FW. Went is associated with

Options

A. Isolation of auxins from the coleptiles tips of oat seedlings
B. Isolation of auxins form the coleoptiles tips of canary grass seedling
C. Isolution of Gibberellins form Gibberalla fuzikuroi
D. Isolation of auxins form the coleoptiles of both canary grass and oat seedlings

Answer

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

1. **Identify the Scientist**: The question asks about FW Went, who is a significant figure in plant physiology.

2. **Understand the Contribution**: FW Went is known for isolating a plant hormone called auxin.

3. **Source of Isolation**: He isolated auxin from the choleoptile tip of oat seedlings. The choleoptile is the part of the plant that protects the emerging shoot.

4. **Function of Auxin**: Auxin is essential for various plant growth processes, including apical dominance, which is the phenomenon where the main stem grows more vigorously than the side stems.

5. **Clarification of Terms**: The choleoptile is the upper part of the seedling that develops into the shoot apex, while the choleoriza is the part that develops into the root apex.

6. **Conclusion**: The correct association for FW Went is the isolation of auxin from the choleoptile tip of oat seedlings.

**Final Answer**: FW Went is associated with the isolation of auxin from the choleoptile tip of oat seedlings.
