Vol.15 no.2, 2000

  • Cover picture: Clockwise, from left: (1) Zizania aquatica (background) and Nelumbo nucifera (foreground) in Kenilworth Aquatic Garden, Washington, DC (M. A. Leck). Two seed strategies are represented by these wetland species: Z. aquatica has short-lived recalcitrant seeds that do not tolerate drying, and N. nucifera has long-lived orthodox seeds within a water-impermeable nut (physical dormancy). The N. nucifera plants are from two fruits germinated in 1951 that were collected from an ancient lake bed deposit in Pulantian, Manchuria, northeast China. (2) The recalcitrant seed of Rhizophora mucronata, with viviparous germination, develops an elongated hypocotyl that can reach almost a meter in length (N. W, Pammenter and P. Berjak). (3) Scrub-heather in southwestern Australia. This region contains about half of the world's estimated 1200 serotinous species. In the foreground is Banksia hookeriana, whose 'cones' of woody follicles retain viable seeds for up to 15 years; it is the most intensely studied of all serotinous species (B. B. Lamont). (4) Smoke from burning vegetation, such as South African fynbos shown here (J. Van Staden), contains a chemical signal that triggers seed germination.
