Urban trees provide numerous benefits to the population. However, the lack of planning for the implantation of tree plants results in recurrent problems in the urban environment. Thus, this work had as objective to elaborate the Municipal Plan of Urban Arborization in the Serra Talhada /PE city. For this, initially, a survey was made on the history of the urban arborization of the city so that, later, make a diagnosis of a neighborhood as a sample. The diagnosis of the trees was performed using a technical assessment sheet, with the following data: location, species identification, plant size, types and identification of the site, interferences, relationships and diagnosis, and diseases or pests. Still, the general assessment and actions with some immediate management when necessary. The development and behavior in the urban environment of three native species: pajeú (Triplaris garderiana Wedd.), tamboril (Enterolobium contortisiliquum (vell.) Morong) and amendoim bravo (Pterogyne nitens Tul) were also evaluated. According to information collected on the history of the urban arborization of Serra Talhada / PE, they were introduced to the city for aesthetic reasons. In the inventory of the Alto da Conceição neighborhood, there were 202 trees, among them, the most frequent species was Ficus beijamina L., an exotic tree plant, considered unsuitable for planting in urban areas. In addition, it was possible to identify conflicts with electric wiring, with 19.80% and damages of pavements, with 17.82% of the plants. The growth of pajeú, tamboriland amendoim bravo species was satisfactory and indicated for urban planting. In this way, this collected information will help in the elaboration of the Municipal Plan of Urban Arborization, to avoid future.

The gladiolus stands out among the cut flowers cultivated in Brazil, as soon as it presents ease of cultivation and rapid financial return. However, its growth and productivity can be altered as a result of changes in the meteorological elements. This study investigated the vegetative growth of the gladiolus submitted to different shading environments in Serra Talhada -PE. The experiment was conducted at the Academic Unit of Serra Talhada \UFRPE, from June 28 to September 1, in a completely randomized design in three cultivation environments, full sun (control), under black shading 70% (sombrite) and 70% thermo-reflector(aluminet). The Amsterdam variety (Gladiolus x hortullanus L), cultivated in polyethylene containers with a volume of nine liters, was filledwith soil, sand and vermiculite (2: 1: 1) and three bulbs per container. Biometric parameters were evaluated: plant height, number of leaves, neck diameter, and biomass: leaf dry mass, dry mass of the bulb and dry mass of the root. In addition, meteorological elements were monitored: air temperature, relative air humidity, radiation and wind speed. The highest values in relation to plant height occurred in the treatment with 70% shade. There was no influence of the use of the shading screens for the number of leaves, neck diameter and root dry mass. The use of the thermo -reflector provided a greater accumulation of dry mass of the leaves at the end of the experimental period and favored the process of releasing the nutritional demand of the bulbs to theaerial part, more efficiently than the other growing environments. The screens provided reduced temperature, increased relative humidity, marked reduction in global solar radiation, and reduced wind speed. RFA values were higher in the thermo-reflector environment when compared to the sombrite environment.

(Universidade Federal Rural de Pernambuco(UAST); Administração., 2011) Silva, Luzia Ferreira da
A arborização confere aumento da qualidade de vida e também resgata a harmonia entre o ser humano e meio ambiente. O projeto foi composto de diversas etapas, que foram desde o reconhecimento prévio das escolas, dos alunos por meio de conversa informal e questionário até a aplicação das atividades como pintura, caixinha de perguntas e respostas, montagem de painéis, debates, passeio, teatro e lanche durante o teatro, para desenvolver nas crianças a prática de cuidar das árvores. A avaliação de cada atividade foi gradual, conforme o desempenho dos alunos. A metodologia foi adequada para os resultados esperados de forma dinâmica com interação com o grupo. O resultado da metodologia foi notado rapidamente e a cada atividade desenvolvida os alunos despertavam o interesse pelo assunto, com perguntas e comentários sobre o que era abordado. As atividades tiveram êxito, pois o tema sobre educação e conscientização ambiental relacionada à arborização urbana não é tão abordado nas escolas. O processo de conscientização é feito em longo prazo, porém tem um resultado futuro importante para a população de uma cidade em geral.

