Impact des huiles essentielles de l'ortie, du romarin et de l'azolla sur la dynamique de croissance végétative des gazons : Perspectives pour une gestion durable des espaces verts.

Abstract

Grass is considered an essential part of our environment; however, it can face various challenges and pressures that negatively affect it. Biostimulants help improve non-biological pressures. This study was conducted within the LPPA/INES laboratory, where the effectiveness of treatment with plant-derived biostimulants was monitored, and its importance and impact on the growth and development of grass were presented. To assess this impact, we compared extracts from three plants (ortie, rosemary, azolla) with each group divided into three different concentrations: horsetail, rosemary, and azolla extracts in 30 pots, measuring the length of leaves, roots, stems, and germination rate. Samples taken from different plants were analyzed in the laboratory, where we studied the content of polyphenols (3.95 ± 0.400), flavonoids (82 ± 3.95), and chlorophyll (48.23 ± 0.22), as well as the protein level (2.13 ± 27.50). Revised morphological measurements showed that the application of these products stimulates plant growth, increases chlorophyll levels (1.02 ± 48.81), and improves grass quality. According to the results obtained, each treatment has a specific effect on different parts of the plants. Therefore, it is necessary to implement a combination of these treatments to maximize their benefits.
