Abstract

In order to determine the behavior of longitudinalvariability in the number of spores of arbuscular mycorrhizalfungi (AMF) Glomus hoi-like in beds, using Brachiariadecumbens as a trap plant, a study was performed. To complywith it, the crop was inoculated with Glomus hoi-like (INCAM-4),provided by the AMF strain collection of INCA, on a claysubstrate. Samplings were conducted at 60, 90 and 120 daysafter seed germination in which the beds were subdivided intothree equal parts and took a sample of five sub-samples in thedepth of 0-20 cm, determined the number of spores. Todetermine the spatial variability in the number of spores in asample beds composed of three sub-samples every 1.5 m alongthe plant, each sample was tested for the number of sporesand the contents of some chemical indicators substrate. Acorrelation between the number of spores and chemicalindicators of the substrate were mode. The number of sporesin both periods was increasing with time and showed a highvariability throughout the bed. The highest production ofspores were found in the period from June to October. Thecorrelation between the amount of spores and chemicalindicators showed poor results with very low correlationcoefficients, which showed that these indicators are notresponsible for the variability the spore production.
