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