Contribution of different mechanisms to zinc efficiency in bread wheat locations
Aims

To quantify the relative effects of different mechanisms of zinc efficiency in bread wheat.

Key messages
  • Soil and solution culture studies were conducted to examine the relative contribution of different mechanisms of zinc efficiency at the whole plant level in bread and durum wheat during early vegetative stage.
  • While there are a number of mechanisms of zinc efficiency, zinc uptake appears to be the most important mechanism • Seed zinc remobilisation and root to shoot translocation do not appear to be important to zinc efficiency.
  • Visual scores of zinc deficiency were significantly correlated with zinc efficiency, and they provide a useful criterion for an initial screen of zinc efficiency.
  • This study was based on vegetative growth and the conclusions need to be verified under field conditions.
  • The percentage deviation technique provided a straight forward means of comparing the relative effects of different components of zinc efficiency and the method could be extended to studies that use grain yield as the measure of zinc efficiency.
