Determination of The Reaction of Violet Plant (Saintpaulia ionantha L.) to Salinity

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
