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