Which one hastens flowering in plants

Options

A. Stratification
B. Scarification
C. Vernalisation
D. Water deficit.

Answer

To answer the question "Which one hastens flowering in plants?", let's analyze the provided options step by step.

### Step 1: Understanding Stratification
- **Definition**: Stratification refers to the formation of layers in plants, particularly in relation to growth processes.
- **Relation to Flowering**: Stratification involves the development of apical and intercalary meristems, leading to primary and secondary growth. However, it does not directly influence flowering.
- **Conclusion**: Stratification does not hasten flowering. **(Wrong option)**

### Step 2: Understanding Scarification
- **Definition**: Scarification is the process of breaking or softening the seed coat to promote germination.
- **Relation to Flowering**: While scarification aids in the germination of seeds, it does not have a direct effect on hastening flowering.
- **Conclusion**: Scarification does not hasten flowering. **(Wrong option)**

### Step 3: Understanding Vernalization
- **Definition**: Vernalization is the process of exposing seeds to prolonged cold temperatures to break dormancy.
- **Relation to Flowering**: This cold treatment induces the flowering process in many plants, making it a crucial factor in hastening flowering.
- **Conclusion**: Vernalization hastens flowering in plants. **(Correct option)**

### Step 4: Understanding Water Deficit
- **Definition**: Water deficit refers to a lack of sufficient water, which can stress plants.
- **Relation to Flowering**: A deficiency of water can hinder photosynthesis and overall plant health, potentially leading to plant death, rather than promoting flowering.
- **Conclusion**: Water deficit does not hasten flowering. **(Wrong option)**

### Final Answer
The correct answer is **vernalization**, as it is the process that hastens flowering in plants.
