After pollination viability of pollen grains of wheat/ rice is about

Options

A. 30 min
B. 60 min
C. 70 min
D. 90 min

Answer

**Step-by-Step Solution:**

1. **Understand the Concept of Pollination**: Pollination is the transfer of pollen grains from the male part of the flower (anther) to the female part (stigma). In wheat and rice, this process is facilitated by the wind.

2. **Identify the Type of Pollination**: Wheat and rice are classified as wind-pollinated plants. This means they rely on wind to carry pollen grains to the stigma of the flowers.

3. **Importance of Pollen Viability**: The viability of pollen grains is crucial for successful fertilization. If pollen grains are not viable for a sufficient amount of time after pollination, fertilization cannot occur.

4. **Determine the Viability Duration**: According to the information provided, the viability of pollen grains for wheat and rice after pollination is approximately 30 minutes.

5. **Select the Correct Answer**: Given the options provided (30 minutes, 60 minutes, 70 minutes, 90 minutes), the correct answer is 30 minutes, as it reflects the viability duration of pollen grains for these wind-pollinated plants.

**Final Answer**: The viability of pollen grains of wheat/rice after pollination is about **30 minutes**.
