Abstract:

The aim of this study was to examine the symbiosis relationshipbetween some arbuscular mycorrhizal fungi (AMF) and Salsola laricina (Chenopodiaceae), a non-mycotrophic plant speciesand its effect on improving plant growth parameters. Initially, the development of AMF density was monitored through two parameters including evaluation of mycorrhizal colonization of plant roots and density measurement in the soil under field conditions. Then, the spores were counted and the highest four morphotypes were isolated for morphological identification and preparation of inoculum to culture. The seeds of S. laricana were planted inside pots under greenhouse conditions and were inoculated by four isolates of AMF including Archaeospora schenckii, Glomus deserticola, Scutellospora erythropa, and Septoglomus constrictum and one treatment remained non-inoculated as control. High root colonization of the plants was found at six months after inoculation (46%) where the highest morphotypes density belonged to S. constrictum (No./20 g soil-1), suggesting the importance of AMF for plant growth efficiency. The AMF symbiosis generally improved the growth related to the height and weight of shoot and root of S. laricana that were significantly increased. The results led to the conclusion that, identification of interactions between plants, soil properties, and AMF colonization can contribute to improve management of ecosystems.

Arbuscular Mycorrhizal Fungi and Alien Plant Species

The invasion success of alien plant species depends, amongst other things, on their functional traits [4] and the susceptibility of ecosystems. There is now increasing interest in including biotic interactions particularly mutualistic associations [5], into frameworks assessing alien plant invasions, as they help bridge the invisibility and invasiveness features. The great majority of terrestri...

INTRODUCTION OF SOME NEW ARBUSCULAR-MYCORRHIZAL FUNGI (AMF) FROM CITRUS RHIZOSPHERE OF IRAN

During 2001-2002, a total number of 164 soil-root samples were collected from citrus orchards of six provinces, namely, Fars, Gilan, Mazandaran, Kerman, Hormozgan and Sistan va Baloochestan. Soil samples were decanted and centrifuged and spores were collected and examined. Out of 23 identified species, five species were recognized new to Iran mycoflora. New species are as follows: Gomus albidum...

plant growth promoting rhizobacteria and arbuscular mycorrhizal fungi can inhanced plant growth by increasing nutrient uptake. in order to investigate the effect of pgpr and amf on some morphological parameters, macro (nitrogen, phosphorus, potassium, calcium and magnesium) and micro (iron, zinc and copper) nutrients uptake, percentage of root colonization and some morphological factors of pepp...

Density dependence and interspecific interactions between arbuscular mycorrhizal fungi mediated plant growth, glomalin production, and sporulation

Functional differences between the arbuscular mycorrhizal fungi Glomus intraradices Schenk and Smith and Scutellospora heterogama Nicolson and Gerdemann as they affect Persea americana Mill. growth, glomalin, and fungal sporulation were examined by varying the composition and relative density of the two fungi over a gradient of available phosphorus (P). The plant benefit provided by these mycor...