The Sunflower (Helianthus annuus L) is an ornamental cut and vase flower that has great expression in the market, because it has an expressive beauty, shape and different color. Sunflower harvesting point is an important factor for growers, which is characterized by its stem length over 50 cm. On the other hand, there is the demand of consumers, who prefer compact plants and inflorescence that has 10 to 15 cm in diameter. Studies on the breakdown of apical dominance, through the management known as pinch in sunflower crop, are carried out so that the lateral stems reach the largest size. However, the use of phytoregulators may increase or decrease both the main and lateral stems. Given this, the work evaluated whether sunflower flowering depends on the conditions of different types of harvest management. For that, a randomized design with four treatments and five repetitions was used. The treatments were: removal of the main chapter, removal of the main chapter and application of the gibberellin growth hormone, removal of lateral shoots and spontaneous development of the plant (control). To evaluate the effect of management on plant growth were analyzed: plant height (AP), stem diameter (DH), stem length (CH), number of leaves (NF), chapter outer diameter ( DE) and beginning of flowering (IF). The evaluations of fresh and dry mass were performed before the management application with the removal of one plant in the vegetative phase and the second in the reproductive phase. At 58 days after planting (DAP), the number of lateral shoots in the treatment with main chapter removal and gibberellin application was higher than the other treatments. Plant height, leaf number and diameter did not differ significantly between treatments. The removal of the side buttons did not influence the outer diameter of the chapter. Therefore, the different types of management applied at 44 days were not sufficient to verify their influence on the flowering of the plant.

(2019) Santos, Bruna Kaline de Lima; Silva, Luzia Ferreira da; http://lattes.cnpq.br/632044953717154; http://lattes.cnpq.br/8892618369396659
Amaryllis is a bulbous plant commonly sold in pots. Among the flowering plants it has evidence for its umbellated inflorescences consisting of two to twelve flowers positioned on a smooth and hollow green scape with large flowers. However, amaryllis is not cultivated commercially in the Northeast and studies are lacking to guide production, especially for small producers. Thus, the objective of this study was to evaluate the viability of commercial cultivation of amaryllis under Pernambuco semiarid conditions. The experiment was conducted at the Serra Talhada-UAST Academic Unit of the Federal Rural University of Pernambuco-UFRPE between June and August 2019. It consisted of a 4X2 bifactor, in which 4 levels of shading (0, 30, 50 and 70 were tested). %) and two types of recipient(1.10 and 3.6 liters). The vegetative parameters analyzed were: leaf length (cm), number of leaves, number of floral leaves, diameter of the floral leaves (cm), length of the floral leaves (cm) and the reproductive parameters were: days for flower opening, number of leaves. flowers, flower crosssectional diameter (cm) and flower longevity. Data were submitted to the mean and regression test in the R statistical program. The best development of leaf length was in the 70% shading mesh and in the 3,6 liter recipient. The length of the floral scape obtained better results in the 70% shading mesh and there was no difference between the recipient volumes. There was greater uniformity in the number of days in the 70% shading mesh, with floral opening within 32 days. For the diameter of the floral scape, the flower cross-sectional diameter, the number of flowers and the number of leaves there was no statistical difference between the analyzed factors. Therefore, the commercial cultivation of amaryllis bulbs of the Minerva variety is viable in Pernambuco semiarid conditions from June to August in 70% shading mesh and in the types of recipient.
Produção de flores tropicais no município de Triunfo – PE
(Universidade Federal Rural de Pernambuco(UAST); Administração., 2011) Silva, Luzia Ferreira da
O projeto visa o conhecimento técnico para produção de flores tropical para pequenos produtores da comunidade Carro Quebrado. A produção de flores em escala comercial exige condições adequadas, entre elas, é o conhecimento mais aprofundado sobre o manejo das espécies. No início, as informações técnicas colaborarão para pequena produção de flores para suprir a demanda atual e a longo prazo atingirão toda a região. As flores tropicais são utilizadas na ornamentação para eventos, que atualmente cresce expressivamente na região, esse crescimento ocorre pela maior durabilidade das flores tropicais comparando com as flores tradicionais que tem menor duração devida a alta temperatura da região semiárida. A região semiárida dispõe de fatores climáticos que favorecem a produção de flores tropicais, entretanto, a baixa pluviosidade em alguns meses do ano, dificulta o plantio e o êxito das culturas, o que é possível ser superado por meio de técnicas e tecnologias adequadas às necessidades de cada cultura.

