Description of an Anatomical Structure and Changes of Microstructure through the Grave Yard Test on Treated and Untreated Three-Year-Old Gigantochloa scortechinii via Electron Microscopy

The microstructures of a variety of tropical bamboo species were studied. Three-year-old Gigantochloa scortechinii were harvested and separated into various places and postures. Through the vacuum pressure, sap displacement, and soaking technique, bamboo samples were treated with copper-chrome-arsenic (CCA), ammonia-copper-quaternary (ACQ), and a borax-boric-acid (BBA). Electron Microscopy (EM), particularly Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM), is then used to examine the samples’ microstructure. For SEM and TEM, the coating process and spurr resin techniques were used. The changes in vascular bundles, fibres, and parenchyma cells at the internodes and nodes, as well as the exterior, middle, and inner sections of natural and preservative-treated bamboos, were studied. The properties of the bamboo species were found to be comparable, while the anatomical aspects and microstructure were found to be distinct. This research also uses SEM and TEM micrographs to show the impacts of treated and untreated samples in a ground contact test.
