Question

Strawberry is a typically

• A. Short day plant
• B. Long day plant
• C. Day neutral plant
• D. CAM Plant

Hint:

For exams, it's good to know the photoperiodic classification of a few key crops. For instance, Rice (many varieties) and Soybean are short-day plants. Wheat and Spinach are long-day plants. Maize and Tomato are generally day-neutral plants.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
The question asks to classify the strawberry plant based on its photoperiodic response for flowering. Photoperiodism is the physiological reaction of organisms to the length of day or night.

Step 2: Detailed Explanation:
Plants are classified into three main groups based on their photoperiodic response:
\[\begin{array}{rl} \bullet & \text{Short-day plants (SDP): These plants flower when the day length is less than a certain critical duration. They are technically "long-night" plants. } \\ \bullet & \text{Long-day plants (LDP): These plants flower when the day length exceeds a certain critical duration. They are technically "short-night" plants. } \\ \bullet & \text{Day-neutral plants (DNP): These plants flower irrespective of the day length. } \\ \end{array}\] Most traditional and commercially important strawberry cultivars (Fragaria × ananassa) are short-day plants. They initiate flower buds during the short days of autumn and winter, which then develop and produce fruit in the spring. While long-day and day-neutral varieties have been developed, the typical classification for strawberry is as a short-day plant.

Step 3: Final Answer:
Strawberry is typically a short-day plant.
