“…Among the vigor tests, MGT calculated in the cold test gave higher the coefficient (r=0.658**) and better in predicting field emergence percentage; however, this value was lower than that of the cold, AA and EC tests. These results agree with Matthews and Khajeh-Hosseini (2006) and Santorum et al .377* *, ** significant at %5 and %1 levels of probability, respectively (2013), indicating that MGT had potential as an indicator of seedling emergence in maize.…”

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.

“…This seems to indicate that both tests may be less suitable to predict seed behaviour in rather critical conditions. Matthews and Khajeh Hosseini (2006) reported significant correlations between mean germination time (MGT) at 13 °C in paper towels and final emergence or MET in soil in the growth chamber; similar correlations were found by Khajeh Hosseini et al (2009) with field emergence. In the latter work, considering that frequent counts are needed to determine the MGT, the Authors suggested that early counts of physiological germination (such as after 6 days at 13 °C) could be a more convenient and easy to standardise procedure to be used in the seed testing routine.…”

“…Recent papers (Matthews and Khajeh Hosseini, 2006;Ilbi et al, 2009;Khajeh Hosseini et al, 2009;Matthews et al, 2010) have suggested other procedures as potential routine vigour tests for maize such as mean germination time (MGT) or early counts of physiological germination measured at suboptimal cool germination (CG) or near to optimal temperatures in soil or in paper towels. The determination of the MGT, requiring several daily counts is, however, rather time-consuming and does not appear to be a practicable procedure in routine testing.…”

Cold test (CT) is widely used in maize for predicting field performance in early sowing, even though it is rather labour intensive and requires almost two weeks to complete. The objective of this work was to examine alternative procedures to CT suitable for routine testing. Standard germination (SG), CT and cool germination (CG) were carried out on 24 maize lots chosen with high (> 85%) SG. For the three tests, besides the final count of normal seedlings, early counts of germinated seeds were made. Lots were evaluated in two field trials (six replicates each) sowed at a very early and early date. For all the laboratory traits, the differences among lots were significant and attained higher values in the early counts compared to the final ones. Moreover, the correlations were high between early counts performed during the three tests but were in general lower between early and final counts. Early counts showed lower correlations with field performance than the final ones, except for the count at 144 h during CG that attained a correlation level with field emergence (r = 0.81) similar to the final counts of CG and CT. Nonetheless, the evaluation of seedling vigour during the final count of CT showed the highest predictive value of field performance. All the laboratory measures were in close agreement with field performance when the latter was evaluated under less unfavourable conditions.

“…There has been some research interest in the use of the RE test for the estimation of normal seedling counts during a germination, with seed lots with low levels of germination taking longer to reach the RE stage in maize, pepper and radish (Matthews and Khajeh-Hosseini, 2006;Demir et al, 2008a;Mavi et al, 2014). Recently, a test of seed lots of oilseed rape that had been in uncontrolled storage for several years, showed that the rate of RE, measured either as a mean germination time (MGT) or as a count of RE at 48 hours, was related significantly to a wide range of percentages of normal seedlings in the standard test (Khajeh-Hosseini et al, 2010).…”

An experiment was made to test the potential for radicle emergence (RE), and predict the germination percentage of normal seedlings both at constant (25 °C) relationship in both temperature regimes were reduced (for Thiram-threated seed lots ranging between R 2 =0.60-0.79 at 25 °C and 20/30 °C respectively, and for untreated lots ranging between R 2 =0.68-0.91 at 25 °C and 20/30 °C, respectively). Cumulative germination was slightly higher in the lots kept at fluctuating temperatures than in those kept at a constant temperature. The results showed that the RE test (i.e. 104 h count) can be used to make quick and repeatable predictions of the percentage of normal seedlings in aubergine lots. Moreover it was also significantly related to mean germination time (MGT) values at constant (R 2 = 0.769, p < 0.001) and alternating temperatures (R 2 = 0.861, p < 0.001).
