Micro-morphological and morphometric characters analysis of Silica Bodies (SB) on leaf epidermal cells of five selected taxa in the Sub-family panicoideae based on Analytical Microscopy (AM): A systematic approach

Shilpa Dinda, Souradut Ray, Amal Kumar Mondal*


Plants have unique capability to deposit silicon (si) with and between the cells and thus creating casts of the cells commonly known as silica bodies (plant stones). Silicon are very abundantly present only in the family Poaceae among monocotyledon. These silica bodies contain the composition of silicon to form different structural diversity of stone cells like long or short bar with rounded or semi rounded spheres dumbbell shaped, sinuous elongated rectangular, narrow elliptical rectangular, randle, polylobed and cross shaped etc. Light (LM), Polarized (PM), Fluorescence Microscopy (FM) and Scanning Electron Microscope (SEM) were used for better micro-morphological study. These micro characters might be applied numerically by UPGMA method to solve different taxonomic problems within familial, generic and species level and compared to other systematics.
