GOMEZ RESTREPO, Martha Ligia. ESTIMATE OF THE GERMINATIVE CAPACITY AND THE VIGOR OF DIOMATE SEEDS (Astronium graveolens Jacq.) SUBJECTED TO DIFFERENT TREATMENTS AND STORAGE CONDITIONS. Rev. Fac. Nac. Agron. Medellín [online]. 2004, vol.57, n.1, pp.2218-2232. ISSN 0304-2847.

Two studies of diomate seeds (Astronium graveolens Jacq) were conducted. The first was conducted to determine the effect that substrate and light condition has on germination. The second was to evaluate the germinative response of seeds stored over differing time periods and under temperature and packaging conditions. The diomate seeds sowed in full exposure in soil substrate had the greatest germinative potential, the fastest germination times and the highest vigor. The total loss of vigor in the seeds varied according to time and temperature of storage, as follows: after a month of storage at temperatures between 7 and 10°C, after six months of storage at temperatures between 20 and 33°C and after eleven months of storage at ambient temperatures between 12 and 18°C. The type of packing did not significantly influence the final results.
