  • 2. 
    Both geitonogamy and autogamy are prevented in

  • Cucumber
  • Papaya
  • Mazia
  • Castor

  • 3. 
    The pollen tube releases the two male gametes into the

  • the cytoplasm of antipodal cells
  • one male gamete in cytoplasm of synergids and other in cytoplasm of central cell
  • both in cytoplasm of central cell
  • both in cytoplasm of synergids

  • 4. 
    Who first used artificial hybridization in fruit crops?

  • Karpocho
  • Knight
  • Jones
  • Mendel

  • 5. 
    This will lose its economic value if fruits are produced through parthenocarpy

  • Banana
  • Citrus
  • Pomegarante
  • Grape

  • 6. 
    After reaching the ovary, pollen tube does not display this of the following events

  • may enter the ovule through chalaza
  • enters one of the synergids through filiform apparatus
  • enters the ovule through the micropyle
  • chemotactic movement of pollen tube towards synergid

  • 7. 
    This statement is incorrect

  • the seed dormancy is the internal or innate inhibition of generation of normal or viable seeds
  • embryo in the dormant seeds show higher rate of general metabolic rate
  • because fo dormancy seeds remain viable for long durations and can be stored
  • as the seeds mature, its water content is reduced and seeds become relatively dry

  • 8. 
    When dioecious plants are considered for artificial hybridization, this step would not be relevant

  • collection of pollen
  • bagging of female flower
  • dusting of pollen on stigma
  • emasculation

  • 9. 
    Aleurone layer participates in

  • enzyme synthesis
  • transfer of food to cotyledons
  • is also known as scutellum
  • protection of delicate embryo

  • 10. 
    The external conditions required for seed germination are

  • light, moisture and appropriate temperature
  • oxygen, carbon dioxide and appropriate temperature
  • oxygen, light and appropriate temperature
  • oxygen, moisture and suitable temperature
