A horticulturist aiming to reduce post-harvest water loss during storage should primarily ____________________ Adjust light quality Spay nutrient rich liquid Induce hormone mediated seed germination Minimize transpiration gradients between fruit tissues and surrounding air 2. Which fruit group contributes most significantly to the global beverage and juice-processing industries? Temperate drupes Aggregate fruits Citrus fruits and grapes Tropical nuts 3. Which of the following management practices is most effective at reducing nitrogen leaching loss in sandy soils? Apply all nitrogen at planting as nitrate Use only phosphorus fertilizers Irrigate heavily immediately after fertilizing Split application of nitrogen matching crop demand 4. _________________ is the most commonly used postharvest parameter as an indirect indicator of fruit sweetness Total Soluble Solids Fruit firmness Relative humidity Titratable acidity 5. Which fruit crop is globally regarded as a model system for studying climacteric fruit ripening and ethylene-mediated physiological changes? Tomato Strawberry Grape Citrus 6. Ethylene is primarily associated with ______________ Nitrogen fixation Water absorption Root growth Fruit ripening and senescence 7. What is the most immediate effect of reducing plant spacing (planting more densely) in an orchard? No change in yield Increased light interception per plant Increased competition among plants for light, water, and nutrients Decreased competition for light 8. Why is nitrogen (as nitrate) more mobile in soil than ammonium (NH₄⁺)? Nitrate is negatively charged and repelled by soil colloids; ammonium is positively charged and attracted Nitrate is larger in molecular size Nitrate is a gas; ammonium is a solid Ammonium evaporates quickly 9. Which of the following is a major disadvantage of transplanting seedlings compared to direct seeding? Poorer crop uniformity Increased risk of root damage and transplant shock Higher seed requirement Longer time to harvest 10. Compared to open-field cultivation, growing of fruit tree nursery in tunnels typically reduces which environmental factor most significantly, thereby limiting photosynthesis? Carbon dioxide concentration Light intensity and quality Soil moisture Wind speed Loading … Question 1 of 10
