Girdling Summer pruning Mulching Deep plowing 2. In plants, abscisic acid (ABA) plays an important role in_______________________ Stress tolerance Breaking seed dormancy Increasing vegetative growth Delaying abscission 3. The principal objective of intercropping in young orchards is to _____________________________ Utilize available land efficiently before full canopy development Delay flowering Reduce tree vigor Reduce fruit size 4. What role does parthenocarpy play in the formation of seedless banana fruits? Parthenocarpy ensures that meiosis does not occur in the ovules Parthenocarpy causes all ovules to be fertilized twice Parthenocarpy stops flower formation entirely, preventing any fruit or seed development in the plant Parthenocarpy allows fruits to develop without fertilization 5. In banana production, plant growth regulator _____________ is commonly used post-harvest to delay ripening during transport and storage Gibberellic acid Abscisic acid Ethylene gas 1-methylcyclopropene 6. ______________________ exhibits stenospermocarpy rather than true parthenocarpy Fig Seedless grape Banana Pineapple 7. Fruit thinning improves fruit size mainly because the remaining fruits receive more _________________ Nitrogen Chlorophyll Hormones Photosynthates, water, and nutrients 8. In citrus production, __________________ is applied to reduce fruit drop and improve fruit retention during the early stages of development Ethephon 2,4-D (2,4-dichlorophenoxyacetic acid) Abscisic acid Gibberellic acid 9. Marketable yield differs from total yield because it primarily excludes __________________________ Fruits from young trees Damaged, diseased, or undersized fruits Export-quality fruits Immature fruits 10. The primary economic advantage of fruit grading is to ______________________ Increase fruit respiration Reduce flowering variation Increase seed germination Standardize quality for marketing Loading … Question 1 of 10
