“…The results of IV_Vigor.S showed the ability of the technique in distinguishing the level of vigor in the two cultivars under study according to the percentages of green soybean seeds, corroborating the studies of Castan et al (2018), Medeiros et al (2019), andRodrigues et al (2020), which showed the efficiency of Vigor-S in evaluating the vigor of maize, common bean, and soybean seeds, respectively.…”

The multispectral image analysis technique to detect chlorophyll fluorescence (CF) in soybean seeds was studied to assess the relationship between CF signals and seed physiological potential. Eight treatments, corresponding to 0%, 2%, 4%, 6%, 8%, 10%, 12%, and 14% green seeds, were used on two cultivars, BMX Desafio RR 8473 RSF and 96R10 IPRO, which passed through different seed quality tests. Initially, the CF of the seeds was determined using 660 nm and 730 nm spectra, and then the germination, electrical conductivity, accelerated aging with saturated NaCl solution, tetrazolium, and computerized seedling image analysis (Vigor-S) tests were performed on the same seeds. A completely randomized design was used, as well as replications of each treatment. Analysis of variance (ANOVA) was performed on the data from germination, vigor, and CF tests using the R® software, and the means were grouped by the Scott-Knott test (p ≤ 0.05). Pearson’s linear correlation coefficients (r) were calculated for all combinations among the evaluations with significance of the r values determined by the t-test (p ≤ 0.05), and multivariate analysis of the principal components was performed. Proportional increases in green seeds contribute to an increase in chlorophyll fluorescence signals and have a negative correlation with seed physiological quality; levels above 4% green seeds in the samples result in marked losses in physiological potential. Therefore, the chlorophyll fluorescence detected through multispectral images is inversely related to the physiological potential of soybean seeds.

“…Furthermore, the indexes generated by Vigor-S have been recommended for the accuracy of the results for the vigor of soybean seed lots, as reported by Rodrigues et al (2020). This analysis can be made in a quick and streamlined manner; as shown in the present study, the software provides robust results that have moderate implications for the storage capacity of soybean seeds.…”

“…At the end of this period, the seedlings from each sample were placed on a sheet of blue ethyl vinyl acetate and scanned using an inverted scanner in a metal box. Images were generated at 300 DPI and analyzed using the software Vigor-S®, following the parameters described by Rodrigues et al (2020) to calculate vigor index, growth index, development uniformity index and seedling length.…”

Is it possible to estimate longevity through the analyses used to measure the initial physiological potential in soybean seeds?

The analysis of longevity can support decisions about the length of seed lot storage until commercialization, since this characteristic implies the maintenance of viability over time. Seed longevity is analyzed by the p50 test, which expresses the time to lose 50% of the initial viability. Seeds with high vigor and germination have greater physiological potential and, thus, a greater capacity to maintain quality throughout the storage period. However, there has been little research on the correlations between the analysis of p50 (longevity) and the tests used to measure physiological potential (germination and vigor) of lots, which can be used as a tool to make inferences about longevity using the most traditional tests. Thus, the objective of this study was to investigate which tests used to measure the potential of lots can estimate p50. To this end, germination and vigor were evaluated using traditional tests while longevity was assessed in eight soybean seed lots. Correlations and linear regression were tested for the traditional variables versus p50. It was found that the use of accelerated aging, electrical conductivity, and time to 50% radicle protrusion has high potential to estimate longevity as measured by p50.

“…Os rolos foram mantidos em germinador a 25 ± 1 °C durante três dias. Após este período foram determinados os índices de vigor e de uniformidade de desenvolvimento, comprimento de plântula, comprimento de hipocótilo e comprimento de raiz, utilizando imagens processadas no software Vigor-S (RODRIGUES et al, 2020).…”
