Postharvest Technology MCQs (Set 14) Posted on August 24, 2026Author agropublishers 0 1. Which packaging function primarily prevents bruising, abrasion, puncture, and crushing of fresh produce? Containment Communication Marketing Protection 2. Why can reducing mechanical damage be more effective for postharvest disease management than applying fungicides after harvest? Wounds inhibit pathogen development Mechanical damage has no relationship with infection Many postharvest pathogens depend on wounds as primary infection courts Fungicides increase wound formation 3. Loading warm produce into a refrigerated truck can result in __________________ Reduced respiration immediately Excessive refrigeration load and difficulty maintaining the desired temperature Immediate uniform cooling Improved shelf life 4. Which postharvest practice effectively reduces transpiration and maintains fruit freshness? Increasing air movement Using appropriate packaging to reduce water loss Increasing storage temperature Removing all packaging 5. Ventilation holes in fresh-produce cartons primarily facilitate _____________ Heat removal and refrigerated-air circulation Complete prevention of water loss Elimination of respiration Increased mechanical injury 6. ________________________ is a new disease attack that develops after the initial disease has become established Mechanical infection Systemic infection Latent infection Secondary infection 7. Excessive ventilation in a fresh-produce package may result in ____________________ Anaerobic respiration Increased shelf-life in every commodity Increased moisture loss and shrivelling Complete elimination of decay 8. Overfilling a carton of mangoes is most likely to cause ___________________ Compression injury and bruising Reduced package weight Improved ventilation Reduced compression 9. The primary purpose of packaging fresh horticultural produce is to _____________ Eliminate the need for refrigeration Protect, contain, facilitate handling, and preserve quality Increase crop yield Increase produce respiration 10. Among the environmental factors _____________ and ____________ are primarily important in the development and spread of postharvest diseases Soil pH and texture Temperature and relative humidity Light and photoperiod Wind speed and photoperiod Loading … Question 1 of 10
