Abstract/Contents:"Seawater of different salinity levels (0, 24, 48, and 72 dSm-1) were applied to 16 turfgrass species that grown in plastic pots filled with a mixture of sand and peat (9:1v/v). Chlorophyll concentration decreased significantly with increasing salinity. P. Vaginatum and Z. Japonica maintained greater amount of total chlorophyll than the others turfgrass species under salt stress. Increasing salinity also decreased K, Ca, Mg content and K/Na ratio but increased Na content in the shoot tissue. The K, Ca, Mg content reduction was the lowest in the species of Paspalum vaginatum, Zoysia japonica and Zoysia matrella while the highest K reduction was in the species of Digitaria didactyla at all salinity levels followed by Axonopus affinis, Cynodon dactylon 'tifdwarf', Cynodon dactylon 'greenlesspark' and Axonopus compressus (pearl blue). Other species were the intermediate. The overall, shoot K/Na ratio was the highest in Paspalum vaginatum followed by Zoysia japonica, whilst the lowest K/Na ratio was in Axonopus compressus (pearl blue) followed by C. Dactylon 'greenless park'. The results revealed that K, Ca and Mg ions uptake and their distribution to shoot tissues under salinity stress may be relevant issues for salt (Na+) exclusion studies and for plant nutrition as well."
