“…Comparison of the variables evaluated shows that the equations are fitted in a satisfactory manner because the results estimated generally have the same tendency as the results obtained. Matera et al (2019) worked with soybeans seeds and also found accuracy among the variables evaluated -most prominently for the electrical conductivity and percentage of seedling emergence in the field tests, with accelerated aging as the dependent variable. Table 5 also shows that the lowest values of leaching Table 5.…”

“…The results of the electrical conductivity test showed strong negative correlation with the tests of germination (r = -0.81), tetrazolium vigor (r = -0.84), accelerated aging (r = -0.86), first germination count (r = -0.78), seedling emergence in the field (r = -0.79) and seedling emergence in sand (r = -0.85) ( Table 3). Barros and Marcos-Filho (1997), Barbieri et al (2013), Schuab et al (2006) and Matera et al (2019) worked with soybean seeds and also found strong negative correlation between the electrical conductivity test and the tests of germination, accelerated aging and seedling emergence in the field. This is a strong indication that the test can and should be part of programs for quality control of soybean seeds, considering that such programs should always work with more than one procedure, thus assisting in decision making regarding the use of seed lots.…”

Electrical conductivity (EC) stands out among vigor tests because of its capability of detecting damage in seeds in the initial stage, since EC is related to disorganization of the cell membrane. The aim of this paper was to study use of the EC test as an alternative for vigor evaluation in soybean seeds, verifying its relationship to different vigor tests and thus suggesting values and the range of values of electrical conductivity that indicate the performance potential of a seed lot in the field. Eleven seed lots from each of four soybean cultivars were used for this study. The moisture level was determined and the following tests were performed: electrical conductivity, germination, tetrazolium, accelerated aging, first germination count, seedling vigor classification and emergence of seedlings in the field and in sand. The EC test had a significant and negative correlation (p < 0.01) with all the tests performed. Linear regression analysis allowed separation of the seed lots into classifications of very high vigor (EC ≤ 70 μS.cm-1.g-1), high vigor (EC from 71 to 90 μS.cm-1.g-1), medium vigor (EC from 91 to 110 μS.cm-1.g-1) and low vigor (EC ≥ 111 μS.cm-1.g-1).

“…An analysis of the effect of localities and climatic conditions on seed quality and viability in different soybean genotypes was conducted by Vujaković et al (2011a), who showed that the quality and vigour of seeds were influenced by genotype and agro-ecological conditions in soybean seed production. The accelerated ageing test can be used to obtain data on the physiological quality of seeds, predict germination in the field, and assess seedling vigour, or as an aid in the interpretation of soybean seed lot vigour (Matera et al, 2019).…”

“…A database containing information and visual characteristics of soybean seeds classified according to the types and intensity of damage obtained by the tetrazolium test was published by Pereira et al (2019). The set of these data enables an efficient way of automatic definition of soybean seed vigour through machine learning and data collection methods, which can be useful for researchers, seed analysts and farmers.…”

Seed vitality and vigour are the two most common parameters related to seed quality. It is crucial to have reliable methods and tests for seed quality and seed vigour testing. The standard germination test can be used to predict field emergence, but laboratory seed testing conditions are often in conflict with field conditions. Validated tests for vigour evaluation in legumes are the conductivity test, the accelerated ageing test and the tetrazolium test. Also, other types of vigour tests have been used to solve different problems in the seed sector. The modern approach, the computerised image analysis of legume seeds and sprouts, based on interactive and traditional methods, is a promising alternative for vigour determination.

“…For this it is necessary to carry out vigor analysis tests and currently, there are numerous methodologies. However, it is known that the accelerated aging test is one of the most used for soybean crops, as it provides a high level of stress to the seeds, with high temperature and high humidity (MATERA et al, 2019).…”

Seed companies use vigor tests in their internal seed quality control procedures. Therefore, it is necessary to choose effective methods to obtain quick responses for making decisions related to the handling, disposal and marketing of seed lots. Thus, the objective of this work was to adapt a methodology for the accelerated aging test in soybean seeds. Sixty-nine lots were used and the experimental design used was completely randomized, with four replications. For the initial characterization of the lots, water content was determined, germination test and field emergence. The soybean seed lots selected based on the initial characterization, were submitted to the standard accelerated aging methodology and twenty-one adapted methodologies. After the physiological characterization of the 69 lots, 24 lots with similar germination with different levels of vigor were selected. For adapted methodologies that used only distilled water inside the gerbox box, there was an increase in the water content of the seeds of all analyzed lots. However, all methodologies with the use of saline solution had alower water content. The adapted methodologies N (pre-treatment in forced air oven at 35-40°C for two hours, BOD 42°C for 24 hours, using saline) and S (pre-treatment in forced air oven at 35-40°C for two hours, BOD 45°C for 12 hours, with the use of distilled water) are the most suitable for use in the accelerated aging test for soybean crops, as they present relevant results in a shorter evaluation period.
