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