Objective
The discipline aims to present and discuss the structural diversity of underground plant systems, with
emphasis on their morphology, anatomy, and ecological significance. To enable students to identify
different types of underground organs, understand their adaptive functions, and their role in plant
regeneration, especially in environments affected by disturbances such as fire. To encourage critical
analysis of scientific literature and the integration of structural and ecological aspects of these systems.
Content
Morphological and anatomical study of the main types of underground systems: rhizomes, rhizophores,
xylopodia, lignotubers, tuberous roots, gemmiferous roots, soboles, bulbs, corms, and tubers.
Classification of bud types and their relation to sprouting capacity and vegetative propagation. Analysis
of the diversity and function of these organs in different vegetation formations, with emphasis on the
Cerrado biome. Ecological importance of underground systems in post-fire regeneration and adaptation
to adverse environmental conditions. Introduction to methodologies applied to the structural and
ecological characterization of these organs.
