[Spatial peculiarities of rhizoplane colonization by microscopic fungi].
Spatial peculiarities in the colonization of the tomato, cucumber, and barley rhizoplanes by microscopic fungi were studied. The apical zone of roots was colonized with a limited number of R strategists (the order Mucorales, Fusarium sp., Aspergillus niger, and Mycelia sterilia). The fungal population of the root hairs and the basal zone of roots was 2- to 3-fold more dense due to the prevalence of K strategists. Fusaria, Fusarium oxysporum in particular, colonized roots in earlier terms than the genera Trichoderma, Penicillium, Gliocladium, and others. The F. oxysporum population was at a maximum in the rhizoplane zone nearest the root tip.
