  Little is known about the uptaken nutrient distribution and their relationship with the tendency of dry matter accumulation within the spike of wheat, whereas such findings are important for increasing grain yield without quality loss. In this research, we aimed to identfy the distribution of macro elements like calsium (Ca) and potassium (K) and micro elements like Manganese (Mn) and zinc (Zn) in different parts of spike (distal, middle and proximal) and spikelet (large and small seeds) during the duration of grain filling in two different varieties of wheat named: Mahdavi and  Falat. The results showed that the highest weight was obtained for the grains in the central part of spike as compared to the proximal and distal parts. Mn and Zn concentrations were decreased during the grain filling in three parts of the spike. There was a positive correlation between grain weight and concentration of macro – micro elemnts at various parts of spike. This correlation was stronger in the central part as compared other parts of spike (top and base). There was a considerable decrease of Mn and Zn in the seeds produced at the top of spike. However, a low concentration of elements in relation to the position of seeds on the spiklet was more remarkable than of that in the spike. There was no significant differences between two varieteis examined in this study in respect of nutrient distribution along the rachis and in rachilla. Manuscript profile
