Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Brown core of apple develops in the fruit at the time of fruit set
Reason (R) : Brown core is a low storage problem developing in fruits at -1$^\circ$C to 2$^\circ$C
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
• B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A).
• C. (A) is correct but (R) is not correct.
• D. (A) is not correct but (R) is correct.

Hint:

Core browning/brown core is a post-harvest chilling disorder, not a developmental pre-harvest field disorder. It develops during cold storage at \(-1^\circ\text{C}\) to \(2^\circ\text{C}\).

Answer 1

The Correct Option is D

Let's analyze the given Assertion and Reason statements and determine the correct relationship between them.

1. Assertion (A): Brown core of apple develops in the fruit at the time of fruit set.
   • The assertion implies that the browning of the core in apples happens during the initial stages of fruit set, which is when the fruit begins to form after flowering.
   • However, this statement is incorrect. Typically, the browning or "brown core" of apples is a storage disorder that occurs after harvesting, not during the initial fruit set.
   • Brown core in apples usually develops due to storage conditions causing internal breakdown, rather than during early development.
2. Reason (R): Brown core is a low storage problem developing in fruits at -1°C to 2°C.
   • This statement is correct. Brown core is indeed a storage-related issue, often caused by suboptimal storage temperatures.
   • Apples stored at temperatures ranging from -1°C to 2°C may develop brown core due to chilling injury or other storage-related physiological breakdowns.
3. Evaluation of the Correct Answer:
   • The Assertion (A) is incorrect because brown core does not develop at the time of fruit set. Instead, it is a storage-related condition.
   • The Reason (R) correctly identifies that brown core is a storage problem occurring at certain temperatures.
   • Based on this analysis, the correct answer is: (A) is not correct but (R) is correct.
