Tectona grandis L.f. (teak) is an exotic forest species of economic and social importance for Brazil. The teak seeds are inserted in fruits that have hard endocarp and mesocarp of high resistance which produces a slow and irregular germination of the seeds and constitutes a limitation for the production of teak seedlings. The methods that have been used to overcome dormancy produce slow and irregular germination. The objective of this work was to evaluate methods of overcoming dormancy in teak diaspores, in order to verify the viability of the methods in the uniformization of teak seed germination. The experiment was installed in a completely randomized design, with five methods of breaking dormancy, on two different substrates, one only of washed sand and the other of sand + organic soil, where they form 10 treatments, 2 repetitions and 50 diaspores per repetition. The control treatment (T6) in sand + organic soil was the procedure that presented, in the diaspores, a germination percentage of 65% and a germination speed index of 1.40, values higher than those found in the pre-germinative treatments that were used.

This study aimed to provide structural and histochemical information about the stem of species popularly known as “stone breaker”, found in the municipality of São Mateus (ES). The species analyzed were Euphorbia prostrata Aiton., Euphorbia hyssopifolia L., Phyllanthus amarus Schumach. & Thonn and Phyllanthus tenellus Roxb. Vouchers were collected on the Campus of the Federal University of Espirito Santo and in the Sernamby neighborhood. For the analysis, cross sections were performed between the 2nd and 5th nodes, to describe the primary growth, and between the 9th and 10th nodes, for secondary growth. Tests were carried out to detect starch, chemical composition of crystals, total lipids, latex, non-structural phenolic compounds and lignin. As for anatomical analyzes, only E. prostrata presented trichomes, which are of the tector type. Only in the species of Phyllanthus crystals were observed. Euphorbia species are differentiated by the presence of laticiferous channels. Histochemical tests revealed accumulation of starch grains, showing the amyliferous sheath of P. amarus and phenolic compounds only in the epidermis of E. prostrata. Anatomical and histochemical studies are of great relevance for the knowledge and differentiation of the species known as stone breakers, and may assist in the identification of other species with the same popular name.

Brazil is considered the largest producer of sugarcane in the world, the main raw material for the production of ethanol and sugar. The objective was to evaluate the effect of inoculation of arbuscular mycorrhizal fungi in sugarcane varieties in the production of pre-sprouted seedlings. An experiment was carried out in a completely randomized design, in a double factorial 4x2, with four varieties of cane: IACSP95-5000; IAC91-1099; IACSP95-5094 and IACSP97-4039 which interacted with and without the application of arbuscular mycorrhizal fungi on the substrate, with 20 repetitions, totaling 160 experimental units. The use of the mycorrhizal fungi cocktail provided changes in the initial development of the varieties IACSP97-4039, IACSP95-5094 and IACSP95-5000. The inoculation of arbuscular mycorrhizal fungi increased the parameters of the leaf area, the weight of the root dry matter, the adaxial epidermal thickness, the abaxial epidermal thickness, the phloem diameter and the mesophyll thickness.

Babitonga Bay (BB) includes the last major mangrove formation in the southern hemisphere, being the most important estuary of Santa Catarina and including 206 islands.In order to carry out an environmental characterization of Ilha Grande (IG), of BB, field visits were performed from July 2018 to March 2020 and a bibliographic review about the island was realized. The IG is located in the central portion of BB, with an approximate area of 329,506 m2, perimeter of 2,971 m, elevation of up to 46 m, Cfa type climate, average annual precipitation of 1,874 mm and predominant northwest and east winds.The island shows four classes of land use: restinga vegetation, mangroves, exposed soil and urbanized area.The latter represents 2025% of the island’s surface (25 residences, two of which are abandoned). The vegetation includes formations of rain forest, mangrove, open field and sandbank. There were 131 sampled plant species, 39 of which are endemic to Brazil. There are 28 exotic species, of which eleven are naturalized and three are cultivated. Of the total plant species, 34 are used anthropically: ornamental (20), edible (12) and cultivated (2). The numerous ornamental gardens enrich the local flora but the presence of Pinus cf. elliottii and Eucalyptus sp. threaten the native flora.

The collection and identification of the egg parasitoid Trichogramma Westwood, 1833 (Hymenoptera: Trichogrammatidae) is the first step towards a successful application in the field. This is because, in a biological control program, it is necessary to select the parasitoid species most adapted to the cultivation and climatic conditions of the region where they will be used. Therefore, the objective of this work was to collect Trichogramma in orchards in the State of Rio Grande do Sul, aiming to identify it at the species level by the morphological method and to characterize it by the molecular method of the ITS2 region (internal transcribed space) of rDNA (Ribosomal Deoxyribonucleic Acid). The collection was carried out with traps made with micro-tuller fabric, randomly distributed in orchards. The capture occurred at all collection points. The identification resulted in Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) for all collections. The DNA fragments present in the agarose gel were around 500 bp.

Este estudo teve como objetivo levantar e descrever a avifauna do campus da Universidade Federal de Santa Catarina (UFSC) no município de Joinville, litoralnorte do estado de Santa Catarina, sul do Brasil. Foram realizadas cinco campanhas de campo, entre os anos 2010 e 2011, abrangendo todas as estações do ano e totalizando 23 dias de amostragem. A metodologia aplicada foi a busca direta por espécies (ad libitum), percorrendo quatro ambientes diferentes presentes na área de estudo. Foram registradas 174 espécies de aves, sendo 43 endêmicas do bioma da mata atlântica, seis ameaçadas de extinção e cinco quase ameaçadas (near threatened). Cada um dos ambientes presentes na área de estudo apresentou uma composição de espécies em particular. A elevada riqueza de espécies encontrada na pequena área do campus (120 ha) pode estar associada à alta diversidade regional e também à heterogeneidade ambiental do local. Destaca-se a importância da preservação de fragmentos florestais na porção nordeste do estado de Santa Catarina, em virtude da presença de espécies ameaçadas de extinção e endêmicas da mata atlântica detectadas nos remanescentes florestais na área de estudo.

