“…These effects were significantly better over those induced by the corresponding concentrations of Fe-EDTA, possibly due to known higher stability constant of Fe-EDDHA as well as its better mobility in plants (13,9,10). While in the control (iron-untreated) plants chlorophyll destruction (quite simultaneously a decline in the IAA content) is more rapid at post-flowering stage, leading to an early senescence, reduced photosynthetic duration and low yield, the iron-treated plants exhibited a delayed senescence of leaves coupled with a significantly enhanced photosynthetic duration and yield (total dry matter and seed yield, as evident from tables 2 and 3).…”

A bioassay system using mutant strains of Escherichia coli K12 was developed which can detect four different types of siderophores. These types are: ferrichrome and its analogs; enterochelin; coprogen, rhodotorulic acid, and ferrioxamines A, B, D 1 , and G; and a group of unidentified chelators which forms a part of E. coli's high affinity iron transport system. The amount of the four siderophore types in concentrated water extracts of bulk and rhizosphere soil from a field sample was estimated using this bioassay.

“…In addition, Amaranthus spp. (commonly pigweed) residues mixed with exogenous iron sulphate (FeSO 4 ) were more effective than Fe-EDDHA in reducing Fe chlorosis and increasing plant dry matter and grain yields in sorghum plants grown on severely Fe-deficient soil (Matocha and Pennington 1982;Matocha 1984;Mostaghimi and Matocha 1988).…”

The aim of this study was to evaluate the effectiveness of soil-applied aqueous extract of Amaranthus retroflexus L. in preventing lime-induced iron (Fe) chlorosis of pear trees (Pyrus communis L.). Tree growth, nutritional status, yield and fruit quality were also assessed. The aqueous extract was obtained by soaking dried and ground canopy (epigeal part) of spontaneous A. retroflexus plants in tap water. A. retroflexus extract was chosen because of its ability to solubilize Fe from calcareous soil, which was found to be 100-fold higher than deionized water alone. Two experiments were carried out (controlled environment and commercial field conditions) where soil-applied aqueous extract of A. retroflexus alone or mixed with iron sulfate (FeSO 4 ) was compared with synthetic Fe-chelate and an untreated control. Soil-applied aqueous extract of A. retroflexus increased shoot length, leaf SPAD and total plant biomass in controlled environment. In the commercial orchard control trees showed severe leaf Fe-chlorosis symptoms effectively prevented by Fe-chelate. The supply of A. retroflexus aqueous extract improved Fe nutrition of trees, particularly when enriched with FeSO 4 . Fe-chelate increased tree yield but decreased fruit weight, leaf potassium (K) and manganese (Mn) concentration. At harvest, all strategies raised fruit soluble solid concentration compared to the untreated control. Results showed that soil-applied A. retroflexus aqueous extract improved Fe nutritional status of pear trees, probably because of the natural Fe chelating capacity of the compounds released by its tissues.
