“…In the present study primed seed with suitable concentration of salts and hydropriming (C2) showed better performance in respect to non-primed (C0) and other treatments. A number of studies showed similar enhancement strategy in germination and seedling establishment of crops in case of all the used mineral salts (Barbosa et al, 2016;Salles et al, 2019;Kumar et al, 2020;Choudhary et al, 2021).…”

Ca(NO 3 ) 2 seed priming of crops potentiates the germination process, resulting in increase germination and radicle emergence rates (Salles et al, 2019). It also improves speed of germination, length of seedling, fresh and dry biomass of seedling and allows a greater expression of seed vigor in various crops (Barbosa et al, 2016;Gouveia et al, 2017;Maneesha, 2019).…”

Seed is the most valuable input in agriculture, and high-quality seeds are required for healthy crop production. Various seed quality enhancement technologies are continuously used for better establishment of crop in field. Seed priming is one of the best, cheapest, reliable and cost-effective strategies to boost seed germination and seedling establishment. This experiment was conducted to determine the effect of seed priming with various concentration of Mg(NO3 )2 , and Ca(NO3 )2 salts in two tomato genotypes (VRT 06 and Punjab Chhuhara) on germination and seedling growth. The concentration level C0 to C7 (2.5 mM to 20 mM) were used for priming purpose and germination parameters were recorded. From the study of germination %, mean germination time (MGT)(days), Germination index (GI), Coefficient of velocity of germination (CVG) and Germination rate index (GRI) (%/day), seedling length (cm), seedling fresh weight (FW) (mg), seedling dry weight (DW) (mg) and seedling vigor index (SVI), it was revealed that 7.5mM of Mg(NO3 )2 , and Ca(NO3 )2 , were the most effective treatments, which were able to improve performance of seedling establishment of tomato seeds.

“…The initial results demonstrate similarities in the effect of both calcium nitrate and potassium nitrate on seed conditioning for seedlings at 33 DAS. According to Salles et al (2019), the priming of eggplant seeds with calcium nitrate resulted in the highest germination rate of seeds and seedlings with the highest radicle emission rate. Calcium nitrate and potassium nitrate are salts that can release nitric oxide (NO), which are required in several physiological processes related to plant growth and development and provide resistance to abiotic stresses and resistance to pathogens (Sanz et al, 2015).…”

“…The incorporation of chemical agents in the method of physiological conditioning of seeds (priming) is a way to guarantee vigorous seedlings (Kerbauy, 2013;Caixeta et al, 2014;Batista et al, 2015;Marcos Filho, 2015;. Nitric oxide, which is obtained using salts such as calcium nitrate and potassium nitrate, can be used to favor plant development and growth (Sanz et al, 2015;Salles et al, 2019). The effects of nitrate are related to several pathways in the initial germination processes and even in overcoming seed dormancy (Brasil, 2009;Kerbauy, 2013;Cardoso et al, 2015;Sanz et al, 2015).…”

This study aimed to evaluate the effect of nitrate salts and a growth regulator on seed conditioning. Subsequently, the responses of the influence of the leaf application of paclobutrazol (PBZ) and nitrogen on the quality of seedlings of Capsicum frutescens L. were evaluated. Two experiments were carried out. The first experiment was conducted in a completely randomized design to evaluate priming, as follows: T1 – control, T2 – control (water), T3 – 0.2% calcium nitrate, T4 – 0.2% potassium nitrate, T5 – 0.1% calcium nitrate + 0.1% potassium nitrate, T6 – PBZ, and T7 – PBZ + 0.1% calcium nitrate + 0.1% potassium nitrate. The second experiment was carried out in a completely randomized design in a 2×5 factorial scheme consisting of priming (absence and presence of calcium nitrate) and leaf application of growth regulator, as follows: control (water), PBZ, PBZ + 1% nitrogen (calcium nitrate), PBZ + 1% nitrogen (urea), and PBZ + nitrogen (0.5% calcium nitrate + 0.5% urea). Physiological conditioning with a solution of 0.1% calcium nitrate increased the germination and seedling emergence rate and resulted in seedlings with a higher shoot length at 33 days after sowing (DAS), but seedlings at 50 DAS showed no differences in growth with its use. Leaf application of 0.1% paclobutrazol provided pepper (C. frutescens L.) seedlings with better distribution in growth according to the Dickson quality index.

“…However, the difference between the 3 and 4 mM levels of Ca(NO 3 ) 2 in the control was not significant. The results of the various levels of calcium nitrate on the seed germination showed different responses (Salles et al 2019). Shabala et al (2006) suggested an extra mechanism of the calcium function in salinity-stressed plants:…”

Salinity is one of the critical environmental factors that decreases the water availability and induces nutritional imbalance in crops. In order to study the effect of calcium nitrate [(Ca(NO 3 ) 2 ] in the nutrient solution under salinity conditions, an experiment was designed with different salinity (0, 50, and 100 mM) and Ca(NO 3 ) 2 (2, 3, and 4 mM) levels on Cucurbita pepo (zucchini). Based on the results, an increase in the salinity from 0 to 100 mM caused a decrease in the leaf potassium and calcium concentration, whereas the iron, magnesium and zinc concentrations increased. The most effective Ca(NO 3 ) 2 level in increasing the nutritional quality and yield of zucchini was 3 and 4 mM. Salinity at 50 and 100 mM significantly increased the leaf sodium concentration and leaf area as well as the leaf number per plant, while the application of both Ca(NO 3 ) 2 levels modulated the harmful effects of salinity. The amount of malondialdehyde (MDA), proline and hydrogen peroxide (H 2 O 2 ) as well as the catalase (CAT) activity increased under the severe salinity conditions, whereas the application of 4 mM Ca(NO 3 ) 2 had the potential of removing the negative effects of severe salinity. The catalase activity increased along with the increase in the Ca(NO 3 ) 2 concentration, which was independent from the salinity level. However, the amount of proline, MDA and H 2 O 2 decreased in plants fed with 3 and 4 mM Ca(NO 3 ) 2 compared to the control in the presence of salinity. These findings suggest that both the 3 and 4 mM concentrations of Ca(NO 3 ) 2 under 50 mM salinity could be used to improve the zucchini performance by maintaining the ion homeostasis and inducing the antioxidant defence system.
