Highlighting the Structures and Patterns of Fungal Colonization in the Species Festuca rubra

Abstract

Grasslands are the most dynamic ecosystems are characterized by high biodiversity both above-ground and underground. The biggest problem in these ecosystems is oligotrophy. The phenomenon affects the stability and resilience of these ecosystems, increasing the impact of biological processes. The symbiotic relationship between plants and mycorrhizas is a natural option with a great impact on maintaining the high natural value of ecosystems. This article aims rating colonization Festuca rubra, dominant in a mountain grassland ecosystem. Roots were cleared and stained with ink for the detection of mycorrhizas in roots. All root samples were analyzed with an optical microscope for the detection of mycorrhizal structures. The results obtained highlight a main mycorrhizal pattern as well as specific subcategories. Both types of arbuscules were identified: Arum and Paris. The results obtained highlight a main mycorrhizal pattern as well as specific subcategories. Vesicles are structures with a constant lack of consistency, which indicates their fluctuating nature. The mycorrhizal pattern of Festuca rubra as the dominant species in the pratol ecosystem may be the first step towards a more detailed understanding of the fungal strategy as well as the increased importance in the stability of the pratol ecosystem.
