    The present study aimed to determine the effect of different container volumes and doses of controlled release fertilizer (CRF) on the morphophysiological aspects of Balfourodendron riedelianum seedlings in the nursery and verify if these responses were replicated in the field. For the production of seedlings in nursery, three container volumes (180 and 280 cm³ polypropylene tubes and 500 cm³ plastic bags) and four doses of CRF (0, 4, 8, and 12 g L-1 of substrate) were tested, and the seedlings were grown for 240 days. At the end of the nursery period, the following parameters were measured: height (H); stem diameter (SD); dry mass of shoot, root, and total; root length; leaf area; and chlorophyll fluorescence. The H/SD ratio and the Dickson Quality Index were calculated. The same treatments were evaluated in the field at 540 days after planting. Survival, height, and diameter increase, aerial dry mass, leaf area, chlorophyll a fluorescence and chlorophyll index (a, b and total) were measured. Basic fertilization using CRF had a positive influence on the production of B. riedelianum seedlings. It is recommended to use a 180 cm³ tube and a dose of 12 g L-1 CRF for the production of seedlings. The results obtained in the nursery for the production of seedlings were confirmed to occur in the field

    Corymbia citriodora and Eucalyptus dunnii are species of relevant importance due to the quality of the wood and growth potential in Southern Brazil. Therefore, we aimed to identify containers and doses of controlled-release fertilizer capable of enhancing the morphophysiological quality and growth of these species in the nursery, aiming for the proper management of these inputs. The seedlings were produced in two volumes of containers (50 e 110 cm³), filled with Sphagnum peat-based substrate, mixed with different doses of controlled-release fertilizer (CRF) NPK 15-09-12 (0, 3, 6, 9 e 12 g L-1 of substrates). In addition, the morphological (height, stem diameter, leaf area, dry weight of shoot, root, and total) and physiological (chlorophyll a and b index and quantum yield of the photosystem II) attributes were evaluated. The morphological attributes proved to be suitable indicators of the quality of C. citriodora and E. dunnii seedlings, allowing to recommend the container of 50 cm³ and the doses of 9.0 g L-1 of controlled-release fertilizer for both species. At the same time, the physiological variables evaluated were not responsive to the effect of the treatments

    In this study, we sought to determine the influence of combined treatments with different types of fertilizer and inoculation of the fungus Trichoderma harzianum on the growth and physiological characteristics of young plants of Cordia americana. To this end, we adopted a completely randomized experimental design, comprising six replications in a 5 × 2 factorial scheme, to assess the effects of five different types of fertilizer applied with or without T. harzianum inoculation. At 180 days post-planting, we performed measurements of plant height, stem diameter, leaf dry mass, root dry mass, stem dry mass, total dry mass, leaf area, Falker’s chlorophyll index, and chlorophyll fluorescence. It was found that the combined application of T. harzianum and a controlled-release fertilizer or manure-based organominerals was effective in enhancing the growth of C. americana plants under conditions similar to those in the field. The use of controlled-release fertilizer as a base fertilization was found to have a positive influence on all evaluated variables and was effective in maximizing the initial development of C. americana plants. Granulated fertilizers derived from swine manure were established to promote plant growth and photosynthetic efficiency, thereby confirming their efficacy as a fertilizer for the cultivation of C. americana

    A poluição atmosférica tem aumentado em níveis preocupantes, gerando consequências danosas a saúde humana e ao meio ambiente. A chuva ácida é um fator que está atrelado à elevação do grau poluente no ar, a qual tem recebido atenção científica, devido seu possível prejuízo. Com o objetivo de aglomerar informações sobre os efeitos da chuva ácida, foi realizada uma revisão bibliográfica em artigos científicos que tratam da deposição ácida e recursos florestais. Os resultados compilados evidenciaram vários problemas decorrentes da chuva ácida: lixiviação de nutrientes; necrose; desfolhação; elevação da acidez do solo; restrição à ocorrência de fungos micorrízicos. Ficou evidente a importância de experimentos com chuva ácida simulada, pois identificam efeitos da acidez sobre as plantas. Constatou-se também que espécies vegetais são bons bioindicadores da qualidade ambiental. Portanto, é de grande importância que se esclareçam os danos oriundos da precipitação ácida sobre ecossistemas florestais, sendo que a prevenção evitará danos ecológicos e financeiros

    A quantificação do acúmulo e determinação das características do material combustível em áreas de vegetação é uma ferramenta importante para a elaboração de estimativas de risco de incêndios florestais. O objetivo do presente estudo foi quantificar os teores de biomassa do material combustível e alocação de carbono da vegetação de uma área de capoeira no campus da Universidade Federal de Santa Maria, em Santa Maria, RS. O material combustível foi coletado em parcelas de 1m², distribuídas aleatoriamente na área e classificado em duas classes de diâmetro (I - maior que 1/4” e II - menor que 1/4”). Determinou-se o percentual de umidade, teor de biomassa e o estoque de carbono alocado. A umidade foi em torno de 50% para ambas classes analisadas. A quantidade de material combustível apresentada pela capoeira totalizou 18,6 Mg ha-1, sendo que a fração de menor diâmetro representou 93% do material combustível existente na área. O carbono fixado na biomassa seca da vegetação foi d de 4,92 Mg.ha-1. Assim, evidencia-se que em caso de ocorrência de incêndio, este pode alcançar elevada intensidade e grande velocidade de propagação, sendo necessário adotar medidas preventivas. As estimativas de estoque de carbono obtidos podem ser usadas como subsídios para a elaboração de planos de prevenção de incêndios florestais em áreas de capoeira

    This study aimed to differentiate the structure and flora of tree component groups of a stretch of forest at the southern end of the Atlantic Forest biome, Rio Grande do Sul. For sampling the tree layer (diameter at breast height ≥ 5.0 cm), 18 plots of 20 m × 10 m were systematically installed. Data were analyzed according to the structure and diversity of vegetation using the agglomerative hierarchical cluster analysis method with Ward linkage, and the quadratic Euclidean distance to measure dissimilarity. The formation of three groups of flora was evident. The species composition of each group belonged to different stages of natural succession. Group I had the highest species richness (42 species) and the highest species diversity (2.92 nats ind.-1). The species with the highest importance value index (IVI) were: in Group I, Actinostemon concolor (14.7%), Trichilia claussenii (VI = 9.8%), and Apuleia leiocarpa (8.9%); in Group II, Trichilia claussenii (21.2%), Sorocea bonplandii (18.1%), and Trichilia elegans (17.6%); and in Group III, Allophylus edulis (12.1%), Cupania vernalis (9.6%), and Trichilia claussenii (9.4%). The three groups showed a negative exponential diameter distribution, common in forests with auto-regeneration capacity
