“…Kaya et al (2006) showed that hydropriming increased germination and seedling growth under salt and drought stress during germination in sunflower. Osmopriming is standard priming method that involves the use of adverse osmotic solution like mannitol, polyethylene glycol or salts such as chlorides, sulphates, nitrates to control water potential (Chen et al, 2010;Papastylianou and Karamanos, 2012). The usefulness of osmopriming with KNO 3 was shown in different plant species (Kaya et al, 2006;Eskandari and Kazemi, 2011).…”

Low temperature has a negative effect on germination parameters and early seedling growth. Seed priming is a beneficial pre-sowing treatment that partially hydrates the seeds to the point of germination process initiation, followed by drying which prevents radicle protrusion. The aim of this study was to evaluate the effect of different seed priming treatments on some maize seed vigor and early seedlings growth parameters at different temperature conditions. Seeds were primed in water (hydropriming) and KNO 3 solution (0,1% and 0,5%) at 25°C for 17 h. Germination was tested at 25°C, 15/25°C and 15°C. Seed priming treatments had more improving effects on studied seed and seedlings traits under suboptimal (15°C and 15/25°C) than at optimal temperature conditions. Seed priming treatment with 0,5% KNO 3 had the most beneficial effects and increased the most of studied parameters under suboptimal conditions. Seed priming with KNO 3 could be used to achieve higher seed vigor and seedling growth at suboptimal temperature conditions in maize.

“…Priming starts some of the metabolic process to occur in germination without a radicle protrusion. Various seed priming techniques have been developed in different medias: hydropriming (water), osmopriming (low water potential solutions such as polyethylene glycol -PEG), halo-priming (salt solutions) (Hamidi, Pirasteh-Anosheh, & Izadi, 2013;Chen, R. Arora, & U. Arora, 2010). Seed priming with nitrate solutions resulted in better seed quality and stand establishment in maize field grown (Hanegave, Hunje, Nadaf, Biradarpatil, & Uppar, 2011).…”

Priming has been used to improve the performance of germination at the field, and potassium nitrate (KNO 3 ) is a promising compound for this purpose. The nitrate (NO 3 ) could be absorbed, being used in the metabolism of the embryo, through the enzyme nitrate reductase (NR). Besides, the priming could also activate the response of the antioxidant system, becoming the primed seeds more prepared for possible stresses. Thus, the aim of this study was to evaluate the metabolic effect of nitrate in tomato seed germination by the quantification of NR activity, and also evaluate the activity of some antioxidant enzymes as superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX). Tomato seeds were primed using solutions of polyethylene glycol (PEG 6000) -1,1MPa, 50 mM KNO 3 and PEG+KNO 3 . The variables analyzed were germination (germinability, mean germination time, mean germination rate, coefficient of variation of the germination time, uncertainty and synchrony) nitrogen, total proteins and enzymes. The germination data were analyzed using an ANOVA, comparing the averages by Scott-Knott test (P < 0.05). To analyze the nitrogen, protein and enzymatic activities, we used a Kruskal-Wallis test (P < 0.05). The results show an increase in the NR activity, as well as in the antioxidant enzymes. The germination time (t) and germination rate (v) primed in KNO 3 had a better performance compared to the other treatments. In conclusion, the observed benefits in tomato seeds primed with KNO 3 were related to the activity of the enzyme nitrate reductase in the production of nitrite/nitric oxide, which acted promoting a faster germination.

“…Similar results have been reported in Refs. [92] after 48 h of osmopriming for spinach seeds and after 12 h of osmopriming in [33] for alfalfa under saline stress. Under similar conditions, the Adis-Tata population showed the greatest stability of the membrane compared to the other genotypes studied.…”

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.
