Abstract

This study investigates the effect of Gliding Arc Plasma Activated Water (GAPAW) technique on maize germination and growth variables. The effect of GAPAW was evaluated on corn texture, water absorption in Lab conditions, and the pathway Scanning electron microscopy (SEM) analysis of corn seeds was also carry out. Maize seeds were sown 150 m2 and then watered with tap water and with GAPAW. Seed germination, maize growth and chlorophyll content were evaluated in field conditions in a complete randomized block design with four replicates using the Acid Tolerance Population (ATP) variety. Seed texture treated with 15 min of GAPAW making it darker than those of the control (tap water). Pathway SEM analysis showed no change for the 5 min-GAPAW-treated seeds compared to the control but at 15 min-GAPAW significant changes were observed. Germination was 100% at the 15 min-GAPAW compared to the other treatments (0 and 5 min). Stem length, leaf width, collar diameter, chlorophyll content and water uptake have higher values on plants watered with 15 min-GAPAW compared to others treatments. This application could highlight the germination properties of GAPAW in crop production.

滑翔弧等离子体活化水(GAPAW)对玉米(Zea mays L.)的影响种子萌发与生长
研究了滑翔弧等离子体活化水(GAPAW)技术对玉米萌发和生长的影响。在实验室条件下评价了GAPAW对玉米质地、吸水率的影响,并对玉米种子进行了路径扫描电镜(SEM)分析。玉米种子播种150 m2,然后用自来水和GAPAW浇水。以耐酸群体(ATP)品种为试验材料,采用4个完全随机区组设计,在田间条件下评价了种子萌发、玉米生长和叶绿素含量。用GAPAW处理15分钟的种子纹理,使其比对照(自来水)颜色更深。途径扫描电镜分析显示,与对照相比,5 min-GAPAW处理的种子没有变化,但在15 min-GAPAW处理时观察到显著变化。与其他处理(0和5分钟)相比,15 min gapaw的发芽率为100%。15 min-GAPAW处理的茎长、叶宽、领径、叶绿素含量和吸水量均高于其他处理。该应用可以突出GAPAW在作物生产中的萌发特性。
