प्रश्न
Would a defoliated plant respond to photoperiodic cycle? Why?
Advertisements
उत्तर
- No, as only the leaves get photoperiodic stimuli, a defoliated plant would not react to the photoperiodic cycle.
- For this purpose, even a single leaf, or a portion of one, is sufficient. In order for the hormone responsible for flowering to be produced, leaves under inductive photoperiod must be present in order for the photoperiodic cycle to be perceived.
