Show Hint
Ensure adequate irrigation during the flowering and pod-filling stages of garden peas.
This moisture helps lower the canopy temperature and reduces the risk of blanking.
This moisture helps lower the canopy temperature and reduces the risk of blanking.

- Reduced development of ovules in pods
- Absence of ovules in pods
- Merger of nearby ovules leading to seed absence
- Absence of parchment layers in pods

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Abiotic stresses during critical reproductive phases can lead to physiological disorders in vegetable crops.
In garden peas (*Pisum sativum*), high temperatures and water deficit during flowering impair seed development.
Step 2: Detailed Explanation:
Garden pea is a cool-season crop that is highly sensitive to heat and moisture stress during pollination and fertilization.
"Blanking" is a physiological disorder that occurs under these stress conditions.
Exposure to temperatures above \( 25^\circ\text{C} \) or water deficit during flowering reduces pollen viability and fertilizing capacity.
This results in poor fertilization, leading to the failure or reduced development of ovules inside the pods.
Consequently, the pods develop with empty spaces or contain small, undeveloped seeds.
This condition is defined as the reduced development of ovules in the pods.
This disorder reduces the yield and processing quality of peas.
Therefore, option (A) is the correct description.
Step 3: Final Answer:
Blanking in peas is characterized by the reduced development of ovules in the pods.
