Urban squares represent spaces for integration between society and the environment, functioning as important reserves of vegetation within the urban fabric. Thus, the objective of this work was to carry out a qualitative and quantitative diagnosis of the trees and shrubs that make up the squares of the municipality of Chapadão do Sul – MS. The study involved a census of arboreal and shrubby individuals with a minimum height of 1.3 m and DBH ≥ 15 cm, recording information on botanical identification, origin, health, and dendrometric dimensions. Diversity was analyzed using the Shannon Index (H′), and carbon stock was calculated using an allometric equation applied to the urban context. A total of 605 individuals were counted, distributed among 36 species and 20 botanical families, with Arecaceae being the most frequent family and Lagerstroemia indica (Resedá) the most frequent species. The diversity of the squares varied between moderate and high (H′ = 1.34 to 2.07). Praça 23 de Outubro presented the highest number of individuals and the greatest contribution to carbon stock, with 63.18 tC and 231.89 tCO₂eq. Praça Asa Branca, on the other hand, presented lower diversity and a low carbon stock (0.49 tC). The predominance of some species, mainly exotic ones, reduced the floristic balance in part of the studied areas. The total carbon stock of the squares amounted to 81.74 tC (300.00 tCO₂eq), demonstrating a significant contribution to mitigating urban emissions. The results indicate that urban afforestation in the municipality plays a significant environmental role, but requires diversification and continuous planning to increase ecological resilience and the benefits provided to the population.

These trees offer multiple uses, including timber production, charcoal production, and the restoration of degraded areas. Therefore, it is crucial to explore technologies that accelerate seedling growth and improve their quality for the establishment of robust plantations. Given this, the objective of this study was to evaluate the use of humic substances in the production and quality of Acacia mangium seedlings. The experiment was conducted in randomized blocks, testing six doses of humic substances (0, 10, 20, 30, 40, and 50 mL L⁻¹) with four replicates. Sixty days after sowing, the seedlings received the humic substance solution, at the tested doses, applied directly to the substrate. At 120 days after sowing, the following were measured: stem diameter, total height, relative chlorophyll index, maximum root length and volume, shoot and root dry mass per seedling, and the Height/Diameter, Shoot/Root ratios and Dickson Quality Index were calculated. The application of humic substances to the substrate of Acacia mangium seedlings resulted in changes in all parameters analyzed. For each parameter analyzed, there was an optimal dose that provided the greatest growth. Thus, it can be concluded that the use of humic substances applied to the substrate of Acacia mangium seedlings interferes with their formation. The doses at which the best parameters were obtained ranged from 10.0 to 21.1 mL L-1. This influence is more pronounced for the development of the root system. And, for the seedling quality parameters, the use of humic substances provides quality seedlings, and the dose to be applied varies with the parameter that is intended to be optimized.

In this context, the objective of this study was to evaluate the effect of seaweed extract and hydro-retentive gel in the direct seeding of native species. The study was conducted in the experimental area of the Federal University of Mato Grosso do Sul, in Chapadão do Sul, MS, established in October 2024, in an area of approximately 4,000 m². The spacing between the pits was 3.0 m x 3.0 m, arranged in a triangular spatial pattern, using Ascophyllum nodosum extract, hydro-retentive gel, a combination of A. nodosum and hydro-retentive gel, and a control, on five selected native species: Platypodium elegans, Anacardium humile, Enterolobium timbouva, Dipteryx alata, and Hymenaea courbaril. The variables and their respective monthly increments analyzed, in the period from September 2025 to October 2025, were: neck diameter, total height, and crown diameter. Each species showed a different response to the tested inputs. For P. elegans and E. timbouva, the combined application of algae and hydrogel showed greater responses. For A. humile and D. alata, the use of hydrogel stands out, while for H. courbaril, the isolated use of algae shows the best results. However, in general, the use of algae extract combined with hydrogel favored the initial growth of the studied native species.

However, the action of this biostimulant can be affected by the species, dose, and method of application. Among the forest species of commercial interest for the production of high-value-added wood, African mahogany (Khaya senegalensis) stands out. Thus, the objective of this work was to evaluate the extract of the algae Ascophyllum nodosum, and its method of application, on the formation and quality of Khaya senegalensis seedlings. In the experiment, a randomized block design was used, in a 5 x 2 factorial scheme, testing five doses of the Ascophyllum nodosum algae extract, in two application methods: on the substrate and by foliar application, with four replications. The treatments were applied 50 days after sowing, and 110 days after application, the following were measured: stem diameter, total height, number of leaves, leaf area, root length, root volume, root dry mass, shoot and total dry mass, height-to-diameter ratio, and Dickson quality index. Only stem diameter, total height, and height-to-diameter ratio showed no influence from the interaction between the studied factors. However, individually, both the dose and the method of application of the seaweed extract affected seedling development. Application via substrate provided higher values for stem diameter (4,8 mm) and total height (12 cm), while for the height-to-diameter ratio, only the applied dose influenced the results, with 13,2 mL L-1 providing the best outcome. Application via substrate provided better seedling performance, except for the number of leaves. The values for number of leaves, root volume, root dry mass, and total dry mass increased with the applied dose, while for leaf area, the 24 mL L⁻¹ dose showed a result 30.9% higher than the control. For root length, the 17,2 mL L⁻¹ dose showed the best performance, reaching 14,1 cm. The highest value for shoot dry mass (1,7 g) was obtained with the 24,3 mL L⁻¹ dose, while for the Dickson quality index parameter, the 26,4 mL L⁻¹ dose had the best result. It was concluded that the use of Ascophyllum nodosum extract influences the formation of African mahogany seedlings, favoring their development and quality. The application of the extract directly to the substrate provided higher morphometric parameters than those obtained by foliar application.
