摘要

摘要当前，世界农作物生产面临着诸多问题，其中危害最大的是灌溉缺水。节约灌溉用水是世界各国，特别是干旱地区各国的主要目标。田间试验旨在评估灌溉制度(灌溉需水量的100%、80%和60%、IR(分别为IR 100、IR 80和IR 60)、吸水物质(对照、水凝胶聚合物和沸石作为土壤添加剂)和叶面施用谷胱甘肽(GSH)[加或不加谷胱甘肽]对普通豆类植物生长性能的影响。结果表明，IR 80 ×沸石×谷胱甘肽组合获得的植物鲜重与IR 100 ×水凝胶聚合物或沸石×谷胱甘肽组合获得的植物鲜重无显著差异。水凝胶聚合物加谷胱甘肽对普通豆叶片氮、磷、钾积累有显著的促进作用。在IR 80和IR 60条件下，沸石加GSH分别使POX和CAT的积累减少了21.8%和15.5%，16.1%和7.6%。在IR 100、IR 80和IR 60条件下喷施GSH ×水凝胶聚合物，豆荚产量值较对照分别显著提高26.5%、25.23%和32.80%。无论是否添加GSH, IR 100与水凝胶聚合物的相互作用均显示出最高的N、P、蛋白质、纤维、碳水化合物百分比和TDS。简而言之，可以得出结论，持水改性剂(聚合物和沸石)以及低分子量抗氧化剂(谷胱甘肽)可以减轻干旱条件下活性氧产量升高的危害影响。实际上，建议普通豆种植者使用有效的土壤改良剂(水凝胶聚合物，0.24 t ha - 1或沸石，1.20 t ha - 1)处理土壤，并向普通豆植株喷洒谷甘肽，1.0 mM，以在缺水条件下维持作物的生产力和质量

Rhizospheric Addition of Hydrogel Polymer and Zeolite Plus Glutathione Mitigate the Hazard Effects of Water Deficiency On Common Bean Plants Through Enhancing the Defensive Antioxidants

Abstract Currently, the world is facing many troubles in crop production and the irrigation water deficit is the most harmful among them. Saving irrigation water is the main target for all countries of the world, especially in arid areas. Field trial was executed aiming to assess the influence of irrigation regimes (100, 80 and 60% of irrigation requirements, IR (IR 100 , IR 80 and IR 60 , respectively), water-absorbent substances (control, hydrogel polymer and zeolite as soil addition) and foliar application of glutathione (GSH) [with GSH or without] on the performance of common bean plants. Findings clarified that plant fresh weight obtained with the combination of IR 80 × zeolite × GSH had no significant differences with the superior combination of IR 100 × hydrogel polymer or zeolite × GSH. Hydrogel polymer plus GSH supply showed distinctive enhancements for N, P and K accumulation in common bean leaves. Application of zeolite plus GSH reduced the accumulation of POX and CAT by 21.8 and 15.5% under IR 80 and 16.1 and 7.6% under IR 60 , respectively. Spraying of GSH × hydrogel polymer under IR 100, IR 80 and IR 60 significantly increased the value of pods yield by 26.5%, 25.23% and 32.80, respectively, as compared to corresponding control treatment. the interaction of IR 100 and hydrogel polymer whether with or without GSH showed the highest significant values of N, P, protein, fiber, carbohydrates percentages and TDS. Briefly, it can be concluded that water holding amendments i.e., polymer and zeolite as well as low-molecular-weight antioxidants i.e., glutathione can mitigate the hazard impacts of elevated reactive oxygen species production under drought. Practically, common bean growers are advised to treat the soil with available soil amendment (hydrogel polymer, 0.24 t ha −1 or zeolite, 1.20 t ha −1 ) and spraying common bean plants by glutathione, 1.0 mM to sustain the crop productivity and quality under shortage water conditions

期刊介绍： Gesunde Pflanzen publiziert praxisbezogene Beiträge zum Pflanzenschutz in Landwirtschaft, Forstwirtschaft, Gartenbau und öffentlichem Grün und seinen Bezügen zum Umwelt- und Verbraucherschutz sowie zu Rechtsfragen. Das Themenspektrum reicht von der Bestimmung der Schadorganismen über Maßnahmen und Verfahren zur Minderung des Befallsrisikos bis hin zur Entwicklung und Anwendung nicht-chemischer und chemischer Bekämpfungsstrategien und -verfahren, aber auch zu Fragen der Auswirkungen des Pflanzenschutzes auf die Umwelt, die Sicherung der Ernährung sowie zu allgemeinen Fragen wie Nutzen und Risiken und zur Entwicklung neuer Technologien. Jedes Heft enthält Originalbeiträge renommierter Wissenschaftler, aktuelle Informationen von Verbänden sowie aus der Industrie, Pressemitteilungen und Personalia. Damit bietet die Zeitschrift vor allem Behörden und Anwendern im Agrarsektor und Verbraucherschutz fundierte Praxisunterstützung auf wissenschaftlichem Niveau.
