Salt tolerance & protoplasmic salt hardiness of various woody & herbaceous ornamental plants

Abstract

Salt-hardiness was measured by the plasmolytic and tetrazolium methods. Salt-tolerant species included Salix alba var. vitellina, Robinia pseudoacacia, Gleditsia triacanthos var. inermis, Elaeagnus angustifolia, and Tamarix gallica. Among the somewhat salt-tolerant species were Juniperus virginiana, Pinus ponderosa, and Fraxinus pennsylvanica var. lanceolata. Among the non-tolerant species were Picea pungens, Juglans nigra, Tilia cordata and Pseudotsuga taxifolia.
