The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Physiological disorders in citrus rinds often occur during post-harvest storage due to temperature, relative humidity, or cultivar sensitivity.
Step 2: Detailed Explanation:
Let us analyze the statements regarding superficial rind pitting:
- Statement (A) is correct: It is a physiological disorder known as "Nox" that primarily damages 'Shamouti' sweet orange, causing sunken necrotic patches on the flavedo.
- Statement (B) is correct: Symptoms are post-harvest, typically appearing and developing 3 to 5 weeks after the fruit is harvested and stored.
- Statement (D) is correct: It is a low-temperature chilling injury; storing fruit at $5~^\circ\text{C}$ significantly increases the incidence and severity of the pitting compared to warmer storage temperatures.
- Statement (C) is incorrect: Ethylene degreening or exposure does not cause or increase this specific low-temperature-related physiological pitting.
Hence, statements (A), (B), and (D) are correct.
Step 3: Final Answer:
The correct option is (A).
