Calcium and Strontium Relationship in Various Commercially Important Plants¹

The rate of uptake and the degree of translocation of strontium was investigated, as well as the amounts taken up and the effects on the growth of sorghum, cotton, and bean plants when high levels of strontium are incorporated into the culture medium. Strontium was shown to be taken up readily by the plants and also to be very mobile in actively growing plant tissue. Species differed in growth response to Sr with the greatest retarding (toxicity) effect occurring with bean plants. Species showing the largest percent of Ca in plant tissue in a Sr-free culture showed the largest concentration of Sr in a Ca-free culture. Generally, the Sr content of plant tops was higher than roots at all Ca/Sr ratios in the culture solution.

Key Words: Sorghum • Cotton • Sr uptake • Ca/Sr ratio
