Of all, 16, 30 and 2 species comprised top, mid and lower-canopy status, respectively and most of them exhibited poor regeneration in the forest. doi=rjf.2013.1.15 INTRODUCTION The tropical forests occupy 7% of the earths area with about half of the worlds forest cover and 65% of global biodiversity (Whitmore, 1990).

Overall, the mid-canopy species were noted to have shown hher seed germination and prolonged viability. Seed Germination in Lowland Tropical Rainforest Trees: Interspecies, Canopy and Fruit Type Variations. In Asia and the tropics, tropical forests have been foremost victims of anthropogenic pressure to the extent that most areas either replaced by secondary vegetation or denuded completely (Menon et al., 2001). Downloadable guide to seed biology, the collection, storage and germination of tropical tree seeds.
Cover and Frontmatter — Reforestation, Nurseries and Genetics. Considering that, tropical forests are under threat, it is expected studies regarding seed germination will enable successful nursery operations and planned seedling production. For sound management and continued economic gains from tropical forests, it is desired to assess reproductive seed biology of native tree species that contribute considerably to local biodiversity as well as also valued by the indenous people (Hubbell and Foster, 1983; Deb and Sundriyal, 2008). Jan 11, 2005. The Tropical Tree Seed Manual is a one-volume reference manual for students. to give students, cians, and scientists a thorough understanding of tropical tree seeds.

Seed Germination in Lowland Tropical Rainforest Trees. Also this will enhance the establishment of seedlings in the restoration activities of degraded sites through selection of native plants. Our understanding of tropical tree seeds has advanced considerably over past two decades, however only selected species are used in afforestation because of eases in their seed collection and management (viz., Acacia, Casurina, Eucalyptus, Leucena, etc.) (Smith et al., 2002). May 22, 2013. Tropical trees exhibit wide heterogeneity in their canopy status, fruit types, seed sizes and seed-size dependent seedling growth; information.

Pentaclethra macroloba Willd. Kuntze It is, therefore, desirable to screen and evaluate more and more native species for their germination and viability so that some of such species could also form a part in plantation schemes (Wang, 1991; Naithani et al., 2004). Emergent tree, which is dominant in the canopy of the humid tropical forests. It reaches 30. bark and seed should be studied to verify the toxicity and medicinal.
