Answer 1

Answer:

option b

Explanation:

Answer 2

The correct answer is  B) LDP.

Explanation:

Plants need specific day time and dark period for developing flower.

• SDP or Short Day Plant- This kind of plants require less day time for developing flower(Less then Critical day length).

• LDP or Long Day Plant- This kind of plants require more day time for developing flower (Greater then Critical day length).

• SLDP or Short Long Day Plant- During the budding of the flower they need short day time, and then they require long day time.  

• DNP OR Day Neutral Plant- For this kind of plants day length is not leading to any effect on the plant.

So for the above question, the plant needs 5 hours light and 3 hours dark to produce flowers. So this plant is LDP or Long Day Plant.

So, the correct answer is  B) LDP.
