RESULTS: In a greenhouse experiment, young wine grapes were planted in a field soil substrate and inoculated with one of three commercially available mycorrhizal inoculant products, or one of two locally collected whole soil inoculants. After 4 months of growth, inoculated vines showed no differences in plant biomass, colonization of roots by AM fungi, or foliar macronutrient concentrations compared to uninoculated field soil substrate. However, vines grown with local inoculants had greater shoot biomass than vines grown with mycorrhizal inoculant products.
CONCLUSIONS: Although effects from inoculations with AM fungi varied by inoculant type and source, inoculations may not improve young vine performance in field soils with a resident microbial community.
结果:在温室实验中,将年轻的酿酒葡萄种植在田间土壤基质中,并用三种市售菌根接种产品之一接种,或两种本地收集的全土接种剂之一。经过四个月的成长,接种的藤本植物生物量没有差异,AM真菌在根部定殖,或与未接种的田间土壤基质相比的叶面常量营养素浓度。然而,与使用菌根接种剂产品生长的葡萄藤相比,使用当地接种剂生长的葡萄藤具有更大的芽生物量。
结论:尽管接种AM真菌的效果因接种剂类型和来源而异,接种可能不会改善具有常驻微生物群落的田间土壤中年轻的藤本植物的表现。
