Due to the impoverishment of agricultural and horticultural soils and replant diseases, there is a need to use bioproducts and beneficial microorganisms in order to improve the quality of soils and growth substrates. For this reason, research was undertaken to assess the impact of arbuscular mycorrhizal fungi and rhizosphere bacteria on changes in soil microbiology, the degree of colonization of plant...
The aim of the study was to evaluate selected bioproducts in terms of their effects on tree growth and the presence of mycorrhizal fungi in the roots of trees of two apple cultivars, ‘Topaz’ and ‘Ariwa’, grown under greenhouse conditions. The trees were planted in rhizoboxes and grown under the following fertilization regimes: 0 – control, NPK control, manure, Micosat F, Humus UP, Humus Active + Aktywit...
The aim of this study was to assess the growth and development of plants of three strawberry cultivars fertilized with selected biofertilizers under greenhouse conditions. The experiments were conducted in a greenhouse complex of the Research Institute of Horticulture in Skierniewice from February to July in 2013 and 2014. Plants of three strawberry cultivars, ‘Elsanta’, ‘Honeoye’ and ‘Elkat’, were...
The aim of the study was to determine the effect of various biopreparations on the growth of the apple root system, the number of spores of AMF, the total number of bacteria and microscopic fungi in the rhizosphere soil, and the degree of mycorrhizal association in the roots of two apple tree cultivars. The experiment was established in the spring of 2009 in the Experimental Orchard of the Institute...
The aim of the study was to determine the effect of mycorrhisation and mulching on the colonisation of the roots of‘Gold Milennium’ apple trees and ‘Ojebyn’ and ‘Tiben’ blackcurrant bushes by arbuscular mycorrhizal fungi. In order to assess mycorrhizal frequency, samples of roots were collected in the 2012 season from all of the experimental combinations (control, peat substrate, bark, sawdust, manure,...
Minirhizotron, a non-destructive technique is based on the application of transparent tubes, located in plant’s root zone. This method has been known since the beginning of 20th century and is used for plant root’s observations, especially in forest trees (Scots pine, Norway spruce, silver fir, birch), steppe grasses, vegetables and cereals. Minirhizotron technique is also applicable to pomological...
An experiment was carried out in a greenhouse of the Research Institute of Horticulture (RIH) to evaluate the effect of new organic fertilizers and amendments on root growth and mycorrhizal abundance and species richness in the rhizosphere of strawberry plants cv. 'Elsanta'. The plants were grown in rhizoboxes (sized 37 cm x 1.8 cm x 20 cm), filled with 1.85 kg of a podsolic soil collected from an...
The study was conducted in the Pomological Orchard and a greenhouse complex of the Research Institute of Horticulture in Skierniewice (RIH) in 2006-2008. Its aim was to identify arbuscular mycorrhizal fungi (AMF) present in the trap cultures containing rhizosphere soil and to determine mycorrhizal frequency (colonization) of AMF in the roots of apple trees 'Gold Milenium' and blackcurrant bushes...
