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 are propagated vegetatively using suckers, rhizomes, or tissue culture They produce abundant viable seeds that farmers plant every season 2. Abscisic acid (ABA) is primarily associated with ____________________________ Cell division Root formation Stomatal closure and drought response Fruit thinning 3. Anthesis is the stage at which ______________ The flower opens Fruit matures Seed germinates Pollination is completed 4. Plant growth regulator _________________ is most often used to promote uniform flowering and increase fruit set in mango by breaking bud dormancy Naphthalene acetic acid Ethephon Paclobutrazol Cytokinins 5. Excessive fruit load generally produces fruits that are _________________ Seedless Larger and sweeter Smaller due to competition Resistant to diseases 6. Naphthalene acetic acid (NAA) delays apple fruit drop primarily by ______________________ Increasing respiration Breaking dormancy Preventing abscission layer formation Increasing ethylene production 7. Windbreaks are established in orchards primarily to ____________ Increase pollination Improve rootstock compatibility Reduce wind damage and moisture loss Increase sunlight interception 8. A cultivar is best described as _______________________ A genetically modified plant A naturally occurring wild species A cultivated variety selected for desirable traits A hybrid rootstock 9. Which propagation method maintains varietal purity? Seed propagation Vegetative propagation Mutation breeding Open pollination 10. Carbohydrates produced in leaves are mainly transported in the form of __________________ during fruit development Sucrose Glucose Starch Fructose Loading … Question 1 of 10
