“…Replacing pure water with a saturated salt solution means that seeds absorb less water, which slows ageing process (Jianhua and McDonald, 1997). The test has been widely studied and found efficient for brassicas (Costa et al, 2008), melon (Torres and MarcosFilho, 2003), arugula (Ramos et al, 2004), pumpkin and zucchini (Dutra and Vieira, 2006), and beetroot (Silva et al, 2006). Although studies on the SSAA test are relatively numerous, some factors affecting the precision of results such as temperature and seed ageing duration must still be determined for several species, and methods should be standardized.…”

Adequate seed vigour tests are fundamental in evaluating vigour level and consequent performance of seed lots in storage and in the field conditions. The accelerated ageing is one of the most important of these tests. To establish the best accelerated ageing procedure for evaluating the vigour of crambe seeds, we compared results from the traditional method (ageing periods of 24, 48, and 72 hours at temperatures of 41 and 45 °C) and the saturated salt accelerated ageing (SSAA) (NaCl) method. In addition to accelerated ageing, germination in a sand substrate, seedling emergence in laboratory, and seed moisture content before and after seed ageing were determined. Our first count was highly sensitive in detecting seed vigour level. Both the traditional and SSAA methods can be used to efficiently classify the vigour of crambe seed lots and could be promising techniques for crambe seed quality control programs. To evaluate vigour of crambe seed lots, the traditional accelerated ageing test should be executed for 48 hours at 41 °C and the SSAA method, for 24 hours at 41 or 45 °C. Seedling assessment should be carried out on the fourth day for both methodologies.

“…CDT treatment with 24% SMC, 45 °C, for 24 hours is the best method to estimate the physiological quality of onion seeds (Rodo & Filho, 2003) and beetroot (Silva et al, 2006)seeking to associate these results with seedling emergence in the field. Consequently, five seed lots of Top Tall Early Wonder cultivar were submitted to the tests of germination, seedling emergence in the field, accelerated ageing (using periods of 24, 48 and 72 hours at 42\u00b0C.…”

Deterioration of seeds during storage may reduce the supply of high-quality seeds which become the limiting ‎factor of soybean production in tropical countries. Controlled Deterioration Test (CDT) is one of the ‎fastest vigor testing methods. The objective of this study was to achieve the suitable moisture content and ‎duration of CDT treatment in soybean seed, then establish a model that associated with the seed vigor in ‎the field after a certain time of storage. Split-plot with 2 factors, namely seed varieties and the combination of ‎moisture content and heat exposure duration were used to determine the influence of CDT treatment. ‎Another split-plot for 2 factors, namely storage period and seed varieties were used to determine the effect ‎of shelf life. Viability parameters were observed by germination strength (GS) and seedling vigor index (VI), ‎using a rolled paper towel method. The results showed that there was an interaction between soybean seed ‎varieties and the combination of seed moisture content treatment with duration of CDT exposure. Sindoro ‎and Tanggamus varieties had higher viability and storability than other varieties. Combinations of 28% seed ‎moisture content for 24 hours CDT duration were sensitive enough to evaluate the physiological potential of ‎soybean seeds, providing information that was closely related to seed germination after stored for 1 month. ‎

Entretanto, Silva et al (2006), estudando o teste de DC em sementes de cinco lotes da mesma espécie e cultivar utilizadas no presente trabalho, submetidas a 41 e 45 o C, com teores de água de 22, 24 e 26%, durante 12, 24 e 36 horas, verificaram que a melhor combinação para classificação dos lotes em níveis de vigor foi a de 45 o C/24%/24 h. Os resultados evidenciaram que os diferentes procedimentos para a condução do teste de DC foram suficientes para deteriorar as sementes. A queda no desempenho germinativo ocorre porque a exposição de sementes a altas temperatura e umidade relativa do ar provoca alterações que influenciam a síntese de proteínas, de ácidos nucléicos e o metabolismo do DNA (Vásquez et al, 1991).…”

RESUMO -O uso de testes de vigor é fundamental na avaliação do potencial fisiológico de sementes produzidas e comercializadas. O trabalho foi realizado com o objetivo de estudar o uso do teste de deterioração controlada na avaliação do potencial fisiológico de sementes de beterraba. Após lavagem dos frutos contendo as sementes em água corrente, oito lotes da cultivar Top Tall Early Wonder foram previamente avaliados pelos testes de germinação e de emergência de plântulas (EP). Para o ajuste do teor de água (TA) foram estudados os métodos de atmosfera úmida (AU) e substrato úmido (SU). O teste de deterioração controlada (DC) foi conduzido com 22 e 24% de água e exposição durante 12, 24 e 36 horas à temperatura de 45 ºC. Usou-se o delineamento experimental inteiramente casualizado, com oito repetições de 25 sementes, exceto o de EP, conduzido com quatro repetições de 50 sementes. Os dados foram analisados separadamente para cada combinação TA x períodos de deterioração e as médias comparadas usando-se o teste de Tukey (P≤0,05). Análises de correlação simples foram estabelecidas entre os resultados dos testes de laboratório e a EP. O ajuste do TA de semente deve ser feito pelo método do SU. O teste de DC pode ser utilizado para avaliar o potencial fisiológico de sementes de beterraba, sendo indicada a combinação TA de 22%, a 45 o C, durante 24 horas.Termos para indexação: Beta vulgaris, germinação, vigor, emergência de plântulas. CONTROLLED DETERIORATION OF BEETROOT SEEDSABSTRACT: The vigor test is a fundamental test used to evaluate the physiological potential of produced and commercialized seeds. Controlled deterioration was studied as a method to evaluate the physiological potential of beetroot seeds (Beta vulgaris). After immersing the fruits in running water, eight seed lots of cultivar Top Tall Early Wonder were evaluated as to germination and seedling emergence. The seed water content (SWC) was adjusted using the wet atmosphere and moist substrate methods. The controlled deterioration test was a completely randomized design with eight replicates of 25 seeds and was conducted at 45 o C using a SWC of 22% or 24% and deterioration times of 12, 24 and 36 hours. The experimental design for seedling emergence tests was also completely randomized but used four replicates of 50 seeds. The data were statistically analyzed for each combination of SWC and deterioration period separately and the means compared by the Tukey test (p≤0.05). Simple correlation analysis was run using the data from seed laboratory tests and seedling emergence. The results indicate that SWC adjustment should be carried out only using the moist substrate method. Physiological potential of beetroot seeds can be evaluated using the controlled deterioration test with parameters of 45 o C, 24 hours and 22% SWC.
