Propagation of orchids (Orchidaceae) plans (Dactylorhiza fuchsii druce, Dactylorhiza majalis rchb.) by dividing protocorm

The main objective was to explore the possibilities of cloning plants orchids dividing protocorm. The experiment was conducted in the Laboratory of Biotechnologies of the Institute of Horticulture, Lithuanian Research Center for Agriculture and Forestry. Research was carried out to select and use common spotted orchid (Dactylorhiza fuchsii Druce) and the western marsh-orchid (Dactylorhiza majalis Rchb.) already sprouted seeds protocorms. Common spotted orchid and western-marsh orchid protocorms original shoot explant with embryo survival results were similar. Total observation time, western marsh-orchid has lost only a few explants and common spotted orchid survived all explants with initial shoot bud. Western marsh-orchid's average shoot height was higher than common spotted orchid. However, common spotted orchid completely did not form additional shoots. Western marshorchid characterized by the formation of additional shoots. Protocorm dividing is an effective means to increase the yield propagated marsh orchid, but its effectiveness depends on the plant speciesAgronomijos fakultetasVytauto Didžiojo universiteta
