Özet:

Piriformospora indica is an endophyte with the ability to colonize roots and it is cultivable. It forms a specific type of mycorrhiza symbiosis with a broad spectrum of plant species, promoting plant growth and biomass production and also induction of resistance against pathogens. In this study our aim is to test Piriformospora indica against powdery wildew in barley and Puccinia striiformis in wheat to determine best application method of P. indica to assess the induction of resistance. Also we aimed to develop a procedure that enables the usage P. indica in large scale agricultural applications. To achieve our goals, we applied P. indica in different spore concentrations and in different form as powder and liquid cultures. After establishing symbiosis with P. indica on plants, the plant leaves were infected with pathogens. The disease formations were evaluated in comparison with the control group of plant samples (without Piriformospora indica)
