Proper postharvest handling Excessive temperature fluctuations Mechanical injury Delayed handling 2. Which postharvest disorder of apples received considerable research attention because of its relationship with storage conditions? Bacterial wilt Superficial scald Tipburn Blossom-end rot 3. Postharvest chilling injury is particularly important because it can ____________________ in chilling-sensitive horticultural priducts Increase mineral uptake Accelerate photosynthesis Cause physiological damage Improve fruit quality 4. Which postharvest effect of gibberellin treatment is most desirable for extending the storage life of horticultural crops? Increased respiration Enhanced tissue softening Delayed ripening and senescence Accelerated ripening 5. Which postharvest stress can be alleviated by gibberellin treatment in cold-sensitive horticultural crops? Chilling injury Drought stress Nutrient deficiency Heat stress 6. Reducing postharvest losses can contribute directly to food security by ________________ Reducing crop diversity Increasing the amount of food available for consumption Increasing the cultivated area Increasing fertilizer consumption 7. The discovery of the climacteric phenomenon and studies of respiration established the foundation of modern _____________________ Olericulture Postharvest physiology Food chemistry Floriculture 8. Postharvest physiological disorders differ from pathological disorders because physiological disorders are primarily __________________ Always caused by insects Caused exclusively by fungi Caused exclusively by bacteria Non-infectious disorders 9. Which strategy can help reduce postharvest losses through genetic improvement? Selecting genotypes with poor keeping quality Selecting cultivars with rapid senescence Selecting genotypes with longer postharvest life Selecting cultivars with high respiration rates 10. Which nutritional component can have its postharvest decline delayed by gibberellin treatment? Protein and nitrogen Vitamin C Cellulose Starch Loading … Question 1 of 10
