WebColchicine in concentrations ranging from 2 × 10 -4 M. to 6 × 10 -2 M. inhibits spindle formation and thus prevents anaphase. The drug slows down, but does not inhibit, the normal chromatin ... WebThere have also been extensive applications in the breeding of cultivated plants. One of the important events in this field was the discovery (Blakeslee and A. G. Avery, 1937) that doubling of the chromosome set in plants may be induced by the use of colchicine. Winge’s interpretation of polyploidy grew out of a comparison of the

Trifluralin-mediated polyploidization of fenugreek

WebHigh concentrations are toxic for plant cells and usually cause abnormal plant growth or reduced viability, while low concentrations may be ineffective or induce many ... Fu, J.; … WebIn some situations, polyploid crops are preferred because they are sterile. For example, many seedless fruit varieties are seedless as a result of polyploidy. Such crops are propagated using asexual techniques, such as grafting. Polyploidy in crop plants is most commonly induced by treating seeds with the chemical colchicine.

The general occurrence of polyploidy in the angiosperms has led to a detailed study of the causes of chromosome doubling in gametes and egg cells. In 1923 De Mol found that diploid pollen grains could be induced in Hyacinthus by subjecting the bulbs to abnormal environ- 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. smart ball golf
