Salicylic acid, ascorbic acid and wood vinegar effects on fenugreek (Trigonella foenum-graecum L.) plant germination at various salt concentrations

Abstract

The aim of this study was to ascertain the impact of applying ascorbic acid (AsA), salicylic acid (SA) and wood vinegar at varying concentrations of salt (NaCl) on the germination and other physiological parameters of fenugreek (Trigonella foenum-graecum L.) seeds. Four different NaCl concentrations (0, 50, 100, and 150 mM), four separate SA and AsA applications (0, 50, 100, and 150 mM) and wood vinegar (0.05 %, 0.10 %, 0.15 %) were used in the study for each application. The study looked at the following criteria: germination rate (%), germination duration (day), root length (cm), and stem length (cm). This investigation showed that higher salt concentrations had a negative effect on germination. Positive effects on germination and other parameters were also found with treatments of 50 mM and 100 mM AsA and SA. It has been found that the optimal administration of AsA and SA can positively impact fenugreek plant germination in saline environments. In addition, 0.10 % dose of wood vinegar had a more positive effect than other application doses.
