Establishment of a Rapid Breeding System for Bletilla striata

Bletilla striata (Thunb. ex A. Murray) Rchb. f., a species of perennial herb orchidaceae that has remarkable effects and high economic value, been intensively studied by many scholars. Although this seeds, the germination rate is exceptionally low, which leads to decreased germplasm resources increased market demand every year. To solve problem, study examined aseptic system direct seeding technology system. On Murashige Skoog (MS) medium, 2.0 mg/L 6-benzylaminopurine (6-BA) 1.0 naphthylacetic acid (NAA) were added before seed germination, 70 g/L banana juice 0.5 NAA when rooting. Then, seedlings transplanted mixed substrate humus, river sand, bark (volume ratio 3:1:1). The consists treatment, sowing, seedling raising, growth, transplanting. Turfy soil, Huangjiang residue, sand selected as substrate. results revealed was 91.8%, whereas plantlet regeneration 82.0%. After 180 days cultivation, plants could be finished seedlings. establishment B. provides safe, rapid, reliable production route for industrial development.
