Effects of zinc nutrition and high temperature on the growth, yield and grain quality of wheat locations

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.
