ABSTRACT

Arbuscular mycorrhgizal fungi that forming symbiotic associations with plants through roots. It forms the multi colonization systems with the roots and provide benefits to the host plants. The present study was conducted to evaluate the occurrence and distributions of Arbuscular mycorrhizal fungi in the rhizospheric soil of major weeds of District Charsadda. In the present study roots and rhizospheric soil of 15 weeds species belonging to 12 families were collected from Carrot field of District Charsadda and was investigated for the sporulation and root infections types. From the recorded results the highest spore density was found in Melilotus indica having spore number 276 which is followed by Malva neglecta and Sonchus asper having spore number 244, 214 respectively. The lowest spore density was recorded in Pao annua having spore number 35. The maximum Glomus density was found in Melilotus indica having mean value (83.67±1.65) whereas the maximum spore density was recorded for Acaulospora and Sclerocystis in the rhizospheric soil of Sonchus asper and Fumaria indica respectively. The root infection was also investigated which showed 20-85% root infection. The highest root colonization was recorded in Parthenium hysterophorus (39.67±11.02) whereas the lowest was found in Fumaria indica and Taraxacum officinale (6.33±5.51), (8.00±4.00) respectively. It is not necessary that the plants having high spore density will have high root colonization the host growth stage of plant influences the diversity and population of Arbuscular mycorrhizal fungi (AMF). Our study revealed that the AMF spore density and root infection is closely related to the soil physicochemical characteristics.
