The greatest disadvantage of seed propagation in perennial fruit crops is _________________________ Genetic variability and prolonged juvenile phase Poor nutrient uptake Poor root development Low germination 4. Select correctly matched fruit crop–botanical family pair Banana— Rutaceae Litchi — Sapindaceae Cashew — Myrtaceae Guava — Anacardiaceae 5. Naphthalene acetic acid (NAA) belongs to which class of plant growth regulators? Synthetic Gibberellins Growth retardants Synthetic auxins Synthetic Cytokinins 6. In table grape production, main purpose of applying gibberellic acid (GA3) shortly after berry set is __________________ To increase berry size and improve cluster looseness To promote berry thinning by causing flower drop To stimulate earlier coloration and ripening To induce uniform leaf fall before harvest 7. Select correctly matched fruit crop–scientific name pair Oil palm — Borassus flabellifer Arecanut — Fragaria chiloensis Coconut — Cocos nucifera Cinnamon — Elaeis guineensis 8. The greatest advantage of vegetative propagation is that it produces ______________________________ Hybrid seedlings True-to-type plants Polyploid plants Disease-resistant plants 9. Why are most commercial seedless bananas described as triploid rather than diploid or tetraploid? They have two sets of chromosomes, allowing perfect pairing in meiosis They have four sets of chromosomes, which always pair correctly in meiosis They have only one set of chromosomes, so they skip meiosis entirely They have three sets of chromosomes, disrupting normal pairing in meiosis 10.
