Title
Mechanisms of bicarbonate induced iron-deficiency chlorosis of peanut on calcareous soils
Ren Li; Zuo Yuan; Zhang Fu 2005
Other claims from this paper (12)
- Intervention effect Bicarbonate and iron treatments significantly influenced peanut iron nutrition.
- Observation Untreated peanut had no chlorotic symptoms.
- Intervention effect Adding bicarbonate to soil initially caused chlorosis.
- Observation Chlorosis disappeared after roots reached the iron-supplied nutrient solution.
- Observation In treatment III, young peanut leaves became chlorotic after roots reached nutrient solution.
- Association Chlorosis and regreening coincided with changes in active and total iron concentration.
- Observation Root iron concentration did not decrease in chlorotic plants.
- Observation Root apoplastic iron concentration increased in chlorotic plants.
- Intervention effect Bicarbonate added to soil or nutrient solution decreased Fe(III) reductase activity in roots from the solution chamber.
- Intervention effect Bicarbonate did not decrease Fe(III) reductase activity in roots from the soil chamber.
- Association Treatment III chlorosis increased rhizosphere bicarbonate concentration.
- Mechanism Bicarbonate was interpreted to inhibit iron translocation from roots to shoots.
