Influence of toxic concentrations of micro-nutrient elements in the nutrient medium on vitamin content of turnips and tomatoes

· Bot. Gaz. (Chicago); (United States)
As the iron concentration in the nutrient medium was increased to 147 ppm, no significant effects on the growth of either turnips or tomatoes were evident. As the concentration of copper, manganese, boron, zinc, or molybdenum was increased in the nutrient medium, the growth of both turnips and tomatoes was significantly retarded. Toxicity symptoms developed, and as the supply of any of the elements used was increased, a greater concentration of that element was found in the vegetative plant parts. As the boron supply to turnip plants was increased, a 60% increase in both niacin and thiamine concentration in leaves occurred. Ascorbic acid values, however, were 20% less. A 35% increase in both niacin and riboflavin values was associated with increased manganese supply. In this instance, ascorbic acid values were 25% less. In tomatoes a 60% increase in ascorbic acid content of the fruit was associated with relatively high copper concentrations in the nutrient solution. 34 references, 8 tables.
