The potential use of mycorrhiza as a bioremediation agent for soils contaminated by radiocesium was evaluated in a greenhouse experiment. The uptake of (137)Cs by cucumber, perennial ryegrass, and sunflower after inoculation with a commercial arbuscular mycorrhizal (AM) product in soils contaminated with (137)Cs was investigated, with non-mycorrhizal quinoa included as a "reference" plant. The effect of cucumber and ryegrass inoculation with AM fungi on (137)Cs uptake was inconsistent. The effect of AM fungi was most pronounced in sunflower: both plant biomass and (137)Cs uptake increased on loamy sand and loamy soils. The total (137)Cs activity accumulated within AM host sunflower on loamy sand and loamy soils was 2.4 and 3.2-fold higher than in non-inoculated plants. Although the enhanced uptake of (137)Cs by quinoa plants on loamy soil inoculated by the AM fungi was observed, the infection of the fungi to the plants was not confirmed.
在温室实验中评估了菌根作为修复受放射性铯污染土壤的生物修复剂的潜力。在受（137）Cs 污染的土壤中接种了一种商业丛枝菌根（AM）产品后，研究了黄瓜、多年生黑麦草和向日葵对（137）Cs 的吸收情况，同时将非菌根的藜麦作为“对照”植物。在接种 AM 真菌后，黄瓜和黑麦草对（137）Cs 的吸收效果不一致。AM 真菌对向日葵的影响最为显著：在壤土和壤土上，植物生物量和（137）Cs 的吸收均增加。在壤土和壤土上，AM 宿主向日葵体内累积的总（137）Cs 活性分别比未接种植物高 2.4 倍和 3.2 倍。尽管在壤土上接种 AM 真菌的藜麦植物对（137）Cs 的吸收增强，但尚未确认真菌对植物的感染。
