“…Viable seeds have the ability to break dormancy and begin germination after absorbing enough water. However, water quality varies greatly caused by degrading environments and salinization has an important effect on inhibiting germination and subsequent root elongation (Saberali and Moradi, 2017). It was reported that water uptake of tomato plants declined with increasing salinity, causing significant reductions in morphological and/or physiological parameters, stomatal density and water conductance (Romero et al, 2001).…”

Sweet sorghum (Sorghum bicolor [L.] Moench) is a potential feedstock crop in biomass energy development, and is much more resistant to saline soils than crops. Healthy seed germination is critical for the growth cycle of plants, and determines the establishment of seedlings and subsequent crop production. High salinity conditions can result in difficulty for seed germination and delays the germination period. So, screening salt-tolerant genotypes and method for healthy seed germination under salinity stress are vital to crop production and food security. Therefore, a controlled study was conducted to explore the interactive amendment effects of exogenous gibberellic acid (GA3) and salinity on seed germination process of sweet sorghum. Seeds were presoaked in different levels of GA3 water solutions (0, 144, 288, and 576 μM) and then cultivated in gradient NaCl solutions (0, 50 and 100 mM). The effects of salinity and external GA3 on seed water uptake and germination characteristics were investigated. Compared with the effects of 0 μM GA3 at 0 mM NaCl, slight salt stress of 50 mM NaCl improved the cumulative water uptake, germination and germination index, but high salinity level of 100 mM NaCl significantly inhibited these germination traits. However, either 100 mM NaCl or 576 μM GA3 had significantly negative effects on seed cumulative water uptake, cumulative germination, germination index, and length of germ and radicle. The appropriate concentration of GA3 prominently relieved salt stress and improved the seed germination of sorghum seeds, and the optimum concentration for seed germination of sweet sorghum was 288 μM GA3 at each salinity level.

“…This agrees with the findings of several scholars who reported that salinity affects plant growth and development by interrupting its metabolic processes, leads to decreased productivity. Salinity in the soil causes osmotic stress (primary effect), and later this results in cellular ions imbalance triggering ion toxicity (secondary effect) (Saberali and Moradi, 2019). The high concentrations of certain salts, including Na + , Cl − and HCO 3 − are toxic to many plant species (Safdar et al (2019).…”

Exploring cheaper and sustainable strategies for managing salt-affected soils remains crucial in irrigated areas. Many researchers recommended using gypsum as material for reclamation salt-affected soils, which are costly and unavailable for most farmers. In this study, we used biochar derived from the common materials found in the irrigated areas that are locally available and less utilized as a substitute for gypsum for sustainable reclamation of salt-affected soils. Salt-affected soils (saline, saline-sodic and sodic) and unaffected were collected from the Watari Irrigation project, Kano State Nigeria using farmers' perceptions about the salinity situations of the irrigation scheme and existing legacy map data. The biochar used for this study were made using the Typha grass, rice straw, and rice bran samples collected from the same area. Thirty-six (36) containers (plastic pots) with a diameter of 27.5cm and height of 45cm each were filled with eight-kilogram dried soils, including non-saline, saline, and saline-sodic. We measured plant height, and normalized difference vegetation index (NDVI) at interval of 14 days. Number of tillers per plant were also measured during tillering stage at interval of 14 days. Stover dry weight, grain dry weight, electrolytic leakage and proline contents were measured after the end of the experiment. The results revealed a high significant effect (p<0.01) of biochar amendments in remediating different forms of salt affected soils. Saline sodic soil was effectively managed when using Typha biochar with a mean value very close to non-saline soil. Rice straw and rice bran reduces the salinity levels particularly in sodic soil. Therefore, biochar from different source could be used in addressing salt-specific problems rather than using a uniform treatment.

“…Quite frequently, the problem of poor pasture formation begins from not using vigorous seeds that have good performance in the stress situations to which they are exposed in the initial phases of germination (Cardoso et al, 2014;Bonome et al, 2017). Salinity and water deficit are among the main stress situations that affect germination and seedling emergence in the field, especially in arid and semi-arid regions (Gupta et al, 2014;Saberali and Moradi, 2019). Responses to water restriction and to salinity are closely related and the mechanisms overlap, suggesting that in both cases, the stress is perceived by plant cells as a water privation event (Bhanuprakash and Yogeesha, 2016).…”

Analyses of germination of seeds under artificial stress conditions are tools for a better understanding of the survival and adaptation capacity of species under natural stress conditions. Therefore, the aim of this study was to evaluate the effect of priming on seed germination, on breaking of dormancy, and on the length of Urochloa brizantha seedlings under water restriction and salt stress conditions. A completely randomized experimental design was used with four replications in a 3 × 6 factorial arrangement consisting of 3 germination conditions (water, water restriction with PEG, and salinity with NaCl) and 6 treatments [five priming solutions (distilled water, potassium nitrate, spermidine, gibberellin, and sodium nitroprusside) and a control (unprimed seeds)]. The following determinations were made: seed moisture content after priming (before drying) and after drying the seeds, germination test at seven and twenty-one days after sowing, germination speed index, viability by the tetrazolium test of the seeds remaining from the germination test, and seedling length. Priming is effective in minimizing the negative effects of water restriction and salinity. Use of sodium nitroprusside as a priming solution results in a lower percentage of dormant seeds and greater germination, vigor, and plant development.
