MCQ (Single Correct) +4 −1

Which of the following is NOT a true indicator of fruit ripening stage of watermelon?

निम्नलिखित में से कौन-सा तरबूज (Watermelon) के फल पकने/तुड़ाई परिपक्वता का सही सूचक नहीं है?

Withering of the tendril near the place of fruit attachment फल जुड़ने वाले स्थान के पास वाले प्रतान का सूखना Change of ground spot colour of the fruit भूमि संपर्क धब्बे के रंग में परिवर्तन (सफेद से हल्का पीला) Dull-thud sound on thumping the fruit फल को थपथपाने पर भारी/गहरी आवाज आना Changing in fruit shape फल के आकार में परिवर्तन होना

Statement 4 is NOT a valid indicator (Hence the correct answer): Watermelon maintains its fixed varietal fruit shape (round, oval, or oblong) from the late cell division phase through final development; change in shape is not a recognized maturity index.
Authentic maturity indices in watermelon:

  1. Withering and drying of the tendril at the node where the fruit is borne.
  2. Ground spot (belly spot resting on soil) transitions from white/green to creamy light yellow.
  3. Tapping/thumping the fruit with knuckles gives a heavy, dull-muffled thud (immature melons give a sharp metallic ringing sound).

कथन 4 सही सूचक नहीं है (अतः सही उत्तर है): फल का आकार (fruit shape) किस्म के अनुसार प्रारंभिक अवस्था में ही निर्धारित हो जाता है और पकने पर आकार में कोई विशिष्ट बदलाव नहीं होता।
तरबूज की परिपक्वता के वास्तविक लक्षण:

  1. फल से जुड़े नोड पर स्थित प्रतान (tendril) का सूखकर भूरा होना।
  2. भूमि से लगे धब्बे (ground spot) का सफेद/हरे से मटमैला पीला होना।
  3. उंगली से थपथपाने पर भारी व गहरी (dull thud) ध्वनि का आना (कच्चे फल में तीखी धातु जैसी आवाज आती है)।
