“…In the present study, germination rate decrease under the influence of arsenic stress. This observation is very much consistent with the earlier reports (Mridha et al 2021;Mondal et al 2016;Shri et al 2009). Rice plant is very much susceptible to arsenic (Upadhyay et al 2019).…”

A short-term phytotoxicity experiment was conducted on four varieties of rice (Oryza sativa L.) under the influence of arsenic (III & V) to evaluate the impact on root and coleoptiles growth. Four varieties (GB-1, IET-4786, IET-4094, and MTU-1010) of rice were undertaken for this study with different concentrations (0, 5, 10, 25 and 50 mg/L) of arsenic (III & V). Germination along with mean daily germination (MDG), length of root and coleoptile, water holding capacity of root and coleoptiles, fresh and dry weight, arsenic accumulation, MDA and root ion leakage were evaluated. Results highlighted that the percent germination of IET-4094 and MTU-1010 varieties of rice seed over control decreased significantly (p < 0.05) with increasing concentration of both arsenite and arsenate. However, the percent germination of GB-I and IET-4786 dose not affected on the different concentration of both arsenate and arsenite. The root and coleoptile length of all the four varieties showed remarkable decreasing trend over control with increasing concentration of both arsenite and arsenate. However, more pronounced effects were observed for arsenite than arsenate. Similarly, biomass of shoot is less affected than root under different concentration of arsenite and arsenate. The variety IET-4786 and MTU-1010, accumulated lower level of arsenic and variety GB-1 accumulate higher level of MDA level in root under both arsenite and arsenate treatments. Therefore, it can be concluded that the variety IET-4786 and MTU-1010 are the suitable varieties towards phytoremediation of both arsenite and arsenate. Moreover, farmers of arsenic contaminated area are recommended to cultivate IET-4786 and MTU-1010 varieties.

“…We investigated the relationship between ions and BONB in promoting the germination of recalcitrant wasabi seeds. To increase the stability of BONB in the medium, we used sodium-based solutions with several different ions that are reported to have massive effects on seed germination 27 – 29 and compared their effects on germination. We measured the concentrations of ions in BONB solutions and observed significant changes in K + and Ca 2+ concentrations through passive and active movements of ions across the cellular membranes with help of ionic channels and proton pumps 30 .…”

Bulk nanobubbles, measuring less than 200 nm in water, have shown their salient properties in promoting growth in various species of plants and orthodox seeds, and as potential drug-delivery carriers in medicine. Studies of recalcitrant seeds have reported markedly increased germination rates with gibberellin treatment; however, neither the mechanism promoting germination nor the implication for food safety is well elucidated. In our study, recalcitrant wasabi (Eutrema japonicum) seeds treated with bulk oxygen nanobubbles (BONB) containing K+, Na+, and Cl− (BONB-KNaCl) showed significantly accelerated germination. As germination progressed, 99% of K+ ions in the BONB-KNaCl medium were absorbed by the seeds, whereas Ca2+ ions were released. These results suggest that the germination mechanism involves the action of K+ channels for migration of K+ ions down their concentration gradient and Ca2+ pumps for the movement of Ca2+ ions, the first potential discovery in germination promotion in recalcitrant seeds using nutrient solutions with BONB-KNaCl.

“…When 4.5 mM Pb was applied to lentil seeds, the germination percentage and vigor index were 67% and 83% lower than controls without Pb, respectively, and the mean germination time was 17% longer. Seed germination inhibition by other metalloids has been reported, including aluminum (Al) (Rodrigues et al 2019), arsenic (As) (Mridha et al 2021), and chromium (Cr) (Khan et al 2020).…”

Rapid synchronized seed germination is desirable to ensure seedling establishment and improve crop yield.However, abiotic stresses from drought, salinity, and heavy metals have a negative impact on seed germination.The application of silicon (Si) has emerged as a promising approach for improving seed germination, especially under unfavorable conditions. However, the mechanisms of Si action have not been systematically studied in germinating seeds under conditions of abiotic stress. Considering the potential importance of sustainable agriculture, here we review recent findings of how seeds of numerous species, including several important crops, respond to Si treatment under abiotic stress. Exogenous Si has multiple effects on embryo viability, reserve mobilization, hormone/enzyme activity, membrane integrity, antioxidant metabolism, and regulation of gene expression in seed germination.
