Abstracts |
Plantago lanceolata was grown in a two-factor
experiment with and without arbuscular mycorrhizal fungi (AMF)
and with and without the addition of 2 g cellulose per litre of
a sand-soil based cultivation substrate. Results showed a
significant change in plant growth and development of arbuscular
mycorrhiza represented by a mixed population of three symbiotic
fungi: (1) Glomus claroideum; (2) Glomus geosporum; and (3)
Glomus mosseae in cellulose amended substrate. Higher AMF
colonization of roots after I I months of cultivation in the
cellulose amended treatment was found compared to the unamended
treatment. Sporulation of AMF was inhibited by cellulose at the
first harvest (5-month-old plants), but it was substantially
stimulated at the second harvest (I I-month-old plants). A
positive effect of cellulose on the total length of extraradical
mycorrhizal mycelium at the second harvest was observed.
Significant changes in amounts of bacterial CFU and of the
saprophytic fungus Penicillium pinophilum in the substrate
amended with cellulose were recorded after I I months of
cultivation. No significant changes in total and oxidizable
carbon in AMF-inoculated substrate were found. The contribution
of AMF extraradical mycelium to the total content of organic
matter in the substrate represented less than 2%. The study
showed the importance of cellulose, a common organic material in
the soil, for development of AMF and saprophytic microfloral
population in soil-based cultivation substrate poor in organic carbon.
