Tuz Stresinin (Potasyum Klorür) Aspir (Carthamus tinctorius L.) Çeşitlerinin Ekolojik ve Fizyolojik Özelliklerine Etkisi

Abstract

Salinity, which is a significant abiotic stress factor, is among the most important factors that limit product quality and yield. In this study investigated phenological and physiological changes that occurred in three different safflower varieties that were exposed to KCl stress at concentrations of 0, 50, 100 and 150 mM. It was found that, based on increasing salt concentrations, the most significant decrease was in all phenological parameters at the concentrations of 100 and 150 mM KCl. The SOD and CAT activities showed a significant increase at high salt concentrations in the Balcı and Dinçer varieties. The APX and GR activities showed a parallelism in all safflower varieties, and they showed a significant increase based on increased concentration at the applications of 100 and 150 mM KCl. Among the three safflower varieties, the most resistant variety to salt application was Dinçer, while the most sensitive one was Remzibey. The Balcı variety was closer to the Dinçer variety in terms of its tolerance against salt stress.

An assessment of the physicochemical characteristics and essential oil composition of Mentha longifolia (L.) Huds. exposed to different salt stress conditions

“…Previously, it was reported that treatment with 300 mM KCl in Chenopodium album reduced growth and significantly reduced carotenoid levels ( Yao et al., 2010 ). With rising concentrations of 50, 100, and 150 mM of KCl salt, the root and shoot growth of Carthamus tinctorius L. was also reduced ( Leblebİcİ et al., 2021 ). The growth of Triticum aestivum L. was reduced by more than 60 ppm of KCl ( Rasheed et al., 2020 ).…”
