β¦ Synopsis
Somatic embryos were induced directly on adaxial surface of cotyledonary leaves within 8-10 days of culture on Murashige and Skoog medium containing 5.37 to 10.74 laM 1 -napthaleneacetic acid and 2.22 p.M benzyl adenine. Germinated embryos with shoot axes developed into complete plants after transfer onto half stength Murashige and Skoog medium containing 1.07 p.M 1 -napthaleneacetic acid. Histological studies suggested direct origin of somatic embryos with broad-base attachment.
