Abstract: The concentration of CO2 in the atmosphere has been increasing significantly since the Industrial Revolution. Because of the potential impacts of the increase in CO2 from the air on the various pathosystems, assays were carried out in a controlled environment to check the effects of elevation of the concentration of CO2 from the air on Cylindrocladium candelabrum in detached leaves and seedlings of Eucalyptus urophylla. In three trials, detached leaves were wrapped in plastic trays with foam moistened with concentration of 607 ± 86, 705 ± 105, 855 ± 152 and 1101 ± 305 micromol mol-1 CO2 from the air, sprayed with conidia of the pathogen (2 × 105 conidia ml-1) and maintained at 28 ± 1.7 oC and photoperiod of 12 h for 21 days. It was evaluated the severity of leaf spot and the sporulation of the pathogen. In both experiments with seedlings of eucalyptus, the seedlings were grown in plastic tubes, kept in plastic boxes containing vermiculite at the bottom and kept in concentrations of 451 ± 35 (control), 645 ± 118, 904 ± 116, 1147 ± 216 micromol mol-1 CO2 per 30 days for acclimatization. After this period, the seedlings were sprayed with conidia of the pathogen and kept on the same conditions for six days. It was evaluated the incidence of lesioned leaves, leaf spot severity and the number of leaves containing spores of the pathogen. The height of the seedlings, the diameter of the stem and the weight of the dry matter of the aerial part and root were also evaluated. In the tests with detached leaves, the increase of CO2 concentration had no effect on the severity of leaf spot and sporulation of the pathogen. In seedlings, the elevation of CO2 concentration decreased the incidence of leaves lesioned, the severity of the disease and the number of leaves containing spores of the pathogen when compared to the control.

Organic acids and sugars are related to the chemical balance of wines and grape juices, besides exerting a strong influence on the taste balance and sensorial acceptance by consumers. The aim of this study was to validate a method for the simultaneous determination of sugars and organic acids in wines and grape juices by highperformance liquid chromatography (HPLC) with refractive index detection (RID) and diode array detection (DAD) and to characterize commercial products from northeast Brazil. The method provided values for linearity (R > 0.9982), precision (CV% < 1.4), recovery (76–106%) and limits of detection (0.003–0.044 g L?1 ) and quantification (0.008–0.199 g L?1 ) which are considered acceptable for application in the characterization of these types of matrices. Principal components analysis (PCA) was used to verify the applicability of the method in the quality control of the products and resulted in the correct separation of the samples according to their type of processing. The results obtained in the characterization of the samples studied showed high levels of glucose and fructose in grape juice and the organic acids content was similar to those found in products originating from other regions around the world.
