Differences in plant hardiness due to regional adaptations are called:

Differences in plant hardiness due to regional adaptations are called:

• A. Acclimation
• B. Provenance
• C. Variety
• D. Survival

Answer: (B)

Regional variations in hardiness come from the geographic origin of the plant material, which is called provenance. Provenance reflects how populations from different regions have adapted to local climates and winter conditions, so a plant from a colder provenance tends to be more winter-hardy in cool areas. Acclimation is the plant’s short-term physiological adjustment to current conditions, not an inherited regional difference. A variety is a cultivated genetic form, not specifically tied to regional adaptation. Survival describes the outcome, not the source of the hardiness differences.
