The accumulation of radioactive strontium by plants is of considerable interest because of fallout from weapons testing. Although this problem has received considerable attention little is known concerning phosphorus effects on strontium accumulation. For background information on a different subject several exploratory studies have been made in this laboratory of possible phosphorus effects on accumulation of Sr/sup 85/. Results indicate that without added bicarbonate, increasing the phosphorus increased the content of Sr/sup 85/ in roots but had little effect on that in the tops. With a 10/sup -2/M bicarbonate level, increasing the phosphorus resulted in a progressive decrease of Sr/sup 85/ in both roots and tops. In the absence of phosphorus from the nutrient solution, the content of Sr/sup 85/ in the roots increased markedly with the concentration of bicarbonate. The concentration of Sr/sup 85/ in the tops increased with bicarbonate concentration up to a level of 0.005M and then decreased. At a 10/sup -3/M level of phosphorus, increasing the bicarbonate also resulted in increased amounts of Sr/sup 85/ in roots but in slightly decreased amounts in tops which may not be significant. At the 10/sup -2/M level of phosphorus, increasing the bicarbonate definitely resulted in decreased amounts of Sr/sup 85/ in both tops and roots.
