“…The analysis of seed respiration can be an important tool for diagnosing seed metabolism (Gao et al, 2023). In general, the embryos had more intense respiratory activity at 25 °C than at 5 °C (Table 2), which was already expected since the intense metabolic activity of these embryos when the temperature is higher has already been demonstrated (Pereira et al, 2020), as observed in corn seeds (Valle et al, 2021), which are orthodox. This result can be explained by the reduction in metabolic activity as a consequence of low temperatures, which affects enzymatic action (Ruelland and Zachowski, 2010).…”

The modification of atmosphere composition is a strategy to prolong the storage of organisms susceptible to senescence. Atmospheres with high levels of carbon dioxide could be applied to prolong the viability of recalcitrant seeds, which are in a constant process of deterioration due to intense metabolic activity. However, there is a need to develop methods that allow the standardized generation of these modified atmospheres to isolate the effect of low oxygen from high carbon dioxide. In this study, the generation of modified atmospheres was carried out by experiments with insufflated gas (IG) or compensated vacuum (CV), on recalcitrant Inga vera embryos as an experimental model. In IG, CO2 and N2 were uninterruptedly injected into a mixing chamber, in which the gases underwent turbulence to be homogenized and subsequently applied to the flasks where the embryos were incubated. In CV, the embryos were placed in flasks, from which a fraction of the air present inside was removed, and subsequently, the gases of interest were injected in defined fractions. The CV method proved to be more efficient and it was possible to restrict the respiratory metabolism of the Inga vera embryos by reducing respiration with the increase in carbon dioxide applied exogenously.

“…There was a slight tendency for higher readings in the colored bags, approximately 2 percentage points higher, which could be attributed to increased biological activity resulting from the higher temperature in the peripheral layer (Table 2). As storage continued into winter and the temperature of the stored grain decreased (Figure 2), the respiration rate declined [37], resulting in a lower equilibrium CO 2 concentration of approximately 3-5% by the end of June. A previous study reported similar CO 2 concentration values in wheat silo bags rated as being in good condition [38].…”

Over the past two decades, the silo bag system has gained popularity for storing grains and by-products under hermetic conditions. However, the impact of higher temperatures in the outer grain layer on key industrial parameters, such as wheat baking quality, remains insufficiently understood. Traditional silo bags are black on the inside and white on the outside to reflect sunlight, but colored bags, recently introduced to the market, absorb more heat, potentially warming the grain and causing damage. This study aimed to assess the effect of grain strata and bag color on grain temperature and quality under field conditions. Results showed a significant surface temperature increase in colored bags compared to white ones, approximately 3 °C, which affected the temperature of the peripheral grain layer. Moisture content slightly increased (0.2 percentage points) in the outer grain layer. However, many industrial quality parameters (protein content, P/L, W, and loaf volume) and the germination test for wheat, showed no significant differences between colored and white bags or between different strata after 120 days of storage, although the falling number increased and wet gluten decreased. These findings suggest that, despite surface temperature differences, the overall industrial quality of wheat remains unaffected by external bag coloration. The influence of ambient temperature on the peripheral layer was estimated to affect approximately 5–10% of the grain mass, indicating that adverse impacts on grain quality may go unnoticed without implementing stratified sampling techniques.

“…High-vitality seeds emerge neatly, rapidly, robustly, and are resistant to various adverse environmental stresses. , In the actual process of agricultural production, seed vitality is a more sensitive index than the germination rate, which is more suitable to reflect the seed quality . Therefore, classifying seeds based on their vigor test results is of great importance to agricultural production. − The intensity of oxygen (O 2 ) consumption and carbon dioxide (CO 2 ) production during seed aerobic respiration reflects the level of seed metabolism. , Therefore, it is highly significant to monitor the concentration of O 2 or CO 2 in real time during seed respiration to comprehend the physiological and biochemical processes of seed vigor and seed germination.

A highly sensitive photoacoustic detection system using a differential Helmholtz resonator (DHR) combined with a Herriott multipass cell is presented, and its implementation to sub-ppm level carbon dioxide (CO2) detection is demonstrated. Through the utilization of erbium-doped optical fiber amplifier (EDFA), the laser power was amplified to 150 mW. Within the multipass cell, a total of 22 reflections occurred, contributing to an impressive 33.6 times improvement in the system sensitivity. The normalized noise equivalent absorption coefficient (NNEA) was 8.64 × 10–11 cm–1·W·Hz–1/2 [signal-to-noise ratio, (SNR) = 1] and according to the Allan variance analysis, a minimum detection limit of 500 ppb could be achieved for CO2 at 1204 s, which demonstrates the long-term stability of the system. The system was applied to detect the respiration of rice and upland rice seeds. It is demonstrated that the system can monitor and distinguish the respiration intensity and respiration rate of different seeds in real time.
