Item Diagnóstico dos viveiros de mudas florestais no município de Gravatá - PE(2024-10-03) Lima, Pollyana Gomes da Silva; Freitas, Eliane Cristina Sampaio de; http://lattes.cnpq.br/7525975084334972; http://lattes.cnpq.br/3458909580899001Considering that the current supply of native tree seedlings is not compatible with market growth projections for the coming years, the need to increase production to meet potential oration sector, environmental regularization, and possible supply to one of Pernambuco's furniture hubs. In this sense, this work aims to diagnose forest seedling nurseries in the county of Gravatá and to propose the development of a project to implement a new forest nursery in the rural area of the county. Therefore, 11 nurseries that produce and/or resell forest seedlings in the region were found to be analysed and interviewed, of which 5 agreed to respond to a questionnaire that aims to analyse their operating profiles and identify productive aspects; generating an information base for a SWOT analysis that results in an action plan, which brings an arrangement of suggestions coherent with the local reality supporting the aim of the study and substantiate the design, which was modeled using SketchUp 2019 software. The study showed that the forest nurseries present in Gravatá have a timid performance regarding seedling production, with 80% of them only resellers, making it clear that seedling production is not yet seen as a significant business in the municipality. Regarding infrastructure, the forest seedling nurseries in the municipality have basic infrastructure components. Regarding species diversity and productive capacity, there are seedlings produced and/or resold are mostly exotic species, coming from nurseries with an annual capacity of up to 10 thousand seedlings, whose main destination is local landscaping. The main problems faced were technical difficulties in cultivation and low availability of seeds. Aiming to give greater robustness to the municipality's forest nursery framework, as well the supply of potential demand for forest seedlings in the coming years are met, the project to implement a new nursery was taken as a starting point, with an annual production capacity equivalent to a total of 3,488 to 8,208 seedlings produced in bags and tubes, based on the considerations brought by the action plan generated from the analysis carried out.Item Crescimento e qualidade de mudas de Piptadenia stipulacea (Benth.) Ducke, em diferentes recipientes e doses de fertilizante misto(2024-09-12) Souza, Thallyta Valentin dos Santos de; Freitas, Eliane Cristina Sampaio de; http://lattes.cnpq.br/7525975084334972; http://lattes.cnpq.br/1375547405957419In 2022, Brazil suffered a neduction of 2.05 million hectares of native forest, the Caatinga biome, in tum, lost the equivalent of 140.637 hectares. This highlights the urgency of actions to curb environmental degradation and promote conservation. It is vital to invest in research on native forest species to fill technological gaps, meet the demand for seedlings and drive sustainable development. Piptadenia stipulacea (Benth.) Ducke, a species native to Brazil, is a recommended option for recoverins degraded areas in the Caatinga. Therefore, the objective o£ this work is to evaluate the influence of the volumetric capacity of containers for the production of seedlings such as tubes and polyethylene bags, combined with different doses of NPK, on the growth and quality of seedlings of Piptadenia stipulacea (Benth.) Ducke. The study was carried out in the forest nursery of the Forestry Science Department of the Federal Rural University of Pernambuco (UFRPE), from November 2022 to March 2023. Three containers were tested for the production of seedlings: a 120 cm3 tube, a 280 cm3 and plastic bag of 3449 cm3 (20 cm x 30 cm) and four doses of NPK (4-14-8): 0; 2.0; 4.0; 6.0 Kg/m3. The analyzes of height and diameter of the stem were monitored monthly and a destructive analysis was performed at the end of the 120 days. The results indicated that the reduction in container volume caused a decrease in dry mass, diameter and height. Increasing NPK doses had a significant effect on recipient height and stem diameter. For the robustness index, the dose of 2 kg/m3 obtained the best performance. In view of the results, the use of polyethylene bags with the addition of 2 kg/m3 of NPK is recommended for the production of jurema branca seedlings.Item Planejamento da arborização urbana: estudo de caso da Avenida Duque de Caxias, São Lourenço