In Algeria, in the semi-arid and arid areas cereal production is limited because of many constraints like lack of mineral elements (phosphorus and nitrogen), low organic matter and an insufficient water reserve due to the low rainfall. Most researches on durum wheat (Triticum durum Desf.) are undertaken to increase its productivity. In recent years several methods have been used including using microorganisms. Arbuscular Mycorrhizal fungi (AMF) appear to have important roles in plants in various soil conditions. In Algeria and particularly in the eastern regions, the diversity of AMF spores in the soil is so far little studied. In this context this study focuses on the study of the diversity and the abundance of AMF spores in Triticum durum Desf. fields in arid, semi-arid and coastal regions. Soil samples were collected and characterized and the spores isolated by the wet sieving methods were observed, counted and identified. The results of the physic-chemical characterization of all soil samples reveal a clay loam, loam clay and loam sandy soils with an alkaline pH (7.54-8.27), a total nitrogen content from 0.023 to 0.082% and phosphorus content ranging from 1.63% to 7.74%. We noted the presence of several morphotypes that were classified as follow: Glomeraceae, Acaulosporaceae and Scutellosporaceae with a predominance of Glomeraceae in different sites depending on climate and soil type. The presence of these families demonstrates a biodiversity of the eastern wheat fields of Algeria.

Materiał badawczy stanowiło ziarno otrzymane z doświadczeń polowych prowadzonych w latach 2008–2011 na terenie Gospodarstwa Doświadczalnego Felin, należącego do Uniwersytetu Przyrodniczego w Lublinie. Celem pracy była ocena szklistości ziarna odmian i linii następujących gatunków pszenicy: a) formy jare: Triticum durum (Desf.), T. aestivum ssp. sphaerococcum (Percival) MacKey, T. turgidum (L.), T. monococcum (L.), T. dicoccum (Schrank) Schübler, T. polonicum (L.), T. timopheevii (Zhuk.); b) formy ozime: T. durum (Desf.), T. aestivum ssp. spelta (L.) Thell., T. monococcum (L.), T. dicoccum (Schrank) Schübler, T. macha (Dekapr. et Menabde), T. vavilovii (Thum.) Jakubz., a jako wzorca użyto odpowiednio formy jarej i ozimej T. aestivum ssp. aestivum (L.). Formy ozime pszenicy, niezależnie od gatunku i odmiany, charakteryzowały się znacznie mniejszą szklistością w porównaniu z formami jarymi. W obrębie badanych genotypów pszenicy jarej najwyższym poziomem szklistości ziarna odznaczała się T. durum odmiana Puławska Twarda, a najniższym – T. polonicum. Spośród gatunków pszenicy ozimej najwyższą szklistością ziarna wyróżniała się pszenica twarda (odmiana Komnata), natomiast najmniej szkliste ziarno tworzyła pszenica orkisz (T. aestivum ssp. spelta) − Spelt INZ.

Abstract. Mahulette AS, Alfian A, Kilkoda KA, Lawalata IJ, Marasabessy DA, Tanasale VL, Makaruku MH. 2021. Isolation and identification of indigenous Arbuscular Mycorrhizal Fungi (AMF) of forest clove rhizosphere from Maluku, Indonesia. Biodiversitas 22: 3613-3619. Forest clove is classified as wild-type and endemic to the Maluku (Moluccas) Islands, Indonesia. The different condition of growing areas causes various types of Arbuscular Mycorrhizal Fungi (AMF) associated with forest clove. The study aimed to identify and obtain indigenous AMF inoculums from the forest clove rhizosphere from two distribution areas in Maluku. The results of AMF identification found two types of spores from the genus Glomus in the rhizosphere of forest cloves from Ambon Island with a spore density of 35/50 g of soil. In comparison, three spores were found in Seram Island, two from the genus Scutellospora and one from the Acaulospora. With an overall spore density of 5/50 g of soil. After culture trapping, there was a change in type and an increase in spore density in soil samples from the rhizosphere of the two forest clove distribution areas. Soil samples from Ambon after trapping culture obtained two new types of spores from the genus Acaulospora with a total spore number of 57/50 g soil while in soil samples from Seram found three new types of spores from the genus Glomus with a total spore count of 104/50 g of soil.

The present study evaluated the diversity of arbuscular mycorrhizal fungi (AMF) associated soils from three ecosystems grown with pasture colosoana in three localities of the Department of Sucre, Colombia. Soil samples were collected, AMF spores isolated, count of spore was made and morphotypes isolated were classification at the level of species or genera. We found that the genus of AMF over prevailing in native and compacted soils in the three selected municipalities is the genus Glomus, followed by other genera to a lesser extent. In general the soils that presented greater wealth of genres of HMA were those of the municipality of San Marcos, while the lowest richness was found in the municipality of Sincelejo.

ABSTRACT The impact of land use intensity on the diversity of arbuscular mycorrhizal fungi (AMF) was investigated at eight sites in the “three-country corner” of France, Germany, and Switzerland. Three sites were low-input, species-rich grasslands. Two sites represented low- to moderate-input farming with a 7-year crop rotation, and three sites represented high-input continuous maize monocropping. Representative soil samples were taken, and the AMF spores present were morphologically identified and counted. The same soil samples also served as inocula for “AMF trap cultures” with Plantago lanceolata, Trifolium pratense, and Lolium perenne. These trap cultures were established in pots in a greenhouse, and AMF root colonization and spore formation were monitored over 8 months. For the field samples, the numbers of AMF spores and species were highest in the grasslands, lower in the low- and moderate-input arable lands, and lowest in the lands with intensive continuous maize monocropping. Some AMF species occurred at all sites (“generalists”); most of them were prevalent in the intensively managed arable lands. Many other species, particularly those forming sporocarps, appeared to be specialists for grasslands. Only a few species were specialized on the arable lands with crop rotation, and only one species was restricted to the high-input maize sites. In the trap culture experiment, the rate of root colonization by AMF was highest with inocula from the permanent grasslands and lowest with those from the high-input monocropping sites. In contrast, AMF spore formation was slowest with the former inocula and fastest with the latter inocula. In conclusion, the increased land use intensity was correlated with a decrease in AMF species richness and with a preferential selection of species that colonized roots slowly but formed spores rapidly.
