Effect of Silicium on Reducing Salt (Nacl) Stress in Beans (Phaseolus Vulgaris L.)

Abstract

In this study, the effects of silicon applications (control, 50, 100 and 200 ppm) on some physiological and biochemical parameters in the plant (Phaseolus vulgaris L.) grown under different salt (NaCl) dose applications (control, 50, 100 and 150 mM) were determined. Parameters such as root and stem length, root and stem age weight, root and stem dry weight, leaf area index, SPAD index, ion leakage in leaf tissues, membrane resistance index in leaf tissues and malondialdehyde (MDA) level were investigated. The results indicated that the effect of salt stress on all parameters examined was found statistically significant. It was determined that salt stress conditions caused ion leakage in leaf tissues and decreased in all parameters except MDA. The effect of silicon applications on all other parameters except for relative water content in leaf tissues, ion leakage in leaf tissues and membrane resistance index in leaf tissues was found statistically significant (p <0.05 and p <0.01).
