Summary
1. Seedlings ofHevea brasiliensis were grown in sand culture under conditions of varied mineral status; the laminae were analysed for molybdenum by a bioassay and by a chemical method.
2. Both the bioassay and chemical methods indicated that sulphur-deficient laminae possessed a much higher concentration of molybdenum than those of normal plants.
3. The interpretation of the effects of some of the treatments on the accumulation of molybdenum in laminae depended on the method of molybdenum estimation; it was suggested that some laminae, even after wet digestion, contained constituents which interfered with the bioassay method of estimation.
