Answer:
The answer is Short night.
Step-by-step explanation:
Oat is an example of a short night plant. Short night plants are also called long day plants, their flowering is induced by long days. Their plants flower when they are exposed to day length longer than the critical minimum requirement (i.e the days are longer than the critical day length). They usually flower in the spring or early summer. Their flowering can also be induced if the plants are exposed to short light period with still shorter dark period. Some other examples include; Barley, lettuce, wheat.