da Mata - PE(2024-10-01) Cravo, Amanda Clarinda de Melo; Lima Neto, Everaldo Marques de; http://lattes.cnpq.br/6791561445213969This study focused on urban tree planning along Duque de Caxias Avenue, considering its feasibility and associated costs. The objective was to evaluate the physical conditions of the road and specific challenges, following the guidelines of the Urban Tree Planting Manual of Recife. Small-sized species suitable for sidewalk widths and wire heights were selected, essential to mitigate risks and reduce seedling mortality rates. The methodology included a detailed survey of available planting spaces, identifying 179 viable intervals, albeit limited by the scattered presence of urban elements such as poles and signage boards. The results highlighted the need for 2130 seedlings to cover the planned demand, considering a mortality rate of 50%. Cost assessments from nine local nurseries revealed budgets ranging from R$ 383,400.00 to R$ 440,200.00, emphasizing the complexity and economic challenges associated with acquiring seedlings in a region with scarce available native species. Additionally, a significant gap was identified in the supply of native species seedlings in local nurseries, underscoring the importance of effective policies for urban biodiversity conservation and encouragement of local seedling production. It is concluded that integrated and participatory planning is crucial for the success of urban tree planting initiatives, actively involving local communities, government agencies, and research institutions. This approach not only contributes to improving urban quality of life but also strengthens city resilience in the face of environmental challenges. This study not only provides relevant information for the practical implementation of urban tree planting projects but also highlights the ongoing need for adaptation and innovation in urban policies to promote greener and more sustainable urban environments aligned with sustainable development goals.Item Fertilização potássica no crescimento de mudas de Eucalyptus camaldulensis Dehnh. sob limitação hídrica(2024-03-04) Luna, Andressa Cristina de; Freitas, Eliane Cristina Sampaio de; http://lattes.cnpq.br/7525975084334972; http://lattes.cnpq.br/8800788371861007The objective of this study was to evaluate the effect of potassium fertilization on the growth of Eucalyptus camaldulensis Dehnh seedlings under water limitation. The sowing was done with improved seeds of E. camaldulensis Dehnh in 80 tubes of 55 cm³ each. The seedlings were grown in full sunlight, and topdressing fertilization with macro and micronutrients, along with different doses of potassium (K), using potassium chloride (KCl) as a source, was applied. After the potassium fertilization was completed, measurements of height (H) and collar diameter (CD) were taken to standardize the seedlings according to each treatment (K dose), and they were transplanted into 5 dm³ capacity pots filled with a substrate composed of 70 % subsurface soil and 30 % commercial substrate. The treatments consisted of a factorial of two irrigation regimes (with and without suspension) by five levels of topdressing fertilization with K (0, 75, 150, 225, and 300 mg dm - ³), arranged in a completely randomized design with 4 repetitions, each pot composing a sample unit. After 15 days of transplantation, irrigation was suspended in half of the pots for 21 days, and the number of leaves (NL) was counted, along with recording visual symptoms of water stress during this period. At the end of the experiment, new measurements of height (H), collar diameter (CD), shoot dry matter (NL) were taken, growth increments were calculated, and stomatal density, chlorophyll index, relative water content, and dry matter were determined. Using the data of height (H), collar diameter (CD), shoot dry matter (SDM), root (RDM), and total (TDM), seedling quality ratios were calculated: SDM/RDM, H/CD, and Dickson Quality Index (DQI). The data were analyzed using analysis of variance (p<0.05), and those indicating significant interaction were subjected to regression analysis within the qualitative factor. Analyzing the statistical data, it was observed that potassium fertilization positively influenced the initial growth of the seedlings in all treatments, with the estimated optimum dose being 286 Kg dm -3 of K. The result of the variables with the factors of K doses and irrigation of Eucalyptus camaldulensis Dehnh seedlings showed a significant difference of 5% only for irrigation.
