Influence de l'apport de strontium stable au sol sur la contamination par 90Sr de végétaux cultivés ray-grass et trèfle violet

The aim of experiments performed, in field conditions, from 1960 to 1962, was to study the behaviour of rye-grass and clover growing in soil in which various levels of stable strontium were added.
The statistical analysis of results shows that the different treatments have no significant effect, at the P 0.05 level, on the ⁹⁰Sr content of the foliage and the roots. But the differences in ⁹⁰Sr content of these two species are significant at the P 0.01 level : content of rye-grass is lower than that of clover.
