A xerophyte (from Ancient Greek ξηρός (xērós) 'dry' and φυτόν (phutón) 'plant') is a species of plant that has adaptations to survive in an environment with little liquid water. Examples of xerophytes include cacti , pineapple and some gymnosperm plants.
They can tolerate burial in as much as 3 feet (0.9 m) of sand; sand burial stimulates the rhizomes to grow vertically, and is essential to plant vigor. [9] The beachgrass species are also very good examples of xerophytes, being able to thrive on arid to semi-arid beach dunes. The plant has several mechanisms for adapting to heat stress or wind.
The term osmophile, or osmotolerant, is typically applied to microorganisms that can grow in solutions with high solute concentrations (salts, sugars), such as halophiles. The common food preservation methods of reducing water activity ( food drying ) may not always be sufficient to prevent the growth of xerophilic organisms, often resulting in ...
The Ammophila grasses are widely known as examples of xerophytes, plants that can withstand dry conditions. Despite their occurrence on seacoasts, Ammophila grasses are not particularly tolerant of saline soils; they can tolerate a salinity of about 15 g/L (1.5%), which makes them "moderate halophytes". [4]
Tumbleweeds thrive in disturbed soil and are a major contributor to native plant extinctions and wildfires, being highly flammable and bouncing over or rapidly growing in land cleared of vegetation between fields or areas of forest as firebreaks. Despite over a century of cooperation between Mexican, Canadian, and US governments to combat the ...
