“…For this type of sorption isotherms, water is supposed to be adsorbed in the form of multilayers. The sorption isotherms obtain for rapeseed are in accordance with data available in literature for oilseeds (Pixton and Warburton 1971, Giner and Gely 2005, Kumar et al 2011.…”

“…About 50 g of the treated seeds were placed in microporous polypropylene bags (Cuero et al 1985). Incubation was at a relative humidity of 85% and 95% at 25 C according to Pixton and Warburton (1971). Experimental design was a completely randomized factorial (4 treatments x 6 incubation times) with four replications.…”

Phenolic compounds in peanut seeds: Enhanced elicitation by chitosan and effects on growth and aflatoxin B₁production byAspergillus flavus

et al. 1995

Effects of chitosan and Aspergillus flavus to enhance elicitation of phenolic compounds in viable peanut seeds were conducted at two water activity levels. In vitro effects of phenolic acids on A. flavus growth and aflatoxin B 1 production were also studied. Chitosan enhanced elicitation of free phenolic compounds (FPC) at Aw .85 and .95 levels. A. flavus initially decreased and subsequently increased FPC content, but bound phenolic compounds (BPC) decreased during incubation. Chitosan + A. flavus treatment caused an increase in FPC reaching a plateau between 24-48 h at Aw .85 while BPC levels increased over the same period at both Aw levels. Major free and bound phenolic acids detected were p-coumaric, ferulic and an unknown phenolic acid eluting at a retention time of 22 min. Generally, chitosan significantly enhanced elicitation of free ferulic and p-coumaric acids and bound p-coumaric acid at Aw .95. Free unknown phenolic and bound ferulic acids at Aw .85 were enhanced by chitosan. A. flavus caused

It also depends on the temperature and RH of the air, the ripeness degree of the seed, its genotype, its physical and sanitary conditions and the method by which equilibrium was obtained (Chen, 2000;Dorner, 2008).…”

-The goal of this work was to evaluate the storage effects under different temperatures, relative humidities (RH) and packaging types on the seed physiological quality and pod moisture content of Arachis pintoi cv. BRS Mandobi. The fruit of this herbaceous, perennial, leguminous species consists of an indehiscent pod containing a single seed, which is not dehulled for planting purposes. Pod samples presenting an initial 5.8% moisture content and stored under atmospheres presenting 30, 50, 70, 80 and 90% RH at 21±2 °C reached, respectively, the following equilibrium moisture content (EMC): 5.1±0.3%, 6.2±0.2%, 7.4±0.3%, 8.5±0.2% and 11.6±0.4%. Pod components (pericarp and seed) differed from one another in terms of EMC when stored under the same RH's; on an average, the pericarp EMC was 4.2% higher than that of the seed. A drastic physiological quality reduction was observed in seeds contained in pods that presented a 6.9% moisture content when storage temperature was raised from 21±2 °C to 30±3 °C. The physiological quality of seeds was preserved for a longer time in semi-permeable packages; this contributed either to maintain low EMC's or to delay reaching higher pod EMC's, depending on the RH under which they were stored.Index terms: forage peanut, hygroscopic equilibrium, seed packaging, seed quality.Longevidade de sementes de Arachis pintoi cv. BRS Mandobi armazenadas sob diferentes condições RESUMO -O objetivo desse trabalho foi avaliar efeitos de armazenamento sob diferentes temperaturas, umidades relativas do ar (URs) e tipos de embalagens (permeáveis ou semi-permeáveis) sobre a qualidade fisiológica de sementes e o teor de água de vagens de Arachis pintoi cv. BRS Mandobi. O fruto dessa leguminosa herbácea, perene, é uma vagem indeiscente contendo uma única semente que não é debulhado para fins de plantio. Amostras de vagens apresentando teor de água inicial de 5,8%, armazenadas a 21±2 °C sob 30, 50, 70, 80 ou 90% de UR alcançaram, respectivamente, os teores de água de equilíbrio (TAE) de 5,1±0,3%, 6,2±0,2%, 7,4±0,3%, 8,5±0,2% e 11,6±0,4%. Os componentes da vagem (pericarpo e semente) diferiram entre si quanto aos TAEs alcançados sob diferentes URs; em média, o TAE do pericarpo foi 4,2% superior ao da semente. Verificouse drástica redução da qualidade fisiológica das sementes contidas em vagens apresentando teor de água de 6,9% quando a temperatura local de armazenamento foi aumentada de 21±2 °C para 30±3 °C. A qualidade fisiológica das sementes foi preservada por maior tempo nas embalagens semi-permeáveis as quais possibilitaram a manutenção de níveis baixos de TAEs das vagens ou o retardamento do alcance de teores mais altos, dependendo da UR sob a qual permaneceram armazenadas.Termos para indexação: amendoim forrageiro, embalagem de sementes, equilíbrio higroscópico, qualidade de sementes.
