Abstract


Seed plays a vital role for establishment of forest plantation and for any afforestation program. Forest and land rehabilitation and community forestry become a great emphasis for Indonesian national forestry programs that make the requirement of seed has multiplied manifold. Seed has become a valuable commodity and thus needs a prudent planning and sophisticated innovated equipment to support seed procurement of high-quality seeds and seedlings. In the last few years, research and development in seed science and technology have made significant progress. Basic problems faced in tree seed procurement in the tropic are seed characters of recalcitrant and intermediate which well known in drastically deteriorated in seed viability and vigor, sensitive to drying process and low storability. Applied technology for improving seed and seedling quality can be conducted by invigoration methods including physical  invigoration (hydro-priming, osmo-priming, matri-conditioning, gamma-ray irradiation and magneto-priming) and physiological invigoration (hormone priming, micronutrient, biopriming, ultra fine bubble). Seed storage technique has been developing for preparation of planting programme and in-situ conservation through seedling storage and cryopreservation. In seed distribution scheme, seed and seedling certifications were developed by compiling the seed testing and seed quality standard in the form of Indonesian Nasional Standard.
