Phosphorus levels of young mature (11- to 14-day-old) Pinto beans (Phaseolus vulgaris Pinto) were examined after ozonation (0.20-0.25 ppm/1.5-3 hr). The plants had been grown in sand culture and supplied with a standard nutrient solution having a phosphorus concentration of 15.5 ppm. Phosphorus determinations were carried out on three fractions from each plant: stem, primary leaves, buds, and trifoliate leaves. Determinations included both standard phosphorus analyses (J. Official Agr. Chemists Assoc.) and radiotracer techniques using liquid scintillation counting. Samples for phosphorus determinations were harvested at 0, 6, 24, and 48 hr after ozonation. A significant increase of phosphorus levels in the primary leaves occurred in ozonated bean plants. This increase was sometimes evident immediately after ozonation, but always within 48 hr after ozonation when characteristic ozone-induced bleaching and stipple had developed on primary leaves. Experiments conducted on plants grown in nutrient solution culture and soil showed no significant increases in phosphorus levels of ozonated plants.
