Abstract

This study was conducted with 4 bread wheat genotypes to determine the macronutrient content in different plant organs during the grain filling period. Macronutrient contents such as nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) were determined in lower stems, peduncles, lower leaves, flag leaves, rachises, florets, and grains. High genotype effects were found for all macronutrients and plant organs. N, P, K, and Mg decreased during grain filling in all plant parts except the grain. The rate of decrease varied depending on plant organs and nutrients. Grain nutrient concentration, except nitrogen content, increased up to physiological maturity. In contrast to the other nutrients, Ca content increased or remained stable depending on the plant organs. The macronutrient remobilization order from plant organs to grain was Mg < P < N < K Keywords: Bread wheat, grain growth, nutrients, translocation, plant parts
