Anatomy of the floral, bract, and foliar nectaries of Triumfetta semitriloba (T...
Meira, Renata Maria Strozi Alves; Azevedo, Aristéa Alves; Araújo, João Marcos de; Silva, Kellen Lagares Ferreira; Leitão, Carlos André EspoladorTriumfetta semitriloba Jacq. (Tiliaceae) is a tropical weedy species with floral nectaries and glands located at the margins of the leaves. The objectives of this work were to describe the anatomy of these secretory structures and to analyze their exudates. Sucrose, glucose, and fructose were identified in the product released by these secretory structures, characterizing them as nectaries. The nectaries of T. ...
Rheological and physicochemical studies on emulsions formulated with chitosan p...
Soares, Lucas de Souza; Faria, Janaína Teles de; Amorim, Matheus Lopes; Araújo, João Marcos de; Minim, Luis Antonio; Coimbra, Jane Sélia dos ReisChitosan, a natural, cationic polysaccharide, may be a hydrocolloid strategic to formulate acidic food products, as it can act as both bio-functional and technofunctional constituent. Typically, acetic acid is used to disperse chitosan in aqueous media, but the use of this acid is limited in food formulations due to its flavor. In this study, chitosan was firstly dispersed (0.1% m/V) in lactic acid aqueous solu...
Effects of simulated acid rain on the foliar micromorphology and anatomy of tre...
Sant’Anna-Santos, Bruno Francisco; Silva, Luzimar Campos da; Azevedo, Aristéa Alves; Araújo, João Marcos de; Alves, Ericka FigueiredoIn order to correlate sintomatology with anatomical alterations caused by acid rain in leaves of tropical species, seedlings and saplings of Spondias dulcis Forst. F., Mimosa artemisiana Heringer and Paula and Gallesia integrifolia (Spreng.) Harms were exposed to simulated low-pH acid rain (pH 3.0). Control plants were submitted only to rain with distilled water (pH 6.0). The plants were exposed daily to the ac...
Utilização de parâmetros morfoanatômicos na análise da fitotoxidez do flúor em ...
Sant'Anna-Santos, Bruno Francisco; Duque-Brasil, Reinaldo; Azevedo, Aristéa Alves; Silveira, Alice de Souza; Araújo, João Marcos de; Aguiar, RosaneCom os objetivos de avaliar o grau de suscetibilidade e caracterizar as injúrias na morfoanatomia de folhas de Magnolia ovata, mudas foram submetidas à chuva simulada com flúor (10 µg.ml-1 de F-) por 10 dias consecutivos. No tratamento controle, utilizou-se apenas água deionizada. Folhas foram coletadas para quantificação de flúor na matéria seca e fixadas para análises em microscopia de luz e eletrônica de var...