Adenanthera pavonina L. é uma espécie arbórea com importância comercial por fornecer madeira de qualidade para construção, sendo também utilizada emreflorestamentos, preservação permanente e arborização urbana. Suas sementes são usadas em peças artesanais e medicamentos fitoterápicos. Diante da importância, objetivou-se avaliar a eficiência de diferentes tratamentos pré-germinativos, com vistas a identificar o mais indicado para a superação de dormência das sementes. Os tratamentos pré-germinativos testados foram: T1: testemunha, T2: escarificação mecânica com lixa n.º 80 por 20 segundos na região oposta ao hilo, T3: escarificação mecânica com lixa n.º 80 por 20 segundos na região oposta ao hilo + 20 min de embebição em água, T4: desponte com alicate na região oposta ao hilo, T5: desponte com alicate na região oposta ao hilo + 20 min de embebição em água. As variáveis analisadas foram: índice de velocidade de emergência, porcentagem de germinação, tempo médio de germinação, coeficiente de velocidade de germinação e velocidade média de germinação. Os tratamentos com escarificação e desponte não diferiram entre si estatisticamente, mas produziram resultados superiores quando comparados à testemunha, comprovando a importância e a eficácia do uso de mecanismos para superação de dormência de Adenanthera pavonina L.

This study aimed to evaluate the pathogenicity of bacteria isolated from the neem plant, Azadirachta indica (Meliaceae), on adults of Spodoptera frugiperda (Lepidoptera, Noctuidae). All evaluated bacterial suspensions were calibrated to a concentration of 5.0 x 108 cells / mL. The evaluated adults were the survivors of caterpillars that ingested corn leaves treated with bacterial suspensions. With these surviving adults, couples were formed and kept in cages. The longevity of males and females, the period of pre-oviposition and fertility, the total number of laying, fertility and fertility of the females were verified. Of the total isolates evaluated, 64.0% of them caused some adverse effect on adults, to the point of affecting one or more of the observed variables. The ingestion of bacteria by caterpillars reduced the longevity of adults, male and female. Females had a reduction in the fertile period, in the number of postures, in fertility and fertility. Only the pre-oviposition period was not affected. The Bacillus sp. Epi 9, Bacillus subtilis and Nim 10 isolates are highlighted because they affect the largest number of variables evaluated. The results obtained in this work are promising and important, as this is the first report of bacteria isolated from neem with pathogenic action to S. frugiperda.

The present study evaluated the morphology and biometry of tarumã fruits and seeds. The experiment was conducted at the Federal University of Pelotas and the fruits were collected in two matrices located in Quedas do Iguaçu – Paraná, in March 2018. The length, width and thickness of fruits and seeds were determined using a digital caliper. For biometric assessments, the arithmetic mean, standard deviation, variation coefficient and the amplitude of the values obtained were calculated. The seed germination process started in approximately 32 days. Throughout the hypocotyl, a color transition was verified. It was observed that the values of length and width of the fruits varied from 15 to 22 mm and 12 to 18 mm, respectively. Regarding the biometry of the seeds, it can be verified that the length, width and thickness of the seeds varied from 5 to 13 mm, 4 to 10 mm and 3 to 7 mm, respectively. As for morphology, it was identified that the species has germination of the epigeal type with protected cotyledon seedlings (phanerocotyledons).

Este trabalho teve como objetivo avaliar a produção de mudas de Moringa oleifera em função do manejo hídrico. O experimento foi conduzido em casa de vegetação na Universidade Federal Rural do Semi-Árido, em delineamento inteiramente casualizado, com três tratamentos: rega diária (RD), rega a cada 3 dias (R3D) e rega a cada 6 dias (R6D), com cinco mudas por tratamento. Avaliaram-se semanalmente a altura, o diâmetro e o número de folhas e, ao final do experimento, foi determinado o peso seco da folha, do caule e da raiz, assim como a alocação de biomassa foliar, caulinar e radicular, além do índice de qualidade de Dickson. Os diferentes intervalos de rega não afetaram as variáveis avaliadas, com exceção do número de folhas e a alocação de biomassa foliar, que foram reduzidos para o tratamento R6D. Em condições de viveiro, pode ser adotado o ciclo de rega a cada 3 dias, sem prejuízos no desenvolvimento da espécie em foco, ou a cada 6 dias, embora nesse caso haja perda de folhas, com benefícios ambientais e econômicos tanto para o produtor quanto para a natureza.
本研究旨在评价水管理对辣木幼苗产量的影响。试验在Universidade Federal Rural do Semi- arido的温室中进行，采用完全随机设计，分为3个处理:日浇水(RD)、3天浇水(R3D)和6天浇水(R6D)，每个处理5株幼苗。每周测定叶片高度、直径和叶片数，试验结束时测定叶片、茎和根的干重，以及叶片、茎和根生物量的分配，以及迪克森品质指数。不同的浇水间隔对评估的变量没有影响，除了叶片数和叶片生物量分配在R6D处理中减少。在苗圃条件下，可以采用每3天浇水一次的循环，而不损害重点物种的发育，也可以采用每6天浇水一次，尽管在这种情况下会有叶子的损失，对生产者和自然都有环境和经济效益。
