In botany, drought tolerance is the ability by which a plant maintains its biomass production during arid or drought conditions. [ 1 ] [ 2 ] [ 3 ] Some plants are naturally adapted to dry conditions , surviving with protection mechanisms such as desiccation tolerance , detoxification , or repair of xylem embolism. [ 3 ]
Examples of xerophytes include cacti, pineapple and some gymnosperm plants. The morphology and physiology of xerophytes are adapted to conserve water during dry periods. Some species called resurrection plants can survive long periods of extreme dryness or desiccation of their tissues , during which their metabolic activity may effectively shut ...
Heat tolerance may be displayed alongside cold-hardiness, such as in the American Horticultural Society's "Heat Zones". See Thermoregulation § In plants and Breeding for heat stress tolerance . For drought tolerance , see Drought § Impact on crops and Breeding for drought stress tolerance .
Dryland farming caused a large dust storm in parts of Eastern Washington on October 4, 2009. Courtesy: NASA/GSFC, MODIS Rapid Response [1]. Dryland farming has evolved as a set of techniques and management practices to adapt to limited availability of water, as in the Western US and other regions affected by climate change for crops such as tomato and maize.

His pupil, Theophrastus, in Historia Plantarum (c. 350 BC), was the first who formally recognized plant habits: trees, shrubs and herbs. [ 3 ] Some earlier authors (e.g., Humboldt , 1806) did classify species according to physiognomy, [ 4 ] [ 5 ] [ 6 ] but were explicit about the entities being merely practical classes without any relation to ...
In addition, there are several species of pine under the trees in the vegetation zone. The shrub layer contains numerous herbs such as rosemary, thyme and lavender. In relation to the potential natural vegetation, around 2% of the Earth's land surface is covered by sclerophyll woodlands, and a total of 10% of all plant species on Earth live there.
Such methods include: researching on drought resistant crops, monitoring plant transpiration and reducing soil evaporation. [117] Drought resistant crops have been researched extensively as a means to overcome the issue of water shortage. They are modified genetically so they can adapt in an environment with little water. This is beneficial as ...
