The critical concentration of manganese in field-grown wheat locations
Aims

To determine critical concentration of manganese in wheat shoots for growth.

Key messages
  • Critical concentration of manganese in wheat tissues for optimal growth was determined.
  • In the youngest emerged blade the critical concentration was 11 µg per gram.
  • The critical concentrations for whole tops were 12 µg per gram.
  • The older blades were less sensitive determinants of the growth response and are not recommended for analysis.
  • Diagnosis using whole tops was less sensitive than with youngest expanded blade but may give an integrated picture of man manganese deficiency where availability varies with time.
  • The critical level of manganese was the same for 2 genotypes differing in their ability to tolerate manganese deficiency.
