E. Jurkevitch; Y. Chen; Y. Hadar Soil Science Society of America Journal 1988. doi:10.2136/sssaj1988.03615995005200040025x
Other claims from this paper (13)
- Observation Peanut plants were able to use the Fe from unpurified Fe-siderophore produced by Pseudomonas putida cultures.
- Observation The strain excreted yellow-green fluorescent siderophores when grown under Fe-deficient conditions.
- Observation The physico-chemical characteristics of the two main peaks were similar to those of the pseudobactin-pyoverdine class of siderophores.
- Intervention effect With 11 mg Fe kg-1 soil as Fe-siderophore, leaf chlorophyll was 75% of that of FeEDDHA-treated plants.
- Intervention effect Plants not fertilized with Fe had only 35% of the leaf chlorophyll of FeEDDHA-treated plants.
- Observation Nonferrated siderophores were ineffective in correcting Fe deficiency.
- Intervention effect Relative leaf chlorophyll with Fe-siderophore plus bacterial cells was similar to applications without bacterial cells.
- Intervention effect With 19 mg Fe kg-1 soil as Fe-siderophores, 100% remedy of the deficiency was achieved compared with 1.2 mg Fe kg-1 soil as FeEDDHA.
- Association The degree of chlorosis remedy did not depend on the frequency of application (two or four times a month).
- Observation Total bacterial and fluorescent pseudomonad root counts were significantly higher than in unfertilized and FeEDDHA treatments.
- Intervention effect Extractable Fe in soil was significantly higher with Fe-siderophore than with FeEDDHA.
- Intervention effect Iron applications of 22.5 and 45 mg Fe kg-1 soil as ferrioxamine B reached 70% of the chlorophyll of FeEDDHA-treated plants.
- Intervention effect Iron applications of 22.5 and 45 mg Fe kg-1 soil as ferrioxamine B reached 97% of the chlorophyll of FeEDDHA-treated plants.
