Abstract: The evaluation of seed vigor through image analysis has been gaining space in quality-control programs due to its easy use, objectivity, and speed. This study aimed at assessing the computer image analysis of seedling as a method for evaluate cottonseed (SVIS®), and compare it with tests traditionally employed for the same purpose. The experiments used cottonseeds of the cultivar FM975WS. First germination count, accelerated aging, low-temperature germination, emergence in sand and emergence-in sand speed index, seedling emergence in the field, and computer analysis were used to evaluate the seed vigor. The results showed that performing the computer image analysis with the software SVIS® is a viable alternative to assess the vigor of cottonseeds.

Abstract: The computerized image analysis of seedlings constitutes an efficient technique to evaluate the quality of seed lots, since it is quick in responding, has a simple execution and reproduction. The goal of this research was to verify the efficiency of the computer image analysis of seedlings to detect vigor differences among broccoli seed lots and compare them with other traditionally used vigor tests. Computerized image analysis were performed by the Seed Vigor Imaging System (SVIS®), using 3-day-old seedlings and the results were compared to germination at first count, seedling emergence, accelerated aging and electrical conductivity tests. Evaluations were performed in three experimental periods (before storage, 6 and 12 months of storage at 20 °C and 45-50% RH). A completely randomized design with eight replications of 25 seeds was used. Data were submitted to analysis of variance and means were compared by Scott-Knott test at 5% error probability. It is concluded that it is possible to detect vigor differences among broccoli seed lots by the computerized image analysis of seedlings with SVIS®, similarly to traditional vigor tests.

Seed vigor testing is an important component of quality control programs adopted by seed industry. The software Seed Vigor Imaging System (SVIS) has been successfully used for seed vigor assessment in different species. The objective of this research was to verify the SVIS efficiency to assess okra seed vigor in comparison to other vigor tests used for this species. Five seed lots of 'Clemson Americano' and four of 'Santa Cruz' were submitted to germination (speed and percentage), cold germination (speed and percentage), traditional and saturated salt accelerated aging (41 ºC/72 and 96 h) and seedling emergence tests during 12 months storage. Vigor index, uniformity of growth and seedling length were determined by the software Seed Vigor Imaging System (SVIS). Results showed that the vigor index and seedling length determined by the SVIS analyses are efficient to determine okra seed vigor as well as the accelerated aging test (41 ºC/72 h).

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.

Abstract: The aim of this study was to verify the possibility of using computerized seedling image analysis to detect differences in vigor among onion seed lots and to compare this analysis with traditional vigor tests. We used five seed lots of two onion cultivars, Bella Catarina and Bella Vista. The Seed Vigor Imaging System (SVIS®) software was used to process the seedling images and assess seedling length and vigor through seedling uniformity and growth indexes. These determinations were compared to traditional tests used to evaluate onion seed vigor: germination percentage and first germination count, seedling emergence percentage and emergence speed, accelerated aging, and electrical conductivity. Results showed that vigor differences among onion seed lots can be identified using the SVIS® in a manner similar to traditional vigor tests; assessments should be performed at five days after sowing.

The assessment of physiological potential is essential in seed quality control programs. This study compared the sensitivity of different procedures for evaluating super sweet corn seed vigor, focusing on the primary root protrusion test. Six seed lots, each of the SWB 551 and SWB 585 hybrids, were used. Seed physiological potential was evaluated by germination and vigor tests (speed of germination, traditional and saturated salt accelerated aging, cold test, seedling length, seedling emergence and primary root protrusion). Primary root protrusion was evaluated every 12 hours at 15 °C, 20 °C and 25 °C using two criteria (primary root protrusion and seedlings at the 2 mm root stage). It was concluded that the primary root protrusion test at 15 °C can evaluate super sweet corn seed vigor by counting the number of seedlings at the 2 mm root stage.

Germination and vigor tests are essential components of seed quality control programs adopted by seed industries. We studied different procedures to perform the controlled deterioration test to identify differences in vigor among okra seed lots. Four seed lots of Colhe Bem cultivar and five seed lots of Santa Cruz 47 cultivar were submitted to the following tests: germination, seedling emergence, controlled deterioration (seeds with moisture contents of 18, 21 and 24% at 45°C for 24 and 48 hours) and moisture content. The controlled deterioration test is efficient to evaluate the physiological potential of okra seeds, and the combination of 24% water, 45°C during 24 hours is recommended.

Abstract: The search for tests that offer fast and reliable information on the physiological potential of seeds is of fundamental importance for quality control programs. The aim of this study was to evaluate the efficiency of the potassium leaching test in identification of different vigor levels of popcorn seed lots. Five seed lots of the hybrids AP8203 and AP4512 were tested for moisture content, and physiological quality was evaluated by tests of germination, first count of germination, and seedling emergence in the field. These results were compared to variations in the potassium leaching test (temperatures of 25 °C and 30 °C, volumes of 50 mL and 75 mL of water, fifty and one hundred seeds, and periods of 0.5 h, 1 h, 1.5 h, 2 h, 2.5 h, 3 h, 4 h and 5 h). Results showed that the potassium leaching test is efficient in separating the popcorn seed lots regarding physiological potential, and the most adequate conditions for this test are the use of fifty seeds with 50 mL of water for two hours at 30 ºC.

The assessment of seed physiological performance is essential to provide consistent information to compose quality control programs conducted by seed companies and allow prompt decisions to reduce post-harvest and commercialization problems. This research was carried to evaluate the efficiency of different procedures to determine cauliflower seed vigor. Six lots of the cultivar Sharon were initially characterized by germination and seedling emergence, and subsequently subjected to traditional and saturated salt accelerated aging, controlled deterioration, electrical conductivity, and potassium leachate tests, in two evaluation times. The traditional accelerated aging (41ºC/48 h), the saturated salt procedure (45ºC/72 h), the controlled deterioration (moisture content adjusted to 20% or 22% and aging at 45ºC/24 h), the electrical conductivity (50 seeds/75 mL water and evaluation after 4 h) and the potassium leakage (25 seeds/50 mL of water and evaluation after 30 min) laboratory tests are sensitive to detect differences in the physiological potential of cauliflower seeds. However, those results did not relate to the percentage seedling emergence in greenhouse controlled conditions, as a consequence of the favorable conditions for emergence. However, the differences identified in the tests may be related to the ability of seed lots to perform in less favorable environments.

ABSTRACT: This study aimed to associate two concepts of seed vigor testing, the aging and seedling growth using image analysis, providing a feasible and time-saving way to evaluate maize seed vigor in large scale. For this purpose, five seed lots with different vigor levels from two single hybrids were used. The seeds were characterized by moisture content, germination, seedling emergence, seedling emergence speed index, accelerated aging and cold tests. The treatments were composed by varying the accelerated aging periods (0, 24, 48, 72 and 96h) and seedling growth periods (48 and 72h), before submitting the seedlings to image analysis for seedling root length measurement. Considering the results obtained, the adaptation of accelerated aging test by reducing the aging duration from 96h to 48h, and the replacement of the germination test by seedling root length measurement using image analysis could be considered a potential tool for maize seed vigor assessment. The treatments composed of 48h of seed aging followed by seedlings root length measurements using image analysis provided reliable data, compared to traditional vigor tests and it could be considered an efficient and time-saving approach, associating two different concepts of seed vigor analysis.
