Light break reaction means

Options

A. influence of short periods of dark in the light period
B. influence of short periods of light in the dark periods
C. influence of `GA_3` on light periods
D. production of some inhibitors during light periods

Answer

**Step-by-Step Text Solution:**

1. **Understanding Light Break Reaction:**
- The light break reaction refers to the phenomenon where a short exposure to light during the dark period affects the flowering and growth of certain plants, particularly short-day plants.

2. **Night Interruption Experiments:**
- In these experiments, short-day plants are exposed to a brief flash of light during their dark period. This interruption can prevent the plant from reaching the critical dark period necessary for flowering.

3. **Effect of Light Exposure:**
- The brief exposure to light essentially disrupts the plant's perception of the dark period, which is crucial for the flowering process in short-day plants. This is known as the light break effect.

4. **Wavelength Absorption:**
- The leaves of the plants absorb specific wavelengths of light during this brief exposure. This absorption triggers physiological responses in the plant that can alter its growth and flowering patterns.

5. **Conclusion:**
- Therefore, the correct interpretation of the light break reaction is the influence of short periods of light during the dark period, which can affect plant development.

**Final Answer:**
The light break reaction means the influence of short periods of light in the dark period.
