The most likely consequence is ________________________ Restricted airflow and poor heat removal Improved cooling Reduced respiration Increased ventilation efficiency 2. Which postharvest factor can strongly influence the rate of fruit ripening and senescence by affecting ethylene action? Temperature Rainfall Seed size Photosynthesis type 3. Harvesting containers should not be overfilled ________________________ To prevent crushing of produce in lower layers To increase respiration To increase water loss To accelerate cooling 4. Which quality attribute can be maintained by gibberellin treatment during postharvest storage? Flesh firmness Fruit decay Seed dormancy Root growth 5. An infection that occurs in the field but becomes visible only during ripening or storage of fruits is called ______________ Latent infection Mechanical infection Secondary infection Systemic infection 6. Freshly harvested produce should be protected from direct sunlight _____________________ To reduce sunburn and additional field heat To increase field heat To increase water loss To accelerate ripening 7. Blue mold of apple is commonly associated with _________________, which causes major postharvest decay and soft rot in stored fruit Penicillium expansum Botrytis cinerea Rhizopus stolonifer Alternaria spp. 8. A package with rough internal surfaces presents a high risk of ___________________ Abrasion and skin damage Chilling injury Anaerobic respiration Ethylene removal 9. Which condition is an important physiological disorder associated with low-temperature storage? Chilling injury Sunscald Powdery mildew Bacterial soft rot 10. _________________________ is the most suitable harvesting container for minimizing mechanical damage to harvest fruits Smooth-interior, cloth-lined container Rough metal container Deep unlined bin Overfilled basket Loading … Question 1 of 10
