1. As a part of the series on the salt tolerance of lawn grasses, the experiments were made to investigate the salt tolerance of bentgrasses (highland bentgrass and seaside betgrass) and bluegrass (Kentucky bluegrass and annual bluegrass)<BR>2. The grasses were grown in sand culture at various concentrations of NaCl. The growth of bentgrasses become worse at Cl 1, 000ppm. and a few plants died. In the 5, 000 ppm application, almost all plants died. The growth of bluegrasses was somewhat checked at Cl 1, 000ppm, and became worse at Cl 5, 000-10, 000 PPm. In the 5, 000-10, 000ppm application, most plants died, and the rest seemed to live hardly.<BR>3. With increasing concentration of Cl, the grasses were dwarfed, and the number of stems, leaves, and roots reduced.<BR>4. As a rule, bluegrasses were conparatively better on the salt tolerance than bentgrasses, while they were considerably weak to salt solution in comparison with ryegrasses and fescues. Among the grasses, according to salt tolerance, they were arranged as follows:<BR>Kentucky bluegrass > annual bluegrass<BR>> seaside bentgrass > highland bentgrass.
