Abstract

The article is founded upon theories related to plants, dicotyledonous plants, the herbarium specimens preservation, and the instructional demands of Tan Trao University's students. This forms the basis for constructing the herbarium specimens from the Dicotyledonae. Consequently, the herbarium specimens of 40 dried plant specimens belonging to the Dicotyledonae was established, encompassing 22 families, 18 orders, and 6 classes. Additionally, a sulfur powder preservation technique was introduced for the plant specimens, alongside analyze the applications of the herbarium specimens in teaching various topics related to taxonomy, encompassing theoretical lessons concerning the attributes and practical functions of plant species within different families and orders. Furthermore, delve into practical lessons that involve analyzing the characteristics of Angiosperm plants. Measures have been proposed to augment the number of plant specimens in the imminent future, while information pertaining to taxonomic specimens is archived in Excel files to facilitate students' access. These findings represent a pivotal stride towards enhancing teaching and learning efficacy, while offering support to students and educators in comprehending and mastering knowledge concerning dicotyledonous plants.
