Abstract
Salinity is a major abiotic stress that can affect plant growth and development adversely. However, there is bare knowledge about its role in the quality of the seeds obtained from the plants that are grown under salinity. The present study aimed to explore the effect of salinity stress (control (0.7), 3.5, and 7 dS m−1) on the seed germination parameters, 1000-seed weight, plant growth, and proline content of pepper (Capsicum annuum L.) genotypes (Maras, Carliston, and Dolmalik) in the greenhouse in 2018. The results showed that salinity stress significantly affected pepper genotypes, but their response to salinity stress was different. In this respect, the Maras genotype showed the highest proline content, leaf area, and plant biomass and showed tolerance to salinity stress relative to the other genotypes. Concerning seed germination rates, Carliston and Dolmalik experienced severe reductions of 60 and 68%, respectively, under 7 dS m−1 salinity level compared to the control, while the Maras genotype showed a mild drop of 27%. At a higher salinity level of 7 dS m−1, there was a negative impact on 1000-seed weight, resulting in reductions of 20.73%, 36.12%, and 34.39% in Maras, Carliston, and Dolmalik, respectively. Importantly, the study findings underscored that salinity stress had a less severe adverse effect on the seed germination parameters and 1000-seed weight of the Maras genotype compared to the other genotypes, signifying its heightened tolerance to salinity. Furthermore, the present findings revealed that a reduction in both plant growth and biomass during the vegetative growth phase exerts adverse effects on seed weight and seed germination parameters. Moreover, the research identified the Maras as a salinity-tolerant genotype, which makes it a potential candidate for breeding programs.
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.
