The primary economic advantage of fruit grading is to ______________________ Standardize quality for marketing Increase fruit respiration Reduce flowering variation Increase seed germination 2. ______________________ exhibits stenospermocarpy rather than true parthenocarpy Seedless grape Pineapple Banana Fig 3. Fruit thinning improves fruit size mainly because the remaining fruits receive more _________________ Nitrogen Hormones Chlorophyll Photosynthates, water, and nutrients 4. The principal objective of intercropping in young orchards is to _____________________________ Reduce fruit size Reduce tree vigor Utilize available land efficiently before full canopy development Delay flowering 5. What role does parthenocarpy play in the formation of seedless banana fruits? Parthenocarpy stops flower formation entirely, preventing any fruit or seed development in the plant Parthenocarpy allows fruits to develop without fertilization Parthenocarpy ensures that meiosis does not occur in the ovules Parthenocarpy causes all ovules to be fertilized twice 6. In citrus production, __________________ is applied to reduce fruit drop and improve fruit retention during the early stages of development Abscisic acid Gibberellic acid 2,4-D (2,4-dichlorophenoxyacetic acid) Ethephon 7. In plants, abscisic acid (ABA) plays an important role in_______________________ Breaking seed dormancy Increasing vegetative growth Delaying abscission Stress tolerance 8. Marketable yield differs from total yield because it primarily excludes __________________________ Export-quality fruits Damaged, diseased, or undersized fruits Immature fruits Fruits from young trees 9. Which orchard floor management practice primarily aims to conserve soil moisture and suppress weeds? Mulching Girdling Summer pruning Deep plowing 10.
