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