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 ]
See Thermoregulation § In plants and Breeding for heat stress tolerance. For drought tolerance, see Drought § Impact on crops and Breeding for drought stress tolerance. For flood tolerance, see cited review. [8] The mechanisms of wind tolerance are still poorly understood. Wind not only causes mechanical stress, but also makes the plant ...
A drought is a period of drier-than-normal conditions. [1]: 1157 A drought can last for days, months or years. Drought often has large impacts on the ecosystems and agriculture of affected regions, and causes harm to the local economy.
In some areas, terms such as water-conserving landscaping, drought-tolerant landscaping, and smart scaping are used instead. The use of plants whose natural requirements are appropriate to the local climate is emphasized, and care is taken to avoid losing water to evaporation and runoff. However, the specific plants used in xeriscaping vary ...
Los Angeles gardens and landscapes won't support the environment and threatened wildlife unless they use native plants. Low water use isn't enough.
Resistance to drought is a quantitative trait, with a complex phenotype, often confounded by plant phenology. Breeding for drought resistance is further complicated since several types of abiotic stress, such as high temperatures, high irradiance, and nutrient toxicities or deficiencies can challenge crop plants simultaneously.
While some concepts, such as pollinator gardens and drought-tolerant plantings, have been trending for several years, other designs, such as the use of bold color, are just beginning to take off ...
A drought watch does not mean that there is currently a drought. Instead, this is when a focus is placed on voluntary water use reductions and spreading awareness about conservation throughout the ...
