“…Seed emergence of many species is stimulated by plant growth regulators and inhibited by salt stress (Sparks, 2005). These results are in agreement with Foti et al (2008), who observed faster development, earlier flowering and maturity, and higher yields of maize under different seed priming types. Sedghi et al (2008) demonstrated that priming with gibberelline increases the rate and percentage of seedling emergence in comparison with auxin in medicinal pumpkin (Cucurbita pepo).…”

-The objective of this work was to determine the effects of seed priming and sulfur application on cell membrane characteristics, seedling emergence, chlorophyll content and grain yield of soybean (Glycine max) in saline soil. A complete-block design in 4x3 factorial arrangement with three replicates was used to test four types of seed priming (water, auxin, gibberellin and non-priming) and three levels of sulfate availability (0, 70 and 140 kg ha -1 K 2 SO 4 ). The soil had a silty loam texture with an electrical conductivity of 3.61 ds m -1, a pH of 8.2 and a saturation percentage of about 46%. Seed priming had significant effects on mean emergence rate (MER), emergence percentage, relative water content (RWC) of leaves, relative chlorophyll content, time of maturity, shoot length and grain yield. The highest values for these variables were observed in the priming treatments, except for the time of maturity. Sulfur application had significant effects on MER, shoot length, RWC, membrane injury index and grain yield. Priming treatments provide greater emergence rates and grain yields and interact sinergicaly with sulfur rates.

“…Thus, a fast and uniform initial development of plants is highly desired for maize crop, especially under stressful conditions. Foti et al (2008) found that small amounts of Cu applied via seed priming on maize increased the number of germinated seeds compared to the control. On the contrary, Luchese et al (2004) reported a toxic effect of Cu applied via maize seeds, obtaining lower seedling emergence percentages.…”

Seed treatment is a low-cost and efficacious method to deliver a diversity of compounds to field crops. This study evaluated the uptake of seed-applied Cu by maize and the effect on seed vigor. The treatments were composed of a control (untreated seeds) and five dosages of Cu: 0.11, 0.22, 0.44, 0.88 and 1.76 mg Cu seed -1 , applied as cuprous oxide and copper oxychloride formulations. Seedling emergence and the speed of seedling emergence were determined in three periods: 1, 60 and 120 days after Cu application. Evaluations of root and shoot dry mass, Cu tissue concentration and efficiencies of Cu uptake and incorporation were conducted with two-leaf stage maize plants. Seed-applied Cu reduces the speed of maize seedling emergence, while the final emergence percentage is not affected. Shoot dry mass tends to increase with the application of Cu, while there is no interference on root dry mass within the dosages tested. Cu tissue concentration of both roots and shoots increases as higher dosages of Cu are applied to seeds, with higher accumulation in roots. Cuprous oxide promotes higher uptake of Cu by maize roots compared to copper oxychloride.

“…The effect of NaCl priming is greater when salt treatment was applied at germination than when applied at seedling stage (Sedghi et al, 2010). The effect of seed priming on growth and yield have rarely been studied in many plants including maize (Foti et al, 2008).The present study investigate the effect of seed priming with NaCl on the growth and yield of two maize cultivars when subsequently exposed to salinity.…”

Salinity is one of the biggest limitants for agriculture in semi-arid areas of the world. An experiment was conducted to study the effect of seed priming with 6 dS m–1 NaCl on growth and yield responses of two maize cultivars (Azam and Sarhad yellow) exposed to three levels of salinity (0, 6, 8 dS m–1). Statistical analysis of the data revealed that cultivars, seed priming with saline water (6 dS m–1) and subsequent exposure to salinity stress had a significant (p < 0.05) effect on germination, days to emergence, plant height, shoot fresh weight, shoot dry weight, leaf area, shoot Na+, K+, proline, abscisic acid contents and yield variables. The results suggested that increasing salinity level had a negative effect on the growth and development of both cultivars under study. Analysis of the data also revealed that maize cv Azam performed better than cv. Sarhad yellow when exposed to different levels of salinity. Priming of cv Azam with NaCl resulted in earlier emergence (2 days) and germination rate (31.92%), plant height (12%), shoot proline (950.33 μg g–1 fresh weight) and ABA levels (0.983 and 1.203 μg g–1 fresh weight) and yield (36% than the non-primed treatment). These results suggest that priming of maize seeds with NaCl before sowing induces physiological and biochemical changes, which resulted in better performance when subsequently exposed to different levels of salinity.
