Strawberry is a highly perishable fruit due to postharvest pathological problems, mainly caused by Botrytis cinerea fungus. Thus, edible coatings can be a technological alternative to chemical additives in strawberry preservation, because coatings from natural sources have been considered an environmentally friendly technology, used to preserve and extend the postharvest shelf life of fruits. Therefore, the aim of this study was to evaluate the capacity of two edible coatings (sodium alginate and carboxymethyl cellulose) to keep the physicochemical and microbial quality and extend shelf life of strawberries. The produced coat was obtained from the spreading of film-forming solution on glass petri dishes and strawberries were immersed in the coating solution and stored at refrigeration temperature (2.0?4.5°C). Thermogravimetric analysis, film thickness and weight loss percentage of the coated and control samples were performed. The films exhibited thickness from 0.015 to 0.060 mm. Thermogravimetric analysis showed similar decomposition behavior for the films produced. In addition, the films showed suitable thermic stability. Weight loss percentage were not significantly diferente (p>0.05) in coated strawberries compared to the control. Edible coating prevented Botrytis sp. injuries when stored up to 5 days at refrigeration temperature. Therefore, strawberry coated presented higher microbial quality characteristics than control and it can be a potential alternative to fruit industry. Further studies should be performed to optimize the composition of films in order to preserve also thephysicochemical quality of strawberries.

The objective of this work was to identify the spectral bands, vegetation indices, and periods of the canola crop season in which the correlation between spectral data and biophysical indicators (total shoot dry matter and grain yield) is most significant. The experiment was carried out during the 2013 and 2014 crop seasons at Embrapa Trigo, in the state of Rio Grande do Sul, Brazil. A randomized complete block design was used, with four replicates, and the treatments consisted of five doses of nitrogen topdressing. Plant dry matter, grain yield, and phenology were measured. The canola spectral response was evaluated by measuring the canola canopy reflectance using a spectroradiometer, and, with this data, the SR, NDVI, EVI, SAVI, and GNDVI vegetation indices were determined. Pearson?s correlations between the spectral and biophysical variables of canola showed that the red (620 to 670 nm) and near-infrared (841 to 876 nm) bands were the best to estimate the dry matter. The vegetative period is the most indicated to obtain the most significant correlations for canola. All the used vegetation indices are adequate for estimating the dry matter and grain yield of canola. |
