Effects of soil properties and botanic composition on arbuscular mycorrhizal fungus (AMF) from gramineae family plants

Abstract

Mycorrhizae is the term used to describe the mutual istic associations between specizalized fungi and roots of higher plant. Numerous plants strongly depend upon mycorrhizae for optimal growth. Studies of mycorrhi zae are unsufficient in rangeland in Turkey. The aim of the present study is to establish interrelationships between AM colonization status with the physico-chemical prope rties of the soil and botanic composition.To achiev e these objectives, rhizosphere soil samples from Gramineae family plants were collected in June and July 2010 . Soil samples were taken for determination of several soil characteristics. In addition, vegetation analyses were carried out. AMF was determined that 64% plants colonized by variable range (7.14%-41.38%) of arbuscular- mycorhizal fungi and established symbiotic relation ship. Glomus genus was determined as fungal symbiont of all root samples. The rangeland soils were characte rized by high organic matter, high total nitrogen, low electrical conductivity and low lime content. At the present day arbuscular mycorrhizal inoculation must use in range rehabilitation. However, information on the AMF potential in our rangeland is still lacking. Therefore, this study would provide fundemental information on range rehabilitation studies in degraded rangeland ecos ystems of Western Black Sea region. Also, this study contributed to the AMF map of Turkey for Bartın.
