Caracterização física e química de frutos de três tipos de gravioleira (Annona muricata L.)

Abstract: Soursop fruit of types 'Morada', 'Lisa' and 'Comum' produced in the South of the state of Bahia, Brazil, were evaluated as to physical and chemical characteristics. It wasn't detected mean weight differences among the types 'Morada' (3,21kg), 'Lisa' (2,82kg) and 'Comum' (2,39kg). Fruits of 'Lisa' presented higher pulp percentage (85,85%) in relation to 'Morada' (83,57%) and 'Comum' (83,12%). The minor ratio among length and diameter observed on fruits types 'Morada' and 'Lisa', characterize them as cordiforme shape. Except the bigger value of total soluble sugars presented by 'Lisa' fruit (14,55g/100g), it was not significant the difference among soursop fruit types in respect to their chemical characteristics evaluated. which presented the following averages: oBrix 13,11; acidity 0,94 g/100g, pH 3,46 and vitamin C 37,25mg/100g. These values, except the pH, overcame the minimum values established in the Pattern of Identity and Quality of the Ministry of Agriculture, for soursop pulp.

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Abstract: Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Light affects Varronia curassavica essential oil yield by increasing trichomes frequency

Abstract: Light can act on essential oil yield directly on synthesis of secondary metabolites, or indirectly on plant growth. Varronia curassavica Jacq., Boraginaceae, is a native medicinal species from Brazil known as “erva-baleeira”, with anti-inflammatory activity related to its essential oil. Despite pharmacological evidences of this species and its economic importance for herbal medicine production, little is known about the effect of light on growth and essential oil production. This study aimed to analyze the influence of different irradiances on growth, frequency of trichomes, essential oil yield and composition of V. curassavica. The irradiance affected plant growth, but no significant alteration on leaf biomass was detected. The increase in essential oil content under higher irradiance reflected on essential oil yield, and is associated with higher frequency of glandular, globular trichomes. The essential oil composition, rich in caryophyllene derivatives was affected by irradiance, but α-humulene, the constituent of pharmaceutical interest, remained unchanged.

Fracionamento químico e físico do carbono orgânico total em um solo de mata submetido a diferentes usos

Abstract: A materia orgânica e um importante indicador da qualidade do solo, pois esta relacionada com diversas propriedades quimicas, fisicas e biologicas, sendo importante o conhecimento do teor de C orgânico total (COT), bem como de suas fracoes. Com base nisso, realizou-se esta pesquisa objetivando caracterizar e quantificar os estoques de COT e suas fracoes como indicadores da qualidade de um solo, submetido a diferentes usos: (1) Mata Atlântica, (2) Cacau (Theobroma cacao) e (3) Pastagem (Brachiaria decumbens), em uma microbacia no sul da Bahia. Para cada uso, coletaram-se amostras nas profundidades de 0-10 e 10-20 cm e procedeu-se a caracterizacao quimica e fisica do solo, a determinacao do COT e ao seu fracionamento quimico e fisico. O teor de COT nao diferiu entre os diferentes usos do solo nas duas profundidades estudadas. A percentagem de C humificado e nas fracoes de acidos fulvicos e humina foi maior na pastagem, na camada de 0-10 cm. Houve menor percentagem de C nao-humificado nos sistemas cacau e pastagem, e maior relacao C:N no sistema pastagem na camada de 10-20 cm. O sistema cacau promoveu aumento na quantidade de C orgânico na fracao leve na camada de 10-20 cm. A substituicao da mata pelo cultivo do cacau no sistema cabruca (sub-bosque) ou pela pastagem nao alterou os teores de COT e de suas fracoes na area estudada.
