Effect of cultivar, seed source and manganese supply on growth and manganese uptake of wheat (Triticum aestivum) locations
Aims

To monitor varietal performance during the 1982/83 season and conduct controlled environment studies to determine more precisey the extent of genetic variation within wheat for Mn efficiency.

Key messages
  • Plants grown in small pots containing Mn deficient calcareous (pH 8.5, 80% CaCO3) sand collected from Wangary, S.A with 0-50 ppm added Mn in growth room at 15°C.
  • Plants harvested at approx. 4 weeks (early tillering). Also 30 wheat cultivars were screened at Wangary using plant breeders' plots (4 rows x 5 m) with a split plot application of foliar MnSO (1 kg/ha ).
  • Effects of seed soaking were evaluated for wheat and barley by soaking for 6 h with 1.5% MnSO4 prior to sowing.
  • Without Mn, all cultivars showed no differences in growth and Mn uptake at 4 weeks (pots) but significant differences at 8 weeks in the field. With Mn supplied either in soil or on seed large cultivar differences were apparent at 4 weeks.
  • Conclude that use of Mn efficient varieties coupled with a suitable seed Mn content will lessen the need for Mn fertilisers.
