Study on the Root Structure of Rehmannia glutinosa in Different Habitats

The free-hand section comparison of the roots of Rehmannia glutinosa in different habitats shows that the root structure of Rehmannia glutinosa in different habitats is significantly different: the test group (salt environment) has a thinner pericarp, smaller cells and tightly arranged cells; The cortical cells are small and dense; the xylem cells of the vascular column are larger, the ducts are thin and the myelin rays are obvious. In the control group (normal habitat), the rhizomes of rhizome glutinosa had thick pericytes, large cells and loose arrangement; the cortical cells were large and loosely arranged; the volume of xylem cells in vascular columns was relatively small, the ducts were thick and few, and the myelin rays were not obvious.
