“…Moreover, accumulation of carbohydrates and proteins, such as oligosaccharides and heat-shock proteins affects the tolerance of desiccation ( Waters et al, 1996 ; Bailly et al, 2001 ). Changes in lipid content are associated with the reduction of physiological quality, and reduction in fat content indicates loss of quality during storage ( Oliveira et al, 2016 ).…”

Seeds are important materials for the restoration of globally-threatened marine angiosperm (seagrass) populations. In this study, we investigated the differences between different Ruppia sinensis seed types and developed two feasible long-term R. sinensis seed storage methods. The ability of R. sinensis seeds to tolerate the short-term desiccation and extreme cold had been investigated. The tolerance of R. sinensis seeds to long-term exposure of high salinity, cold temperature, and desiccation had been considered as potential methods for long-term seed storage. Also, three morphological and nine physiological indices were measured and compared between two types of seeds: Shape L and Shape S. We found that: (1) wet storage at a salinity of 30–40 psu and 0°C were the optimal long-term storage conditions, and the proportion of viable seeds reached over 90% after a storage period of 11 months since the seeds were collected from the reproductive shoots; (2) dry condition was not the optimal choice for long-term storage of R. sinensis seeds; however, storing seeds in a dry condition at 5°C and 33 ± 10% relative humidity for 9 months had a relatively high percentage (74.44 ± 2.22%) of viable seeds, consequently desiccation exposure could also be an acceptable seed storage method; (3) R. sinensis seeds would lose vigor in the interaction of extreme cold (-27°C) and desiccation; (4) there were significant differences in seed weight, seed curvature, and endocarp thickness between the two types of seeds. These findings provided fundamental physiological information for R. sinensis seeds and supported the long-term storage of its seeds. Our results may also serve as useful reference for seed storage of other threatened seagrass species and facilitate their ex situ conservation and habitat restoration.

“…Researchers who evaluated the physiological quality of different seeds stored under different conditions (Belmiro et al, 2010;Oliveira et al, 2012;Silva et al, 2010;Zuchi et al, 2013) also observed this fact. This is directly related to respiratory activities (Oliveira et al, 2016), and lipid peroxidation may be the most frequent cause of seed deterioration and viability loss (Abreu et al, 2013). Also, the lower the water content, the greater the amount of energy needed for the seed to come into balance with the environment.…”

The commercial exploitation of pumpkin seeds, at the flour form toasted or to the production of oil, requires knowledge about the activity of water and equilibrium moistures. This study aimed to determine the equilibrium isotherms to the pumpkin seeds and describe the dynamics of the process upon its physicochemical quality. With the static method, the equilibrium isotherms were determined for different temperatures and activities of water (0.110 to 0.885 dry basis), provided conditions by the conditioner chamber of atmosphere, with the weighing of the samples until the constant mass. The hygroscopic balance of the seeds was directly proportional to the activity of water and decreased with increasing temperature, for the same value of water activity. The pumpkin seeds maintained the water volume (0.10) at the storage conditions (relative humidity 25 %). The modified Halsey model better represented the hygroscopicity of pumpkin seeds.

“…From the results obtained it can be inferred that the ozone gas, considered to have high power of oxidation (Karaca et al, 2010;Khadre et al, 2001), the main reason to be used in disinfectant processes (Cataldo, 2008;Karaca & Velioglu, 2009;Karaca et al, 2010), did not influence the physiological quality of soybean seeds, once that oxidative processes are considered one of the main physiological quality reducer in oilseeds, such as soybean, due to free radicals formation caused by oxidation on cellular tissues and reserve components such as lipids, which are more susceptible to these effects (Oliveira et al, 2016).…”

Widely used, the seeds chemical treatment can cause physiological quality loss due to phytotoxicity that the active principles may cause. In this context, the ozone gas stands out (O3) as efficient agent biocide, however its use in the pathogens control and their effects on the seeds physiological quality are still little studied. In this context, the objective was to evaluate the ozone gas efficiency as a controller agent of plant pathogens and its effect on the physiological quality of soybean seeds. For this, seeds of two soybean cultivars were treated with ozone gas in two concentrations (15 and 25 g/m³) and in five exposure times (0, 20, 40, 60 and 120 minutes). After the treatments, the seeds quality was evaluated by tests of sanity, tetrazolium, first germination count, germination percentage, initial stand, emergence percentage, emergence speed index, electrical conductivity, accelerated aging and enzymatic activity. Six pathogens were found in seeds of soybeans evaluated, namely: Phomopsis sp., Penicillium sp., Aspergillus sp., Fusarium sp., Cercospora kikuchi and Alternaria sp. It was concluded that the sanitary treatment with ozone gas reduces the incidence of these fungi and does not compromise the physiological quality of soybean seeds.
