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