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