Scientists discover the hidden 'muscles' trees use to straighten themselves

سائنسدانوں نے درختوں کے چھپے ہوئے 'پٹھے' دریافت کر لیے جن سے وہ خود کو سیدھا کرتے ہیں

वैज्ञानिकों ने पेड़ों की छिपी हुई 'मांसपेशियाँ' खोजीं जिनसे वे खुद को सीधा करते हैं

Scientists discover the hidden 'muscles' trees use to straighten themselves

Key points

اہم نکات

मुख्य बातें

  • Scientists have discovered how trees straighten themselves using a hidden muscle-like system.
  • Researchers at INRAE found that young poplar trees sense their own shape, a sense called proprioception, and grow a special tissue called tension wood that pulls like a contracting muscle.
  • When curved trees were placed in a rotating device that removed gravity and light cues, tension wood stopped forming on one side and formed on the opposite side instead, slowly pulling the stems straight again.
  • سائنسدانوں نے دریافت کر لیا ہے کہ درخت خود کو سیدھا کرنے کے لیے چھپے ہوئے پٹھوں جیسے نظام کا استعمال کرتے ہیں۔ انریے کے محققین نے پایا کہ نوجوان پاپلر درخت اپنی شکل کو محسوس کرتے ہیں، جسے پروپریوسیپشن کہتے ہیں، اور ایک خاص ٹشو بناتے ہیں جسے ٹینشن ووڈ کہتے ہیں جو سکڑتے ہوئے پٹھے کی طرح کھینچتا ہے۔ جب ٹیڑھے درختوں کو ایک گھومنے والے آلے میں رکھا گیا جس نے کشش ثقل اور روشنی کے اشارے ختم کر دیے، تو ایک طرف ٹینشن ووڈ بننا رک گیا اور مخالف سمت میں بننے لگا، جس سے تنے آہستہ آہستہ سیدھے ہو گئے۔ ٹیم کا کہنا ہے کہ یہ مخالف پٹھوں کا نظام جنگلات کے لیے مددگار ہو سکتا ہے اور اپنی شکل خود درست کرنے والے مواد کی ترغیب بن سکتا ہے۔
  • वैज्ञानिकों ने खोज लिया है कि पेड़ खुद को सीधा करने के लिए छिपी हुई मांसपेशियों जैसी प्रणाली का इस्तेमाल करते हैं। आईएनआरएई के शोधकर्ताओं ने पाया कि युवा पॉपलर पेड़ अपने आकार को महसूस करते हैं, जिसे प्रोप्रियोसेप्शन कहते हैं, और एक विशेष ऊतक बनाते हैं जिसे टेंशन वुड कहते हैं जो सिकुड़ती हुई मांसपेशी की तरह खींचता है। जब टेढ़े पेड़ों को एक घूमने वाले उपकरण में रखा गया जिसने गुरुत्वाकर्षण और प्रकाश के संकेत हटा दिए, तो एक तरफ टेंशन वुड बनना रुक गया और विपरीत तरफ बनने लगा, जिससे तने धीरे-धीरे सीधे हो गए। टीम का कहना है कि यह विरोधी-मांसपेशी प्रणाली वानिकी के लिए मददगार हो सकती है और अपना आकार खुद ठीक करने वाली सामग्रियों की प्रेरणा बन सकती है।

Scientists have discovered how trees straighten themselves using a hidden muscle-like system. Researchers at INRAE found that young poplar trees sense their own shape, a sense called proprioception, and grow a special tissue called tension wood that pulls like a contracting muscle. When curved trees were placed in a rotating device that removed gravity and light cues, tension wood stopped forming on one side and formed on the opposite side instead, slowly pulling the stems straight again. The team says this opposing-muscle system could help forestry and inspire materials that adjust their own shape.
