“…In the dry cold room, the greatest percentages of moisture were observed in the third month of storage for those seeds packed in multiwall paper and black polyethylene. Bezerra et al (2004), when evaluating the physiological quality of moringa seeds during storage, found that for seeds stored in a natural environment, the water content The seeds stored in a natural environment presented the greatest reductions in germination. Within this environment, the seeds stored in paper and multiwall-paper packaging remained viable until the ninth month of storage, when from then on, a significant reduction in germination was seen (Figure 2).…”

-Sesame (Sesamum indicum L.) is one of the oldest oilseed plants used by man, and has great economic potential due to the possibilities for its exploitation in both the domestic and international markets. The objective of this work was to monitor the viability of sesame seeds stored in different environments and packaging, with a view to their conservation. The seeds were packed into paper bags, multiwall paper, black polyethylene and PETE bottles, and stored for a period of 12 months in different environments: dry cold room (10 °C and 55% RH), natural environment (30-32 °C and 75% RH), refrigerator (4 °C and 38-43% RH) and freezer (-20 °C). Every three months the water content of the seeds was determined and germination, accelerated ageing, speed of emergence index, and seedling dry weight were evaluated. The experimental design employed was completely randomised, in a scheme of split-lots, with four replications. The results showed that sesame seeds remain viable for up to twelve months when stored in a dry cold room or refrigerator, regardless of the type of packaging used. In a natural environment, the seeds remain viable for up to six months in storage. Paper packaging is the most suitable for sesame seeds stored in a freezer for up to twelve months.Key words: Storage. Germination. Conservation.RESUMO -O gergelim (Sesamum indicum L.), é uma das plantas oleaginosas mais antigas e utilizadas pela humanidade, apresenta grande potencial econômico, devido às possibilidades de exploração tanto no mercado nacional como internacional. Objetivou-se com este trabalho monitorar a viabilidade das sementes de gergelim armazenadas em diferentes ambientes e embalagens visando a sua conservação. As sementes foram acondicionadas em embalagens de saco papel, papel multifoliado, polietileno preto e garrafa pet e armazenadas por um período de doze meses em diferentes ambientes: câmara fria e seca (10 °C e 55% UR), ambiente natural (30-32 °C e 75% UR), geladeira (4 °C e 38 a 43% UR) e freezer (-20 °C). A cada três meses as sementes foram submetidas às seguintes avaliações: determinação do teor de água, germinação, envelhecimento acelerado, índice de velocidade de emergência e massa da matéria seca das plântulas. O delineamento experimental utilizado foi o inteiramente casualizado, no esquema de parcelas subsubdivididas, com quatro repetições. Os resultados evidenciaram que as sementes de gergelim permanecem viáveis por até doze meses quando armazenadas em ambiente da câmara fria e seca e da geladeira, independente do tipo de embalagem utilizada. Em ambiente natural, as sementes permanecem viáveis por ate seis meses de armazenamento. Em ambiente do freezer, a embalagem de papel é a mais indicada para o acondicionamento das sementes de gergelim por até doze meses.

O trabalho teve como objetivo avaliar o efeito de diferentes embalagens e ambientes de armazenamento na manutenção da qualidade fisiológica de sementes de Erythrina velutina Willd.. O experimento foi conduzido no Laboratório de Análise de Sementes do Departamento de Fitotecnia do Centro de Ciências Agrárias da Universidade Federal da Paraíba (CCA-UFPB), localizado no município de Areia (PB). As sementes de Erythrina velutina Willd. foram coletadas embaixo de árvores matrizes, no mesmo município e levadas para o laboratório, onde se realizou a homogeneização e acondicionamento em embalagens de papel, pano e vidro e, posterior armazenamento em condições não controladas de laboratório (±25ºC), geladeira (6 ± 2ºC) e câmara fria (4 ± 2ºC), por um período de 225 dias. Antes e após os intervalos de 45 dias foram retiradas amostras de cada embalagem e ambiente de armazenamento para avaliação das seguintes características: teor de água, emergência (porcentagem e índice de velocidade), comprimento e massa seca de epicótilo, hipocótilo e raiz das plântulas normais. O delineamento experimental utilizado foi inteiramente ao acaso com quatro repetições de 25 sementes para cada teste. As sementes de mulungu são ortodoxas e acondicionando-as nas embalagens de papel, pano ou vidro podem ser armazenadas nos ambientes de laboratório, geladeira e câmara fria, durante 225 dias sem perdas significativas na emergência das plântulas.

“…The relative humidity was controlled at 50-55% in cold storage. However, Bezerra et al (2004) found that when evaluating the physiological quality of morning seeds during storage in a natural environment, the moisture content of seed decreased slowly as the storage period progressed, while for those in a cold room, the variation in moisture content was greater. And the mean effect of packaging materials on seed moisture content was not also significant (Pr=0.8025).…”

The speed of the deterioration of oil-seeds depends on conditions of the storage environment and understanding dormancy release time is important to increase the amount and uniformity in germination. Therefore, the present study was conducted to evaluate the effect of different packaging materials and storage environments on viability and dormancy of sesame. The black sesame seed was stored in three packaging materials (woven polypropylene bag, IRRI super bag, metal bin) under two environment conditions (ambient and cold storage) for eight-month (initial storage, 2-month, 4-month, 6-month and 8-month). The effect of storage environments, packaging materials and storage durations on germination percentage, germination index, seedling vigor index I and II were significant. The moisture content decreased in the early parts of storage periods and then increased in later. The moisture content of seeds in the packaging materials increased in long storage due to the effect of seed respiration and heat accumulation in a package. Higher viability was observed in ambient storage, and in a woven polypropylene bag. Because the dormancy release was slow in low- temperature condition and the carbon dioxide concentration in the airtight package inhibited the dormancy break. It also increased during storage and the earliest fully dormancy break has occurred in six-month of woven polypropylene bag storage under ambient condition. Therefore, the germination and dormancy release of sesame were influenced by storage environments packaging materials and storage durations.
