Which of the following factors influence the process of flowering?

  1. Acidity of soil
  2. Water in the soil
  3. Amount of green pigment
  4. Photoperiod
Correct Answer: Option(d)
Solution: In photoperiod, a duration of day length suitable for flowering, plants secrete Florigen. Florigen induces flowering in angiospermic plants. Florigen is the hypothesized hormone-like molecule responsible for controlling and triggering flowering in plants. It is produced in the leaves and acts in the shoot apical meristem of buds and growing tips. It is known to be graft-transmissible, and even functions between species.
So, the correct answer is 'Photoperiod'
