The use of healthy and vigorous seeds is necessary to ensure adequate plant stands, therefore, vigor tests are used to measure the physiological potential of seeds alongside with the germination test. The objective of this study was to evaluate different procedures for the estimation of the physiological potential of eggplant seeds through the accelerated aging test. Seed lots were tested for moisture content, germination, first count of germination, seedling emergence and speed of emergence index. Then, seeds were subjected to the conventional accelerated aging test, using an unsaturated NaCl solution or a NaCl saturated solution, for 24, 48 and 72 hours at 41 °C, estimating the moisture content after each period of aging. The treatments were allocated in a completely randomized design, with four treatments (seed lots) and four replicates. The use of the saturated solution of NaCl decreases the absorption of water and the rate of deterioration of eggplant seeds during the accelerated aging test, providing more uniform results. The accelerated aging test allows eggplant seed lots from cv. Napoli to be ranked at different levels of vigor and, among the procedures tested, the combinations 41 °C/48 hours and 41 °C/72 hours allowed the proper assessment of the physiological potential of seeds of this cultivar.

Abstract:Niger is a promising oilseed species for biodiesel production but there is no much information about the physiological potential of its seeds. Thus, the aim was to adapt the methodologies of accelerated aging test on six lots of niger seeds. The test was carried out by traditional and with saturated salt solution (20 and 40 g NaCl.100 mL-1) methods at 41 and 45 °C for 24, 48, 72 and 96 hours. After the decay period, the seeds were submitted to the germination test, proceeding to an evaluation on the seventh day after sowing, counting the normal seedlings percentage. A completely randomized design with four replications of 50 seeds was used and the means were compared by Tukey's test. The accelerated aging test was correlated with seedling emergence and provided lots classification in at least two levels of vigor. For the accelerated aging test, the method with 20 g NaCl.100 mL-1 at 41 °C for 24 hours is recommend. The traditional method is not suitable because it provides water content variation between samples above what is tolerable.

ABSTRACT: This study aimed to determine the most appropriate method to assess the sunn hemp ( Crotalaria juncea L.) seed vigor in the accelerated aging test. Five seed lots from harvest 2007/2008 were evaluated for germination, vigor and seedling emergence in the field. Accelerated aging test was performed at 41°C during 48, 72 and 96 hours, with and without sodium chloride saturated solution. Then, the promising procedure was also performed for 2008/2009 and 2009/2010 harvests. In the traditional accelerated aging test, the no-uniform water acquisition by the seeds adversely affected results. Accelerated aging test with sodium chloride saturated solution is the most appropriate method to evaluate the physiological potential of sunn hemp seeds, and the combination of 41°C and 96 hours is efficient for separating of seed lots in different vigor levels.

The aim of this study was to evaluate the effects of Brachiaria seed contact time with 05-25-15 fertilizer (N-P2O5-K2O) on the seed’s physiological quality. The experimental design was a completely randomized design with four replicates. Treatments were arranged in a 5x4 factorial, being: five seeds contact times with fertilizer (0, 24, 48, 72 and 96 hours); four forages: Marandu palisadegrass, Piatã palisadegrass, Xaraés palisadegrass and Ruziziensis grass. The performed tests were: water content, germination (first count and germination percentage), tetrazolium (viability), electrical conductivity, accelerated aging, sand emergency and emergence speed index. Contact time of 05-25-15 fertilizer with Brachiaria seeds reduces linearly: Germination, emergence and emergence speed index of Brachiaria seeds; Piatã and Xaraés palisadegrass seeds viability; vigor (electrical conductivity), except in Ruziziensis grass seeds; and seeds germination of Piatã palisadegrass submitted to accelerated aging test (vigor). Piatã palisadegrass is the least recommended, among the analyzed grasses, for intercropping in simultaneous sowing.

