On the salt tolerance of ryegrasses and fescues

Abstract

The experiments were carried out in 1966 to know the salt tolerance of lawn grasses. Perennial ryegrass, Italian ryegrass, and Creeping red fescue were grown in sand cultures at various concentrations of NaCl. Hoagland's solution was used as the basic solution (control), and the concentrations of CI to it were 1000, 5000, 10000, and 15000ppm, respectively. The results obtained are summarized as follows.
1. The growth of ryegrasses and fescues were almost normal at Cl 1000ppm similar to control. In the 5000Ppm application, it became worse and most plants died. In concentration of Cl above 10000ppm, the grasses are inpossible to live.
2. With increasing concentration of Cl, plants were dwarfed and the number of sterns, leaves and roots reduced.
3. As results of this experiments, perennial ryegrass, Italian ryegrass, and Creeping red fescue were comparatively strong to salt solution. Among the grasses, according to salt tolerance, they were arranged as follows:
Perennial ryegrass>Italian ryegrass>Creeping red fescue.
