“…And they added that all morphological properties decreased with increasing the salinity in water. Also, Koyro et al (2008) showed that Chenopodium quinoa was able to complete its life cycle and produced seeds even at seawater salinity. However, the growth furthermore, the yield, number of seeds, weight and seed dry matter per plant were significantly reduced in the presence of salinity.…”

The experiment aimed to study the effect of the irrigation water quality on the growth of seedlings and its yield of quinoa plant through some traits i.e., plant height, number of leaves per plant, 1000 grains weight, dry weight per plant , stem diameter, inflorescence length and grain yield per plant. Four treatments were used as follow: T1 (low salinity water, EC 1.25 dS m -1 ), T2 (mix water between low salinity water and agricultural drainage water at ratio 1:1, EC 4 dS m -1 ), T3 (agricultural drainage water, EC 8 dS m -1 ) and T4 (high salinity water, EC 16 dS m -1 ). The treatments application was at the beginning of the plant buds so that the amount of irrigation water up to 75% from field capacity. The significant effects of treatments were found on all tested traits. Also, the results clarified that the rate of chlorophyll ranged between 44.18 (treatment T4) and 53.75 SPAD (treatment T3), water potential of the fourth leaf has ranged from -0.83 to -1.745 MPa for T1 and T3 treatments, respectively, number of leaves per plant was ranged between 26.5 and 28.5 when the plants were irrigated with T4 and T1 irrigation water treatments, respectively. The inflorescence lengths were varied between 8 cm at T4 treatment and 12 cm at T2 treatment. The plant height was ranged between 53.5 cm (T4) and 60.75 cm (T3). The low values of seed yield were recorded at T4 (17.05 g/plant) while the higher values were recorded with T2 treatment (34.08 g/plant). 1000-grain weight values were ranged between 2.97 g at T2 treatment, and 3.49 g at treatment T1.

“…Chenopodium quinoa is a highly nutritional seed crop from the Andean region with huge genetic variability, enabling its cultivation across a wide range of environmental conditions. Consequently, it has been chosen by the Food and Agriculture Organisation (FAO, ) as one of the future crops destined to provide food security (Koyro, Lieth, & Eisa, ). Amaranthus caudatus also produces edible cereal grains and leaves that are valuable as a nutritional food resource and has been characterized as a “new crop.” Both can be used in bread, noodles, pastry, salads, soups and have potential as alternative cereal crops (Shabala, ; Wang et al., ).…”

“…Some authors refer to C. quinoa as a facultative, or true, halophyte, because some varieties can be grown in salt at concentrations found in sea water and have optimal growth between 100 and 200 mM NaCl, and germination is affected only at NaCl concentrations higher than 400 mM (Hariadi, Marandon, Tian, Jacobsen, & Shabala, 2011;Jacobsen, 2003;Koyro et al, 2008;Turcios, Weichgrebe, & Papenbrock, 2016).

Seed priming has proved to be an effective method in imparting stress tolerance to plants using natural and/or synthetic compounds to treat the seeds before germination. The present work aimed to evaluate the effectiveness of priming treatments in seeds of Chenopodium quinoa and Amaranthus caudatus to improve germination under NaCl. Species-specific protocols for seed hydropriming and osmopriming were established by germinating seeds under different water potentials and creating seed imbibition curves. Primed seeds were then germinated under different concentrations of NaCl, and the effect of priming was analysed based on the parameters, such as final germination percentage (FGP), germination index (GI) and mean germination time (MGT). Seed hydropriming and osmopriming caused significant improvements in germination velocity and uniformity, reflected in high FGP, high GI and reduced MGT under salinity. C. quinoa had a higher tolerance to salinity than A. caudatus during seed germination. Improved germination in salinity resulted from osmopriming seeds with solutions of low water potential for A. caudatus, while for C. quinoa, this effect was achieved from hydropriming and osmopriming seeds with solutions of high water potential. Primed tolerance to moderate salinity was achieved for A. caudatus, and for both species, the salinity threshold for germination to occur was slightly broadened.

“…Drought stress is not only the consequence of a lack of water in the soil but may also be induced by other deleterious environmental conditions, such as salinity, which compromise the plant's ability to take up and to translocate water (Demirevska et al, 2009). Glycophytic plants, such as the majority of the common crops, are not salt tolerant and are damaged fairly easily by high salinity (Koyro et al, 2008). Salts on the outside of roots have an immediate effect on cell growth and associated metabolism, although toxic concentrations of salts take time to accumulate inside plants before these concentrations affect plant physiology (Munns and Tester, 2008;Geilfus et al, 2011).…”

Drought and salinity alter endogenous hormonal profiles at the seed germination phase

et al. 2015

The most critical phase in plant life is seed germination, which is influenced by environmental factors. Drought and salinity are key environmental factors that affect seed germination. Reduction or alterations of germination when seeds are exposed to these factors have been shown to be due to either the adverse effects of water limitation and/or specific ion toxicity on metabolism. Phytohormones are chemical messengers produced within the plant that control its growth and development in response to environmental cues; small fluctuations of phytohormone levels alter the cellular dynamics and, hence, play a central role in regulating plant growth responses to these environmental factors. To integrate current knowledge, the present review focuses on the involvement of endogenous phytohormones in plant adaptative responses to drought and salinity at one of the plant's developmental phases.
