General Objective:

The main objective of this proposal is to develop seed storage and germination information for fifty keystone tree species from lowland tropical rain forests in Sri Lanka. These trees provide the fundamental ecological framework upon which these forests and their communities depend. Further, effective long-term storage mechanisms will be developed for ten of the fifty species that represent key seed morphological traits.

Specific Objectives

  1. Identify storage behaviour types of fifty selected species in tropical lowland rain forests in Sri Lanka
  2. Determine low cost storage methods for ten indicative species representing key dormancy states
  3. Determine morpho-chemical changes that occur during the storage of seeds of these species
  4. Determine how recalcitrant and intermediate seeds survive in the field
  5. Construct seed storage behaviour profiles for tropical lowland rain forests species in Sri Lanka
