Explanation:
Detailed explanation-1: -Leaves are considered to be the site of perception for photoperiodic stimulation. Now, it has been observed that a lot of plants need periodic exposure to light to induce flowering. It is the shoot apices of plants that modify themselves to flowering apices just before flowering.
Detailed explanation-2: -A photoperiod of 9 to 12 hr is most effec-tive for floral induction in the rice cultivar used in the present study, and complete fail-ure of flowering occurs under photoperiods of 2 hr or less as well as 15 hr or more.
Detailed explanation-3: -Reason: The site of perception of light or dark duration are the shoot apices of plants.
