“…This is because the cotyledons are a source of stored lipids, and was deemed undesirable to study polar lipid changes and lipid peroxidation in a tissue that contained considerable quantities of nonmembrane lipids. It has long been suggested that lipid peroxidation (or autoxidation) is increased during storage (Sharma et al 2011) and is a primary cause of seed deterioration. Major peroxidation damage occurs during storage (Stewart and Bewely 1980), but only when high RH initiates imbibition process.…”

Soybean seeds were exposed to gamma radiation (0.5, 1, 3 and 5 kGy), static magnetic field (50, 100 and 200 mT) and a combination of gamma radiation and magnetic energy (0.5 kGy+200 mT and 5 kGy+50 mT) and stored at room temperature for six months. These seeds were later subjected to accelerated ageing treatment at 42°C temperature and 95-100 % relative humidity and were compared for various physical and biochemical characteristics between the untreated and the energized treatments. Energy treatment protected the quality of stored seeds in terms of its protein and oil content . Accelerated aging conditions, however, affected the oil and protein quantity and quality of seed negatively. Antioxidant enzymes exhibited a decline in their activity during aging while the LOX activity, which reflects the rate of lipid peroxidation, in general, increased during the aging. Gamma irradiated (3 and 5 kGy) and magnetic field treated seeds (100 and 200 mT) maintained a higher catalase and ascorbate peroxidase activity which may help in efficient scavenging of deleterious free radical produced during the aging. Aging caused peroxidative changes to lipids, which could be contributed to the loss of oil quality. Among the electromagnetic energy treatments, a dose of 1-5 kGy of gamma and 100 mT, 200 mT magnetic field effectively slowed the rate of biochemical degradation and loss of cellular integrity in seeds stored under conditions of accelerated aging and thus, protected the deterioration of seed quality. Energy combination treatments did not yield any additional protection advantage.

“…The accumulation of MDA is associated with lipid peroxidation as a result of the attack of ROS on polyunsaturated fatty acids, leading to seed deterioration and reduced viability (El-Maarouf-Bouteau, Mazuy, Corbineau, Kumar et al, 2015). The accumulation of MDA during ageing is reported in several species, including sunflower (Kibinza et al, 2006), wheat (Lehner et al, 2008), cotton (Goel et al, 2003), and soybean (Sharma et al, 2013), during artificial and natural ageing. Despite these observations, Kibinza et al (2006) also observed a reduction in MDA content in sunflower seeds stored at low moisture content and concluded that seed deterioration was not associated with lipid peroxidation under those conditions.…”

“…Malondialdehyde (MDA) content is considered a biomarker of oxidative damage (Bailly et al, 1996) and is a commonly used method for the determination of lipid peroxidation (Cai et al, 2011); the accumulation of this compound is observed in the deterioration of lipid-rich seeds of some species, such as cotton (Goel, Goel, & Sheoran, 2003), sunflower (Kibinza, Vinel, Côme, Bailly, & Corbineau, 2006), and soybean (Sharma, Kaur, Bansal, & Gill, 2013).…”