Abstract: Despite the insufficient internal supply of popcorn kernel cultivars, the Brazilian production is continuously increasing. Therefore, searching for tests that offer fast results and reliable information on the physiological potential of the seeds is very important. The objective of this study was to assess the efficiency of the accelerated aging test, by using different times and exposure temperatures, for the evaluation of the physiological quality of popcorn seed lots. Popcorn seeds from three lots of the hybrid AP 8203 were used. For the initial characterization of the lots, the following tests were conducted: seed moisture content, first and final germination count, and field emergence. The accelerated aging test was performed in a 3x4x2 factorial scheme. After aging, the seeds were tested for moisture content, germination, and electrical conductivity. The experiment was carried out in a completely randomized design. The characteristic vigor was affected during aging, as evidenced by the increase in the amount of leachate detected by the electrical conductivity test. Seed lot 3 was most vigorous in the aging test conducted for 48 h at 45 °C. The accelerated aging test at 42 ºC for 48 h provides consistent information to differentiate seed lots of popcorn.

Vigor tests are very important to obtain additional information to the standard germination test and can assist in decision-making. The aim of this work was to evaluate accelerated aging test methodologies for the determination of vigor in tobacco seeds. For the study, ten seed lots of tobacco were used. The initial quality of the tobacco seeds was determined through the germination test, first count of germination, germination speed index, seedling emergence at 7, 14 and 21 days after sowing, emergence speed index and the accelerated aging with water performed as proposed by the Association of Official Seed Analysts. After the determination of seed initial quality, the accelerated aging test was studied in the following methods: accelerated aging with water, saturated saline solution (40g NaCl 100mL-1 water) and unsaturated saline solution (11g NaCl 100mL-1 water), submitted to the temperatures of 45 and 41°C, for the exposure periods of 24, 48 and 72 hours. According to the results obtained, the accelerated aging test with water conducted under a temperature of 45°C combined with a 24-hour exposure period is shown as adequate for evaluating the vigor of tobacco seeds.

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: The aim of this study was to adjust the accelerated aging test to evaluate the physiological potential of seed lots of Brachiaria brizantha ‘Xaraés’, represented by four lots. Seeds were tested by traditional accelerated aging and with saturated NaCl solution in five aging periods: 0, 24, 48, 72 and 96 hours. The profile of the lots was determined by the following measures: moisture content, germination test, first germination count, germination speed index, initial stand, emergence, and emergence speed index. The accelerated aging test makes it possible to separate the lots by the method of saturated NaCl solution for 24 hours and it is appropriate for evaluation of seed physiological potential.

Abstract: This study evaluated the physiological potential of soybean seeds harvested during two seasons, on different maturation stages and subjected to different drying temperatures. The seeds were harvested at the maturations stages R7, R7 + 2, R7 + 3, R7 + 5, R7 + 6, R7 + 7, R7 + 10 and R7 + 12 days (55, 50, 45, 40, 35, 30, 25, and 20% of moisture content). For each maturation stage, seeds were divided into three samples: one sample was used to directly evaluate the physiological potential, and the others were dried at 40 °C and 50 °C, until reaching the moisture content of 11.5%. The physiological potential was evaluated through germination test, first germination count of germination, accelerated aging, modified cold, electrical conductivity and seedling emergence. The maximum physiological potential of seeds is achieved at the moisture content of 55%, the point that the dry matter is maximum. The seeds became tolerant to artificial drying approximately at the stage R7 + 7 days (30% of moisture content). Germination and vigor of the soybean seeds reduce as the drying temperature is increased from 40 °C to 50 °C, and this effect is enhanced when the seeds show moisture contents above 30%.

International research on vegetable seed vigor is not at the same level attained for grain crops species. This study was conducted to identify reliable procedures for the accelerated aging and controlled deterioration tests to rank onion (Allium cepa L.) seed lots according to their physiological potential. Six seed lots of the cultivars Aurora and Petroline were evaluated in the laboratory for germination, first count, seedling vigor classification, traditional and saturated salt accelerated aging (41ºC / 48 and 72 h), controlled deterioration (24% of water / 45ºC / 24 h) and seedling emergence tests. Seed moisture content after the saturated salt accelerated aging test was lower and uniform, which is considered an important advantage in comparison to the traditional procedure. The saturated salt accelerated aging (41ºC / 48 and 72 h) and controlled deterioration (moisture content adjusted to 24% / 45ºC / 24 h) tests were the best procedures to assess the physiological potential of onion seeds, and are indicated for use in quality control programs.
