THE INFLUENCE OF MYCORRHIZAE ON GERMINATION OF CORAL BELLS (Heuchera sanguinea 'Metallica')

Sa？etak Species of the genus Heuchera L. belong to the group of perennials that are commonly used for decorating flowerbeds and rockeries. Besides flowers they possess attractive leaves, which makes them attractive throughout the year. In generative reproduction of a perennials slow germination is often a problem which raises production costs. Therefore, it is desirable to have as short a period from sowing to germination. The aim of this study was to determine the effect of mycorrhizal fungi Glomus mossae in two different concentrations of inoculums on the dynamics of seed germination cultivar Heuchera sanguinea Engelm. 'Metallica'. Seeds was sown in substrate previously inoculated with spores of mycorrhizal fungi Glomus mossae in two different concentrations of 2,5 vol% and 5 vol%. The research results show that the mycorrhizal fungus Glomus mossae had a positive effect on the dynamics of the germination compared with the control. The positive effect of Glomus mossae lacked at the development of leaves, to a lesser concentration of inoculums in the substrate (2,5 vol%), compared with control
