The below mentioned article provides a study note on the Artificial Induction of Polyploidy. In recent years, a number of methods have been worked out to induce polyploidy in plants. Some of them are described below: 1. By Radiation: Polyploidy can be induced in plants by exposing their certain parts, such as vegetative buds and flower buds, to radiations of [...]
