The use of appropriate management practices, such as sowing and fertilizing, associated with the use of promising genotypes are strategies for obtaining bean seeds of high quality. The aim of this study was to evaluate the physiological quality of cultivars of common bean seeds produced in two growing seasons under different phosphorus levels. The experimental design was completely randomized in a factorial design of 2 × 2 × 6, with four replications. We evaluated two common bean cultivars (‘IAC Carioca Precoce’ and ‘IAC Carioca Tybatã’), two planting seasons of common beans (rainy season and dry season), and six rates of phosphorus fertilization (0, 30, 60, 90, 120, and 150 kg ha-1 of P2O5) applied to the planting rows, using triple super phosphate as the source of P. Seed quality was evaluated by testing the water content, germination, first account of the germination test, accelerated aging test and the water content after the test, electrical conductivity, and seedling emergence in the field. Data were subjected to analysis of variance and the means of cultivars and growing seasons were compared using Tukey’s test at 5% probability. Regression analysis was performed for phosphorus levels. Seeds of ‘IAC Carioca Precoce’ produced during the rainy season showed higher germination. In the dry season, the highest seedling emergence in the field was recorded for ‘IAC Carioca Tybatã’. Common bean cultivation provided seeds with higher germination and vigor in the dry season than in the rainy season. The accelerated aging test showed that when phosphorus was applied in the planting rows, the vigor of common bean seed was enhanced, with a better response to higher doses when cultivated in the dry season.

Although the accelerated aging test is widely used to determine seed vigor, there are methodological variations in seed exposure time at 41 °C. Therefore, the objective was to indicate the most appropriate seed exposure time to segregate lots that also exhibits a correlation with seedling emergence in the field, and establish vigor levels using the aforementioned test. Soybean seed samples were collected at pre-sowing, representing 100 lots in the 2016/2017 growing season and 125 lots in the 2017/2018 season from different warehouses in 4 regions of Santa Catarina state (SC). Physiological quality was evaluated by germination, accelerated aging (24 and 48 h at 41 °C) and field emergence tests. The results were submitted to descriptive statistical analysis and Pearson’s correlation analysis (p < 0.05). The rank sum index, associated with the Scott-Knott clustering method, was used to classify physiological quality. The average germination percentage was 90 and 91% in the 2016/2017 and 2017/2018 growing seasons, respectively. Vigor obtained an average of 86 (2016/2017) and 85% (2017/2018), when seeds were submitted to accelerated aging for 48 h, and 89% (both seasons) for 24 h. In regard to field emergence, the average was 85 and 80% in the 2016/2017 and 2017/2018 growing seasons, respectively. Considering the 225 lots, the greatest correlation with field emergence was observed in vigor - 48 h (r = 0.71 p < 0.05). Rank sum classification made it possible to establish vigor-based categories, whereby batches with over 85% vigor by 48-h accelerated aging were classified as high vigor, 70 to 84% medium vigor, and under 70% low vigor.

Tetrazolium Test

Seed deterioration causes losses to seed companies during the storage. For researches, the challenge has been to develop techniques which improve the seed longevity as well as laboratory analysis methods required for evaluating the evolution of deterioration in storage. This study had the objective of determining the effectiveness of the accelerated aging test with a saturated NaCl solution and Seed Vigor Imaging System (SVIS) analysis in checking soybean seed physiological in comparison with the recommended vigor tests. Soybean seeds from the cultivars BRS 184 and M-Soy 7908 RR were used, each of them were represented by six lots and stored for six months under two environment conditions. Seed physiological quality was checked every two months in storage through germination evaluations, accelerated aging (different methods), tetrazolium test (vigor and viability) seedling emergence, and SVIS analysis. The tetrazolium test is the most advisable method for evaluating soybean seed quality during storage. The results of the saturated salt accelerated aging test with NaCl at 41 ºC for 72 or 96 hours and the SVIS evaluation are also both efficient for estimating the physiological potential of seeds.

