STUDY OF MYCORRHIZAL STATUS OF SOME GREEN HOUSE PLANTS

Authors have researched VA mycorrhizal symbiosis in root system of xer ophytous plants in the Botanical Garden of Nancy. They have examined 9 families and 22 species. For most of species, they have observed well developed YA endomycorrhizae. Nevertheless, these mycorrhizae have no t been observed in roots of Cactaceae and Aizoaceae. The presence of m ycorrhizae, even in plants that have been treated, incites to integrat e mycorrhizal symbiosis in techniques of cultivation of greenhouse pla nts.
