Abstract :Salinity causes significant crop loss every year. Excessive salinity has different effects on plant nutrition and metabolism. In this experiment, violet plants (Saintpaulia ionantha L.) were used and the experiment was set up in 1.5 kg pots. Plants were grown under laboratory conditions. Water containing different salt concentrations prepared from sodium chloride (S1=control=0 dS m-1, S2=2 dS m-1, S3= 4 dS m-1, S4=6 dS m-1, S5=8 dS m-1 and S6=10 dS m-1) were used. After 2 months, in order to investigate the plant development, leaf area, root fresh-dry weights and leaf fresh-dry weights were measured. In addition, P, K, Ca, Na, Fe, Cu, Zn and Mn contents in the roots and leaves of violet plants were also determined. Considering the obtained data, salt doses did not have a significant effect on leaf area, leaf fresh-dry weights and P, K and Ca values in roots. It was determined that fresh-dry weights of Saintpaulia ionantha L. plant roots and Na, Fe, Cu, Zn and Mn contents in roots changed significantly (P<0.01) with salt applications. It was found that salt applications decreased root fresh-dry weights. Na contents in plant roots were highest in 4 and 10 dS m-1 salt applications. Mn, Zn and Fe contents in roots increased up to 8 dS m-1 application, and Cu contents up to 10 dS m-1 application. When the nutrient elements in the leaves were examined, it was determined that Ca and Na contents increased significantly (P<0.01) and K contents increased but were not significant. It was found that micro elements (Mn, Zn, Cu and Fe) in plant leaves increased significantly (P<0.01) with salt applications. The microelements increases were determined up to 10 dS m-1 application in Zn, up to 8 dS m-1 application in Mn and Fe, and up to 4 dS m-1 application in Cu contents. According to the results obtained, it was determined that the violet plant is tolerant to salt applications up to a certain level.
