Why are flowers generally harvested in the early morning?

• A. They are less likely to bruise when cut
• B. Pesticide residue is minimized
• C. Faster dehydration occurs during the night
• D. Higher carbohydrate levels in the evening and early morning, so they last longer due to stored energy

Answer: (D)

Harvesting flowers in the early morning matches the plant’s state when they are most ready to cope with the stress of cutting and transport. Overnight respiration leaves the tissues with energy reserves, so the flowers start with substantial carbohydrate stores that can be used right after harvest. Those stored sugars provide readily available energy to maintain cellular functions, helping petals stay turgid and delaying wilting as the plant adjusts to being cut. That energy reserve is a key factor in extending vase life, making morning harvests more favorable. The other ideas don’t line up as well with how plants behave. Bruising depends more on handling and cutting technique than the time of day; pesticide residues aren’t reliably minimized by harvest time; dehydration is reduced at night because stomata are less active, so the claim that dehydration occurs faster during the night isn’t accurate.
