Tissue culture: ek chhote tukde se paudhon ki fauj
Kisan ko ek saath hazaaron ek-jaise, healthy kele ke paudhe kaise milte hain?
Socho pehle… phir dekho jawab
Scientist paudhe ka ek bahut chhota, saaf tukda lete hain aur usse khaas botal mein, khaas khaane (nutrients) ke saath badhate hain — yeh 'tissue culture' ya 'micropropagation' kehlata hai.
Process: pehle paudhe ka chhota tukda saaf (sterilise) kiya jaata hai, taaki koi germ na ho. Phir usse ek khaas jelly jaise khaane wale gilaas mein rakha jaata hai, jahan woh dheere-dheere naya paudha banata hai.
Cause-effect: kyunki tukda usi paudhe se aata hai, naya paudha bhi bilkul waisa hi hota hai — same quality, same bimari-resistance. Isliye kisano ko fikar nahi rehta ki paudha kaisa niklega.
Fayda: ek hi accha paudha chuno, aur usse hazaaron copy bana lo — bina bade paudhe ke, aur bahut jaldi.
Ghar pe try karo
Money-plant ya pudina ki daali paani ke gilaas mein rakho. 10 din tak roz observe karke jaden ki lambai naapo aur graph banao.
Wow!
Ek healthy kele ke paudhe se scientist ek saal mein hazaaron nayi copy bana sakte hain!
Mummy-Papa ke liye
Aaj bachche ke saath daali ke jaden ki lambai 10 din naapiye aur graph banwaiye.
3 sawaal
- Tissue culture mein sabse pehle kya kiya jaata hai?
Jawab dekho
Chhota tukda saaf (sterilise) kiya jaata hai. Sabse pehle chhota tukda saaf kiya jaata hai, taaki germ na ho.
- Naya paudha kaisa hota hai?
Jawab dekho
Bilkul waisa hi jaise purana. Naya paudha usi tukde se aata hai, isliye waisa hi hota hai.
- Is tarike se kisano ko kya fayda hota hai?
Jawab dekho
Bimari-free, ek jaise paudhe jaldi milte hain. Isse kisano ko jaldi, ek jaise aur bimari-free paudhe milte hain.
