The occurrence of arbuscular mycorrhizal fungi (AMF) in cultivated soils of Poland was characterized based on 15-year investigations. Spores of AMF were isolated from both field-collected root-rhizosphere soil mixtures and trap cultures established with a part of these mixtures. The mixtures were collected from under 41 plant species. The plant species most frequently sampled were <i>Hordeum vulgare, Triticum aestivum</i>, and <i>Zea mays</i>. Spores of AMF were found in 97,5% of the field-collected root-soil samples and in 95,5% of trap cultures. The AMF predominating in populations of the spores revealed were members of the genus <i>Glomus</i>. The spores recovered belonged to 36 species. The AM fungal species most frequently occurring in cultivated soils of Poland were <i>Glomus caledonium, G.constrictum, G.deserticola</i>, and <i>G.mosseae</i>.

Arbuscular Mycorrhizal Fungal

Arbuscular mycorrhizal fungal communities in northern temperate ecosystems must function during extremes in environmental conditions. However, it is not known if arbuscular mycorrhizal fungi that co-exist in soil communities have similar tolerances to stresses such as drought and freezing. The phenology of arbuscular mycorrhizal fungi was determined over one year in a community in southern Ontario, Canada. Five fungal species from the same community were then used to inoculate five plant species, in all possible combinations, and were subjected to either a freezing treatment or a drought treatment after which new seedlings were transplanted into the treated pots. The percent colonization of roots of each plant species was measured as the difference in mean colonization from the control. Freezing reduced percent colonization in almost every case, whereas drought resulted in both increased and decreased percent colonization. Fungal species responded differently to the treatments, and there was a pronounced plant × fungus effect. These results support the hypothesis that distinct functional groups of arbuscular mycorrhizal fungi exist, and these may determine plant community structure.Key words: arbuscular mycorrhizal fungi, freezing, drying, functional diversity.

Germination And Growth

Perennial herbaceous Fallopia is native to East Asia, and was introduced to Europe and North America in the 19th century as an ornamental plant. Fallopia has been spreading quickly and has naturalized in many countries. It is listed in the world’s 100 worst alien species. Fallopia often forms dense monospecies stands through the interruption of the regeneration process of indigenous plant species. Allelopathy of Japanese knotweed (Fallopia japonica), giant knotweed (Fallopia sachalinensis), and Bohemian knotweed (Fallopia x bohemica) has been reported to play an essential role in its invasion. The exudate from their roots and/or rhizomes, and their plant residues inhibited the germination and growth of some other plant species. These knotweeds, which are non-mycorrhizal plants, also suppressed the abundance and species richness of arbuscular mycorrhizal fungi (AMF) in the rhizosphere soil. Such suppression was critical for most territorial plants to form the mutualism with AMF, which enhances the nutrient and water uptake, and the tolerance against pathogens and stress conditions. Several allelochemicals such as flavanols, stilbenes, and quinones were identified in the extracts, residues, and rhizosphere soil of the knotweeds. The accumulated evidence suggests that some of those allelochemicals in knotweeds may be released into the rhizosphere soil through the decomposition process of their plant parts, and the exudation from their rhizomes and roots. Those allelochemicals may inhibit the germination and growth of native plants, and suppress the mycorrhizal colonization of native plants, which provides the knotweeds with a competitive advantage, and interrupts the regeneration processes of native plants. Therefore, allelopathy of knotweeds may contribute to establishing their new habitats in the introduced ranges as invasive plant species. It is the first review article focusing on the allelopathy of knotweeds.

Arbuscular mycorrhizal (AM) fungi are soil eukaryotes that belong to phylum Glomeromycota and have symbiosis with the vast majority of higher plants’ roots. AM fungi are believed to be coevolved with terrestrial plants, the abundance and diversity of AM fungal communities as a result are host plant dependent. A survey of AM fungi from the rhizospheres of medicinal plants in Northern Vietnam including gurma Gymnema sylvestre and turmeric Curcuma longa was carried out. From the extracted total DNAs of the medicinal plants’ rhizosphere soil samples, 35 mycorrhizal fungal species were identified by analyzing small subunit rRNA gene sequences. Result revealed that genus Glomus is the most abundant in the AM communities of G. sylvestre and C. longa, followed by Gigaspora and Acaulospora. Besides, AM species belonging to genera Scutellospora, Diversispora and Rhizophagus were observed in almost all rhizosphere soil samples. The spore counting by wet sieving and decanting method uncovered a variation in AM spore density of gurma and turmeric rhizosphere. In general, AM species were found more abundantly and more diverse in collected rhizome soil samples of C. longa (27 species belonging to 10 genera) than of G. sylvestre (17 species found belonging to 7 genera). The observed difference in AM communities of G. sylvestre and C. longa supports evidence for the dependence of AM fungal species on host plants, and indicates that AM fungi may have relation to the host plants’ secondary metabolite production.

The most frequently investigated plans were those from the families <i>Cupressaceae</i> and <i>Plantaginaceae</i>. Examination of trap cultures established from rhizosphere soil-root mixtures of the plans sampled revealed 20 described species of AMF, two undescribed <i>Glomus</i> spp., and three species of the genus <i>Glomus</i> that were difficult to recognize. The dominating AMF were members of the genus <i>Glomus</i>. Among the AMF found, <i>G. claroideum</i> was present, a species recorded for the first time in Poland. The distribution in Poland and in the world of the AMF encountered is shown.

Morphological characters of spores of <em>Acaulospora rehmii</em> and <em>Gigaspora margarita</em> (Glomeromycota) were described and illustrated. Spores of the two species were found in field-collected mixtures of rhizosphere soil and roots collected in Poland. Attempts to produce spores in trap cultures succeeded only with <em>G. margarita</em>. All attempts to establish one-species cultures of the two fungi failed. <em>Gigaspora margarita</em> was for the first time found in Poland and this paper is the first report of the occurrence of <em>A. rehmii</em> in Europe. The known distribution of the two fungal species in the world is also presented.
