Role of Plant Growth Regulators on in vitro Organogenesis in Platycodon grandiflorum

Platycodon grandiflorum is an important traditional medicinal plant found in North East Asia (including China, Japan, and Korea.) that mainly used to mitigate cough, phlegm, sore throat, lung abscess, chest pain, dysuria, and dysentery. The current investigation was carried out to explore the potentiality of shoot and root organogenesis of P. grandiflorum with multiple types of petals in response to various plant growth regulators.
