Sažetak
Endoparasitic nematodes and arbuscular mycorrhizal fungi (AMF) are biotrophic and share plant roots as resources of food and space. They have substantial but contrary effect on plant health. Due to direct competition for space and mutual antagonism, AMF has been regarded as potential for AMF plants to provide resistance against plant parasitic nematodes. Endoparasitic nematode, such as Pratylenchus spp. directly affect AMF by feeding on and killing cells that contribute to AMF nutrition. Contradictory results have often been reported. The objectives were to determine the populations of endoparasitic nematodes and colonization of soybean root by AMF and its relationship. The study was conducted in soybean, in 2006 and 2007, at the site of Agricultural Institute Osijek, Croatia. The average number of nematodes per gram of soybean roots were 905, 82 and colonization by AMF was 42, 28%.The significantly moderate positive correlation (r=0, 418) was observed between endoparasitic nematodes and AMF in soybean roots. The results indicate the occurrence of interaction between nematodes and AMF in the soybean root system. Since, positive correlation between two organisms was observed as well as high yields, soybean cultivar proved to poses nematode tolerance traits and AMF cannot be observed as a IPM tool. Relationship between endoparasitic nematodes and AMF should be further studied to reveal mechanisms of action.
