The effect of ascorbic acid on the germination of catnip (Nepeta cataria) plants at different salt concentrations

This study aimed to determine how administering ascorbic acid (AsA) at different salt concentrations (NaCl) affected the germination and other physiological characteristics of catnip (Nepeta cataria) seeds. For each application, the study employed four distinct AsA applications (0, 50, 100, and 150 mM) and four distinct NaCl concentrations (0, 50, 100, and 150 mM). Germination rate (%), germination time (day), root length (cm), and stem length (cm) were the criteria examined in this study.

This study showed that germination was adversely affected by increased salt concentrations. Treatments with 50 mM and 100 mM AsA also showed positive effects on germination and other measures. It has been shown that catnip plant germination in saline conditions may be positively impacted by the ideal administration of AsA.
