“…In the present study, the storage conditions maintained a moisture level of approximately 12%, which is well below the threshold for microbial activity. Barley's respiration rate under these storage conditions (moisture content of approximately 12% and temperature between 15 and 35 • C) ranges from 0.0451 to 0.5461 mg CO 2 /(kgDM day) [33]. Given the similar composition of wheat and barley, it can be inferred that the respiration rate of wheat is likely similar to that of barley.…”

“…A dry matter loss of 0.1% was considered the threshold for commercial damage to wheat, and if stored wheat is to be used as seed, the approximate limit for safe storage is 0.04% [34]. Achieving a 0.04% dry matter loss under the present study conditions would take more than 450 days [33]. The low respiration rate and consequently low dry matter loss imply that no significant changes in physical or compositional parameters should be expected during storage.…”

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.
