Refrigerated storage helps reduce what aspect of ethylene activity?

Refrigerated storage helps reduce what aspect of ethylene activity?

• A. Increases ethylene production
• B. Reduces ethylene production and action
• C. Has no effect on ethylene
• D. Eliminates ethylene completely

Answer: (B)

Refrigerated storage slows the plant’s metabolism, so ethylene production decreases when materials are kept cold. It also dampens the plant tissues’ responsiveness to ethylene, meaning the hormone’s effects—like accelerated aging and ripening—are delayed. So refrigeration reduces both how much ethylene is produced and how strongly it acts, rather than increasing production, having no effect, or eliminating it entirely. This helps extend vase life and preserve freshness, though trace ethylene can still exist and may have some impact in very sensitive cases.