The Relationship

With the aim of studying the relationship between the physiological quality of soybean seeds submitted to three harvest times and seedling emergence in the field, seeds of cultivars UFV-16, Splendor, Vencedora, Confiança, UFV-18, UFV-TN 105, Garantia and Celeste were harvested at stages R8, R8+15 and R8+30 days. The following tests were performed: accelerated aging, electrical conductivity, emergence in sand, emergence speed index and seedling emergence in the field. Germination and vigor were reduced in seeds harvested at 30 days after stage R8 in all the tests, except for the accelerated aging test, which showed a decline in vigor seeds harvested with a delay of 15 days. Seeds of cultivars UFV-16, Confiança and Garantia showed lower physiological quality in most tests, while the seeds of cultivar Celeste had higher physiological quality than the others. There was similarity between the test results of seed quality and seedling emergence in the field.

Chia (Salvia hispanica L.) is a plant native to central and western Mexico and northern Guatemala belonging to the Lamiaceae family, well known for its seeds containing antioxidants, dietary fibers, and ?-linolenic acid, which helps to prevent different diseases, such as diabetes, obesity, cancer and Alzheimer. In Brazil, there is not much information about the crop, mainly about the physiological quality of its seeds. Therefore, the objective was to establish vigor testing methods to evaluate the physiological quality of chia seeds. Five seed lots were used, in which germination tests, seedling emergence, emergence velocity index and variations in the electrical conductivity test were carried out. The volume of distilled water was 25 and 50 mL, the number of seeds was 50 and 100, the temperature was 20, 25 and 30 °C, the soaking period was 1, 2, 4, 6, 12, 18 and 24 hours and variations in there was accelerated aging test by the traditional method and saturated NaCl solution, being periods of aging as 24, 48, 72 and 96 hours and temperatures of 38, 41 and 44 °C. It is concluded that both the electrical conductivity test and the accelerated aging test are efficient in evaluating the physiological quality of chia seeds. The electrical conductivity test must be performed with 100 seeds in 50 mL of distilled water, for four hours soaking at 25 or 30 °C; and the accelerated aging test should be performed at 44 °C for 24 hours by the traditional method or 41 °C for 24 hours using saturated NaCl solution.

Accelerated aging is one of the most useful tests used for the evaluation of seed vigor but it is seldomly used to test melon (Cucumis melo L.) seeds. The objective this research was to compare different procedures of the accelerated aging test to evaluate the physiological quality of melon seeds and the efficiency of using saturated salt solution for the control of water uptake by seeds. Five seed lots each of the hybrids AF-646 and AF-682 were tested for germination, seedling emergence, traditional accelerated aging (periods 0f 48, 72 and 96 hours, at 38 or 41°C) and salt saturated accelerated aging. The accelerated aging test (traditional procedure and with salt solution) for 72h and 96h, at 38 or 41°C was sensitive to detect differences in the physiological quality of the seeds. It was also observed that the seed water content after salt saturated accelerated aging was lower and more uniform, thus presenting advantagens in relation to the traditional procedure.

ABSTRACT The accelerated aging test consists of evaluating the vigor of the seeds under conditions of high temperature and humidity, with the purpose of identifying the physiological quality of lots with similar germination. The objective of this study was to evaluate the efficiency of the accelerated aging test for classifying seed lots of P. moniliformis at different levels of vigor. Initially, the seed lots were assessed by means of seedling emergence, life velocity index, shoot length and root length, total dry mass of seedlings and determination of water content, before and after each period of aging. The experimental design for the whole world was based on a 3 × 4 factorial scheme (three seed lots and four periods of 24, 48, 72 and 96 h duration), with separate evaluations at temperatures of 38 °C and 41 °C. The accelerated aging test conducted at a temperature of 41 °C for 24 h was a more suitable combination for separating batches of P. moniliformis according to different levels of vigour, and made it possible to obtain results similar to the classification of lots in relation to the initial quality.

