Mechanisms of bicarbonate induced iron-deficiency chlorosis of peanut on calcareous soils
石灰性土壤上HCO3-诱导花生缺铁失绿机制

Dicotyledonous plants are prone to iron-deficiency chlorosis when grown on calcareous soils. This nutritional disorder problem occurs widely and can be a limiting factor for crop yield and quality. The main reasons for the disorder are high pH and high bicarbonate (HCO~-_3 ) concentration in soil solution. It has been shown that HCO~-_3 induces chlorosis by suppressing iron uptake and/or translocation in plants, although the relationship between HCO~-_3 accumulation, iron-deficiency chlorosis and rhizospher...
