“…Nevertheless, a short time exposure was most beneficial. Similarly, Sudhakar et al [61], Abeli et al [70], Avdeeva et al [71], and Rodrigues et al [72] elucidated the positive impacts of low concentrations of O 3 on the germination and seedling parameters of tomato, alpine, wheat, and soybean, respectively.…”

The harmful impacts of ozone (O3) on plant development and productivity have been excessively studied. Furthermore, the positive influences of its low concentrations still need to be explored further. The present study was performed to assess the impact of low concentrations of O3 on two sweet pepper hybrids under cold stress. The ozonated water was utilized for seed soaking or foliar application at concentrations of 0, 10, 20, 30, and 40 ppm. Seed soaking using ozonated water for 1 h was compared to soaking in distilled water as a control. Moreover, exogenously ozonated water was sprayed thrice at three-day intervals compared with untreated control. The differences between the applied methods (seed soaking and foliar application using ozonated water) were not statistically detected in most of the evaluated parameters. On the other hand, the evaluated hybrids displayed significant differences in the studied parameters, with the superiority of the Lirica evident in most germination and seedling growth parameters. Both applied methods significantly improved germination and seedling growth parameters. In particular, the concentration of 40 ppm displayed the highest enhancement of the germination index, coefficient velocity, and seedling quality. In addition, it promoted the seedling maintenance of high relative water content (RWC), chlorophyll, proline, and ascorbate peroxidase activity under cold stress conditions. Moreover, it protected the cell wall from damage by decreasing membrane permeability (MP). Generally, the best results were obtained from 40 ppm followed by 30 ppm of O3 as seed soaking or foliar spray. The results pointed out the possible use of O3 in a low concentration to protect the plants from cold stress during germination and early plant growth.

“…After 10 weeks of growth, the shoot and root biomass, root length, and stem diameter of the plants treated with 2.66 and 3.96 mg L -1 significantly increased. Rodrigues et al (2019) found that ozone exposure at a concentration of 25 g m -3 for 120 minutes had no effect on the physiological or biochemical processes of cultivar soybean seeds. According to Mohammad et al (2019), ozonizing at 5 mg L -1 for 20 minutes had no negative effects on the size, color, or germination percentage of alfalfa sprouts.…”

The increasing population has led to the widespread adoption of hydroponics. Hydroponic production of fresh green forage requires minimal space, does not use soil, and allows for rapid harvesting. A fully controlled sprouting room can yield a substantial amount of green fodder from a small area with less water consumption. This study aims to investigate the effectiveness of ozone on seed germination, seedling growth, and microbial sterilization during germinated barley processing. Additionally, the sterilization of the barley sprouting room was conducted using ultraviolet and infrared light, which provides optimal sprouting conditions.The study comprises three experimental variables: three levels of ozonized water (13, 26, and 39 mg L-1) combined with three light sources (fluorescent, infrared, and ultraviolet) and three light duration times (8, 16, and 24 h). The measurements include shoot length, fresh yield weight, dry yield weight, conversion factor, chlorophyll content, N, P, K, crude protein, ash, and log reduction.The results indicated that the maximum values were observed when using ozonized water at 39 mg L-1, Ultraviolet LED as a light source, and a sterilizing medium with a light duration time of 24 h. Conversely, the minimum values were observed when using ozonized water at 13 mg L-1, fluorescent LEDs as a light source, and a light duration time of 8 h. Based on the findings, it is highly recommended to utilize the developed sprouting room throughout the year for the production of fresh forage.

“…Peanut seeds increased ethylene production during after-ripening to relief dormancy [34]. Dormancy loss during after-ripening in sunflower seeds was correlated with a reduction in sensitivity to abscisic acid (ABA), an inhibitor of germination [35]. During after-ripening, wheat seeds became sensitive to treatment with gibberellin (GA), which promoted germination, and then became insensitive to ABA [15].…”

Ozone is widely used to control pests in grain and impacts seed germination, a crucial stage in crop establishment which involves metabolic alterations. In this study, dormancy was overcome through after-ripening (AR) in dry barley seed storage of more than 4 weeks; alternatively, a 15-min ozone treatment could break the dormancy of barley immediately after harvest, with accelerated germination efficiency remaining around 96% until 4 weeks. Headspace solid-phase microextraction (HS-SPME) and liquid absorption coupled with gas chromatography mass spectrometry (GC-MS) were utilized for metabolite profiling of 2-, 4- and 7-day germinating seeds. Metabolic changes during barley germination are reflected by time-dependent characteristics. Alcohols, fatty acids, and ketones were major contributors to time-driven changes during germination. In addition, greater fatty acids were released at the early germination stage when subjected to ozone treatment.
