Scientist paudhe ka ek chhota, saaf tukda lete hain aur usse khaas botal mein khaas khaane ke saath badhate hain — isse woh ek tukde se hazaaron nayi copy bana lete hain. Ise 'tissue culture' kehte hain.
Har naya paudha bilkul pehle jaisa hi hota hai — same size, same swaad, same taakat — kyunki woh usi tukde ki copy hai.
Kyun zaroori hai? Kyunki isse kisan ko bimari-free, ek jaise achhe paudhe milte hain, aur woh bhi bahut jaldi, bahut zyada sankhya mein.
Yeh sab bahut saaf jagah mein hota hai, taaki koi bimari wale germs paudhe ke tukde ke paas na aayein.
