Out breeding device found is Gloriosa

Options

A. heterostyly
B. herkogamy
C. dichogamy
D. Dicliny

Answer

### Step-by-Step Solution:

1. **Understanding Gloriosa Superba**:
- Gloriosa Superba is a flowering plant that has both male (anthers) and female (stigma) reproductive structures in the same flower, making it a bisexual flower.

2. **Pollination Mechanism**:
- In Gloriosa Superba, the pollen grains produced by the anthers do not reach the stigma. This is crucial because if pollen does not reach the stigma, self-pollination cannot occur.

3. **Anther Positioning**:
- The anthers are positioned outwardly and at a distance from the stigma. This spatial arrangement prevents the pollen from falling directly onto the stigma, thereby inhibiting self-pollination.

4. **Floral Barrier**:
- The separation between the anthers and stigma creates a floral barrier. This mechanism is known as **Hercogamy**, which is a strategy to promote cross-pollination by preventing self-fertilization.

5. **Differentiating Other Mechanisms**:
- **Heterostyly**: This involves different lengths of styles in different plants to prevent self-fertilization, which does not apply to Gloriosa.
- **Dichogamy**: This refers to the maturation of anthers and stigmas at different times within the same flower, which also does not apply to Gloriosa.

6. **Conclusion**:
- The outbreeding device found in Gloriosa Superba is **Hercogamy**, as it effectively prevents self-pollination by spatially separating the anthers from the stigma.
