An efficient micropropagation protocol was developed for an important
medicinal plant, Plantago major L. For this purpose, it is recommended
to culture shoot-tips on modified MS medium [412.5 mg dm(-3) NH4NO3 a
nd 340 mg dm(-3) KH2PO4] supplemented with 50 g dm(-3) glucose and 0.5
mu M 6-benzylaminopurine. Maximum rooting frequency was obtained at 1
mu M naphthaleneacetic acid.
