Marketable yield differs from total yield because it primarily excludes __________________________ Fruits from young trees Immature fruits Damaged, diseased, or undersized fruits Export-quality fruits 2. The principal objective of intercropping in young orchards is to _____________________________ Utilize available land efficiently before full canopy development Reduce tree vigor Delay flowering Reduce fruit size 3. ______________________ exhibits stenospermocarpy rather than true parthenocarpy Seedless grape Pineapple Fig Banana 4. In banana production, plant growth regulator _____________ is commonly used post-harvest to delay ripening during transport and storage 1-methylcyclopropene Abscisic acid Ethylene gas Gibberellic acid 5. Fruit thinning improves fruit size mainly because the remaining fruits receive more _________________ Chlorophyll Nitrogen Photosynthates, water, and nutrients Hormones 6. In plants, abscisic acid (ABA) plays an important role in_______________________ Stress tolerance Increasing vegetative growth Delaying abscission Breaking seed dormancy 7. The primary economic advantage of fruit grading is to ______________________ Increase seed germination Increase fruit respiration Reduce flowering variation Standardize quality for marketing 8. In citrus production, __________________ is applied to reduce fruit drop and improve fruit retention during the early stages of development 2,4-D (2,4-dichlorophenoxyacetic acid) Ethephon Gibberellic acid Abscisic acid 9. Which orchard floor management practice primarily aims to conserve soil moisture and suppress weeds? Deep plowing Girdling Summer pruning Mulching 10. 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 Loading … Question 1 of 10
