SALT TOXICITY OF CONIFERS

In an attempt to determine how salt affects soft woods, a cooperative project was conducted to compare methods of salt application in relation to severity of toxicity symptoms in conifers of differential salt tolerance. The project was also designed to measure that amount of sodium and chloride in the tissue of two coniferous species when treated with salt solutions of varying concentrations applied either as a foliar spray or a soil drench. The morphological and anatomical effects of salt applications on two coniferous species was examined, and the sodium content of coniferous tissues was quantitatively measured using two methods for applying the Na(22) Cl solution. The study also attempted to determine the impact of one seasons salting on soil and vegetation along a newly opened section of an Interstate highway. A review of more than 1,000 studies on the effects of salt injury to plants is summarized, and details are given of the materials and methods employed in the three studies. The observations and results are discussed and based on the study are presented.
