“…This finding is similar to the former study in peanut seeds [15] and chickpea grains [32], which indicated that the oxidation properties of ozone could induce the alteration of polypeptide chains in viral protein coats resulted in protein degradation [17], [33]. Other investigations also noticed that free radicals' generation due to ozone exposure brings the seed cellular damage and amino acids oxidation, implicated in protein reduction [4], [34].…”

This article describes an idea about improving the aged soybean seed quality through ozone application based on the consideration that the ozone's oxidative and reactive nature could preserve agriculture commodities during storage. Using soybean seeds that were naturally aged in room temperature storage (25±5°C) for two months, gaseous ozone's efficacy in rejuvenating the aged seeds was examined. The aged seeds were divided into three different packages: open container, polypropylene woven sack, and vacuum polyethylene plastic. Gaseous ozone at a capacity of 150 g/h was continuously exposed on packaged seeds during six months of storage under low temperature (18±5°C). The authors found that ozone in specific limit exposure could improve physiological characteristics and inhibit some chemical properties deterioration of aged soybean seeds during storage. Our technique allows for improvement in germination percentage and germination rate of aged seeds in the fourth month of ozone exposure (p<0.05). However, these physiological parameters decreased significantly in the sixth month of ozone exposure, signing that prolonged ozone exposure would lead to adverse effects due to excessive oxidation. The result also showed that ozone storage significantly retard the elevation of moisture and free fatty acid content of aged soybean seeds. The ozone effectiveness evaluation is confirmed in all packaging conditions, but the vacuum packaging offered better preservation on almost entirely seed quality parameters during storage, except for protein. This research result provides a promising technique to restore aged seed quality and can be used for better seed provision in the seed industry.

“…However, seed aging becomes a considerable constraint in soybean and other agricultural production. Its occurrence causes delayed germination, reduced vigor, and viability deprivation, leading to genetic and financial losses [3], [4]. This process could occur even under optimal storage conditions [5].…”

“…Water and temperature are the main factors that influence seed viability during storage (Bewley et al, 2013;Colville, 2017). Seeds stored with high water content and exposed to higher temperatures exhibit intense respiratory activity, which favors the accumulation of reactive oxygen species (ROS) (Ebone et al, 2019;Zhang et al, 2021). ROS cause oxidative damage to lipids, proteins and nucleic acids and accelerate the process of aging and loss of seed viability (Zhang et al, 2021).…”

ROS cause oxidative damage to lipids, proteins and nucleic acids and accelerate the process of aging and loss of seed viability (Zhang et al, 2021). In seeds stored with high water content and exposed to freezing temperatures, the loss of viability may be associated with cellular damage caused by the formation of ice crystals (Hellmann et al, 2006;Marcos Filho, 2015).…”

“…Seeds harvested with incomplete maturity and/or lower vigor show greater intensity of deterioration during storage (Marcos Filho, 2015), which may explain the fact that seeds from unripe fruits were more affected. Storage at high temperatures increases metabolic activity, consumption of reserves and oxidative stress in seeds, which intensifies the deterioration process (Ebone et al, 2019;Zhang et al, 2021).…”

The maintenance of seed viability during storage is influenced by several factors related to the species and to the environment. This work aimed to determine the viability of Mimosa caesalpiniifolia seeds from unripe and ripe fruits stored at different temperatures (ambient, 10 ºC, 0 ºC and -21 ºC). For this, the germination performance of the seeds was evaluated at 0, 3, 6 and 12 months of storage. The experimental design was completely randomized, with four replicates of 25 seeds per treatment. The variables evaluated were: number of germinated seeds, number of hard seeds, number of unviable seeds and number of normal seedlings. The storage potential of M. caesalpiniifolia seeds depends on the fruit maturity stage. Seeds from unripe fruits without drying do not tolerate storage. Seeds from unripe fruits with drying at 15% water content maintain viability, for 12 months, when stored at a temperature of 10 °C. Seeds from ripe fruits without drying maintain viability, for 12 months, when stored at temperatures of 0 °C and 10 °C.

Societal Impact StatementBroomrapes and witchweeds have devastating effects on crops in parts of Europe, Africa, and Asia. The key to their success is the production of copious, long‐lived seeds, which germinate in response to the perception of chemicals released by their hosts' roots. Here, it is proposed that the success of a parasite population will decrease as its seed bank ages due to the gradual decrease in sensitivity to the host signals in correlation with alterations of the seeds' epigenetic landscape, which is the set of non‐hard‐coded genetic information that influences gene function. This research provides important information toward a better understanding of parasite seed bank dynamics, which must be accounted for in future control strategies.Summary Broomrapes (Phelipanche and Orobanche spp.) and witchweeds (Striga and Alectra spp.) are obligate root parasitic weeds responsible for major crop yield losses worldwide. Their success in agricultural landscapes is attributable to their ability to produce thousands of long‐lived minute seeds that coordinate their germination with the presence of nearby hosts by perceiving host‐derived strigolactones. The processes underlying the alleged decade(s)‐long persistence in the field are understudied. Here, we used an accelerated seed aging method coupled with germination bioassays and an enzyme‐linked immunosorbent assay (ELISA), which allowed studying seed aging in Orobanchaceae in a comparative manner. We show that the losses of seed viability and germinability associated with seed aging are accompanied by a decrease in both strigolactone sensitivity and global DNA methylation. Our results also suggest that seeds of broomrapes are longer‐lived than those of witchweeds. Overall, this emphasizes the need for further research into how epigenetic mechanisms contribute to alterations in seed viability in parasitic weeds and how seed aging influences seed responses to their environment.
