Effects of Using Salicylic acid, Potassium chloride, and a Mixture of Salicylic acid and Potassium chloride Treatments on Salt-stressed Cucumis sativus CV. Malaysia timun2 Germination

In constructing a liquid enhancer, 300 mM NaCl was primed for 72 hours on sterile MTi2 seeds., after that, deionized water was used as a control, and SA alone (salicylic acid) (0.25, 0.5, 0.75, 1 mM) and only KCl (Potassium chloride) (10, 20, 30, 40, and 50 mM) were applied. As previously stated, germination parameters were computed. After that, the appropriate ratio of KCl to SA was combined, and its efficacy as a germination activator on the Salt-stressed MTi2 seeds was examined. The data analysis software used was SPSS Windows version 22. To find the significant difference between treatments, data are first subjected to a two-way ANOVA with p≤0.05 confidence level. For purpose of comparing means, DMRT is next applied at a p≤0.05. According to the results, the best concentrations for boosting the germination and early growth of MTi2 seedlings in comparison to the control treatment were found to be 20–30 mM KCl and 0.5–0.75 mM SA. Furthermore, MTi2 seedling germination and early growth were more than 1x higher when the best concentrations of KCl (20-30 mM) and SA (0.5-0.75 mM) were combined. Salicylic acid (SA) and low levels of KCl applied to salt-stressed MTi2 seeds can help reduce the negative effects of salinity stress and enhance the percentage, rate, vigour, length, and biomass of the seedlings that germinate. Conclusion, Salt-stressed MTi2 seeds can benefit from an enhancer that increases germKeywordsination at low concentrations of KCl and SA.
