A method has been developed for staining the phloem so that its ramifications can be observed directly in thick preparations. This method is based on clearing the material with lactic acid, staining with lacmoid and observing it in sodium lactate. Phloem anastomoses between the primary vascular strands of stem internodes were found to be common in many plant species (18 out 26 studied). These anastomoses are possible channels for the lateral distribution of materials in the stem and for movement of assimilates upwards from the leaves.
已经开发出一种方法来对韧皮部进行染色，以便可以在厚切片中直接观察其分支。该方法基于用乳酸对材料进行透明处理，用乳香酸染色，然后在乳酸钠中观察。在许多植物物种（研究的 26 种中有 18 种）的茎节间初生维管束之间发现了韧皮部吻合。这些吻合可能是物质在茎中侧向分布的通道，也是从叶子向上运输同化产物的通道。
