Flower Sex Expression
  • Flower Types
  • Staminate Flower Male Flower
  • Pistillate Flower Female Flower
  • Hermaphroditic Flower (Perfect flower)
  • Male and female parts together in a single
    flower

27
Flower Sex Expression
  • Plant Types
  • Monoecious - Plants carrying both male and
    female flowers
  • the same plant (cucumber, corn)
  • Dioecious - Species in which separate male
    (staminate) and
  • female (pistillate) plants exist
  • (Date palm, papaya, spinach, hemp, ginkgo)
  • Andromonoecious - Plants carrying both male and
    perfect flowers the same plant
    (muskmelon)
  • Gynomoecious - Plants carrying both female and
    hermaphroditic
  • flowers on the same plant (some cucurbits)
  • Trimonoecious - Plants carrying make, female,
    and hermaphroditic flowers on the same
    plant (some cucurbits)
