Question

Would a defoliated plant respond to photoperiodic cycle ?

• A. No
• B. Any condition is possible
• C. Yes
• D. Can't say

Answer 1

The correct option is A No

Photoperiodism

Photoperiodism is defined as the response of different plants as per the relative length of the day and night.

Photoperiodism in defoliated plants

Since leaves are the main sites of reception of photoperiod (sunlight), the changes in plants is response to photoperiodism are mediated by the leaves.
In defoliated plants, the leaves are absent and hence photoperiodic cycle will not occur in them. The site of perception of light/dark duration is absent.

Final answer
(B) No
