PI-54619-S-1 (PI) and Hawkeye (HA) soybeans were grown using split-medium and split-root technjques to separate iron from the precipitating effects of bicarbonate and phosphorus. For comparative purposes, these were grown in complete solution cultures where iron, bicarbonate, and phosphorus were in direct contact with each other .
PI and HA soybeans did not develop chlorosis when grown using split-medium or split-root techniques with roots in 10 meq/1 NaHCO3 at comparatively low phosphorus concentration. In comparison PI soybeans developed chlorosis in complete solution
cultures when 2 meq/1 NaHCO3 was in solution. Cytochrome oxidase activity decreased with increasing bicarbonate concentration in complete solution cultures, but was dependent upon phosphorus concentration in the split-root experiments. Bicarbonate in solutjon cultures increased the soluble phosphorus concentration in solution. Development of iron chlorosis was more related to phosphorus concentration in solution or that absorbed by the plant than by bicarbonate concentration in solution. Cytochrome oxidase activity was affected by the phosphorus concentration. Bicarbonate does not appear to be a direct cause of iron chlorosis or directly inactivate cytochrome oxidase. An effect of phosphorus concentration on cytochrome oxidase activity was observed.
