The Effect on Morpho-Physiological and Biochemical Characteristics of Cauliflower and Cabbage Harvested at Different Times Under Flooding Stress Conditions
Climate change-induced flooding has a profound impact on plant growth and development, posing a significant abiotic stressor that significantly affects the yield and quality of cabbage and cauliflower. In many regions, cabbage and cauliflower is severely affected by flooding stress during the cultivation period. This study aimed to assess and compare the effects of flooding stress on the morpho-physiological and biochemical properties of cabbage and cauliflower at different harvest times. In this context, cabbage and cauliflower seedlings were exposed to excess water, and essential parameters, such as photosynthesis, antioxidant enzymes, chlorophyll fluorescence, and certain agronomic features. As a result of flooding stress, significant decreases occurred in agronomic features were measured. The results showed significant decreases in agronomic parameters, including aboveground and underground fresh and dry weights, as well as leaf area. It was observed that the damage rate of plants increased as the exposure time to flooding stress increased. In our experiment, proline, an essential amino acid, significantly increased under flooding stress at different harvest times. Furthermore, the activity of catalase and ascorbate peroxidases, which are reactive oxygen species (ROS), also significantly increased in our investigation. In our experiment, we observed significant increases in proline, an essential amino acid, under flooding stress at different harvest times. Additionally, the activity of catalase and ascorbate peroxidases, which are reactive oxygen derivatives (ROS), also significantly increased. Furthermore, decreases were noted in stomatal conductivity, photosynthetic efficiency, leaf temperature (°C), and chlorophyll fluorescence levels. The application of flooding stress at various harvest times had a negative impact on the growth and development of cabbage and cauliflower plants, leading to significant alterations in their physiological and biochemical properties.
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.
