Seed limitation in an Amazonian floodplain forest

Ecology, 2019
AbstractWe monitored a close‐spaced grid of 289 seed traps in 1.44 ha for 8.4 yr in an Amazonian floodplain forest. In a tree community containing hundreds of species, a median of just three to four species of tree seeds falls annually into each 0.5‐m2 establishment site. The number of seed species reaching a given site increased linearly with time for

Synthetic seeds in forest trees

1993
Artificial seed consists of somatic embryos surrounded by a protective coating. The coating around the somatic embryo provides the necessary protection during storage, handling and mechanical planting. The artificial seed may contain nutrients to provide the energy required for germination which is normally supplied by endosperm or female gametophyte ...

Genetics and Forest Seed Handling

2016
High genetic quality seed is obtained from seed sources that match the planting site, have a good outcrossing rate, and are superior in some desirable characters. Non-degraded natural forests and plantations may be used as untested seed sources, which can sometimes be managed to promote outbreeding and increase seed production.
