Effects of boron toxicity upon the mineral nutrient composition of barley and wheat cultivars locations
Aims

To examine how boron toxicity affects growth and nutrient composition of several barley and wheat cultivars.

Key messages
  • Several barley and wheat cultivars displaying a broad range of tolerance to boron toxicity were cultured in solution culture at boron concentrations from adequate to toxic.
  • Tolerant cultivars developed fewer symptoms, grew better and absorbed less boron than sensitive varieties.
  • The supply of boron had no consistent effects on the tissue concentration of macronutrients (K, S, Mg, P, Ca) and trace elements (Cu, zinc, Mn, Fe).
  • There appeared to be no interaction between boron and other elements.
  • It was concluded that differences between cultivars in tolerance related to the amount of boron absorbed.
