Abstract
Maize inbreds (Mo-17, ZPL-501, OH-43, A-632-Ht, ZPL-500) of different genetic origin and almost coincident growing season were selected. Plants were grown in nutrient solution of different nutrition levels (1/8 and 1/2 strength of a full Reid-Jork solution, full nutrient solution 1, and 2 and 3 times as strong as a full nutrient solution) for 25 days. The effects of mineral nutrition on dry mass of root and aboveground part and ion concentrations were examined.
Dry matter accumulation into root and aboveground part depended upon inbred line and the nutrition variant employed. On the average, the highest dry mass was obtained with ZPL-500 and ZPL-501, whereas the lowest with A-632-Ht. Significant differences in element concentration relative to concentration of nutrient solution were found. The smallest differences were recorded for N (0–30%) while those for other elements were higher ranging from 40 to 70%. The differences in element concentration were more expressed in aboveground parts than in root. On the average, concentrations of elements increased as that of nutrient solution increased.
