A ____________________ spreads throughout the vascular or internal plant system Mechanical infection Secondary infection Latent infection Systemic infection 2. Which situation presents the greatest risk of rapid postharvest disease development? Bruised fruit stored under warm, humid conditions Intact fruit stored at low relative humidity Rapidly cooled undamaged fruit Properly cured bulbs under appropriate conditions 3. Proper packaging of fruits and vegetable contributes to postharvest disease management mainly by _____________ Increasing contamination Preventing mechanical injury and compression Raising water loss Increasing bruising 4. Plant pathogen __________ causes gray mold on many fruits and vegetables Rhizopus stolonifer Botrytis cinerea Penicillium expansum Fusarium oxysporum 5. Cold storage reduces postharvest decay of fruits, mainly because low temperature ___________________ Speeds pathogen growth Slows respiration and the growth of many pathogens Always causes freezing injury Eliminates the need for hygiene 6. Ethylene management is particularly important in postharvest handling because ethylene _______________ Regulates ripening in climacteric fruits Increases water content Stops respiration completely Prevents all microbial growth 7. NIR spectroscopy is particularly useful for non-destructive estimation of __________________ of fruits Insect species by visual observation Dry matter, total soluble solids (TSS), moisture, and maturity Package design Fruit weight 8. Which novel preservation technology can preserve fresh-cut vegetables with minimal heat damage? Boiling and room-temperature storage Sun drying and cloth-bag storage High-pressure processing (HPP) of refrigerated products Traditional high-temperature canning 9. Which group consists of non-climacteric fruits? Strawberry, grape, citrus Banana, mango, papaya Apple, pear, tomato Mango, banana, apple 10. During dehydration of sliced tomatoes, which adjustment can help prevent case hardening? Start at a lower drying temperature with good airflow Increase the drying temperature further Add more salt before drying Reduce airflow to keep the surface moist Loading … Question 1 of 10
