Plant resistance to water deficit

Patent Granted Degree of Resistance to drought depend upon crops. Generally three strategies can help a crop to mitigate the effect of drought stress: (a) drought escape (b) drought avoidance (c) drought tolerance A proper timing of lifecycle, resulting in the completion of the most sensitive developmental stages while water is abundant, is considered to be a drought escape strategy. Avoiding water-deficit stress with a root system capable of extracting water from deep soil layers, or by reducing evapotranspiration without affecting yields, is considered as drought avoidance.
