“…One example of plasticizer is the glycerol, which causes changes in the intermolecular force of the polymer chains, resulting in a less dense filmogenic matrix, enabling elongation, besides decreasing tensile strength (Tarique;Sapuan;Khalina, 2021). Lipids or surfactants are added to help fix the coating on the product whether flowers or fruits, as may facilitated adsorption and adherence (Caixeta et al, 2020). The application of cassava starch films incorporated with Mauritia flexuosa oil as a surfactant has provided some barrier properties against gases and water losses (Souto et al, 2021).…”

Different products have been tested to increase the vase life of cut flowers after harvest such as the biodegradable films. These products have been used in fruits since the application on the surface may provide the modification of the atmosphere around it, although, there is no information for flowers. The objective was to evaluate the effectiveness of cassava starch films as a postharvest product for Red Torch Ginger inflorescences. On the first experiment, different starch concentrations in the solution were tested and in the second experiment starch, concentrations with plasticizers and adjuvants were evaluated. The application of the biodegradable film in Red Torch stems acted as a barrier to the gases, as observed by their water absorption rate and the maintenance of fresh weight, maintaining postharvest quality up to Day 6. The visual quality was better in the inflorescences treated with 6% starch and in the films without additives. The use of 6% starch films led to lower contents of hydrogen peroxide and lipid peroxidation and higher levels of primary-metabolism macromolecules up to Day 6, delaying senescence and increasing postharvest durability. The addition of glycerol plasticizer to the different film concentrations improved the film resistance characteristics. It is recommended the use of films based on cassava starch at a concentration of 6%. The use of the adjuvant is not essential since it changed the film’s characteristics, leaving it less transparent and more viscous, hindering drying.

O objetivo desta pesquisa foi avaliar a eficiência de diferentes herbicidas, associados ao óleo vegetal no controle do capim-amargoso (Digitaria insularis L.) em lavouras cafeeiras. O experimento foi conduzido de julho a agosto de 2019 em lavoura cultivada com a variedade ‘Catuaí Vermelho IAC 144’ sendo utilizado o delineamento em blocos casualizados (DBC). Os tratamentos adotados foram: Controle (água), glifosato (445 g/L-1) com e sem óleo vegetal (930 g/L-1), Clethodin (120 g/L-1) com e sem óleo vegetal (930 g/L-1) e o Glufosinato sal de amônio (200 g/L-1) com e sem óleo vegetal (930 g/L-1), com 4 repetições, totalizando 28 parcelas experimentais em esquema fatorial 3 x 2 + 1 (3 Herbicidas, 2 com e sem uso de óleo) + testemunha. Os parâmetros avaliados foram os percentuais de morte do capim (0% representava ausência de dano e 100% morte completa da planta) e número médio de internódios desenvolvidos, sendo as avaliações realizadas aos 7,14 e 21 dias após a aplicação do herbicida. Os dados obtidos foram submetidos a análise de variância e, posteriormente, ao teste de Scott-Knott ao nível de 5% de probabilidade. O uso de Glufosinato sal de amônio e Glifosato associados ao óleo vegetal na dosagem de 0,5% da calda, foram os melhores tratamentos dentre os utilizados no do controle do capim-amargoso em lavoura cafeeira e não resultaram em fitotoxidez em relação ao crescimento de plagiotrópicos
