- Аннотация: The inoculation method and light and scanning electron microscopy were employed to study the bacterial and fungal colonization of the rhizoplane during the early growth stages of tomatoes, cucumbers, onions, barley, and blue millet. To study the microbiota composition and make direct microscopic observations, a technique was designed for growing plants in nylon gauze, which makes it possible to obtain a root surface unshielded by soil particles. The extent of the rhizoplane colonization by bacteria was shown to be higher than that by saprotrophic mycelial micromycetes. On average, the projective bacterial coverage of the basal root zone and the zone of root hairs was 0.2-2%. Virtually no microbial cells were revealed on the root tip. The maximal bacterial colonization of the root surface (2-9%) was observed in the basal portion of roots, very close to the seed-root juncture. During the first weeks of plant growth, microbial associations characteristic of the rhizoplane were formed; they included a group of species common to different plants and species specific for particular plants. We identified certain micromycete species which predominantly colonize the apical root zone.
