Effects of zinc on photosynthesis and yield of wheat under heat stress locations
Aims

Examine the interaction between zinc nutrition and heat stress on the photosynthetic activity and grain yield of wheat plants under both field and growth room conditions.

Key messages
  • We examined the interaction between zinc nutrition and heat stress on the photosynthetic activity and grain yield of wheat plants under both field and growth room conditions.
  • The zinc inefficient cultivar Goldmark was found to have an improved chlorophyll fluorescence ratio (Fv/Fm), a measure of injury to photosynthesis, under heat stress when supplied with elevated levels of zinc compared to plants where less zinc was applied.
  • However supplementary zinc did not prevent a decline in kernel weight or grain yield under high temperature conditions.
  • The results indicate that supplementary zinc nutrition, in a zinc inefficient genotype at least, can provide thermotolerance to the photosynthetic apparatus of wheat.
