Which of the following is incorrect regarding the function of gibberellins ?

Options

A. Bolting in beet , cabbages etc.
B. Spraying juvenile conifers with GA delays the maturity period thereby delaying their seed production.
C. Elongation of apples and improve its shape
D. Used to speed up the malting process in brewing industry.

Answer

To determine which statement regarding the function of gibberellins is incorrect, we will analyze the functions of gibberellins step by step.

### Step 1: Understanding Gibberellins
Gibberellins are plant hormones that play a crucial role in various growth processes. They are known for their ability to promote stem elongation, seed germination, and flowering.

**Hint:** Remember that gibberellins are primarily associated with growth and developmental processes in plants.

### Step 2: Analyzing the Options
1. **Option A:** Bolting in beet and cabbage.
- Gibberellins promote bolting, which is the rapid elongation of the stem in certain plants, particularly in response to environmental cues. This statement is correct.

**Hint:** Bolting is a key process in certain plants that gibberellins influence positively.

2. **Option B:** Spraying juvenile conifers with gibberellic acid delays the maturity period, thereby delaying seed production.
- This statement is incorrect. Spraying juvenile conifers with gibberellins actually promotes early maturation and seed production, not delays it.

**Hint:** Think about the effects of gibberellins on maturation and flowering; they typically accelerate these processes.

3. **Option C:** Elongation of apple and improvement of its shape.
- Gibberellins are known to enhance the elongation of fruits like apples, contributing to their shape and size. This statement is correct.

**Hint:** Gibberellins are often used to improve fruit quality and size.

4. **Option D:** Speeding up the malting process in the brewing industry.
- Gibberellins are indeed used in the malting process to enhance the germination of seeds, which is beneficial in brewing. This statement is correct.

**Hint:** Consider the applications of gibberellins in agriculture and industry, especially in malting.

### Step 3: Conclusion
After analyzing all the options, we find that the incorrect statement regarding the function of gibberellins is **Option B**.

### Final Answer:
**Option B:** Spraying juvenile conifers with gibberellic acid delays the maturity period, thereby delaying seed production.
