Project

Title: Ecophysiology of early seedling growth and development for the effective translocation of seed-based propagules for restoration of seagrass (Posidonia australis) in Cockburn Sound.
University: University of Western Australia.
Supervisors: Kingsley Dixon, Director, Science, Kings Park and Botanic Garden, West Perth, 6005; Gary Kendrick, The University of Western Australia, Nedlands, 6009.
Industry sponsors: Cockburn Cement
Project Description:
Research will investigate a recent breakthrough in use of Posidonia seed as a source of propagules for restoration of seagrasses in Cockburn Sound. For the first time, Posidonia seed can be germinated, grown and manipulated under controlled tank conditions. These early-growth seedlings then provide an ideal source of transplant seedlings for translocation and restoration research. In addition, tank-cultured seedlings will enable intensive investigation into the physiology of early establishment requirements of seedlings including nutrient and light quality impacts on seedling growth and development and role of pore water nutrients in plant nutrient uptake.
By relating responses to these parameters to field grown seedlings it is anticipated that factors limiting growth, establishment and survival of seedlings under restoration conditions can be researched and management systems developed to optimise the use of seed base recruits for large scale restoration.
The research program aims to:

  • Improved understanding of key ecophysiological parameters eg light quality and nutrients and their impact upon early seedling establishment.
  • Development of technology for effective transplanting of high-health seedlings for restoration activities.
  • Improved understanding of the phenology of growth and development of seagrass seedlings through to maturity under controlled environmental conditions.
