Polyploidy in plants is usually induced using
WebIntroduction: Colchicine is a toxic chemical that is often used to induce polyploidy in plants. Basically, the colchicine prevents the microtubule formation during cell division, thus the chromosomes do not pull apart like they normally do. The end result is a cell that now has double the number of chromosomes that it would normally have. Web2. Production of Polyploid Plants. Polyploid plants (polysomic polyploids, true, and segmental amphidiploids) can be produced using various chemicals, such as colchicine, amiprophos-methyl, trifluralin or oryzalin; or physical methods such as temperature shock and protoplast fusion [].The most common chemical is colchicine obtained from …
