The present study was conducted to develop a protocol for an efficient in vitro mass propagation of two floriculturally important and threatened wild orchids namely Arundina graminifolia and Cymbidium aloifolium. Seeds were cultured on six different nutrient media, full and half strength MS (Murashige and Skoog, 1962) both in semi solid and liquid form, VW (Vacin and Went, 1949) semi solid medium, and KC (Knudson, 1946) semi solid medium. Maximum germination (89.75%) and early protocorm development (83.00%; 26.80 days) of C. aloifolium were recorded in half-strength MS liquid medium. Maximum germination (89.87%) in A. graminifolia was noticed in half-strength MS semi-solid medium and early and maximum protocorm formation (86.25%; 23.83 days) was first observed in half-strength MS liquid medium.
