Short Communication


Tree seeds were germinated in a greenhouse soil mix amended with varying amounts of sodium chloride. The salt was added in amounts approximating certain roadside soil environments.Betula alleghaniensis, Catalpha bignonioides, Quercus coccinea andQ. cerris seed exhibited reduced germination percentage at the highest salt concentrations. Germination ofRobinia pseudoacacia seed was delayed as salt concentration was increased. Except for slight germination percentage reduction, seed ofAilanthus altissima, Pinus rigida andGleditsia triacanthos were uninfluenced by the salt treatments.
