“…Both post-harvest segregation and correct storage of hemp seed will be essential. The high oil content of hemp seed means that seed quality is likely to be influenced by storage conditions, in turn dictating downstream use that is impacted by oil oxidation and rancidity (Suriyong et al 2015 ). The protective compounds in hemp seeds which can help to stabilise the lipid profile during storage, can vary widely by cultivar, and thus shelf life will also vary (Izzo et al 2020 ).…”

Industrial hemp, with low levels of the intoxicating cannabinoid tetrahydrocannabinol (THC), is grown for fibre and seeds. The industrial hemp industry is poised for expansion. The legalisation of industrial hemp as an agricultural commodity and the inclusion of hemp seed in foods is helping to drive the expansion of the hemp food ingredients industry. This paper discusses the opportunity to build an industrial hemp industry, with a focus on the prospects of hemp seed and its components in food applications. The market opportunities for industrial hemp products are examined. Various aspects of the science that underpins the development of an industrial hemp industry through the food supply chain are presented. This includes a discussion on the agronomy, on-farm and post-harvest considerations and the various types of food ingredients that can be made from hemp seed. The characteristics of hemp seed meal, hemp seed protein and hemp seed oil are reviewed. Different processes for production of value-added ingredients from hemp seed, hemp seed oil and hemp seed protein, are examined. The applicability of hemp seed ingredients in food applications is reviewed. The design of hemp seed ingredients that are fit-for-purpose for target food applications, through the selection of varieties and processing methods for production of various hemp seed ingredients, needs to consider market-led opportunities. This will require an integrated through chain approach, combined with the development of on-farm and post-farm strategies, to ensure that the hemp seed ingredients and foods containing hemp seed are acceptable to the consumer.

“…Um dos fatores que contribui para a manutenção da viabilidade das sementes ortodoxas é a manutenção do baixo conteúdo de água e armazenamento em ambientes com baixa temperatura (Kanazawa et al, 2015;Suriyong et al, 2015). Neste estudo, apesar da grande variação da temperatura durante o ano, o conteúdo de água das sementes se manteve em torno de 10% durante todo o experimento, o que pode ter propiciado condições adequadas para a manutenção da viabilidade nas condições de campo (Motta et al, 2006;Shen et al, 2011).…”

RESUMOA capacidade que determinadas espécies têm de manter as sementes viáveis por longos períodos no banco de sementes é essencial para a resiliência ambiental, o que é utilizado na restauração florestal. Este trabalho teve como objetivo estudar o comportamento de banco de sementes induzido de P. dubium. A indução do banco de sementes foi feita em fragmento de Floresta Estacional Semidecídual. Foram utilizadas 100 amostras de copos de polietileno, compostas por 25 sementes cada. A cada dois meses, 5 amostras foram retiradas para determinação de: conteúdo de água, viabilidade, porcentagem de emergência de plântulas e porcentagem de predação. As sementes da espécie P. dubium podem permanecer por até 16 meses viáveis enterradas no solo. Esse resultado permite a classificação da espécie como formadora de banco de sementes persistente. A predação de sementes foi o principal fator para que ocorresse a redução do banco de sementes do solo.Palavras-chave: dormência, viabilidade, longevidade. Behavior of Peltophorum dubium ((Spreng.) Taub.) Seeds in a Burial Seed Bank ABSTRACTThe ability of certain species in keeping the seeds viable for long periods in the soil seed bank is essential for environmental resilience, which is used in forest restoration. This work aimed to study the behavior of a buried seed bank of P. dubium. Burial seed bank was performed in a fragment of Seasonal Semideciduous Forest. One hundred samples consisting of 25 seeds in polyethylene cups were placed under the canopy. Every two months, five samples were taken for determination of water content, viability, emergency (root protrusion and seedling formation) and predation. Seeds of P. dubium may remain buried in the ground for up to 16 months keeping their viability. This result indicates that P. dubium is able to form persistent soil seed bank. The predation was the main factor contributing to the seed bank reduction.

“…Storage conditions contribute to maintaining the quality of seeds up to the time of their use. Therefore, the ambient conditions related to high temperature, relative humidity, and seed moisture content must be observed before storage, since unfavorable conditions lead to accelerated reduction in seed longevity (Suriyong et al, 2015).…”

Millet is a species of the grass family used in cattle pastures, for hay, for silage, and in soil cover in no-tillage systems. However, studies on seed production and post-harvest techniques for this species have not been sufficiently developed, considering the demand for and potential of this crop. The objective of this study was to monitor the physiological quality of millet seeds stored in porous packaging. Millet seeds were stored under four ambient conditions (natural laboratory environment, dry chamber, refrigerator, and freezer). Physiological quality was evaluated by germination and vigor tests before and during storage each year, up to six years for the dry chamber and natural laboratory environment, and up to 12 years for the refrigerator and freezer. Analysis of variance was conducted on the data, which were in 4 × 6 and 2 × 12 (environment and storage period) factorial arrangements. The means of the environments were compared by the Tukey test (p ≤ 0.05) and the storage periods by regression analysis. The germination capacity of millet seeds is best conserved in a refrigerator and freezer, and they remain viable for up to twelve years of storage under these conditions.
