TY - JOUR T1 - Tolerance Of Seven Woody Ornamentals to Soil-Applied Sodium Chloride JF - Arboriculture & Urban Forestry (AUF) JO - JOA SP - 162 LP - 165 DO - 10.48044/jauf.1978.038 VL - 4 IS - 7 AU - Michael A. Dirr Y1 - 1978/07/01 UR - http://auf.isa-arbor.com/content/4/7/162.abstract N2 - Two-year-old seedlings of seven woody ornamental species ranging in reported salt tolerance from good to poor were salinized with 250 ml of 0.25 N NaCI applied daily to the soil. Elaeagnus angustifolia and Rosa rugosa were not injured and contained the lowest leaf levels of Na and Cl. Elaeagnus umbellatus and Prunus tomentos showed the greatest injury while Acer platanoides, Prunus besseyl, and Rhus glabra were intermediate in tolerance. Leaf Na contents did not reflect the degree of injury among Elaeagnus umbellatus, Prunus tomentosa, Acer platanoides, Prunus besseyi, and Rhus glabra. However, leaf C| content in all injured species was greater than 2.5 percent and more accurately reflected the severity of injury although the most seriously injured species did not contain the greatest leaf Cl levels.
