In the wild, the size of orchids population often declines alarmingly (Solleveld, 2017). Although orchids are the l Conservation and propagation of an endangered medicinal orchid (anoectochilus setaceus lindl ) by in vitro technique argest family of flowering plants with almost 23,000 species (Cribb et al., 2003; Dressier. 1981; Fay & chase. 2009; Mabberley, 1997), Orchidaceae, moConservation and propagation of an endangered medicinal orchid (anoectochilus setaceus lindl ) by in vitro technique

It is well known for its value in horticultural, medicinal, and food usage (Fay, 2015; Gale et al., 2018). Due to the high revenue and medicinal benefits it brings, Aseraceus Lindl in Vietnam is overexploited in the wild, leading to exhaustion (Ban, 2005). hl 2007, in the Conservation and propagation of an endangered medicinal orchid (anoectochilus setaceus lindl ) by in vitro technique Decree No. 32/2006 / CP and the Vietnam Red Book, Aseraceus Llndl were classified into group IA (a, c, d) a group of endangered foiest plants (EN), anConservation and propagation of an endangered medicinal orchid (anoectochilus setaceus lindl ) by in vitro technique

Many pieces of research showed orchid seeds are better used for propagation thanks to the germination (Dutra et al., 2008; Godo et al., 2010; Park et al., 2000; Zeng et al Conservation and propagation of an endangered medicinal orchid (anoectochilus setaceus lindl ) by in vitro technique ., 2012), however, due to the seasonal aspects that stems and tops are believed as a better objective to enhance the productivity and recovery of biodConservation and propagation of an endangered medicinal orchid (anoectochilus setaceus lindl ) by in vitro technique
