Understanding drought tolerance in plants - Ahanger - 2021 ...
网页2021年5月27日 · Drought tolerance involves metabolic and hydraulic readjustment at the cellular and whole plant level, combined with finely regulated signalling events. Several key metabolic and physiological adaptations in response to drought tolerance in xero-halophytic plants have been identified (Panda et al. 2021 ).
Drought Tolerance Strategies in Plants: A Mechanistic Approach
网页2020年6月22日 · Drought tolerance and drought avoidance are the major strategies of plants against water deficit stress. Drought tolerance is the ability of plant to resist dehydration through various physiological activities, such as osmotic adjustment via …
Drought tolerance - Wikipedia
网页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] .
