Zinc efficiency as related to distrubution and internal requirement locations
Aims

To investigate whether higher Zn efficiency in wheat was related to lower Zn requirement and/or greater distribution to younger parts.

Key messages
  • Compared some of the physiological differences in two bread wheat genotypes (Stylet (Zn-efficient) and VM506 (Zn-inefficient).
  • Results indicate that higher zinc efficiency may be achieved through greater distribution to younger parts and lower internal requirement.
  • Selection for such attributes can be considered in breeding programs aiming to develop zinc efficient genotypes for cropping zinc deficient soils.
