Abstract :
In order to evaluate fungal colonization of roots of canola and some weed species eight separated trails were carried out as completely randomized design with 5 replications in 2017 and 2018. Experimental factores were fungal inoculation of Piriformospora indica and non inoculatrdcontrol on nine plant species of Brassica napus, Cardaria draba L., Sisymbrium irio L., Descuaraiana Sophia L., Capsella bursa pastoris Medik., Sinapis arvensis L., Avena ludoiviciana Dureu. and Phaiaris minor Retz.. After filling out pots with 0.6 lit of autoclaved soil, germinated seed were transferred in to the pots and were thinned after wards, leaving two seedlings per pot. Plants were harvested 10 weeks after transplanting. Total biomass, root length colonized and P.indica growth responses were analyzed. The results showed the effects of different fungi on canola and weed species growth were varied. The percentage of colonized roots was different among plant species. The highest root colonization by fungi was observed in canola by 50.49 percent and the lowest one was observed in S. arvensis L . Total dry weight of in species C.bursa-pastoris, C.draba, S.arvensis and P.minor was decreased by colonization of fungi. Fungi growth response of weeds was different from -16.33 to +50.49.
