Abstract

Fine roots and ectomycorrhizal root tips were sampled in a Norway spruce (Picea abies (L.) Karst.) stand in the eastern part of the Belgian Ardennes. The cellular and partly subcellular localizations of aluminum and lead were identified by the micro-analytical laser microprobe mass analysis (LAMMA) technique. In fine roots with secondary structure, localization of aluminum was limited to the peripheral cell layers. Lead was found in the outer layers, and also in the primary phloem. Aluminum penetrated the mycorrhizal mantle, but lead was seldom detected in ectomycorrhizae.

摘要

在比利时阿登东部的一片挪威云杉（Picea abies (L.) Karst.）林中采集了细根和外生菌根根尖。通过微分析激光微探针质谱分析（LAMMA）技术确定了铝和铅在细胞及部分亚细胞水平上的定位。在具有次生结构的细根中，铝的定位仅限于外周细胞层。铅在外层以及初生韧皮部中被发现。铝穿透了菌根套，但在外生菌根中很少检测到铅。
