“…Priming treatment is a successful practice for improving seed germination criteria performance and/or counteracted the harmful effect of drought stress. These results corroborate with the finding of Jalilian et al [52]; Rouhi et al [53] for hydropriming; and Ansari et al [4]; Rouhi et al [6]; Espanany et al [54] for potassium nitrate priming; and Afef et al [32], Hameed et al [35]; Ghajari et al [55] for silicon priming as well as Rouhi et al [53]; Aghbolaghi and Sedghi [56] for polyethyleneglycol, and Hamada and Khulaef [57]; Sayed and Gadalla [58] for thiamin they found that germination parameter were significantly increased by seed priming treatment under normal or drought stress conditions. Moreover, primed seedlings are known to emerge additional quickly and grow additional vigorously than those from nonprimed seeds [59].…”

Seed priming is currently a wide used commercial process that accelerates the germination rate and improves seedling uniformity in several crops. A laboratory study was conducted to evaluate the effect of grain priming treatments on barley grain germination and seedling growth under drought stress imposed by PEG-6000. The experiment was performed employing a factorial completely randomized block design with four levels of drought stress (0,10,20 and 30% PEG6000) and 14 priming treatments (dry, hydropriming, 5, 10, 15% PEG-6000; 500, 1000, 1500 mg/l KNO 3 ; 25, 50, 75 mg/l thiamin; 50, 100, 150 mg/l sodium metasilicate) with five replications for each treatment. Germination percentage, germination index, energy of germination, mean germination time, seedling vigor, seedling length, 10 seedling fresh and dry weights were measured below the experimental conditions. Variance analysis results (ANOVA) showed extremely significant (p<0.05) variations between treatments in all traits. It had been discovered that increasing PEG concentrations up to 30% significantly decrease germination criteria and seedling growth traits and that priming treatments in most cases significantly increased all germination and seedling parameter. The most effective in this regard was 1000 mg/l potassium nitrate as compared with untreated control treatment. Priming treatments in most cases mitigates PEG effects as a major increase, particularly with 1000 mg/l potassium nitrate. It is concluded that potassium nitrate at 1000 mg/l is helpful to enhance drought tolerance of barley grain germination and seedling growth.

“…Similarly, nitrogen is an essential element for healthy and vigorous plant growth at early growth stages . The positive role of KNO 3 seed priming against various abiotic stresses such as drought, salinity, high temperature and cadmium toxicity is well reported; however, reports regarding the possible effects of KNO 3 seed priming on growth and Pb accumulation in plant species are scant. The present study was carried out with the hypothesis that an exogenous KNO 3 supply significantly ameliorates Pb induced toxicity in Zea mays .…”

“…This efect can be atributed to the activation of seed repair mechanisms after exposure to adverse conditions, accumulation of germination-promoting substances, nutrient accumulation and osmotic adjustment (AO) [78,79]. This technique has been shown to be strongly associated with increased antioxidant defence in New Perspectives in Forage Cropsgerminated seeds, which allows beter tolerance to oxidative stress, reduction of lipid peroxidation and increase in membrane stability under water deicit conditions [15,80].…”

Alfalfa (Medicago sativa L.) is one of the most cultivated forage legumes in Morocco thanks to its great adaptation to the climatic conditions of this country, its high protein content and its ability to ix atmospheric nitrogen in symbiosis with rhizobia. Environmental stresses such as drought and salinity constitute a major factor limiting the symbiotic nitrogen ixation and legume productivity. In the last decades, this process has interested scholars in understanding the implication of these strains in legume stress tolerance in order to make these symbioses more eicient under diicult conditions. Seed osmopriming is a great technique in the amelioration of seed germination and seedlings growth in responses to several abiotic stress conditions. In this chapter, the efects of water deicit on the Moroccan alfalfa populations and their symbiotic association with rhizobia were discussed. Besides, osmopriming could make these symbioses more eicient especially under stress conditions.
