drought tolerance的意思|示意

Drought tolerance refers to a plant's ability to survive and remain productive in arid or drought-prone environments. Drought tolerance is an important trait for plants in areas where water availability is limited and unpredictable.

Drought tolerance is achieved through a variety of methods, including deep root systems, thick waxy cuticles on leaves, water-storage tissues, and closure of stomata on leaves. Plants with drought tolerance are able to limit water loss, conserve available moisture, and better utilize available water.

Drought tolerance is an important trait for crop plants that must withstand dry weather during key growing periods. Breeders have identified drought tolerant varieties of many crops such as corn, wheat, and rice. These varieties are often bred specifically to be able to produce high yields in dry conditions.

The use of other methods to increase drought tolerance in crops includes irrigating soils to increase soil moisture levels, timing planting to take advantage of wet weather, and using drought-resistant cultivars. In some cases, farmers may also consider planting cover crops or utilizing mulch to retain more moisture in the soil.

In addition to being important for crop production, drought tolerance is a desirable trait for landscape plants, particularly in areas that experience extended dry periods. Planting drought tolerant species will ensure that plants will survive and remain attractive even during dry times.
