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