Excessive temperature fluctuations Delayed handling Proper postharvest handling Mechanical injury 2. Postharvest chilling injury is particularly important because it can ____________________ in chilling-sensitive horticultural priducts Cause physiological damage Improve fruit quality Increase mineral uptake Accelerate photosynthesis 3. Which strategy can help reduce postharvest losses through genetic improvement? Selecting cultivars with rapid senescence Selecting genotypes with poor keeping quality Selecting cultivars with high respiration rates Selecting genotypes with longer postharvest life 4. Reducing postharvest losses can contribute directly to food security by ________________ Reducing crop diversity Increasing the cultivated area Increasing fertilizer consumption Increasing the amount of food available for consumption 5.