Abstract: This work evaluated the efficiency of accelerated aging test to determine the physiological potential in treated soybean seeds with fungicides and insecticides, in addition to analyzing the concordance between the results obtained by different accelerated aging methods with the actual results of the physiological quality in seeds after the storage. The study was divided into two experiments, both with entirely randomized delineation, with four replications. In the first experiment, seed germination was evaluated after imposing some treatments that were arranged in a 3 x 2 x 3 factorial scheme: seed treatment (imidacloprid + thiodicarb; fipronil + thiophanate methyl + pyraclostrobin; no treatment); vigor levels (high; low); and accelerated aging (traditional; saturated NaCl solution; no aging). In the second experiment, seedling emergence was evaluated after applying some treatments that were arranged in a 3 x 2 x 2 factorial scheme: seed treatment (imidacloprid + thiodicarb; fipronil + thiophanate methyl + pyraclostrobin; no treatment); vigor levels (high; low); storage time (0 and 135 days). The accelerated aging methods were efficient to determine the physiological potential of the seeds, in which, the NaCl method presented better results. The physiological potential of soybean seeds decreased throughout storage and the application of chemicals in seed treatment impaired the germination and emergence percentages, regardless of the active ingredient used. The accelerated aging method with NaCl presents greater agreement with the actual storage results.

The physiological quality of seeds is commonly characterized by the germination and vigor, which can be defined as the sum of attributes that confers the potential for seeds to germinate, rapidly emerge and result in normal seedlings under a wide range of environmental conditions. The purpose of the study was to test alternative methodologies for the accelerated aging test to evaluate the physiological potential of poppy seeds. Samples obtained from four batches were subjected to germination test at a temperature of 20 °C, traditional accelerated aging and accelerated aging diluted with saline solution (11 g of NaCl  in 100 mL-1  of water) using three temperatures, 41 °C, 42 ºC and 43 ºC , for periods of 12 and 24 hours. The percentage of germination, the rate of emergence velocity, performed together with the emergence speed and the percentage of seedling emergence test were evaluated. It is concluded that the methodology of traditional accelerated aging with temperature of 43 °C and period of 12h shows to be promising for the verification of the physiological quality of poppy seeds.

The physiological quality is based on the genotype and may be accompanied since the first stages of selection through the study of genetic diversity. The purpose of this study was to evaluate the parental genetic contribution in the seed physiological quality in corn intervarietal crossbreeds. The intervarietal crossbreeds were performed using landraces genotypes, open pollinated varieties and commercial hybrids. The seeds obtained from the crossbreed, their equivalents and parentals were evaluated regarding their water percentage, germination, germination speed rate, accelerated aging, field emergence and electrical conductivity. The seeds obtained in the crossbreed are viable and vivid with heterosis when compared with the parentals. The accelerated aging test was more effective for selecting the strongest genotypes. The canonical variables were useful to group the genotypes that presented similar physiological characteristics. The genotypes MPA 01 x Pixurum 05, MPA 01 x AS1565, MPA 01 x SJC5886, SJC5886 x Pixurum 05 and Fundacep 35 x SCS 154 Fortuna were the best crossbreeds regarding the production of better physiological quality seeds.

Moisture Conditions

Laboratory vigour tests were performed on seed from 4 soybean [Glycine max (L.) Merr.] cultivars coming from commercial crops grown in eastern Australia. The seed from each cultivar had greater than 80% germination and a range in vigour. Vigour tests consisted of the accelerated aging (with or without a seed protectant, Thiram), cold, saturation and hypocotyl length tests. Results were compared with seedling emergence from the same cultivar when planted under growth room conditions (25/20 � 1�C, 14/10 h day/night) at 3 seedbed moisture levels (field capacity, -0.01 MPa; dry, -0.30 MPa; and saturated soil, soil saturated for 48 h, planted then allowed to dry to field capacity). The modified accelerated aging test with Thiram was significantly (P<0.01) correlated with emergence in all 3 seedbed moisture conditions. High vigour seed samples with high accelerated aging germinations emerged well. Overall, the vigour test which ranked the seed samples to give the best indicator of performance under a range of seedbed moisture conditions was the modified accelerated aging test with thiram.
