Growth reactions of a Gremmeniella abietina isolate and Scots pine embryogenic tissue cultures differ in a host–parasite in vitro system
Forest Pathology 30 (5), 285-295
Abstract: The aim of this study was to screen Scots pine embryogenic tissue culture material to Gremmeniella abietina. According to the results Scots pine (Pinus sylvestris) embryogenic tissue lines (27 lines) could be ranked based on significant differences in G. abietina effects estimated by changes in glucosamine concentrations, growth, and dry matter contents of inoculated tissue pieces. The ranking order of the extreme tissue lines stayed basically similar, regardless of the variable measured. These findings imply a possibility to use the ranked embryogenic tissue lines in more detailed investigations of interactions between G. abietina and its host. This is the first report of using embryogenic tissue cultures in studying host–parasite interaction between Scots pine and G. abietina.
