“…More other researchers also reported the deleterious effects of salinity (NaCl) on seed germinability and seedling growth of many crops. The reasons of reduced germination percentage can be attributed to primary water uptake reduction and the adverse effect of osmotic potential and ion toxicity on physiological processes of seed germination (Tabatabaei, 2006;Javadi et al, 2015). In between the different levels of salinity stress, a small increase in compared to the control (without salinity stress), caused increase seed germination percentage.…”

“…In between treatments, priming with Se alone and in combination with Fe and with Fe and B showed maximum proline in high salinity stress. Javadi et al (2015) concluded that proline acts as a signaling/regulatory molecule and in the case of salt stress will be able to enhance the resistance of the plant to salinity. Zhang et al (2006) reported that there is a positive relationship between proline accumulation and the antioxidant level in the plant that the free radicals (ROS) caused by stress increases and leads to accumulation of free proline in the plant.…”

“…In this regard, Jamil et al (2005); Patade et al (2011); Rouhi et al (2011); Ansari and SharifZadeh (2012) stated that increasing salinity concentration causes reduced the germination percentage and seed germination time. Salinity to change the balance of plant hormones such as reducing hormones auxin, cytokinin, gibberellic acid and salicylic acid and increase abscisic acid and jasmonate in plant tissue, causes damage to seed germination via important factors such as reducing water availability, changes in domestic reserves seed mobility and impact on protein structures organized (Machado Neto et al, 2004;Ibrahim Ehab, 2016).…”

“…Different priming methods include hydro-priming, osmo-priming, halo-priming, thermo-priming and hormone-priming that different reports on different plants this priming are presented by researchers (Iqbal et al, 2012;Mirshekari, 2015). One of the newest priming methods, using micro or macro nutrients for the seed treatment before sowing is called nutripriming Mirshekari, 2015).…”

-Poor germination and low seedling growth of stevia (Stevia rebuadiana Bertoni) are common problems in the cultivation of the plant. On the other hand, salinity is one of the abiotic environmental stresses that reduce the performance of the product. The objective in this study was to assess the effect of nutri-priming with selenium (Se), iron (Fe) and boron (B) on stevia seed germination indices and physiological characteristics in sodium chloride (NaCl) salinity condition (0, 30, 60 and 90 mM). Results indicated that the effect of salinity in nutri-priming were significant on germination percentage, germination rate, germination uniformity, germination value, seedling length, seedling vigor index, total chlorophyll, free proline content and enzymatic activity of catalase (CAT) and superoxide dismutase (SOD). Salinity stress decreased the percentage and rate of germination and seed vigor, however, nutri-priming reduces the adverse effects of salinity stress. Salinity also reduced the amount of chlorophyll content, in spite of all that this decrease was very low in terms of nutri-priming with Se, Se+Fe and Se+Fe+B in high salinity level (90 mM). Salinity stress increased proline content and antioxidant enzyme activities of CAT and SOD, that nutri-priming especially with the Se more increased. The finding of this study leads to the conclusion that nutri-priming with nutrients, especially Se and Fe increased the antioxidant capacity of the plant to improve germination and seedling growth of stevia under salinity stress.Index terms: antioxidant activity, chlorophyll, germination rate, germination uniformity, seed vigor.Efeito do amortecimento de nutrientes nos índices de germinação e nas características fisiológicas da plântula de stevia sob o estresse de salinidade RESUMO -A má germinação e o baixo crescimento das mudas de stevia (Stevia rebuadiana Bertoni) são problemas comuns no cultivo da planta. Por outro lado, a salinidade é um dos estresses ambientais abióticos que reduzem o desempenho do produto. O objetivo deste estudo foi avaliar o efeito do selênio (Se), ferro (Fe) e boro (B) nos índices de germinação de sementes de stevia e características fisiológicas na condição de salinidade com cloreto de sódio (NaCl) (0, 30, 60 e 90 mM). Os resultados indicaram que o efeito da salinidade na nutrição foi significativo na porcentagem de germinação, na taxa de germinação, na uniformidade da germinação, no valor da germinação, no comprimento da plântula, no índice de vigor da plântula, clorofila total, teor de prolina livre e atividade enzimática da catalase (CAT) e superóxido dismutase (SOD). O estresse por salinidade diminuiu a porcentagem e a taxa de germinação e vigor de sementes, no entanto, o amortecimento de nutrientes reduz os efeitos adversos do estresse por salinidade. A salinidade também reduziu a quantidade de teor de clorofila, apesar de tudo isso, esta diminuição foi muito baixa em termos de nutrição com Se, Se + Fe e Se + Fe + B em alto nível de salinidade (90 mM). O estresse de salinidade aument...

Nano-fertilizers with higher efficacy compared to conventional fertilizers can provide advantage for plant cultivation in both productive and problematic soils. Therefore, this study aimed to determine the effect of nano-calcium (nano-Ca) on lettuce plants grown in saline-boron toxic soil. Nano-calcium fertilizer was prepared from eggshells. Functional and structural properties of nano-Ca was determined by scanning electron microscopy (SEM), x-ray diffraction (XRD) and fourier transform infrared spectroscopy (FTIR) before plant experiment. The treatments was; control, 40 mM NaCl and 20 mg kg−1 B (NaCl + B), and 40 mM NaCl and 20 mg kg−1 B with 4 mM Nano-Ca (NaCl + B + nano-Ca). The nano-Ca significantly increased the dry weight and calcium (Ca) concentration of lettuce plants under saline-B toxic conditions. Although there was a decrease in the concentrations of sodium (Na), chloride (Cl), and boron (B) with nano-Ca treatment, it was not statistically significant. Salinity and boron toxicity lead to increased lipid peroxidation. In the present study, the production of malondialdehyde (MDA) as a marker for lipid peroxidation, along with a significant decrease in hydrogen peroxide (H2O2) concentration, was observed with the application of nano-Ca. There was no significant alteration in superoxide dismutase activity (SOD) observed in lettuce grown under saline and boron toxic conditions. However, catalase activity (CAT) increased with nano-Ca application, while the activity of ascorbate peroxidase (APX) decreased. The study results suggest that nano-Ca serves a protective function for lettuce plants cultivated under saline and boron toxic conditions.
