EFFECTS OF DIFFERENT SALT CONCENTRATIONS ON THE GERMINATION AND SEEDLING DEVELOPMENT OF RYEGRASS (Lolium perenne L.)

Abstract

This research was conducted to investigate the effects of five different salt concentrations (0, 5, 10,15 ve 20 dS m-1 NaCl) on the germination and seedling development of ryegrass (Lolium perenne L.)at the Field Crops Department Laboratory in Agricultural Faculty of Isparta University of AppliedScience in 2018. This research was set up in randomized block design with four replication. Thegermination rate, shoot and root lengths and fresh weights and salt tolerance index were determinedin this research. According to the results of the research, salt concentrations had significant effect onall properties. Increased salt concentrations caused decreased the germination rate, shoot and rootlengths and fresh weights, shoot/root ratio, and salt tolerance index. The lowest values were obtainedfrom 20 dS m-1 NaCl.
