Palms are becoming popular landscape plants in the upper desert region of the Southwest where water used for irrigation has elevated salinity. An experiment was conducted in a greenhouse to evaluate leaf damage and growth response of nine cold-resistant palm species to salinity. One-year-old potted seedlings were transplanted to 10-liter containers filled with loamy sand and irrigated with saline solutions containing 800, 2000, 5000, and 7500 mg/liter of predominantly NaCl salts. The corresponding electrical conductivity was 1.2, 4.4, 9.4, and 13.7 dS/m, respectively. Seedlings were irrigated at a leaching fraction of 30 to 35% for six months, and leaf growth, leaf injury, and leaf mineral contents measured. Under this irrigation regime, salinity of irrigation solutions approximately equals salinity of the soil saturation extract. Leaf growth and leaf injury were highly species-dependent. A significant growth reduction and leaf injury of Sabal palmetto, Butia capitata, and Trachycarpus fortunei appeared when irrigated with the 4.4 dS/m solution, those of Trithrinax brasiliensis, Brahea armata, and Sabal minor when grown with the 9.4 dS/m solution, and Washingtonia filifera, Washingtonia robusta and Phoenix canariensis, using the 13.7 dS/m solution. Injured leaves of poorly-tolerant species contained unusually large amounts of Na (10 to 70 g/kg) when irrigated with the 9.4 dS/m solution. W. filifera, W. robusta, and P. canariensis seem to be ideal species for saline areas.
