INTERNATIONAL PROVENANCE TRIALS:
ACACIA MANGIUM

Seed availability for international testing of Acacia mangium from Australia, Papua New Guinea and Indonesia was reported in Forest Genetic Resources Information number 11 (Page 48); information on this has also been distributed to potentially interested member governments of FAO through a circular letter dated 31 January 1983.
To date, seed for these international trials, coordinated by FAO's Forestry Department/ the Seed Centre of CSIRO's Division of Forest Research, has been distributed to 43 Institutes for the establishment of experiments on more than one hundred sites.
Some seed is still available for testing. Interested countries which have not yet requested seed should write expressing their interest to the Seed Centre, CSIRO Division of Forest Research, P.O. Box 4008, Canberra A.C.T. 2600, Australia; with a copy of the request addressed to the Director of the Forest Resources Division of FAO (Via delle Terme de Caracalla, I-00100 Rome, Italy).
The following information should be provided:
  1. Do you wish to establish trials on more than one site, and if so how many?
  2. Do you wish to test the basic set of 8 provenances, the full set of 16 provenances (subject to availability), or a combination of these?
  3. What are the latitude, Longitude, altitude and climatic conditions of each proposed experimental site?
  4. Have species or provenance trials of A. mangium already been successfully established on the proposed sites or similar ones? If so, what are the indications of these trials?
  5. In which month would you wish to receive the seed?
  6. Are import permits required for research quantities of tree seed?
The trial design proposed is complete randomised blocks with 36- tree plots and 5 replications. Recommended spacing is 3 × 3 meters.
