More about forest reproductive material
Danida Forest Seed Centre (DFSC) publications
DFSC has published a wide range of papers and leaflets which are very valuable resource - many are must-reads for any tree seed project. The series presents new or adapted techniques and methodologies, and descriptions of equipment. They also include popular editions of the results of DFSC's own research and development work, as well as results from other institutions. Some of the notes have previously been published elsewhere. They are grouped under the following headings:
- case studies: application of guidelines and technical notes in specific area;
- results and documentation: publication of analyses of e.g. provenance trials, carried out between DFSC and other institutions;
- guidelines and technical notes: a continuation of DFSC's technical notes series giving guidelines for a range of subjects useful to all our readers. Topics include: seed collection and processing; seed testing, storage and pretreatment; seed health and international transfer of seed; nursery techniques; tree improvement and gene conservation; and management;
- lecture notes: these are primarily compilations intended for training courses, presenting more comprehensive information on aspects of seed procurement, tree improvement and gene-resource conservation. Each note may be read independently. Topics include: general introduction; seed sources; tree improvement and gene conservation;
- species leaflets: aimed at seed technicians, extension workers and farmers, these two-page leaflets contain information on practical seed handling for some 65 tree species. All leaflets are available in English, some also in Spanish.
Guide to handling tropical and subtropical forest seedSchmidt, L. 2000
Danida Forest Seed Centre. 511 pp.
An essential must-read guide for anyone working on tropical and subtropical seed. The chapters cover: seed biology, development and ecology; planning and preparation for seed collections; seed collection; fruit and seed handling between collection and processing; seed processing; phytosanitary problems and seed treatment; seed storage; dormancy and pretreatment; germination and seedling establishment; seed testing; genetic implications of seed handling; microsymbiont management; seed documentation; and trade and transfer of forest seed. The publication largely supersedes the DFSC/FAO publication A guide to forest seed handling.

Recent advances in tropical tree seed technology and planting stock production
Proceedings: International Symposium,
12 - 14 June, 1995, Haad Yai, Thailand.
Tapa, A.C. (Ed.) 1996.
ASEAN Forest Seed Centre, Muak-Lek, Thailand.
There are some 40 papers grouped under the following headings: high quality seed for high quality planting stock; seed quality: collection, handling and processing; seed quality; storage, testing and certification; production of high quality seedlings: physiology, morphology, and standardization; alternative planting stock techniques; beneficial stock production techniques.
General papers stress the need for top quality seed to endure high quality planting stock and the need to carefully plan and implement seed collection, handling and storage activities. Specific papers deal with various techniques to improve the storage and viability of some tropical species.
Genetic conservation and production of tropical forest tree seed
Proceedings: International Symposium,
14 - 16 June, 1993, Chiang Mai, Thailand.
Drysdale, R.M.; John, S.E.T. & Yapa, A.C. 1994.
ASEAN-Canada Forest Tree Seed Centre, Muak-Lek, Saraburi, Thailand.
Papers on the genetic conservation theme highlight many controversial issues concerning: development vs conservation; conservation and forest management; and strategies for in-situ and ex-situ conservation. Papers on seed production are of a practical "how-to" type, with several case studies.

USDA-FS woody plant seed manualPublication of the handbook on seeds of trees and shrubs, produced by the USDA Forest Service, the Woody plant seed manual (USDA misc. publ. 654) included 420 taxa in 140 genera. An updated and expanded manual, Seeds of woody plants in the United States (USDA Agric. handbk. 450) was published in 1974, containing data for approximately 800 taxa in 188 genera. Advances in tree seed technology in the last quarter-century have dictated the publication of a new revision, also named the Woody plant seed manual. The revision process by a team of Forest Service scientists and cooperators from universities and other government agencies is now underway. The book will contain almost 1,300 taxa in 230 genera. When complete, the manual will be formatted and made available as a traditional printed book and electronically on a CD-ROM and the final website in Adobe PDF format.
As parts of the manual become available, they will be made available on the following Web site:http://wpsm.net
