Other claims from this paper (11)
- Intervention effect Wheat grain yield decreased significantly with increasing duration of waterlogging in sodic soils.
- Intervention effect In Indian alkali soils (pH 8.5 and 9.2) soil redox potential decreased sharply after waterlogging, reaching 150 and 210 mV at 10 days.
- Intervention effect In two Australian soils redox potential was similarly reduced, to about 200 mV at 10 days after waterlogging.
- Intervention effect In Australian soils without added glucose, redox potential was further reduced to 100 mV after 40 days of waterlogging.
- Intervention effect In Australian soils with added glucose, redox potential was further reduced to –50 mV after 40 days of waterlogging.
- Observation Indian soils tended to be 2–10 times higher in DTPA-Mn than the Australian soils.
- Observation Australian soils were up to 10 times higher in DTPA-Fe than the Indian soils.
- Observation The increases in soil Mn and Fe were up to 10 and 60 times higher, respectively, than reported critical concentrations for wheat.
- Intervention effect After drainage and re-aeration of Indian soils, DTPA-Fe and -Mn in soil solutions decreased.
- Mechanism The authors interpret the results as supporting that waterlogging tolerance is a product of tolerance to anoxia and microelement toxicities, both key factors limiting plant growth.
- Mechanism The authors suggest these factors may also contribute to large differences in screening wheat varieties for waterlogging tolerance in different soils.
