Impact of salicylic acid on Echinacea (Echinacea purpurea L.) plant germination at different salt levels

The purpose of this study was to determine how applying salicylic acid (SA) at different salt (NaCl) concentrations affected the germination and other physiological characteristics of Echinacea (Echinacea purpurea L.) seeds. Four distinct SA applications (0, 50, 100, and 150 mM) and four distinct NaCl concentrations (0, 50, 100, and 150 mM) were employed in the study for each application. The following factors were examined in the study: root length (cm), stem length (cm), germination period (day), and germination rate (%).

Higher salt concentrations had a detrimental influence on germination, according to this experiment. Moreover, 50 mM and 100 mM SA treatments showed favorable impacts on germination and other metrics. The germination of fenugreek plants in saline settings has been observed to be positively impacted by the optimum delivery of SA.
