Aims

To examine relationships between zinc sufficiency and tolerance to heat stress in wheat.

Key messages
  • Glasshouse experiments and field experiments in South Australia and Victoria were conducted to examine wheat tolerance to heast stress as related to zinc nutrition.
  • The results showed that good zinc nutrition could preserve membrane integrity and photosynthesis during heat stress.
  • Supplementary zinc nutrition was shown to increase canopy cooling through evaporation.
  • The field and glasshouse experiments showed that the combinaiton of heat stress and poor zinc nutrition were more damaging when they occurred together.
  • Zinc sufficient plants had higher quality grain (glutenin:gladin) and better bread making qualities.
