“…The studies on automated analysis of seedling images have basically compared results obtained from SVIS® with those from tests usually accepted for seed vigor evaluation, as observed with melon (Marcos-Filho et al, 2006), soybean , cucumber (Chiquito et al, 2012), sweet corn (Alvarenga et al, 2012), and wheat (Silva et al, 2012), among other crops.…”

The refinement of vigor tests and the possibility of utilizing computer resources for the effective evaluation of the seed physiological potential have attracted considerable interest from research and seed technologists. The aim of this study was to evaluate the physiological potential of maize seeds using the newly-created Automated Analysis of Seed Vigor System (Vigor-S) compared with other recommended seed vigor tests; two maize hybrids were used, each represented by seven seed lots. Germination and vigor (cold test, saturated salt accelerated aging, and field seedling emergence) evaluations were conducted. For the evaluation of seed vigor with the use of seedling image analysis resources, two systems were compared: the Seed Vigor Imaging System (SVIS ® ), developed by Ohio State University, USA and the Vigor-S, resulting from collaboration between USP/ESALQ and EMBRAPA (Embrapa Instrumentation). Using these two systems, three day old seedlings were scanned and the images were analyzed.Similar results for the vigor index, uniformity of development, and seedling length were obtained.The computerized image analysis of seedlings using Vigor-S has advantages with respect to accuracy, speed, and the possibility of automatic application to a worksheet. It is a consistent alternative for the evaluation of maize seed vigor, and produces information compatible with that obtained by the accelerated aging test and SVIS ® .

“…Recentemente, vários trabalhos de pesquisa indicam eficiência do uso de análise computadorizada de plântulas com o sistema SVIS ® na avaliação do vigor de sementes de berinjela (SILVA & CICERO, 2014), trigo (SILVA et al, 2012a), milho doce (ALVARENGA et al, 2012), crotalária (SILVA et al, 2012b), pepino (CHIQUITO et al, 2012), entre outras.…”

O trabalho teve como objetivo avaliar a eficiência do sistema computadorizado de análise de imagens de plântulas Seed Vigor Imaging System (SVIS(r)), em comparação com os outros testes recomendados para determinação do vigor de sementes de girassol. Foram utilizados dez lotes de sementes, cultivar Catissol 01, os quais foram avaliados quanto ao potencial fisiológico por meio dos testes de germinação, envelhecimento acelerado, emergência de plântulas em areia e em campo e análise de imagens de plântulas com o sistema SVIS(r), aos 0 e 4 meses de armazenamento. O delineamento experimental utilizado foi inteiramente casualizado para os testes realizados em laboratório e blocos ao acaso para o teste de emergência de plântulas em campo; em ambos os casos, foram utilizadas 4 repetições. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste de Scott Knott a 5% de probabilidade. Verificou-se que a análise computadorizada de imagens de plântulas com SVIS(r) é eficiente para avaliação do vigor de sementes de girassol.

“…Yet, under E2 environmental conditions, the index value for seed development uniformity of the lot 3 was already the lowest from the second storage month; whereas the seeds of lot 5 showed the highest uniformity index throughout the two and eight storage months. However, other studies on the use of the software SVIS ® to assess the seed physiological potential have shown that the development uniformity index was not sufficiently sensitive to allow distinction between different seed lots of soybean Santos et al, 2011), cucumber (Chiquito et al, 2012, and wheat (Silva et al, 2012a); but was efficient to assess vigor level of seeds of melon (Marcos-Filho et al, 2006) and sunn hemp (Silva et al, 2012b).…”

-This study aimed at evaluating efficiency of different tests to assess cotton seed vigor during storage, including the SVIS ® software. Thereby, five cotton seed lots (cv. BRS 293) were stored under controlled environmental conditions of low temperature and relative humidity (10 °C; 30% RH), and under non-controlled laboratory environmental conditions, for eight months. Evaluations of germination, first germination count, cool germination, accelerated aging test traditional and with saturated salt, field seedling emergence and seedling imaging automated analysis -SVIS ® were performed before and after every two storage months. It was concluded that the cool germination, accelerated aging (traditional and with saturated salt), field seedling emergence and seedlings length (SVIS ® ) are adequate parameters for assessing vigor of cotton seeds during storage, and that both accelerated aging and SVIS ® (vigor index and seedlings length) present enough sensitivity to identify changes on seed vigor during storage. . Cinco lotes de sementes de algodão (cv BRS 293) foram armazenados em câmara fria e seca (10 °C e 30% UR do ar) e em ambiente natural, durante oito meses. As avaliações da germinação e do vigor (primeira contagem de germinação, germinação a baixa temperatura, envelhecimento acelerado tradicional e com solução saturada de NaCl, emergência de plântulas em campo e análise computadorizada de imagens de plântulas -SVIS ® ) foram realizadas no início e a cada dois meses de armazenamento. Concluiu-se que os testes de germinação a baixa temperatura, envelhecimento acelerado (tradicional e com solução saturada de NaCl), emergência de plântulas em campo e SVIS ® (comprimento de plântulas) são adequados para avaliação do vigor de sementes de algodão durante o armazenamento. Além disso, os testes de envelhecimento acelerado (tradicional e com solução saturada de NaCl) e as análises SVIS ® (índice de vigor e comprimento de plântulas) apresentam sensibilidade na identificação da queda do vigor das sementes durante o armazenamento.Termos para indexação: Gossypium hirsutum L., potencial fisiológico, armazenamento.1
