Abstract

The study aimed to investigate the impact of Glycine Betaine (GB), Salicylic Acid (SA), and Ascorbic Acid (AsA) on the yield and quality of cotton plants during the 2021 and 2022 growing seasons at Harran University’s experimental fields in Şanlıurfa, Turkey. The research employed a split-plot design with three replications. Main plots were assigned for chemical applications (GB, SA, and AsA), while subplots were designated for different irrigation levels (IW1: Kp;1.00, IW2: Kp;0.75, and IW3: Kp;0.50). The study revealed that crop evapotranspiration varied between 400 to 728 mm in 2021 and 489 to 841 mm in 2022. The application of GB, SA, and AsA increased irrigation water productivity, especially under drought stress (DS) conditions, indicating the potential to enhance water productivity in cotton plants. DS resulted in significant reductions in various parameters such as plant height, shoot fresh weight, shoot dry weight, SPAD values, boll number, boll weight, cotton yield, ginning outturn, and 100-seed weight. However, the application of GB, SA, and AsA led to statistically significant (P ≤ 0.05) increases in these parameters under DS. Contrary to this, the application of GB, SA, and AsA did not have a statistically significant effect on ginning outturn and 100-seed weight under DS. GB, SA, and AsA applications demonstrated effectiveness in enhancing drought tolerance in cotton. These applications can help reduce yield losses in cotton production under drought conditions. Importantly, by conserving water and preventing yield losses, they offer valuable support to the textile industry.

为增强棉花对干旱情景的适应性和提高用水效率而研究合适的溶酶体
该研究旨在调查甘氨酸甜菜碱(GB)、水杨酸(SA)和抗坏血酸(AsA)对土耳其桑尼乌尔法哈兰大学实验田 2021 年和 2022 年生长季棉花植株产量和质量的影响。研究采用了三次重复的小区设计。主小区用于施用化学药剂(GB、SA 和 AsA),子小区用于不同的灌溉水平(IW1: Kp;1.00,IW2: Kp;0.75,IW3: Kp;0.50)。研究表明,2021 年作物蒸散量在 400 至 728 毫米之间,2022 年在 489 至 841 毫米之间。施用 GB、SA 和 AsA 提高了灌溉水生产力,尤其是在干旱胁迫(DS)条件下,这表明施用 GB、SA 和 AsA 有可能提高棉花植株的水分生产力。干旱胁迫导致植株高度、嫩枝鲜重、嫩枝干重、SPAD 值、棉铃数、棉铃重、棉花产量、轧棉产量和 100 粒籽重等各项参数显著降低。然而,在 DS 条件下,施用 GB、SA 和 AsA 会导致这些参数显著增加(P ≤ 0.05)。与此相反,在 DS 条件下,施用 GB、SA 和 AsA 对轧花出穗率和百粒重没有显著的统计学影响。施用 GB、SA 和 AsA 能有效提高棉花的抗旱性。这些应用有助于减少干旱条件下棉花生产的产量损失。重要的是,通过节约用水和防止产量损失,它们为纺织业提供了宝贵的支持。

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.
