The study of the root-associated microbial complexes of affected and healthy rose plants of two cultivars (Grand gala and Royal velvet) grown in a greenhouse showed that the biomass of eukaryotic microorganisms in the rhizoplane and rhizosphere of healthy rose plants and in the surrounding soil was considerably lower than in the same loci of affected plants. In contrast, the biomass of root-associated prokaryotic microorganisms was higher in the case of healthy than in the case of affected rose plants. The root-associated bacterial complexes of both affected and healthy rose plants were dominated by the genera Arthrobacter, Rhodococcus, and Myxobacterium and did not contain phytopathogenic bacteria. The root-associated fungal complex of healthy roses was dominated by fungi of the genus Trichoderma, whereas that of the affected rose plants was dominated by the species Aureobasidium microstictum. The affected cane cuttings and cankers occurring on affected canes were found to contain Coniothyrium fuckelii (the causal fungus of rose stem canker) and sclerotia of Botrytis cinerea (the causal fungus of gray rot). The micromycete complex of healthy rose plants was not so diverse as was the micromycete complex of affected rose plants.
对温室中种植的两个玫瑰品种（大花月季和皇家天鹅绒）的患病和健康植株的根际微生物复合体进行研究，结果表明，健康玫瑰植株根际和根际土壤以及周围土壤中真核微生物的生物量明显低于患病植株的相同部位。相反，健康玫瑰植株的根际原核微生物生物量高于患病植株。患病和健康玫瑰植株的根际细菌复合体均以节杆菌属、红球菌属和粘细菌属为主，不含植物致病细菌。健康玫瑰的根际真菌复合体以木霉属真菌为主，而患病玫瑰植株的根际真菌复合体以微小 Aureobasidium 菌为主。在患病的茎插条和患病茎上出现的溃疡中发现含有 Fuckel 壳囊孢菌（玫瑰茎溃疡病的致病真菌）和灰葡萄孢菌的菌核（灰霉病的致病真菌）。健康玫瑰植株的微真菌复合体不如患病玫瑰植株的微真菌复合体多样。
