Material and methods: In this article we present for the first time the histo-anatomical structure of roots, stems and leaves of Robinia pseudoacacia L. species, by using photomicrography technique and staining with genovez reagent.
Results: The research results showed that the root and stem have secondary structure. The leaf has bifacial dorsiventral structure.
Conclusions: Microscopic analysis proved to be a valuable tool, very useful in specifying the characteristic anatomical features of the root, stem and leaf of Robinia pseudoacacia L.
