Abstract: The contents of 5 metal ions in root, shoot and leaf of three warm-season turfgrasses in soil salt stress were studied. The results showed that with salt stress aggrevating, content of Na+ increased in root, leaf and shoot, and the proportion of Na+ in shoot and leaf increased remarkably. Under the same concentration of salt stress, the content of Na+ of Centipedegrass was higher than those of Zoysiagrass and Manilagrass. The difference of Na+concentration between Zoysiagrass and Manilagrass was unremarkable with low concentration of salt treatment, but under 0.8G salt treatment, the content of Na+ in Zoysiagrass was higher than that in Manilagrass. Keeping high K+ concentration could be one way to get high salt tolerance of Zoysiagrass and Manilagrass, while Centipedegrass declined in its salt tolerance with the K+ concentration decreased under salt stress, and its salt tolerance was poor. Fe3+ concentration and RS (K+.Na+) changed trend could be used to estimate the turfgrass salt tolerance.
