“…However, according to [26] the priming effect may vary depending on the type of solution and concentration. In the grain sorghum culture in the present study it was verified that variations can also be influenced by the difference between the types of stress and the tolerance of the genotypes (Figure 3).…”

Tolerance to water and salt stress during germination and growth of agricultural species might have superior results when seeds are submitted to priming processes. The objective of the present study was to evaluate the use of hydropriming and hormonal priming with gibberellic acid (GA 3 ) on the tolerance of divergent genotypes of sorghum to salt and water stress during germination and seedling growth. The genotypes analyzed were cultivar BRS 330 and lineage 201420, which are the most and least tolerant to water and salt stress, respectively. Sowing was undertaken under control (no stress), water stress (−0.6 MPa), and salt stress (20 dS·m −1 ) conditions, and the seeds were subjected to the following treatments: control-no immersion; hydropriming-immersion for 2 hours in distilled water; and hormonal priming-immersion in GA 3 solutions, at concentrations of 50, 75, and 100 ppm, for 2 hours. After soaking, the seeds were dried for 24 hours at a temperature of 30˚C ± 2˚C. The variables analyzed were percentage and germination speed index, root and shoot lengths, and root/shoot ratio. The stress conditions analyzed negatively affected the two genotypes; however, the seeds that underwent priming processes improved the performance of the genotypes under salt and water stress conditions, especially when using seeds of the more tolerant genotype (BRS 330) subjected to hormonal priming at 100 ppm GA 3 concentration.

“…There are several priming methods, which have been employed so far. The most commonly used methods are osmo‐priming, soaking in a solution of osmoticum (Mahboob et al, ; Rouhi et al, ), halo‐priming, soaking in salt solution (Nawaz, Amjad, Pervez, & Afzal, ; Tian et al, ), solid matrix priming, priming using solid carriers (Khan, ; Olszewski, Goldsmith, Guthrie, & Young, ), and hydro‐priming, soaking in water (Afzal et al, ; Ahammad, Rahman, & Ali, ; Harris et al, ). This study used hydro‐priming, which is the most cost effective and practical method that needs only water to prime seeds.…”

On‐farm seed priming has been reported to improve emergence, crop establishment, and yield besides improving economic benefits in dryland agriculture. These benefits can further be improved by fertilizer micro‐dosing. The purpose of this study was to investigate the effect of on‐farm seed priming and fertilizer micro‐dosing on the agronomic and economic returns of maize (Zea mays L. var. Melkassa‐2) in semi‐arid agro‐ecological conditions in Ethiopia. The experiments consisted of four treatments: no priming and no fertilizer; no priming and fertilizer; priming and no fertilizer; and priming and fertilizer. The experiments were conducted in three locations viz., Melkassa, Ziway, and Hawassa in the central Rift Valley. Analysis of variance for each location was performed separately at p ˂ .05. Results of each location were similar over the experimentation years, and hence, there was no need for carrying out combined analysis. Regardless of fertilization, primed plants showed faster emergence; better uniform crop stands; more vigorous plants; earlier flowering; earlier harvest; and higher grain and stover yield than no primed plants. Germination was 2–3 days earlier, and flowering and maturation of primed plants were 10 to 13 days earlier than no primed plants. Average grain yield increased by 11, 8, and 6% in Melkassa, Ziway, and Hawassa, respectively, by priming over no priming. Fertilizer micro‐dosing combined with priming further improved most of the agronomic characters. Fertilizer micro‐dosing combined with priming increased the average grain yield by 75, 69, and 33% in Melkassa, Ziway, and Hawassa, respectively. The economic returns also increased in the same pattern as the agronomic responses for priming, micro‐dosing or their combination. To realize the potential of seed priming of increasing agronomic performances, future research and development efforts should focus on understanding the possible underling physiological and biochemical basis of this poorly understood process with the different priming techniques.

Seaweeds are potentially excellent sources of highly bioactive materials that could represent useful leads in the alleviation of salinity stress. The effects of presoaking wheat grains in water extract of Ulva lactuca on growth, some enzymatic activities, and protein pattern of salinized plants were investigated in this study. Algal presoaking of grains demonstrated a highly significant enhancement in the percentage of seed germination and growth parameters. The activity of superoxide dismutase (SOD) and catalase (CAT) increased with increasing the algal extract concentration while activity of ascorbate peroxidase (APX) and glutathione reductase (GR) was decreased with increasing concentration of algal extract more than 1% (w/v). The protein pattern of wheat seedling showed 12 newly formed bands as result of algal extract treatments compared with control. The bioactive components in U. lactuca extract such as ascorbic acid, betaine, glutathione, and proline could potentially participate in the alleviation of salinity stress. Therefore, algal presoaking is proved to be an effective technique to improve the growth of wheat seedlings under salt stress conditions.
