Item Levantamento e classificação da toxicidade das plantas ornamentais presentes nos parques urbanos de Recife - Pernambuco(2023-05-02) Zelaquett, Danilo de Souza; Brasileiro, Hélida Maria de Lima Maranhão; http://lattes.cnpq.br/4735569144086617; http://lattes.cnpq.br/2587653841058709The presence of green areas in urban centers is essential for the well-being of the population, but many ornamental plants can be toxic. The toxic agents of plants are linked to their secondary metabolism such as oxalates, saponins, alkaloids, glycosides and terpenes. Although the number of cases of plant poisoning is small, children are the most expected. The objective of this study was to carry out a survey of toxic ornamental plants present in 07 urban parks in Recife, capital of Pernambuco, and classify them according to their degree of toxicity. For this, instruments were used to collect information and record images, taxonomic identification, classification of the degree of toxicity, description of the part of the plant related to poisoning and prevalent toxic metabolites. In the parks, 29 species of toxic ornamental plants were identified, belonging to 12 botanical families, of which species from the families Apocynaceae, Araceae and Euphorbiaceae totaled 52%. The species Mangifera indica, Sansevieria trifasciata, Plumeria rubra and Thaumatophyllum bipinnatifidum were the most common, while the plants with the highest degree of toxicity found in the parks were Duranta erecta, Lantana camara, Nerium oleander and Thevetia peruviana. In all the evaluated parks, toxic plants were found near the recreation and food areas, most of the time unidentified, and with free access to the population and animals. Thus, it is necessary that the choice of species used consider their toxic potential, that more studies are careful and that educational activities are implemented for population knowledge and the adoption of preventive measures for accidents.Item Influência de diferentes substratos no crescimento inicial de rosa do deserto (Adenium obesum forssk. Roem. & Schult)(2021-12-17) Souza, José Víctor de Melo; Bezerra, Elisangela Lucia de Santana; http://lattes.cnpq.br/4360870964749577; http://lattes.cnpq.br/8900822307167760Although it is a relatively new ornamental plant on the market, the desert rose (Adenium obesum forssk. Roem. & Schult) is the fifth most traded in Brazil. Thus, the objective of this work was to evaluate the influence of different organic substrates on the development of desert rose seedlings. For development analysis, they were cultivated in vegetable soil for 9 days until germination, after which they continued to be watered daily for another 45 days, after which 60 individuals were selected and divided into 4 treatments for the experiment, namely: S1 (control group) 100% vegetable soil, S2 50% vegetable soil + 50% compost, S3 50% vegetable soil + 50% goat manure and S4 50% vegetable soil and 50% earthworm humus. The samples were kept in a greenhouse at random for 80 days and watered with 200ml at 48-hour intervals. After dismantling the experiment, the sample's morphometric data were collected and submitted to analysis of variance (ANOVA), and the means were compared by Tukey test at 5% significance. In all results, the treatments with goat manure and earthworm humus stood out and had results well above those of the control group, with averages such as leaf area and total size about five times larger than in the other treatments. Based on the results obtained, it was found that the treatments that best contributed to the development of Adenium obesum seedlings were treatments S3 (50% vegetable soil + 50% goat manure) and S4 (50% vegetable soil + 50% earthworm humus), proving that for seedlings of desert rose Adenium obesum (forssk. Roem. & Schult) the substrate porosity has a great contribution in its development.Item Caracterização de acessos de Paspalum spp. para uso como planta ornamental na Zona da Mata de Pernambuco(2019-03-26) Formolo, Aline Küster; Loges, Vivian; http://lattes.cnpq.br/2053727463453766; http://lattes.cnpq.br/7213144424417059
