Abstract
Salt tolerance of 8 ornamental tree species was determined in plots artificially salinized with NaCl and CaCl2. Tolerant species such as Italian stone pine (Pinus pinea L.) and evergreen pear (Pyrus kawakamii Hayata) were affected very little bv soil salinities of 9 dS/m (electrical conductivity of the saturation extract: ECe). Sweet gum (Liquidambar styraciflua L.), cherry plum (Prunus cerasifera J. F. Ehrh), Southern magnolia (Magnolia grandiflora L.), orchid tree (Bauhinia purpurea L.h crape myrtle (Lagerstroemia indica L.), and tulip tree (Liriodendron tulipifera L.) exhibited moderate to severe injury symptoms and a 33% or greater growth reduction. Injury symptoms became more severe with each growing season.Keywords
