Özet

The effect of varied zinc (Zn) and iron (Fe) supply on the release of Zn and Fe mobilizing phytosiderophores from Toots was studied in Zn-efficient Aroona and Zn-inefficient Durati wheat genotypes (Triticum aestivum cv. Aroona; T. durum cv. Durati) grown under controlled environmental conditions in nutrient solution for 25 days. Phytosiderophore release was determined by the measurement of Zn and Fe mobilizing capacity of root exudates from a Zn-loaded resin and from freshly precipitated Fe-III hydroxide as well as identification by HPLC analysis.
