Sažetak
This paper deals with the influence of Mg, N and content of chlorophylls on pfotosynthetic productivity of two new genotypes of winter wheat, Lara and Perla, at two locatities, Donji Miholjac and Kutjevo, during the vegetation periods 1997/1998 and 1998/1999. The applied parameters were determined by standard methods. The results showed effects of Mg concentration on all examined parameaers with the exception of chlorophyll b content. The highest correlation coefficient was with N concentration, significant correlation between the leaf area and N concentrations and between the leaf area and chlorophyll a. Statistical analysis showed very significant relationship between the content of organic matter and exmined parameters with a large number of significant correlations. The most important correlation was found between the content of organic matter and N concentration, and between chlorophyll a, chlorophyll b, carotinoids and the content of organic matter. The link between N, Mg and the other examined parameters was firm and significant as well as under strong influence of eternal factors.
