- Petiole explants from in vitro grown Echinacea purpurea were cultured on specific growth media to regenerate shoots using benzyladenine and naphthaleneacetic acid, along with varying colchicine concentrations for inducing polyploidy.
- A duration of colchicine treatment longer than 7 days was necessary to successfully produce tetraploid shoots, with the most effective treatment being 120 mg/L of colchicine for 28 days, resulting in 23.5% of shoots being tetraploid.
- Tetraploid plants exhibited traits such as larger stomata, thicker and more branched roots, and shorter inflorescence stalks compared to diploid plants, while chimeric plants showed a low
