Naphthalene acetic acid (NAA) delays apple fruit drop primarily by ______________________ Breaking dormancy Increasing respiration Increasing ethylene production Preventing abscission layer formation 2. Windbreaks are established in orchards primarily to ____________ Increase pollination Reduce wind damage and moisture loss Increase sunlight interception Improve rootstock compatibility 3. How do triploid seedless bananas typically propagate in agriculture despite their meiotic sterility? They undergo apomixis, where seeds form clonally without fertilization in every fruit They rely on wind-dispersed pollen to generate new triploid offspring each generation They produce abundant viable seeds that farmers plant every season They are propagated vegetatively using suckers, rhizomes, or tissue culture 4. Anthesis is the stage at which ______________ Seed germinates The flower opens Fruit matures Pollination is completed 5. Abscisic acid (ABA) is primarily associated with ____________________________ Root formation Stomatal closure and drought response Fruit thinning Cell division 6. Plant growth regulator _________________ is most often used to promote uniform flowering and increase fruit set in mango by breaking bud dormancy Paclobutrazol Cytokinins Ethephon Naphthalene acetic acid 7. Which propagation method maintains varietal purity? Vegetative propagation Seed propagation Open pollination Mutation breeding 8. A cultivar is best described as _______________________ A cultivated variety selected for desirable traits A genetically modified plant A naturally occurring wild species A hybrid rootstock 9. Excessive fruit load generally produces fruits that are _________________ Resistant to diseases Larger and sweeter Seedless Smaller due to competition 10. Carbohydrates produced in leaves are mainly transported in the form of __________________ during fruit development Sucrose Glucose Starch Fructose Loading … Question 1 of 10
