“…In our study, the results of EC test significantly correlated with field emergence of soybean. Similar findings were observed in legumes by Colete et al (2004) and Vieira et al (2004) in soybean, Panobianco et al (2007) and Atak et al (2008) in pea, Makkawi et al (1999) in lentil, Silva et al (2013) in common bean. They noted that the EC was clearly related to germination and emergence percentage, and lower emergence was observed in seeds with higher EC.…”

“…Colete et al (2004) and Vieira et al (2004) reported that electrical conductivity (EC) may be efficient to determine seed vigor in soybean while Salinas et al (2010) the minimum 19 hours must require for the stable EC results in soybean. Marcos-Filho et al (2001) found the accelerated ageing and controlled deterioration tests could be used to select vigorous seed lots in soybean.…”

“…On the other hand, Gamiely et al (1990) have evaluated seed element concentrations for the viability and vigor of the seed in onion and Kaymak et al (2012) found a significant correlation between field emergence and some element concentrations in bean seed. Although there are several kinds of researches on the vigor tests, different tests have been advised for estimating seedling emergence in soybean by Kulik and Yaklich (1982), Colete et al (2004), Torres et al (2004), Vieira et al (2010) and Santorum et al (2013) in consequence of using limited seed lots or several lots of a variety. Consequently, the present study was carried out to assess the efficiency of various seed vigor tests and seed mineral element concentrations to rank seed lots, and to identify the most suitable test which could forecast the field performance using fifty seed lots of soybean.…”

The relationship between seed vigor test and seedling emergence is crucial to predict easily the seed performance under field conditions and the seed producers continuously explore the best vigor test to enhance stand establishment. This study was conducted to determine the suitable seed vigor test and mineral element in the seed to predict accurately the field performance of soybean. Fifty seed lots of 22 commercial soybean cultivars were assessed for seedling emergence under field conditions and germination, emergence, cool and cold tests, electrical conductivity (EC) and pH for 4, 8 and 24 h, accelerated ageing (AA) at 41, 43 and 45°C for 48, 72, 96, 120 and 144 h in the laboratory. Initial seed weight, oil, protein, P, K, Ca, Fe, Mn and Zn concentration in seed lots were also investigated. Their results were correlated with field emergence percentage of seed lots to detect the most suitable indicator for vigorous seed lot. The germination percentage varied from 56% to 100%, while the field emergence percentage ranged between 0% and 84%. No significant correlation was noticed between field emergence and seed weight, oil and protein contents. AA test at 41°C for 72 h gave the highest significantly positive correlation with r=0.831**, but the highest significant and negative correlation coefficient (r=-0.801**) with field emergence percentage were observed in EC test for 24 h. Only Mn concentration of six elements investigated was significantly correlated with field emergence (r=-0.376*). It was concluded that the AA condition of 72 h at 41°C are recommended as an ideal seed vigor test to estimate closely field emergence performance of soybean seeds.

“…EC test results have demonstrated a desirable efficiency to indicate seed performance to establish the stand under a wide range of field conditions, as reported for soybean seeds (Colete et al, 2004;, as well as an important vigor test for this specie (Vieira et al, 1999a(Vieira et al, , 1999b. Gotardo et al (2001) also showed that this test can be used to assess corn seed vigor.…”

-The objective of this work was to evaluate the effects of temperature (10, 20, 30, 20/10 and 30/10ºC) and period of storage on electrical conductivity (EC) in four seed lots of corn (Zea mays L.), as well as the mineral composition of the soaking solution. EC test determines indirectly the integrity of seed membrane systems, and is used for the assessment of seed vigor, because this test detects the seed deterioration process since its early phase. The research comprised determinations of water content, germination, accelerated aging (AA), cold (CT) and EC vigor tests, and determinations of Ca 2+ , Mg 2+ and K + release to the solution, after seed soaking of four corn seed lots. The evaluations were performed each four months during a period of 16 months. For statistical analysis, a completely randomized split plot design was used with eight replications. Except for seed lots stored at 10ºC, all vigor evaluations revealed a decline in vigor, but AA and CT showed more sensitiveness to declines of seed physiological quality than EC. Potassium was the main leached ion regardless of the storage temperature.

“…A similar result was reported in conditioned lettuce seeds. According to the authors, the electrical conductivity test can be useful in the evaluation of conditioned seeds, but it only indicated an increase in seed vigor of the conditioned seeds compared with those of the control treatment (Colete et al, 2004;Rodrigues et al, 2012).…”

Castor bean (Ricinus communis L.) cultivation requires production techniques appropriate for its growth conditions. Thus, the characterization of the deleterious effects of salinity on seed germination and on seedling establishment and the evaluation of the use of priming techniques on seeds could reduce replanting costs and improve emergence uniformity, preparing plant responses to salt stress. The goals of this current research were to characterize the deleterious effects of salinity on seed germination and on seedling establishment and to evaluate the use of the seed priming techniques as a tool to minimize these deleterious effect. In this research, castor bean seeds, cv. BRS-Energia was used to characterize effects of salt stress on germination and seedling establishment. Then, some chemicals such as PEG-6000 and H 2 O 2 were evaluated to find the beneficial priming techniques for castor bean seeds against salt stress. Our results indicate that water imbibition by the seed under salinity conditions decelerated the time of exposure to salinity. Salinity also affected the germination of castor bean seeds under an Ψs of -0.4 MPa and seedling growth was already affected under an Ψs of -0.16 MPa. Priming with CaCl 2 , NaNO 2 , NaNO 3 and PEG-6000 showed promising results under an Ψs of 0.0 MPa, but priming with NaNO 3 and PEG-6000 were ones that contributed most to better germination and establishment of seedlings under saline conditions. However, NaNO 3 is the most recommended priming agent for castor bean because accelerated seed germination, reducing the time to emergence and planting risks.
