“…Santos and Rossetto (2013) found similar results using those same parameters for crambe seed lots differentiation of FMS Brilhante cultivar. In contrast, Leão-araújo et al (2017) observed the efficiency in seedling length tests made by computerized analysis system using Vigor-S® to detect differences in physiological quality of crambe seed lots.…”

Vigor tests are important mainly to identify differences associated to lots performance in field conditions. The objective of this study was to define the most appropriate tests to evaluate the crambe (Crambe abyssinica) seeds vigor. Seven seed lots of crambe were subjected to the standard germination (on the first and last count), germination speed index (GSI), primary root protrusion speed index (PRPSI), seedling length dry and weight seedling, water stress test using PEG 6000 at -0.2 MPa, electrical conductivity and cold test without soil. Crambe lots studied had germination percentages varying from 54 to 80.5%. The GSI, on the first count of water stress and electrical conductivity test ranked lots between two vigor classes The PRPSI, seedling length, seedling dry weight and last count of water stress tests were less sensitive to evaluate vigor for crambe seed. The cold test without soil and the first count of standard germination test were capable to dishtinguish lots more efficiently than the standard germination test on last count by ranking four of the seven seed lots studied.

“…In the same manner, Silva et al (2012) concluded that seedling length and the vigor and growth indices obtained in analysis through the Seed Vigor Imaging System (SVIS®) were effective in classification of eggplant seed lots. Leão-Araújo et al (2017) indicated that the indices generated uisng SVIS®, including uniformity in seedling development, were able to effectively separate crambe seed lots.…”

Phytotoxicity in soybean seeds treated with phytosanitary products at different application times

Due to increased use of treated seeds, studies are necessary in relation to the effects of the treatments and their possible consequences on seed quality. The aim of this study was to evaluate phytotoxicity according to when phytosanitary products are applied on soybean seeds and their effect on seed physiological quality and field performance. A completely randomized experimental design was used in a 9 × 2 factorial arrangement involving 9 seed treatments (fungicides and insecticides) and two application times (60 days before sowing and at the time of sowing in the field). Moisture content was determined and tests were performed to ascertain physiological quality (germination and germination under water restriction). Root and hypocotyl length, seedling length, and vigor and uniformity indices were evaluated with the assistance of Vigor-S®. In the field, the following determinations were made: plant height at 30 and 60 days after emergence, first pod height, number of pods per plant, number of seeds per pod, and yield. Early seed treatment in the soybean crop can affect initial development of the plants, but it does not affect yield. The phytotoxicity caused by the soybean seed treatment was observed in the root length characteristic.

“…This index is relevant since irregular seedling emergence can lead to delays in development and variations in growth of plants in various phenological stages, which also affects harvest results (Marcos-Filho, 2016). Leão-Araújo et al (2017) indicated that the indexes generated using the Seed Vigor Imaging System (SVIS ® ), including uniformity of seedling development, were able to separate crambe seed lots in an effective manner. Results obtained by Silva et al (2012) showed that uniformity of seedling development can provide useful information regarding the degree of seed deterioration, initial growth potential, and uniformity of seedling emergence of crotalaria.…”

“…possibility of using information from the indexes generated from development of seedlings to evaluate seed vigor (Leão-Araújo et al, 2017). The use of Vigor-S ® for computerized analysis of seedling images allowed the physiological potential of seeds to be evaluated through more than one parameter, which shows the possibility of taking better advantage of the results obtained from the same evaluation.…”

“…The use of software that employs the seedling image analysis technique to make inferences regarding seed quality has been studied and recommended for various species, such as squash (Silva et al, 2017), onion (Gonçalves et al, 2017), carrot (Marchi and Cicero, 2017), crambe (Leão-Araújo et al, 2017), soybean (Medeiros and Pereira, 2018;Wendt et al, 2017), common bean (Gomes-Junior et al, 2014), and maize (Castan et al, 2018), among others. However, there is not yet information that shows the effectiveness of Vigor-S® for evaluating common bean seed vigor (Phaseolus vulgaris L.).…”

Assessing the physiological quality of common bean seeds using the Vigor-S® system and its relation to the accelerated aging test

et al. 2019

Automated analysis of seed vigor stands out by allowing greater accuracy, standardization, objectivity, and speed in evaluation of the physiological potential of seed lots. The objective of this study was to evaluate the efficiency of the Vigor-S® system in assessing the physiological quality of common bean seeds compared to the information provided by the traditional vigor tests recommended for this species. Four genotypes of common bean were used, each one represented by four seed lots. Characterization of the physiological potential of the lots was carried out by the following tests: germination, first count of germination, seedling emergence, accelerated aging, and electrical conductivity. The results of these tests were compared with the data obtained from the image analysis technique, specifically the Vigor-S® system, which was used to evaluate seedling growth at two, three, and four days after the beginning of the germination test. Shoot length, primary root length, and seedling length were measured, as well as the growth index, uniformity index, and vigor index were calculated. Computerized analysis of seedling images using the Vigor-S® software is a reliable alternative for evaluation the physiological potential of bean seeds, and it produces information similar to evaluations traditionally used for that purpose.