This study analyzed the occurrence of restoration in two areas of the Federal Rural University of Pernambuco, Serra TalhadaAcademic Unit(UFRPE/UAST) with seed Bank of the State Park Mata da Pimenteira(PEMP) by means of Nucleadoras techniques and evaluated its potential when subjected to Controlled conditions. The work is organized in two chapters. The first refers to a study developed in the field in two degraded areas of UFRPE/UAST and were evaluated the seed banks of burlap and soil and burlap of two environments of the French, in the years 2016/2017 and 2017/2018, respectively. In the first year, twenty samples of burlap were collected at a depth of 5 cm and area of 1m ², constituted ten in each area of natural environment (Serra Branca and Pimenteira) of the French and transplanted to ten parcels in two areas. In the second year, five samples of more burlap soil were collected in a 10 cm layer, distributed to ten experimental units in each degraded area. The design used in both experiments was in random blocks, in the 2 x 2 factorial model with two seed bank environments and two degraded areas with five repetitions each. They were obtained in the experiment of the burlap 49 individuals, distributed in 12 families and 25 species and, in the soil and burlap experiment, 144 individuals distributed in 37 species and 18 families, with nine species in common. There was predominance of herbaceous and greater floristic diversity in the material coming from the area of natural environment two, of the park. The second chapter consisted in the evaluation of the seed bank contained in four points of the PEMP, two in each area of natural environment (Serra Branca and Pimenteira), subjected to irrigation and conditioning in two different environments of luminosity (shading and Full sun), it was also carried out tests to distinguish the soils of the studied points, by means of tests of infiltration and determination of the density and porosity. It was verified 114 individuals distributed in 31 species and 21 botanical families, with an emergency prevalence in the portions of the material from the natural environment Zone two and under shading conditions. It was concluded that the more soiled burlap transposition presents greater viability in ecological restoration, with better results when associated with soil conservation management techniques; And under controlled conditions the seed bank of the point near the water course in the Pimenteirapresented better potential restorative, optimized by shading of 70%.

The use of alternative techniques for planting in reforestation areas in the northeastern semiarid is essential, as the region is very peculiar with low precipitation, high temperatures and low relative humidity. The practices, to increase the humidity in the planting, are still scarce, mainly with the use of hydrogel and coconut fiber. Thus, the objective of this work was to verify whether hydrogel and coconut fiber contribute to the survival and growth of native seedlings in the field. The study was carried out on a rural property close to the Itaparica dam and São Francisco river, in the municipality of Petrolândia, State of Pernambuco. Fifteen individuals of each species were selected: braúna, catingueira, aroeira do sertão, monkfish and umbuzeiro.The design used in randomized blocks, with five replications and three treatments: control, coconut fiber and hydrogel, totaling 75 experimental units. The data were subjected to analysis of variance and the means compared by Tukey's test at 5% probability and simple linear regression with the variables studied. Data collection performed every 15 days in the field, for a period of 90 days, in which plant height, crown and neck diameter were evaluated. The species responded well, with a high survival rate (93,33%). The best species in height growth: catingueira (69,30% and 59,32%) and umbuzeiro (43,86% and 60,54%), respectivament, in hydrogel and coconut fiber treatments. These results are related to good moisture retention in the soil, which favored the growth of the seedlings. The catingueira had the largest canopy diameter in the three treatments, with hydrogel being the best treatment (31,53%) and the worst for umbuzeiro (5,75%) and monkfish (4,92%). In the variable neck diameter, umbuzeiro had the best result (7,25%) in coconut fiber and in hydrogel in catingueira (6,99%). The catingueira and umbuzeiro seedlings showed better growth in the studied variables, which guarantees a good survival of the species.
