The root-colonizing actinomycete complexes of genotypically different barley plants grown in soddy podzolic soil were found to contain streptomycetes of the sections Cinereus (series Chromogenes, Achromogenes, and Aureus) and Roseus (series Fradiae), dominant being streptomycetes of the section Cinereus ser. Chromogenes. The abundance and diversity of soil streptomycetes in the barley rhizoplane increased in the order: var. 999-93 < var. Kumir < var. Novichok < var. 889-93. Experiments revealed functional specificity in the root-associated actinomycete complexes of different barley varieties. The actinomycete complex colonizing the barley var. 999-93 roots was distinguished by a wide range of utilizable root exudate metabolites and a low occurrence rate of antagonistic species.
在灰化土中种植的基因型不同的大麦植株的根际定殖放线菌复合体，被发现含有灰褐类群（产色链霉菌系列、不产色链霉菌系列和金色链霉菌系列）和粉红类群（弗氏链霉菌系列）的链霉菌，其中灰褐类群产色链霉菌系列的链霉菌占主导地位。大麦根际土壤链霉菌的丰度和多样性按以下顺序增加：999 - 93品种 < 库米尔品种 < 诺维乔克品种 < 889 - 93品种。实验揭示了不同大麦品种根际相关放线菌复合体的功能特异性。定殖在大麦999 - 93品种根系上的放线菌复合体的特点是可利用的根系分泌物代谢产物种类广泛，拮抗物种的出现率较低。
