve crop growth, the use of cold atmospheric plasma (CAP) has been popular in recent years. However, limited knowledge is available to understand the action of CAP on the seeds that help in germination and growth enhancement. This work aims to determine the effect of CAP on the barley seed coat using electron paramagnetic resonance (EPR). We observed that EPR intensity for Fe3+ increases with plasma treatment time. However, the intensity of the stable organic radical decreases for higher plasma treatment. We suggest that reactive species generated by CAP treatment for short time intervals can increase the radical contents in the barley seeds. That may accelerate the plant hormone or other biological processes to improve the germination, seedling growth,

等离子体处理对大麦种子顺磁性自由基强度的影响:EPR研究

干旱发生频率和持续时间的持续变化影响着农作物生产。近年来，低温大气等离子体(CAP)技术在许多作物生长改良技术中得到了广泛应用。然而，对CAP对种子萌发和生长促进作用的了解有限。本工作旨在利用电子顺磁共振(EPR)技术确定CAP对大麦种皮的影响。我们观察到Fe3+的EPR强度随着血浆处理时间的增加而增加。然而，稳定的有机自由基的强度降低了较高的等离子体处理。由此可见，短时间CAP处理产生的活性种可以提高大麦种子中自由基的含量。这可能会加速植物激素或其他生物过程，以改善发芽，幼苗生长，

期刊介绍： Technology has always played an important role in medicine and there are many journals today devoted to medical applications of ionizing radiation, lasers, ultrasound, magnetic resonance and others. Plasma technology is a relative newcomer to the field of medicine. Experimental work conducted at several major universities, research centers and companies around the world over the recent decade demonstrates that plasma can be used in variety of medical applications. It is already widely used surgeries and endoscopic procedures. It has been shown to control properties of cellular and tissue matrices, including biocompatibility of various substrates. Non-thermal plasma has been demonstrated to deactivate dangerous pathogens and to stop bleeding without damaging healthy tissue. It can be used to promote wound healing and to treat cancer. Understanding of various mechanisms by which plasma can interact with living systems, including effects of reactive oxygen species, reactive nitrogen species and charges, has begun to emerge recently. The aim of the Plasma Medicine journal will be to provide a forum where the above topics as well as topics closely related to them can be presented and discussed. Existing journals on plasma science and technology are aimed for audiences with primarily engineering and science background. The field of Plasma Medicine, on the other hand, is highly interdisciplinary. Some of prospective readers and contributors of the Plasma Medicine journal are expected to have background in medicine and biology. Others might be more familiar with plasma science. The goal of the proposed Plasma Medicine journal is to bridge the gap between audiences with such different backgrounds, without sacrificing the quality of the papers be their emphasis on medicine, biology or plasma science and technology.
