Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Determining the exact harvest maturity of watermelon (Citrullus lanatus) is vital as it does not ripen further after being detached from the vine (non-climacteric).
Step 2: Detailed Explanation:
The standard maturity and ripening indices for watermelon are:
- The drying or withering of the tendril at the point of fruit attachment.
- The ground spot (where the fruit rests on the soil) turning from white to creamy pale yellow.
- A deep, dull-thud sound when thumped, rather than a metallic, ringing sound.
A change in overall fruit shape is highly variable and depends on environmental factors, and is therefore not a reliable indicator of ripening.
Step 3: Final Answer:
Hence, changing in fruit shape is NOT a true indicator of the fruit ripening stage of watermelon.
