The correct answer is: short day plants
Every plant requires a certain amount of light and darkness to grow and this aspect is known as photoperiodism. The plants which require only a short period of darkness to flower are known as long-day plants whereas the plants which require a short day length and the long period of darkness without any interruption by light are known as short-day plants.
