Media for induction of somatic embryogenesis from immature cotyledonar
y tissues of Azadirachta indica (Neem) were determined. Callus was ini
tiated on Murashige and Skoog medium supplemented with 0.5 mg . liter-
1 of indol-3 acetic acid, 1.0 mg . liter-1 of 6-benzyl amino purine, a
nd 1000 mg . liter-1 of casein hydrolysate. Effect of kinetin was also
studied for embryo induction. Carbohydrate source in the form of sucr
ose and glucose alone and in combination was tested for embryogenic ef
ficiency. Seventy percent embryos showed germination. Healthy plants w
ere potted in sand and soil. Histologic studies confirmed indirect som
atic embryogenesis.
