چکیده مقاله :
Recently the use of plant products instead of chemical materials is one of the most important needs of the modern civilization in terms of human health. On the other hand, drought is one of the abiotic environmental stresses that reduce the performance of the products. The objective in this study was to assess the effect of nutri-priming with (control, Fe, Zn, Fe + Zn, nano- Fe, nano- Zn, and nano- Fe + nano- Zn) on quinoa seed germination indices and physiological characteristics in PEG 6000 (polyethylene glycol), drought condition (0, -3, -6, -9 and -12 atm). Results indicated that the effect of drought in nutri-priming were significant on germination percentage, germination rate, mean of germination time, germination uniformity, seedling length, seedling length index, seedling weight, seedling weight index and photosynthetic pigments. Drought stress decreased the percentage and rate of germination and seedling indexes, however, nutri-priming reduces the adverse effects of drought stress. Drough also reduced the amount of photosynthetic pigments, in spite of all that this decrease was very low in terms of nutri-priming with Fe, Zn, Fe + Zn, nano- Fe, nano- Zn, and nano- Fe + nano- Zn) in high drought level (-12 atm). drought stress increased, mean of germination time, germination uniformity, that nutri-priming especially with the control more increased. The finding of this study leads to the conclusion that nutri-priming with nutrients, especially nano- Fe + nano- Zn increased the germination indices of the plant to improve germination and seedlings growth of quinoa under drought stress.

Abstract
Recently the use of plant products instead of chemical is one of the most important needs of the modern civilization in terms of human safety. On the other, drought is one of the abiotic environmental stresses that reduce the performance of the plant products. The objective in this study was to assess the effect of nutri-priming with (control, Fe, Zn, Fe + Zn, nano- Fe, nano- Zn, and nano- Fe + nano- Zn) on quinoa seed germination indices and physiological characteristics in PEG 6000 (polyethylene glycol), drought condition (0, -3, -6, -9 and -12 atm). Results indicated that the effect of drought in nutri-priming were significant on germination percentage, germination rate, mean of germination time, germination uniformity, seedling length, seedling length index, seedling weight, seedling weight index and photosynthetic pigments. Drought stress decreased the percentage and rate of germination and seedling indexes, however, nutri-priming reduces the adverse effects of drought stress conditions. Drough stress also reduced the level of photosynthetic pigments, in spite of all that this decrease was very low in terms of nutri-priming with Fe, Zn, Fe + Zn, nano- Fe, nano- Zn, and nano- Fe + nano- Zn) in high drought level (-12 atm). drought stress increased, mean of germination time, germination uniformity, that nutri-priming especially with the control more increased. The finding of this study leads to the conclusion that nutri-priming with nutrients, especially nano- Fe + nano- Zn increased the germination characteristics of the plant to improve germination and seedlings growth of quinoa under stress conditions.

Quinoa (Chenopodium quinoa Willd) is a dicotyledonous plant, allotetraploid (2n=4x=36), from the Amaranthaceae family, C3 and optional halophyte (Yasui et al., 2016). Quinoa with about 95% self-fertilization originates from the Andes mountains on the west coast of Latin America (South). It is one of the plants under the spinach and sugar beet family, and despite its high nutritional value, it can be cultivated well in conditions of low or limited fertility and produces a suitable crop (Chitambo, 2019).
Quinoa seed contains 14-20% protein and is rich in essential amino acids such as lysine and methionine, which are found in very small amounts in most cereal plants (Ferreira et al., 2015). The very high nutritional value of quinoa seed has caused it to be compared to powdered milk in the World Food Organization (FAO), and it has been called multivitamin or herbal caviar (Vahidi et al., 2021). The absence of gluten in this grain has made it possible for celiac patients and those who are allergic to wheat gluten to consume it, because the rate of hydrolysis of quinoa proteins by bacterial lactic acid is higher than the hydrolysis of wheat protein (Caeiro et al., 2022).
Plants are constantly exposed to various biotic and abiotic stresses. Among these stresses, drought stress is one of the most important factors affecting the growth and fertility of plants, and as the most important abiotic stress, it plays an important role in reducing the yield of medicinal plants (Seleiman et al., 2021).
Seed priming is one of the methods used to develop drought tolerance in plants (Seleiman et al., 2021). Seed priming is a technique by which seeds are physiologically and biochemically ready for germination before being placed in their substrate and facing the ecological conditions of the environment. This can cause many biological and physiological manifestations in primed seeds and the resulting plant. So that these cases can be observed in the way of germination, early plant establishment, utilization of environmental inputs, early maturity, quantitative and qualitative increase of the crop (Tabassum et al., 2018).
In seed priming with micronutrient elements (Nutripriming), micronutrient elements are used as an osmotic material (Bhatia and Gupta, 2022). Primed seeds usually have better and more uniform germination (Waqas et al., 2019)due to less drinking time (Bourioug et al., 2020)and the production of metabolites that increase germination ((Pawar and Laware, 2018).
The positive effect of iron and zinc micronutrients on dry matter performance may be due to increasing auxin biosynthesis, increasing chlorophyll concentration, increasing the activity of phosphoenol pyruvate carboxylase (PEPC) and ribulose biphosphate carboxylase/oxygenase (Rubisco), reducing sodium ion accumulation in plant tissues and increasing the efficiency of nitrogen and phosphorus absorption in the presence of It is the elements of micronutrients. Micronutrients are vital for human health and plant growth(Mbarki et al., 2018).
Iran has a variety of climates, and the cultivation of quinoa in terms of production, especially in the southern regions, will create diversity in crops, sustainable production and food security (Fathi and Kardoni, 2020).
Due to lack of micronutrients in soils of Iran and on the other hand the importance of nutrients, especially Fe and Zn salient role in the vital processes and metabolism of plants under drought stress condition, the objective in this study was to evaluate nutrient seed priming with Fe, and Zn (nano and non-nano forms) on germination indices and biochemistry characteristic under drought stress in herb quinoa.

