Physiological Adaptations In Coastal Vegetation

Coastal Maritime Forest Florida

Tolerance of drought and the ability to regenerate in disturbed sites are two of the outstanding features of sand dune vegetation. Many of the moss and lichen species, which hold the surface of the sand dunes, have the remarkable property of being able to allow their tissues to dry out without losing viability. After prolonged periods of desiccation (e.g. lying on a herbarium sheet for 70 years ) some moss species begin to resume metabolic activity within 30 minutes of gaining access to water....

Amphibious Plant Adaptations

Climb Assist Devices Oil Rig Tower

Most amphibious herbaceous species in temperate zones are either rhizomatous or tuberous geophytes (plants with their perennating buds below ground) and rely more on vegetative propagation than seed for regeneration. Seed germination is often very low in many amphibious species and successful sexual reproduction takes place only during periods of exceptional drought when water table levels have receded long enough for seeds to germinate and produce established juvenile plants. This restricted...
