“…Thus, several physical alternative methods have been suggested for postharvest pest control. Among these alternative methods, low doses of gamma radiation method has advantages in inhibiting the microbial growth in food (Iqbal, ; Bhatti, Iqbal, Anwar, Shanid, & Shahid, ; Mbarki, Sadok, & Barkallah, ), remove the toxicity from textile effluents (Iqbal & Nisar, ), enhancing the germination and seedling growth of seeds (Hussain et al., ), and enhanced its shelf life (Brewer, ). Furthermore, gamma radiation up to 6 kGy maintained the oil characteristics of almond (Bhatti et al., ).…”

This study was aimed to evaluate the effect of gamma irradiation at dose levels of 0.5, 1.0, 2.0, 3.0, 4.0, and 5.0 kGy on fungal growth, free fatty acids, in vitro protein digestibility (IVPD), protein solubility, and functional properties of sorghum grains. Results indicated that radiation process enhanced the storability properties. It eliminates the fungal incidence particularly at the higher doses 4.0 and 5.0 kGy, and significantly (p < 0.05) reduced the content of the free fatty acids to the level 3.4–3.2 mg/g. Moreover, a significant increase in IVPD and soluble protein was noticed in irradiated grains as compared to non‐irradiated sample and this increased with the increase in dose; however, maximum IVPD (17.6%) and protein solubility (11.7%) were observed in sorghum grains irradiated at 2.0 kGy. On the other hand, a significant reduction in emulsion capacity was observed after radiation of grains, however, the emulsion activity and stability were stable up to 1.0 kGy. The foaming properties of the radiated sample show no significant change particular at low doses up to 2.0 kGy when they are compared to untreated samples. It can be concluded that low doses of gamma irradiation might improve the storability and quality characteristics of sorghum grains and can be used as an effective alternative postharvest method for preserving and extending the shelf life of sorghum and its products.

“…Although our study did not evaluate the germination rate in seeds irradiated with γ rays, our germination rate was greater than 90% for the Mirasol cultivar. Other researchers evaluated that the total germination rate in seeds irradiated with a γ ray source using the element 60 Co as described in the study by Hussain et al (2017) where researchers irradiated H. annuus seeds with different doses of radiation which increased the germination rate by up to 82% at 0.5 Krad 60 Co for another sunflower cultivar.…”

“…Several sources of mutation induction are used to improve the characteristics of germination, vegetative and reproductive development in plants, mainly in plant species of agricultural interest such as beans (Fontes et al, 2013), rice (Miranda et al, 2009), barley (Rozman, 2014), oats (Allayarov et al, 2023), rye (Velázquez-Martí et al, 2006), wheat (Di Pane et al, 2018), peanuts (Santos et al, 2010) and sunflower (Hussain et al, 2017). The γ radiation source is chief among them.…”

The sunflower crop (Helianthus annuus L.) presents great tolerance to heavy metals and in pre-determined doses of gamma (γ) radiation it presents gains in plant increments. This study aimed to evaluate the response to doses of γ radiation and different concentrations of toxic metals in the vegetative development of sunflower. Mirasol sunflower seeds were subjected to different doses of 241Am γ rays and concentrations of Aluminum, Cerium and Copper (mg L-1). Sunflower plants were evaluated only in the vegetative period for germination, aerial length, root length, aerial and root fresh mass, aerial and root dry mass. The doses of γ radiation promoted increases in the variables in the vegetative phase, especially for 5 and 10 minutes of exposure to γ rays. The concentrations of the toxic elements Al and Ce showed significant differences in all increments, however, doses higher than 85 mg L-1 demonstrated losses in length and mass of sunflower plants. For the Cu element, the doses did not have a significant effect, these being non-significant and the cultivar Mirasol resistant. Future studies should be carried out evaluating the reproductive phase and its gains in increasing biomass and production.

“…Low dose radiation can cause stimulatory effects on plants has been reported in many previous studies. Irradiation with low doses can enhance germination percentage of seeds (Beyaz et al, 2017;Jaipo et al, 2019), reduce the time of germination (Beyaz et al, 2016;Hussain et al, 2017) and stimulate the germination of seeds stored for long period (Boonsua et al, 2020). Seedlings from seeds irradiated with low dose can grow better than the control in terms of physiological parameters including number, weight and size of organs such as: weight and size of the whole seedling, root, plumule, hypocotyl, etc.…”

Plants induced from low dose irradiated materials such as bulbs, seeds, ... may also grow better and bloom earlier (Sax, 1955) with improved plant height, shoot number, panicle length and seed number per panicle (Maity et al, 2005), and increased number of fruit and total production (Tony et al, 2013).…”

Low-dose radiation may stimulate growth in plants in general and in mosses in particular, and thus has the potential to enhance the ability to absorb the airborne elements of mosses used in the moss bag technique by making them growth better. The effect of low-energy X-ray radiation dose on the growth of Babular indica moss was investigated through an experiment with 20 doses in the range from 1Gy to 20Gy, 1Gy-interval. The results showed that the dose from 2Gy to 16Gy improved the growth of moss compared to control sample which is non-irradiated sample, and the optimal stimulatory effect was determined at the dose of 14Gy expressed in morphological characteristics, weight of the moss in the treatments and total chlorophyll content in their phyllids. The dose 14Gy was chosen to irradiate moss which was exposed in monitoring environment. The results of analysis of concentrations of the elements deposited in the air using Total Reflection X-ray Fluorescence (TXRF) technique for irradiated moss samples, non-irradiated moss samples, and native moss samples showed that the ability to absorb the elements from the air of irradiated moss was significantly improved compared to non-irradiated moss but still generally lower compared to natural moss. The findings of this study show that low-dose (14Gy) radiation treatment of mosses is one of the promising effective solutions to improve the accuracy of the results and reflect air conditions closer to reality in the environmental monitoring by moss bag technique.
