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: Definition:
The prompt requires classifying a strawberry plant based on its flowering photoperiodic response. Photoperiodism describes how organisms react to day or night length.

Step 2: Breakdown:
Plants are categorized into three groups by photoperiodic response:
\[\begin{array}{rl} \bullet & \text{Short-day plants (SDP): Flower when days are shorter than a critical length (long-night plants). } \\ \bullet & \text{Long-day plants (LDP): Flower when days are longer than a critical length (short-night plants). } \\ \bullet & \text{Day-neutral plants (DNP): Flower regardless of day length. } \\ \end{array}\]Most common strawberry cultivars (Fragaria × ananassa) are short-day plants. They form flower buds during the short days of fall and winter, which then produce fruit in the spring. Although long-day and day-neutral varieties exist, strawberries are typically classified as short-day plants.

Step 3: Conclusion:
Strawberry plants are generally short-day plants.
