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 each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Gibberellins**: Gibberellins (GA) are plant hormones that play a key role in regulating various developmental processes in plants, including growth, flowering, and seed germination.

2. **Evaluating the Functions of Gibberellins**:
- **Bolting**: Gibberellins promote bolting (the rapid elongation of the flowering stem) in plants like beet and cabbage. This statement is correct.
- **Delaying Maturity in Conifers**: The statement mentions that spraying juvenile conifers with gibberellins delays the maturity period by delaying seed production. Gibberellins actually promote growth and can lead to earlier maturity in some cases. Thus, this statement is incorrect.
- **Elongation of Apples**: Gibberellins are known to cause elongation in fruits like apples and improve their shape. This statement is correct.
- **Speeding Up Malting Processes**: Gibberellins are used in the malting process in brewing industries to promote germination and growth of the grains. This statement is also correct.

3. **Identifying the Incorrect Statement**: From the evaluation, the statement that gibberellins delay the maturity period and seed production in juvenile conifers is incorrect. Gibberellins generally promote growth and can lead to earlier maturity.

4. **Conclusion**: The incorrect statement regarding the function of gibberellins is the one that claims they delay maturity and seed production in juvenile conifers.

### Final Answer:
The incorrect statement regarding the function of gibberellins is: "Spraying juvenile conifers with GA delays the maturity period by delaying their seed production."
