Stress tolerance
The ability of agricultural crops to maintain productivity and viability when exposed to adverse environmental conditions.
Также говорят: adaptability, resistance, stress resilience
Plant stress tolerance refers to the capacity of a crop to withstand abiotic factors such as drought, extreme temperatures, or soil salinity without significant yield loss. Enhancing this trait is essential for securing harvests in volatile growing seasons.
In field operations, growers improve stress tolerance by selecting resistant germplasm and applying bio-stimulants or specific nutrients that strengthen plant physiological defenses. Early intervention with growth regulators can help plants adjust their metabolism to impending environmental pressure.
A common management mistake is relying solely on chemical treatments while neglecting soil structure and moisture management. Over-application of fertilizers during stress periods can induce osmotic shock and further weaken the crop's natural defense mechanisms.
