“…This behavior may be associated with the stress condition to which the product was submitted. Araújo et al (2017), when studying the quality of stored soybean grains at temperatures of 17-20, 25-27 and 30 °C, observed the occurrence of moldy grains from the first month of storage at the highest temperature, with a significant increase of fermented grains at high temperatures from the third month.…”

“…showed more significant damage, especially the eighth storage period, at 35 °C when the grain at the highest moisture content was 83.50% of damaged grains, which results in values ten times higher than recommended by the Brazilian delivery rules. Higher moisture content is associated with a higher metabolic rate and, consequently, the deterioration process of stored grains is more pronounced (Araújo et al, 2017). The storage in high temperatures and moisture contents promote the oxidative and hydrolytic rancidity of soybean oil, darkening of the grains and reduction of unsaturated fatty acids, which play an important nutritional role (Pohndorf et al, 2018).…”

Storage of soybean with high percentage of grains damaged by bugs in the crop

Bugs are pest insects that, when not adequately controlled, may cause significant losses in the soybean crop. Their damage to grains compromises delivery in the storage unit and storage success. Thus, the objective of this study was to evaluate, during storage, the effect of temperature and moisture content on soybean grain quality with high damage caused by bugs in the crop. The experiment was set in a completely randomized design with a 2 x 4 x 5 factorial design, with two moisture contents (11.75 and 13.84% (w.b.)), four storage temperatures (20, 25, 30 and 35 °C), and five evaluation periods (0, 2, 4, 6 and 8 months). The percentage of damaged/fermented, damaged, fermented, broken grains, and electrical conductivity were analyzed. It can be inferred that bug-damaged soybean grains have reduced quality when stored at higher temperatures and for more extended periods. It is not recommended to store bug-damaged grains in moisture contents of 13.84% (w.b.) at temperatures above 30 °C for longer than four months. Grains stored at 35 °C when not damaged by bugs, ferment after six months of storage. Bug-damaged grains evolve to fermented grains during storage.

“…O ideal é que as sementes sejam armazenadas em câmara fria, em uma temperatura aproximada de 10 ºC e com uma umidade relativa do ar de 50% (Giselli, 2016). Ambientes com baixa temperatura e UR controlada, favorecem a manutenção do potencial fisiológico das sementes (Nik et al, 2011;Araújo et al, 2017;Moreira et al, 2019;Ferreira;Bazzo, 2020).…”

Durante o período de pós-colheita, as sementes estão susceptíveis a diversos fatores que podem reduzir o potencial fisiológico e vigor. A taxa de deterioração das sementes é influenciada por fatores genéticos, métodos de manejo e condições de armazenamento. O experimento foi realizado na UBS (Unidade de Beneficiamento de Sementes) da Fazenda São Francisco, no municipio de Rio Verde, Goiás, Brasil. Os tratamentos consistiram na colheita de semente em: 1 - pós-precipitação, armazenadas em ambiente climatizado; 2 - pós-precipitação, armazenadas em ambiente não climatizado; 3 - pré-precipitação, armazenadas em ambiente climatizado, e 4 - pré-precipitação, armazenadas em ambiente não climatizado. Foram realizados testes para avaliação da qualidade iniciam-se com a avaliação da qualidade logo após a colheita, bimestralmente de acordo com os testes padrões para verificação da qualidade até a data de uma possível realização de plantio em condição de campo (safra 21/22), (AR (emergência em areia), TZ (tetrazólio), EA 72 h (envelhecimento acelerado 72 h), EA 48 h (envelhecimento acelerado 48 h), EA 24 h (envelhecimento acelerado 24 h) e ES (emergência em canteiro de solo). As sementes colhidas em pré ou pós-precipitação e acondicionadas em ambiente climatizado apresentaram resultados com maior vigor e viabilidade.

“…The physicochemical characteristics and technological properties of the grains directly affect their quality and commercial value (MARINI et al, 2005), but these properties are sensitive to postharvest treatment, since after harvesting, the quality acquired by the grains during production reduces progressively (CARVALHO et al, 2006). In this respect, the maintenance of the oilseed characteristics throughout storage is challenging, because besides being subject to accelerated deterioration by autoxidation processes, this type of grain goes through long storage periods to compensate for the seasonality between harvests (ARAUJO et al, 2017).…”

Chemical change during storage of crambe cultivated with application of plant growth regulators

et al. 2020

This study aimed to characterize the chemical composition of crambe grains produced with plant growth regulators in the 2014 and 2015 harvests and stored for 180 days. During crambe cultivation, two foliar sprayings were carried out with the following treatments: 1) control treatment with distilled water; 2) indole-3-acetic acid 100 mg L-1 (IAA); 3) 3-gibberellic acid P.A. 100 mg L-1 (GA3); 4) Stimulate®. After harvesting, the grains were analyzed initially and after 180 days of uncontrolled storage. We checked water content, lipids in hot extraction (HE), lipids in cold extraction (CE), proteins, acidity and antioxidant activity. The Tukey test was used to compare the averages (p<0.05) and the parameters were grouped using a multivariate clustering technique presented in dendogram. The CE and HE lipid contents were reduced after storage, whereas the protein content and antioxidant activity of the grains were not altered by storage. However, the grains that received IAA application showed an increase in the CE lipid content and their preservation after storage. GA3 application, on the other hand, reduced the protein content. Lipid contents remained constant at the end of storage, and the acidity was reduced due to the application of GA3 and Stimulate® plant growth regulators. The 180-day storage changed crambe quality and regulators can assist in preserving grain quality during storage. The CE and HE lipid content and the grain acidity were good indicators for evaluating effects.
