Seed zinc content influences early vegetative growth and zinc uptake in oilseed rape locations
Aims

To assess the impact of seed zinc content on vegetative growth and zinc uptake of Brassica napus and B. juncea.

Key messages
  • Low-zinc seed and high-zinc seed oilseed rape genotypes were sown in pots containing zinc-deficient siliceous sand fertilized with low or high zinc supply in a controlled environment.
  • After six weeks, plants derived from the high-zinc seed had better seedling vigour, increased root and shoot growth, more leaf area and chlorophyll concentration in fresh leaf, and higher zinc uptake in shoot compared to those from low-zinc seed at low zinc supply .
  • The influence of high-zinc seed was dissipated at high zinc supply.
  • The results demonstrate that although oilseed rape has very small seeds compared with wheat, zinc reserves present in seed still have a strong impact on early vegetative growth and zinc uptake in zinc-deficient soils.
  • The results suggest that sowing high-zinc seed coupled with growing zinc-efficient genotypes may help in sustaining the production of oilseed rape in zinc-deficient soils.
