“…It is well known that K is an important osmoticum and it has a key role in maintaining turgor during radicle cells elongation. Thus, germination percentage, rate index, coefficient and seedling vigor indexes were increased after 50 mmol L −1 KNO 3 priming in maize plants as a consequence of a low Na/K ratio [79]. An enhanced expression of the proline synthesis gene P5CSA was observed after this seed osmopriming, improving Brassica napus germination under salt stress.…”

Seed is the dissemination unit of plants initiating an important stage in the life cycle of plants. Seed development, comprising two phases: embryogenesis and seed maturation, may define the quality of sown seed, especially under abiotic stress. In this review we have focused on the recent advances in the molecular mechanisms underlying these complex processes and how they are controlled by distinct environmental factors regulating ion homeostasis into the seed tissues. The role of transporters affecting seed embryogenesis and first stages of germination as imbibition and subsequent radicle protrusion and extension were revised from a molecular point of view. Seed formation depends on the loading of nutrients from the maternal seed coat to the filial endosperm, a process of which the efflux is not clear and where different ions and transporters are involved. The clear interrelation between soil nutrients, presence of heavy metals and the ion capacity of penetration through the seed are discussed in terms of ion effect during different germination stages. Results concerning seed priming techniques used in the improvement of seed vigor and radicle emergence are shown, where the use of nutrients as a novel way of osmopriming to alleviate abiotic stress effects and improve seedlings yield is discussed. Novel approaches to know the re-translocation from source leaves to developing seeds are considered, as an essential mechanism to understand the biofortification process of certain grains in order to cope with nutrient deficiencies, especially in arid and semiarid areas. Finally, the role of new genes involved in hormone-dependent processes, oxidative response and water uptake into the seeds during their development or germination, have been described as plant mechanisms to deal with abiotic stresses.

“…Cheyed (2008) and Al-Selawy (2011) concluded that regulation of seed germination through priming may lead to pre-adaptation. Priming of corn seed with KCl gave higher percentage of germination, germination rate index, coefficient velocity germination and index of seedling vigour compared with non-primed seed under salt stress (Badar uz Zaman et al, 2012). Lemrasky and Hosseini (2012) soaked seed of wheat for 45 h in 2 and 4 mg*L -1 of KCl, and the result was longer radicle and plumule.…”

Most cultivars of sorghum have low field emergence as common problem. Three experiments were carried out at Agriculture College, Baghdad University. First experiment was conducted in laboratory according to Complete Randomized Design (CRD) with four replicates. Second and third experiments were conducted at field according to Randomized Complete Block Design (RCBD) during the spring and the fall seasons of 2015, respectively, with four replicates for each one. Same two factors were studied at each experiment. First factor was seed priming by seed soaking for 10 hours in distilled water, solvents of GA3, KCl and thiamine (300, 40 and 30 mg*L -1 , respectively) and non-primed seed. Second factor was three cultivars of sorghum (Inqath, Kafier and Rabeh). The aim was to improve field emergence and grain yield of sorghum under wide range of environmental conditions by using seed priming. Data were analyzed at P˂0.05. The results showed significant effects of seed priming, cultivars of sorghum and their interaction on most traits under this study. A significant superiority of interaction was found between thiamine and Rabeh on length of plumule and dry weight of seedling at laboratory experiment. A significant superiority of interaction was found between thiamine and Rabeh on percentage of field emergence and total grain yield during spring season. A significant superiority of interaction was found between KCl and Inqath on percentage of field emergence and total grain yield during fall season. It can be concluded that technique of seed priming is effective to improve field emergence and grain yield of sorghum under wide range of environmental conditions.

“…It includes a number of different techniques of seed improvement, obtained through controlled hydration (Farooq et al, 2006). Some of the most commonly used seed priming treatments are hydropriming (Casenave & Toselli, 2007), osmopriming Badar-uz-Zaman et al, 2012), hormonal priming (Sneideris et al, 2015), and solid matrix priming (Pandita et al, 2010). Improvements in germination and emergence of primed seeds are reported to be the result of early DNA replication, increased RNA and protein synthesis, faster embryo growth and repair od deteriorated seed parts (Giri and Schillinger 2003).…”

The aim of this study was to investigate whether different priming treatments could affect emergence, speed of emergence and yield of freshly produced and aged maize seeds sown at different depths. Two lots of parental maize line A634 produced in the previous season were used as seed source, and twenty-year-old seed. After priming with distilled water and 0.5% KNO3 solution, the seed was sown at four depths. Results showed that freshly produced seeds did not benefit from priming treatments. Reaction of the aged seeds differed depending on the priming treatment. Results indicated that priming with KNO3 should be avoided in aged seeds of A634 because of its detrimental effect on the emergence and yield. Hydropriming induced higher percentage of emerged plants and faster emergence, but with no effect on yield. Reaction to priming treatments varied with sowing depth, which should not exceed 5.0 cm for parental line A634 according to this study.
