The pear fruit for fresh consumption/ market can be stored at:
The pear fruit for fresh consumption/ market can be stored at:
Show Hint
Unlike apples, pears do not ripen on the tree.
They must be harvested when firm and mature, cold-stored, and then transferred to warmer temperatures (\( 15^\circ\text{C} \) to \( 20^\circ\text{C} \)) to ripen properly.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Cold storage of pear (Pyrus communis) requires precise temperature and humidity management to prevent premature ripening, physiological disorders, and moisture loss.
Step 2: Detailed Explanation:
Pears are climacteric fruits that are harvested when mature but still firm.
They are highly sensitive to storage temperatures. The optimum storage temperature for most pear cultivars is very close to their freezing point.
The ideal range is between \( -0.5^\circ\text{C} \) and \( -1.1^\circ\text{C} \) (written as \( 0.50^\circ\text{C} \) to \( -1.1^\circ\text{C} \) in standard publications, where \( 0.50^\circ\text{C} \) represents the upper tolerable limit).
Maintaining this low temperature slows down the fruit's respiration rate, ethylene production, and overall ripening process.
A high relative humidity (RH) of 90% to 95% is crucial. This high humidity prevents moisture loss from the skin, which would otherwise cause the fruit to shrivel and lose weight.
Under these conditions, pears can be stored safely for up to 6 months while maintaining excellent quality.
Temperatures of \( -4^\circ\text{C} \) (C) are too cold and would cause freezing injury, while warmer temperatures like 4-\( 5^\circ\text{C} \) (B) or 8-\( 10^\circ\text{C} \) (D) would cause rapid ripening and decay within a few weeks.
Thus, option (A) is the correct storage recommendation.
Step 3: Final Answer:
The optimum storage condition for fresh pears is \( 0.50^\circ\text{C} \) to \( -1.1^\circ\text{C} \) with 90-95% RH for 6 months.
