Germination and plant development of Sideroxylon capiri (ADC) Pittier: Sapotaceae
Seeds were collected from 6 trees of Sideroxylon capiri in the Barra National Park at Nicoya in Costa Rica in April 1996, and germination and seedling development studied starting in May, after sowing at 3 sites at different altitudes (40, 400 or 1200 m). The seeds were either buried at 2 cm depth or placed on the surface of soil or soil plus or minus (forest) litter, either under shade (all sites) or in full sun (the lowest site). There was no germination in the 2 tests in full sun at the lowest site where the seeds were placed on the substrate (soil + litter, or soil mixed with limestone). Germination varied between 50 percent (at the highest site, in shade), 68 percent (at the lowest site, in full sun), 76 percent (at the medium-altitude site, in shade) and 83 percent (at the lowest site, in shade) in the other tests, in all of which the seeds were buried. Details are given of plant development over 70 (roots) or 100 (shoot height) days after sowing. Best growth was in the seeds which germinated most and fastest, at the thelowest site, in the shade.
