Effect of Saline Water on Physiologycal Traits of Fenugreek (Trigonella foenum- graecum L.) in Hydroponic Culture

In order to investigate the effect of different levels of salinity on physiological traits in fenugreek, an experiment was conducted at the greenhouse of Ferdowsi University of Mashhad, using Completely Randomized Design with 10 replications. Treatments included irrigation water salinities of 0, 60, 120, and180 mM sodium chloride. The results showed that different levels of salinity had negative effects on physiological characteristics at 60, 120, and 180 mM sodium chloride and reduced shoot biomass by 37%, 50%, and 53% ; fruit biomass by 8%, 34%, and 45%; and 16% of chlorophyll index and 0, 4%, and 27% chlorophyll a/b, respectively, compared with 0 mM sodium chloride.
