Plant histology

As animal tissues, plant tissues can be fixed, included in paraffin and stained. For this, it is needed to adapt the fixative nature, the fixation time and the kind of hitologic staining. We propose a new staining for plant histology : the Safranin and Astra Blue staining. This staining identifies the lignified or suberified plant wall in some root peas for example. Lignin is stained red by safranin and cellulosic walls are stained blue by Astra Blue.
