摘要：
The movement of nutrients from soil towards the absorbing cells of the plant roots appears to be controlled by a mucilaginous interface composed prevalently of polysaccharides and characterized by a fibrillar structure. A network of Ca-polygalacturonate arranged in fibrils similar to those of plant roots has been obtained. In this paper such a formation is documented and discussed in structural terms.
