Sažetak
Endoparasitic nematodes (EN) have detrimental effect on plant growth but also substantialy affect nutrient dynamics in ecosystem. Association of plants with arbuscular mycorrhizal fungi (AMF) increase plant access to immobile soil minerals, and thereby increase plant growth rates. Mycorrhizae influence the colonization of roots by other microorganisms and may reduce the susceptibility of roots to nematodes. Since, there is direct competition for space, the mutual antagonism between EN and AMF has been observed. The objectives were to determine the effect of soybean cultivars on EN density in roots and root length colonization by AMF and their correlation. The cultivar effects and relationship between EN and AMF colonization in soybean roots has been observed in roots of seven soybean cultivars, in randomized complete block design experiment. Significant differences were found between cultivars for the root infection by EN and AMF colonization depending on the month of investigation. Relationship between the cultivars concerning interaction between EN and AMF was found to be positive or negative depending on the cultivar and the month. Three cultivars (OS-1-0, OS-2-I, and OS-3-I) had strong negative correlation while the strength of correlations of other cultivars were weak. Our results suggest that mutual inhibition between EN and AMF in soybean roots existed depending on the cultivar and the plant genotype as such affects their relationship.
