Question

Which is the short day plant from the following?

• A. Cotton
• B. Rice
• C. Sugarcane
• D. All of the above

Answer 1

The correct option is D All of the above

Short-day plants flower when their day lengths are less than their critical photoperiods. They are unable to flower during long days with extreme amounts of sunlight or when exposed to a great deal of artificial light. These plants require regular periods of darkness to mature and flower, and they typically begin their growth during the summer months but do not flower until fall, when the days are getting shorter. There are many varieties of short-day plants. A lot of them are very important to agriculture and society, e.g., cotton, rice, and sugar cane.
