Abstract
Over 300 samples of plants, representing 77 spp. that are native to New Jersey and 24 vars. of cultivated plants, were analyzed for Na and K. The Na content of wild plants varied between 0 and 2.04% and that of the cultivated plants between 0 and 3%. The Na content of most plants was much lower than their content of K. The Na content of certain spp. of Typha, Sieglingia and Iva was higher than the content of K. Only 4 of the 15 grasses analyzed contained > 0.1% Na. The legumes, especially Ladino and red clovers, tended to contain higher percentages of Na than the ordinary grasses. Of the common weeds, certain spp. of burdock, mustard, plantain and yarrow had the highest Na content. The common vegetables, cabbage, carrots, radishes, spinach and beets, contained high percentages of Na. On basis of the analytical data the plants were divided into 4 types: Plants that did not accumulate Na; plants that accumulated Na if it was present in abundance; plants that accumulate Na whether it was abundant or not; and plants, native to salt-marsh areas, that are normally high in Na.
