MULTIPURPOSE TREE & SHRUB SEED DIRECTORY |
A Multipurpose Tree & Seed Directory by Peter G. von Carlowitz was published by the International Council for Research in Agroforestry (ICRAF) in May 1986. |
It gives information on suppliers of some 700 multipurpose woody species (97 seed suppliers in 42 countries). |
For each species, the following information is given: quantities of seed available for distribution (bulk or research), price, seed weight, germination percent and pretreatment. |
The information on seed suppliers includes: institutional type (commercial, governmental, etc.), certificates provided by the supplier and required from the requesting institute (e.g. on provenance, phytosanity, purity and viability). |
In addition to this core information, the Directory provides some useful assistance in the selection of species through schematic description of climate, soil conditions, reproduction, management and uses for 115 species. A useful addition would have been species-specific references to important literature, e.g. as given in Oxford Forestry Institute's Tropical Forestry Paper No. 15: A Guide to Species Selection for Tropical and Sub-Tropical Plantations (Webb et al., 2nd ed. 1984), which includes more than half of the species described in the ICRAF Directory. |
The Directory also has a masterlist comprising almost 1 400 multipurpose woody species and their reported uses; plus a chapter on microsymbionts for nitrogen-fixing trees. |
Altogether a useful, priced publication available from: |
