Effect of salinity stress on nutrient uptake and chlorophyll content of tropical turfgrass species.
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 greate...
