“…T 50 for untreated seeds was 3.30 days, significantly decreasing to 2.93 and 2.63 days for hydropriming and osmopriming in mannitol respectively. Both priming treatments enhanced the behavior of seeds, both at 25 °C and 18 °C (Table 1), already observed in this species (Casenave and Toselli, 2007;Ghaderi et al, 2008). At a suboptimal temperature, M41 was more effective than H16 producing a greater reduction of T 50 .…”

“…At a suboptimal temperature, M41 was more effective than H16 producing a greater reduction of T 50 . The effects of priming on velocity of germination can be explained by the reduction in the base temperature or thermal time (Welbaum et al, 1998); in cotton, this effect has been attributed to a reduction in thermal time (Casenave and Toselli, 2007). Reductions in T 50 from 0.4 to 0.8 days induced by priming are important considering that during the sowing period of the species, one expects a reduction of 5mm/day of soil available water.…”

“…The paper rolls were placed in plastic bags to avoid evaporation and were incubated at a constant temperature of 25 °C. After 16 hours of incubation in water and 41 hours in mannitol, to reach the same state of hydration (Casenave and Toselli, 2007), the seeds were removed and dried in the air until they returned to the initial water content (7-8%) and were stored in laboratory conditions until the time of their evaluation.…”

“…In low temperature conditions, to which this species is very sensitive, hydropriming and osmopriming in mannitol allowed acceleration of germination (Casenave and Toselli, 2007;Ghaderi et al, 2008) but it is not known whether these effects remain during seed storage and if they depend on the age of the seed used. Under the hypothesis that the benefits of priming in cotton are maintained from one year to the next during storage of seeds of different age and that they depend on the used substrate, the aim of this study was to evaluate: a) if the effects of hydropriming and osmopriming in mannitol on the germination of cottonseeds are maintained during their storage, b) whether the behavior of the treated seeds in storage depend on the substrate of priming used and c) whether seeds from different harvest years (age) have a similar response.…”

The objective of this study was to evaluate: a) whether the effects of hydropriming and osmopriming in manitol on cottonseed germination are maintained during their storage; b) whether the behavior of the treated seeds -in storage-depends on the type of priming substrate used; c) whether seeds from different harvest years [age] have a similar response. The effects of 16 h of hydropriming and 41 h in mannitol were tested at 18 and 25 °C on the velocity of germination, standard germination and the vigor in cottonseeds from the 2007 and 2008 harvests, and within 0, 6 and 12 months of postpriming storage. The enhancement produced by the priming treatments used remained at least for 6 months in the case of hydropriming and 12 months for osmopriming in mannitol. The latter was more effective in increasing velocity of germination and the vigor index (CWVI). Priming enhanced the behavior in both seed lots but was more effective on the younger seeds.Key words: Gossypium hirsutum, priming, germination, vigor, year of harvest, storage.O aumento produtivo associado ao priming em sementes de algodão mantém-se durante o armazenamento?Resumo O objetivo do presente trabalho foi avaliar: (a) se os efeitos do hidropriming e do osmopriming no manitol sobre a germinação das sementes de algodão mantêm-se durante a sua armazenagem, (b) se o comportamento da armazenagem das sementes tratadas depende do substrato do priming empregado, e (c) se sementes de um ano diferente de colheita (idade) respondem de igual maneira. Os efeitos de 16 horas de hidropriming e 41 horas em manitol foram avaliados a 18 °C e 25 °C sobre a velocidade de germinação, a germinação standard e o vigor das sementes de algodão das colheitas de 2007 e 2008 e nos meses 0, 6 e 12 de armazenagem postpriming. O enhancement produzido pelos tratamentos de priming utilizados ficou invariável no mínimo durante 6 meses, no caso do hidropriming, e 12 meses, para o osmopriming em manitol. O osmopriming em manitol foi mais efetivo para aumentar a velocidade de germinação e o índice de vigor (CWVI). O priming melhorou o comportamento em ambos os lotes de sementes mas foi mais efetivo nas sementes mais novas.Palavras-chave: Gossypium hirsutum, priming, germinação, vigor, ano de colheita, armazenagem.

“…Considerable interest have focused on seed priming since it also ameliorate stress tolerance by improving the activity of antioxidant enzymes which in turn decrease the adverse effects of reactive oxygen species (ROS). Hydro priming, osmopriming (using mannitol/PEG 6000) and halopriming (using KCl/KNO 3 /Calcium salts) have been found effective for cotton seed establishment under unfavourable field conditions (Toselli and Casenave, 2005;Casenave and Toselli, 2007;Papstyliano and Karamanos, 2012;Mohammad et al, 2012).…”

This review article highlights recent advances in designing biomaterials to be interfaced with food and plants, with the goal of enhancing the resilience of the AgroFood infrastructure by boosting crop production, mitigating environmental impact, and reducing losses along the supply chain. Special attention is given to innovations in biomaterial-based approaches and platforms for 1) seed enhancement through encapsulation, preservation, and controlled release of payloads (e.g., plant growth-promoting microbes) to the seeds and their rhizosphere; 2) precision delivery of multi-scale payloads to targeted plant tissues, organelles, and vasculature; 3) edible food coatings that regulate gas exchanges and provide antimicrobial properties to extend the shelf life of perishable food; and 4) food spoilage detection based on different sensor/reporter systems. Within each domain, biomaterials design principles, emerging micro-/nanofabrication strategies, and the advantages and disadvantages of different delivery/preservation/sensing platforms are introduced and critically discussed. Views of future requirements, aims, and trends are also given based on the opportunities and challenges of applying biomaterials in the AgroFood system.