Procedure and seed germination test
The germination test was conducted in February 2017 in the Faculty of Agriculture of Shahid University of Tehran in the Laboratory of Seed Science and Technology. To perform this test, the seeds were first disinfected with ethanol (70%) for one minute and sodium hypochlorite solution (10%) for 3 minutes, and then they were washed 3 times with sterile distilled water (Hajihashemi and Ehsanpour, 2013).
In order to apply priming, the seeds were placed in the desired solutions (Fe, Zn, Fe + Zn, nano- Fe, nano- Zn, nano- Fe + nano- Zn) and after 6 hours, removed from the solution, on filter paper They were dried for 24 hours at room temperature (Farooq et al., 2011). The duration of priming is also based on the review of sources (Ashrafi and Razmjoo, 2010). After drying, 100 treated seeds and control (without prime) and 7 ml of PEG 6000 solutions with concentrations of 0, -3, -6, -9 and -12 atm was added. were wrapped with impermeable Parafilm to avoid the loss of moisture and evaporation, and the standard germination test performed in 4 repetitions at a temperature of 23 ± 1 °C, relative humidity of 75% and a light period of 16 h and 8 h of darkness for 14 days. At the end of the germination period, the characteristics of germination speed, germination percentage, average germination duration and seedling vigour indices were calculated based on the equations presented in Table 1.
Chlorophyll and Carotenoid Contents
0.5 g of fresh plant material was crushed in a mortar using liquid nitrogen. Then, 10 ml of 80% acetone was added to it in the dark and centrifuged for 10 minutes at 4°C with 6000 revolutions per minute (rpm). The upper part of the extract was transferred to a new test tube and covered with foil. Readings were then taken using a spectrophotometer at wavelengths of 663 nm, 645 nm, and 470 nm to measure chlorophyll a, chlorophyll b, and carotenoids, respectively (Arnon, 1967)
Chlorophyll a = (12.25 × OD₆₆₃.₂ nm – 2.79 × OD₆₄₆.₈ nm)
Chlorophyll b = (21.21 × OD₆₄₆.₈ nm – 5.1 × OD₆₆₃.₂ nm)
Total Chlorophyll = Chlorophyll a + Chlorophyll b
Carotenoid = [(1000 ×OD₄₇₀ nm – 1.8 ×Chlorophyll a – 85.02 × Chlorophyll b)/198]

As shown in Table 5, the maximum content of chlorophyll a, b chlorophyll, total and carotenoids contents were related to no drought stress (0 bar) and nutri-priming (nano-Zn + nano-Fe). Also interaction of the treatments showed the highest chlorophyll a, b, total chlorophyll and carotenoid contents were obtained in Nano-Zn + Nano-Fe nutrient treatment in without drought stress. Also, the lowest chlorophyll a, b chlorophyll, total chlorophyll, and also carotenoids content were obtained in nutrient control treatment under drought stress condition (Fig VII-X).
Discussion
The purpose of this research was to investigate the effect of nutri-priming on germination and physiological indicators of quinoa seedlings in drought conditions. According to the results, drought stress had adverse effects on germination indicators, which decreased the rate and percentage of germination, seedling length, and seedling vigor indices.

A decrease in water absorption by seeds and an increase in the level of ROS in water shortage conditions lead to poor and irregular germination (Zhang et al., 2021), which naturally leads to a disturbance in the transfer of nutrients to the seeds, resulting in less food storage and a decrease in uniformity and early ripening(Gough, 2020). According to reports, under stress conditions, changes in some enzymes and seed hormones can lead to a decrease in germination (Ali and Elozeiri, 2017).
Seed priming with nutrients (nutri-priming) caused beneficial effects such as increasing germination components and reducing the harmful effects of drought stress(Hussain et al., 2022). Among the nutritional treatments, the combination of nano-iron and nano-zinc had more positive effects on germination indices (Dhaliwal et al., 2021).

In the findings of different researchers, favorable effects of nutria- priming with nano-iron and nano-zinc nutritional compounds have been observed on various indicators of plant seed germination (Naghdi Badi et al., 2017). The improvement of seed germination indices in the effect of priming with nutrients can lead to a significant increase in seedling length and weight, as well as seed germination speed, which may be due to the effect of these elements in increasing cell division and meristem growth (Younis et al., 2019). Seed Priming with micronutrients allows to seeds that absorb water quickly and expand metabolism and germination, resulting in higher germination percentage, improved seedling growth, and increased tolerance to drought stress (Waqas et al., 2019).
Conclusions
The results of this study showed that priming with nutrients under drought stress improves the germination characteristics of quinoa seeds. The process of adaptation to water stress, started by nutritional treatment, can be attributed to pre- priming with nutrients before applying water stress. Among the nutritional treatments, the combination treatment of nano-iron and nano-zinc showed better results at all levels of drought stress. Among the drought stress levels, a significant difference was seen in most of the traits, which showed better results in the treatment of drought stress. In general, it can be stated that due to the better and more uniform germination of primed seeds with micronutrient elements, it will improve the initial establishment, utilization of environmental inputs, early arrival, increase in quantity and quality of the product.
