What is the term used to describe a plant’s ability to tolerate drought?

Drought resistance is the term used to describe a plant's ability to withstand periods of water scarcity and effectively manage its water usage during these times. Plants that exhibit drought resistance have developed various physiological and morphological adaptations that allow them to survive with limited moisture. These adaptations may include deeper root systems, which help access water sources below the surface, or specialized leaf structures that reduce water loss through transpiration.

Drought resistance encompasses both enduring prolonged dry conditions and recovering after periods of drought. Understanding this term is critical for horticulturists and nursery technicians, as it helps identify suitable plant species for regions prone to low rainfall and informs practices aimed at conserving water in landscaping and gardening.

While water dependency highlights a plant's need for consistent moisture, climate resilience refers to the overall capacity of a plant to adapt to varying climate conditions, not specifically drought. Soil adaptation speaks to how plants adjust to different soil types and conditions, but it does not specifically address their tolerance to water scarcity. Thus, drought resistance correctly encapsulates the characteristic being inquired about.
