Features of development of hametophytes Botrychium multifidum (S.G. Gmel.) Rupr. culture in vitro
Abstract
The work is devoted to studying the influence of the type of culture medium and pH on the development of gametophytes Botrychium multifidum in vitro. The spores obtained from sterilized sporangia were suspended in liquid nutrient media with initial inoculum of 10000 spores per 1 ml. Nutrient media tested in the study were composed of full Murashige and Skoog or Knudson mineral salts supplemented with kinetin (1 mg/l) and pH level 4.8-6.4. All stages of development, from spore germination to thallus and gametophyte formation, were observed in tissue culture. A low level of germinating spores was noted.
