1 recurso en línea (páginas 514-520).Entre los factores que contribuyen para un correcto desarrollo inicial de las plantas, está el sustrato utilizado, por tanto, el objetivo del presente estudio fue evaluar el efecto del sustrato en la formación inicial y morfología de las raíces de dos especies de maracuyá. El experimento fue realizado en vivero con polisombra de interceptación luminosa (60%), en la Universidad Federal de Goiás (UFG), Regional Jataí, Brasil. Los materiales utilizados fueron maracuyá (Passiflora edulis f. flavicarpa) y el cultivar FB 200 (Flora Brasil). Se utilizaron semillas de frutos recolectados del huerto experimental de la UFG. Se sembraron en tres tipos de sustratos: Suelo I (mezcla de 2 partes de suelo + 1 parte de gallinaza + 1 parte de arena), Suelo II (suelo de barranco) y Bioplant®; se utilizó bolsas perforadas para plántulas con capacidad de 1,5 L. El diseño experimental utilizado fue completamente aleatorio con seis tratamientos, ocho repeticiones y cuatro plántulas por parcela. Después de 30 días de siembra, se evaluó: peso fresco de la raíz, peso seco de raíz y morfología de la raíz. El sustrato tuvo efecto en el desarrollo inicial de las plantas de maracuyá, donde se obtuvo los mejores resultados con Bioplant®. Este sustrato sobresalió en todas las características evaluadas mostrando su potencialidad en la propagación de esta especie.Among the factors that contribute to better initial development of plants, it is the substrate used. Therefore, this study aimed to evaluate the effect of substrate in initial formation and morphology of the roots of two species of passion fruits. The analyses were done in the nursery of the Federal University of Goiás (UFG), Regional Jataí, Brazil, with a light interception of 60%. The material used were seeds of yellow passion fruit (Passiflora edulis f. flavicarpa) and the cultivar FB 200 (Flora Brasil), harvested in the UFG experimental field. They were sown in three types of substrates: Soil I (mixture of soil, chicken manure and sand in a ratio of 2:1:1 by volume), soil II (steep bank), and Bioplant®, using for plants perforated bags with a capacity of 1.5 L. The experimental design was a completely randomized design with six treatments, eight replications and four plants per plot. After 30 days of sowing, fresh matter of root, root dry matter and morphology were evaluated. The substrate affected the initial development of yellow passion fruit, obtaining the best results with Bioplant®, showing as promising for the development of all the evaluated characteristics.Bibliografía: página 52

Enzymatic Activity in Different Crop Succession Systems in the Cerrado Region

The enzymatic activity of soil arylsulfatase and β-glucosidase enzymes are biological parameters used to measure the biological activity of soils, an important tool for identifying disturbances in agricultural systems, as they are more sensitive to differentiate changes in soil management when compared to physical and chemical attributes. Thus, the aim was to evaluate arylsulfatase and β-glucosidase levels in different succession systems. Soil samples were collected in agricultural areas with 5 years of experimentation, with four treatments: (1) soybean/corn + brachiaria (Urochloa ruzizienses), (2) soybean/corn, (3) soybean/brachiaria (Urochloa ruzizienses) and (4) soybean/millet. Routine chemical analyses were performed, and the determination of β-glucosidase and arylsulfatase was carried out according to the p-nitrophenyl colorimetric method. As a result, both enzymes presented higher average values in treatment 3. In the biological IQS, treatment 3 differed from treatments 1 and 2. Under the study circumstances, the use of soil with soybean, corn, millet and brachiaria crops provided adequate sustainability conditions, providing high arylsulfatase and β-glucosidase levels

Chlorophyll content and degrees day accumulation in passion fruit species in the Southwest of Goias, Brazil

Brazil is considered the world’s largest passion fruit producer, which benefits the entire crop chain of production and generates demand for production. The aim of this study was to evaluate the growth, thermal requirements and leaf morphological aspects of passion fruit species. The experiment was conducted at the Federal University of Goias (UFG)- Jataí, evaluating the following characteristics: leaf area, chlorophyll content (TCC) and thermal accumulation, being expressed in days after planting. To determine the total chlorophyll content, assessments were made in the middle third of the leaf blade, evaluating the accumulation of thermal units until flowering, from the average temperatures of the region. The daily temperature data were obtained from the meteorological station of the UFG - Jataí (17º53’08” S and 51º40’12” O). The cultivar FB 200 and Maracujazeiro-azedo presented higher leaf area, having the last one higher chlorophyll content in leaves and FB 200 presented lower demand in thermal units accumulation, proving its precocity

NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data
