摘要

在本研究中，对等离子活化水浸泡后的种子进行了生理、萌发和幼苗生长的分析。研制了介质阻挡放电等离子体滴管对废水进行处理。在37、43或49千伏的峰值电压下，将绒红雀种子浸泡在水等离子体中，并在渗吸过程中进行监测。在吸收种子的同时，测量了渗出液的pH值、电导率和UV-Vis吸收。种子在吸胀过程中释放物质，pH值维持在5 ~ 6之间。这一事实可以作为控制植物生理和种子萌发的策略。结果表明，在49 kV电压下处理的水具有较高的发芽率和种子活力。讨论了解释这种效应的生理方面及其对发芽反应的影响。关键词:

Effect of Plasma-Activated Water on Soaking, Germination, and Vigor of Erythrina velutina Seeds

: In this study, physiology, germination, and seedling growth of seeds were analyzed after immersion in plasma-activated water. A dielectric barrier discharge (DBD) plasma dripper was developed to treat the water. Erythrina velutina seeds were immersed in water plasma-activat-ed at a peak-to-peak voltage of 37, 43, or 49 kV and monitored during imbibition. While the seeds were imbibing, pH, electrical conductivity, and UV-Vis absorption of the exudate were measured. The seeds released substances during imbibition, maintaining pH between 5 and 6. This fact may be used as a strategy to control plant physiology and seed germination. It was observed that water treated at a voltage of 49 kV presented higher germination rates and seed vigor. Physiological as-pects that explain this effect and its consequences on germinative response are discussed. KEY WORDS:

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.
