The process of removing stamen from flora buds during hybridisation experiments is

Options

A. Capping
B. Selfing
C. Emasculation
D. Crossing

Answer

To answer the question regarding the process of removing stamen from floral buds during hybridization experiments, we can analyze the options provided:

1. **Capping**: This term refers to the addition of a methylated guanosine triphosphate at the 5' end of HNRNA. It is not related to the process of hybridization in plants.

2. **Selfing**: This term describes the transfer of pollen grains from the anthers to the stigma of the same flower, which is known as self-pollination. This is not the process of removing stamen.

3. **Emasculation**: This is the correct term for the process of removing the anthers (stamen) from the flowers of the female parent plant. Emasculation is done to prevent self-pollination and to ensure that controlled cross-pollination can occur.

4. **Crossing**: This term refers to the transfer of pollen grains from the anthers of one flower to the stigma of another flower of the same species. While it is related to hybridization, it does not involve the removal of stamen.

Based on the analysis of the options, the correct answer is **Emasculation**.

### Step-by-Step Solution:
1. **Identify the process**: We need to determine what the process of removing stamen from floral buds is called.
2. **Analyze the options**: Review each option provided (Capping, Selfing, Emasculation, Crossing) to understand their definitions.
3. **Eliminate incorrect options**:
- Capping does not relate to floral anatomy.
- Selfing involves the same flower and does not involve removal of stamen.
- Crossing involves pollen transfer but does not involve removing stamen.
4. **Select the correct option**: Emasculation is defined as the removal of anthers from the flower, making it the correct answer for the process described in the question.