ABSTRACT. The objective of the present work was to investigate the antioxidant enzyme activities and the occurrence of lipid peroxidation during storage of J. curcas seeds obtained from fruits at different maturity stages. Seeds extracted from fruits collected at three stages of maturity were used, i.e., yellow, brownish-yellow, and brown (dry fruits). The seeds were subsequently stored for 18 months in Kraft paper bags in a laboratory environment. Initially as well as every three months, the seeds were evaluated for germination and electrical conductivity, and the seed embryos were evaluated for lipid peroxidation; protein content; and superoxide dismutase, peroxidase, and ascorbate peroxidase enzyme activity at the same time points. In general, the seeds from the three stages of fruit maturity did not differ regarding germination throughout the entire period of storage, although a reduction in viability was observed after nine months of storage. The electrical conductivity increased during storage and was greater for the seeds obtained from brown fruits. There was a reduction in protein content and in enzyme activities in the seed embryo, except for superoxide dismutase. No relationship was observed between reduction in seed viability and lipid peroxidation. Thus, J. curcas seeds with high initial quality can be stored under environmental conditions for up to 9, 15 and 15 months for brown (dry), yellow and brownish-yellow fruits, respectively, without a significant reduction in germination but with a reduction in seed vigour.Keywords: physic nut, seed maturation and deterioration, enzyme activity, malondialdehyde content.Peroxidação de lipídios e enzimas antioxidativas em sementes de Jatropha curcas L. armazenadas em diferentes estágios de maturação RESUMO. O objetivo do presente trabalho foi avaliar a atividade de enzimas antioxidativas e a peroxidação de lipídios durante o armazenamento de sementes de J. curcas em diferentes estádios de maturação. Foram utilizadas sementes extraídas de frutos colhidos com coloração externa da casca amarela, amarela-marrom e marrom (frutos secos). As sementes foram armazenadas por 18 meses, em embalagem de papel Kraft em ambiente de laboratório. Inicialmente e a cada três meses, as sementes foram avaliadas quanto à germinação e condutividade elétrica, e os embriões das sementes foram avaliados quanto a peroxidação de lipídios, conteúdo de proteínas e atividade das enzimas superóxido dismutase, peroxidases e peroxidase do ascorbato. Em geral, as sementes dos três estádios de maturação dos frutos não diferiram quanto à germinação durante todo o período de armazenamento, embora tenha sido observada uma redução da germinação a partir de nove meses de armazenamento. Houve redução no conteúdo de proteína e na atividade das enzimas antioxidantes no embrião das sementes dos três estádios de maturação, com exceção da superóxido dismutase. Não foi observada relação entre a redução da viabilidade das sementes e a peroxidação de lipídios. Sementes de J. curcas com elevada qualidade inici...

“…For instance, oil content may influence seed longevity. According to Sharma et al (2013), soybean seeds from basal positions showed more deteriorative changes during storage than those from apical positions, which might be related to the higher lipid content in seeds from the basal portion of the soybean stem axis than in those from the apical portion. It is believed that lipid peroxidation is the main cause of seed deterioration in dry seeds during storage, which in turn influences longevity (Bewley et al, 2013).…”

The objective of this work was to evaluate the longevity of Astronium fraxinifolium Schott seeds collected in the states of Goiás and Minas Gerais in Brazil and analyse its association with local weather conditions during the vegetative and reproductive phases (temperature, precipitation and altitude) and seed oil content. Longevity was tested in a controlled ageing test at a constant temperature of 45 °C and relative humidity (RH) of 60, 65 or 70%, followed by germination. Seed longevity was inferior in seeds collected in the state of Minas Gerais and superior in seeds collected in the state of Goiás. There was a significant positive correlation between seed longevity and temperature and a significant negative correlation between seed longevity and altitude. No correlation was found between rainfall and seed longevity. In addition, we found a significant negative correlation between seed longevity and oil content, which was associated with an increase in malondialdehyde (MDA) content. Thus, the influence of the maternal environment during seed production should be considered during seed collection for improved ex situ conservation of A. fraxinifolium seeds.A longevidade de sementes difere em Astronium fraxinifolium Schott de duas regiões geográficas do Brasil RESUMO: O objetivo deste trabalho foi avaliar a longevidade de sementes de Astronium fraxinifolium Schott coletadas nos estados de Goiás e Minas Gerais, no Brasil, e analisar a associação com as condições climáticas locais (temperatura, precipitação e altitude) e teor de óleo da semente. A longevidade foi testada através de um teste de envelhecimento controlado a uma temperatura constante de 45 °C e umidade relativa (UR) de 60, 65 e 70%, seguido de germinação. A longevidade das sementes foi inferior nas sementes coletadas no Estado de Minas Gerais e superior nas sementes coletadas no Estado de Goiás. Houve correlação significativa e positiva da longevidade das sementes com a temperatura e correlação significativa e negativa com a altitude. Não foi encontrada correlação entre a precipitação e a longevidade das sementes. Além disso, encontramos uma correlação significativa e negativa da longevidade das sementes e do teor de óleo, que foi associada a um aumento no conteúdo de malonaldeído (MDA). Assim, a influência do ambiente materno durante a produção de sementes pode ser considerada durante a coleta de sementes para melhor conservação ex situ de sementes de A. fraxinifolium.Palavras-chave: conservação ex situ; precipitação; armazenamento de sementes; temperatura Seed longevity differs in Astronium fraxinifolium Schott from two geographic regions in Brazil Rev.
