Question:
Identify which of the following is a day neutral plant:
Identify which of the following is a day neutral plant:
Show Hint
Day-neutral plants depend on age or temperature, not photoperiod.
Updated On: Jun 20, 2026
- Glycine max
- Spinacea oleracea
- Lycopersicon esculentum
- Chrysanthemum
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding photoperiodism.
Plants are classified based on their response to day length into short-day, long-day, and day-neutral plants.
Step 2: Definition of day-neutral plants.
Day-neutral plants flower regardless of day length; their flowering is not dependent on photoperiod.
Step 3: Evaluating Glycine max.
Glycine max (soybean) is a short-day plant, so it is not day-neutral.
Step 4: Evaluating Spinacea oleracea.
Spinach is generally a long-day plant, not day-neutral.
Step 5: Evaluating Chrysanthemum.
Chrysanthemum is a short-day plant.
Step 6: Identifying correct option.
Lycopersicon esculentum (tomato) is a classic day-neutral plant, flowering independent of day length.
