Fig.: No. open flowers on greenhouse plants: 
All open flowers pollinated daily
Slide 18 of 21
  
  Notes:

    I found the same pattern in the greenhouse where I pollinated all of the
    flowers that bloomed each day on 12 plants, and summed the number of flowers
    in bloom in this small population. Here the plants reach their peak bloom
    very rapidly, and then bloom decreases over time.
