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

TerminologyOnline Farm Trials: a web-based information system that provides open and free access to agricultural-based research trial data and information. OFT is a digital online resource managed through a collaboration between the Grains Research and Development Corporation (GRDC) and the Centre for eResearch and Digital Innovation (CeRDI) at Federation University Australia (FedUni).
Trial Contributor: an individual or organisation (e.g. grower group, research centre, commercial entity or government department) that makes data and/or other information available through OFT.
Metadata: information about Trial Projects submitted to OFT (e.g. names of the Trial Contributors, Trial Project title, Trial site location, Crop type(s), Growing season year(s), Trial type and Trial design). This data is compiled by OFT from information submitted with Trial Projects.
Trial project data and information: any attachment (documents and other files, e.g. PDFs, photos, videos, maps, reports and data files) submitted to OFT by Trial Contributors.

Plant Breeders’ Rights (PBR)
Some crop varieties used in research trials may be covered by Plant Breeders' Rights (PBR). Users should confirm PBR status of relevant varieties by searching the IP Australia PBR database, http://pericles.ipaustralia.gov.au/pbr_db/ or Variety Central (http://varietycentral.com.au/) and contacting variety owners for further information if required. Where possible, varieties have been listed according to their registered PBR name, although OFT cannot and does not guarantee that the information is accurate or complete.
Note that PBR cover is administered through the Plant Breeders’ Right Act 1994 (https://www.legislation.gov.au/Series/C2004A04783).
