Which statement best describes postharvest physiology?

• A. Postharvest physiology focuses on seed development.
• B. Postharvest physiology studies metabolic changes in harvested plant material.
• C. Postharvest physiology studies photosynthesis during growth.
• D. Postharvest physiology is unrelated to water status.

Answer: (B)

Postharvest physiology focuses on what happens to plant tissues after they are harvested, including metabolic changes, respiration, aging, and how storage conditions affect quality and shelf life. The statement describing this field as studying metabolic changes in harvested plant material captures the essence, because metabolism continues after harvest and drives processes like ripening, deterioration, and texture changes. Other ideas mix in preharvest processes or incorrect relationships. Seed development happens before harvest, not after. Photosynthesis is a growth-stage process before harvest. Water status is highly relevant postharvest—loss of moisture, humidity, and atmosphere conditions strongly influence quality—so saying it's unrelated wouldn’t fit.
