Auxins are known to promote ………...in pineapples.

Options

A. flowering
B. root formation
C. abscission
D. node elongation

Answer

To solve the question "Auxins are known to promote ………...in pineapples," we can follow these steps:

### Step 1: Understand what Auxins are
Auxins are a class of plant hormones that play a crucial role in the growth and development of plants. They are primarily involved in processes such as cell elongation, apical dominance, and the regulation of various growth responses.

**Hint:** Think about the role of hormones in plant growth and development.

### Step 2: Identify the functions of Auxins
Auxins are known for promoting:
- Cell elongation
- Apical dominance (inhibiting lateral bud growth)
- Root formation
- Flowering in certain plants

**Hint:** Consider how auxins influence different parts of the plant and their growth processes.

### Step 3: Relate Auxins to Pineapples
In the context of pineapples, auxins, specifically a synthetic form called naphthalene acetic acid (NAA), are known to promote flowering. This is particularly important in pineapple cultivation as it helps in synchronizing the flowering process.

**Hint:** Focus on the specific effects of auxins in the context of pineapple plants.

### Step 4: Analyze the options
Given the options:
1. Flowering
2. Root formation
3. Abscission
4. Node elongation

From our understanding, auxins promote flowering in pineapples through the action of NAA. The other options do not accurately reflect the primary role of auxins in this specific context.

**Hint:** Eliminate options that do not align with the known effects of auxins on pineapples.

### Step 5: Conclusion
The correct answer is that auxins are known to promote **flowering** in pineapples.

**Final Answer:** Flowering
