摘要
The effects of different concentrations of various macroelements on growth and endogenous GAs levels in root, stem, and leaf tissue of maize plants (Zea mays L.) were studied. Plants were cultivated in sand and supplied twice a week with a nutrient solution containing optimum, excessive, or deficient concentrations of nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, and iron. Plants were harvested from three different periods: vegetation (4–5 leaves), flowering, and fruiting. The levels of gibberellic acid-like substances (GA3 equivalents ng g-1 FW) were determined by using high-performance liquid chromatography (HPLC).
