“…The correlation circle ( Figure 3B) confirms the high correlation found between the variables obtained from computerized analysis and the traditional vigor tests, with emphasis on the close relationship between the cold test and germination at low temperature test with the corrected vigor index at four days after setting up the test. High correlation between the cold test and the CVI generated by the SAPL® software was also found for maize (Medeiros, Pereira, Silva, Capobiango, & Flores, 2019a).…”

Computerized seedling analysis is a promising tool for assessing seed vigor, providing reliable and less subjective results. The aim of this study was to define a method for evaluating the vigor of chickpea seeds through computerized image analysis, using the Seedling Analysis System (Sistema de Análise de Plântula - SAPL®) as a basis. Two chickpea cultivars were evaluated, consisting of five seed lots of cv. BRS Aleppo and four seed lots of cv. Cícero. Test were performed on the seeds of each cultivar for initial characterization of the physiological potential of the lots, and the results were compared with the determinations made via SAPL®. The results showed high correlations between the variables obtained from computerized analysis and from traditional vigor tests, especially for the close relationship between the cold test and low temperature germination test with the corrected vigor index (r > 0.9) evaluated on the fourth day after the beginning of the test. The total length of seedlings, length of the primary root, and growth and corrected vigor indices obtained through computerized analysis of seedlings on the 4th day after sowing allowed separation of the lots regarding vigor. Computerized analysis of seedlings using SAPL® is effective in determining the vigor of chickpea seed lots.

“…Image analysis of seeds and seedlings in agriculture is one potential technique which is widely used in research. This technique aside not been destructive also helps to relates attributes of seed morphology to seedling performance, which ultimately expresses seed vigor with greater precision and less subjectivity (Vasconcelos et al, 2018;Medeiros et al, 2019). The different metric measurements on seeds are very essential quantitative variables for determining the size and shape of seeds (Arapa-Carcasi and Padrón-Pereira, 2014).…”

Digital seed imaging was utilized in this study to evaluate the morphometric characteristics of pigeon pea for genotype discrimination. One hundred seeds in each of the pigeon pea accession were subjected to digital imaging analysis using the WinSEEDLE™ software to differentiate the seed metric characters. Seeds were placed on a lighting hood and were automatically analyzed by the scanner and the image of the seed was recorded by the WinSEEDLE™. The procedure was repeated three times. The parameters observed were projected area, straight length, curve length, straight width, curve width, volume circle, and projected perimeter. Data collected were subjected to analysis of variance, principal component analysis and product moment correlation coefficients between the parameters were obtained. The result revealed that the pigeon pea accessions were highly variable in all the seed metric traits evaluated. Accessions NSWCC-34 and NSWCC-32 showed superiority values in most of the seed metric traits evaluated. Accessions NSWCC-32 had 28.35 mm2 , 6.99 mm, 7.37 mm, 5.23 mm and 5.28 mm in seed projected area, seed straight length, curve length, straight width and curve width, respectively while NSWCC-34 recorded 28.34 mm2 , 6.75 mm, 7.10 mm, 5.22 mm and 5.27 mm for the same evaluated traits. Most of the seed traits showed significant positive and strong association. The study, therefore, recommends that accessions NSWCC-34 and NSWCC-32 as well as those traits with high contribution to the major variation (seed projected area, seed straight length, curve length, straight width, curve width and volume circle) could be included in the seed improvement programme for improved seed quality in pigeon pea.

“…In order to aid the decisions process regarding the destination of seed lots and to identify differences in performance of the same, it is necessary an evaluation of the physiological potential of the lot. Such evaluation is usually performed through germination tests and measurement of the length of the seedlings and their parts (Medeiros et al, 2019).…”

Image analysis for the evaluation of soybean seeds vigor

The search for time and human subjectivity reduction in the analysis of the physiologic potential of seeds has brought forward the use of computerized systems as an alternative. The goal of this research was to assess the effectiveness of the GroundEye equipment in the characterization of soybean seeds vigor by using the image analysis technique in comparison to the information provided by vigor tests recommended to soybean seeds. Sixteen lots of two soybean varieties were used — variety 98Y12 and P98Y70, characterized by the following tests: germination test, accelerated ageing test, cold test, tetrazolium test, and seedling emergence in the field. The image analysis was performed using the GroundEye software to obtain the vigor index and the average length of seedlings and roots for a later comparison with the results of the accelerated ageing test and the manual measurement of the average length of seedlings and roots. GroundEye has demonstrated efficiency in the determination of vigor of soybean seeds and has reduced the time needed to obtain the results in six days, being indicated in the quality control programs established by soybean seeds production companies.
