Name the hormones that substitute the light requirement in short-day plant.

Explanation

**Step-by-Step Solution:**

1. **Understanding Short-Day Plants**: Short-day plants are those that require longer periods of darkness (more than 12 hours) to initiate flowering. They typically bloom when the days are shorter, such as in late summer or fall.

2. **Role of Light in Flowering**: In general, flowering in plants is influenced by the duration of light and darkness. Short-day plants need a specific light-dark cycle to trigger their flowering process.

3. **Hormonal Substitution**: When natural light conditions do not meet the requirements for flowering in short-day plants, certain hormones can substitute for light.
