S ummary The efficiency of the mycorrhizal fungi Cenococcum graniforme and Suillus luteus on young seedlings of Pinus radiata for phosphorus uptake from different sources was investigated using 32 P. There was a stimulatory effect of mycorrhizas with Suillus luteus on uptake of phosphorus. Cenococcum graniforme had a stimulatory effect on incorporation of 32 P only when most of the phosphorus was in organic form. In the other conditions this symbiont had an inhibitory effect. There was a greater accumulation of phosphate in the roots than in the green parts of the seedlings.
