“…Accordingly, seeds that present a higher expression of such enzyme have a better physiological quality, as proven by the physiological tests in this study and also confirmed by Carvalho et al (2014a). Carvalho et al (2014c) also observed a higher alcohol dehydrogenase expression in seeds that presented a better physiological quality.…”

Harvest delay may affect the physiological quality of soybean seeds due to the occurrence of unfavorable environmental conditions in the field. This study was conducted to investigate the physiological and enzymatic changes in soybean seeds submitted to harvest delay. A randomized block design, with eight seed harvest periods (0; 5; 10; 15; 20; 25; 30; and 35 days after the R8 phenological stage - full maturity) of the BRS 820 RR® cultivar, with four replicates, was used. At each harvest period, the moisture content, 1,000-seed weight, germination, seedling emergence, emergence speed index, accelerated aging, vigor and viability (tetrazolium test), electrical conductivity, enzymatic expression and seed yield were measured. Harvest delay up to 35 days after the R8 phenological stage do not affect the 1,000-seed weight and seed yield. The delayed harvest from the R8 stage results in increased damage by stink bugs and moisture. The harvest delay of seeds from the 10th day after the R8 stage impairs the seed vigor and, from the 15th day, seed germination. Seeds harvested with a delay after the R8 stage have lower expressions of the following isoenzymatic systems: malate dehydrogenase, alcohol dehydrogenase, esterase, isocitrate lyase and superoxide dismutase, especially after 15 days of harvest delay.

“…The seed vigor characteristics decreased after a delay of 10 days and germination especially after 15 days (Figures 2 and 3). Esterase is linked to lipid degradation, an important process for soybean seed germination (Carvalho et al 2014c). The greatest increase in the esterase enzyme expression may be related to greater germination values.…”

Resumo -O objetivo deste trabalho foi determinar alterações fisiológicas e isoenzimáticas em sementes de genótipos de soja, em diferentes condições de armazenamento. Utilizou-se o delineamento experimental inteiramente casualizado com quatro repetições, em arranjo fatorial com seis cultivares de soja (TMG 1176, TMG 1179 e GB 874) e cinco periodos de armazenamento (0, 2, 4, 6 e 8 meses), em dois ambientes de armazenamento (câmara fria e seca, a 10ºC e 50% de umidade relativa; e armazém convencional, em condições não controladas). A qualidade fisiológica foi avaliada por meio de testes de germinação, de envelhecimento acelerado e de frio. As expressões isoenzimáticas determinadas foram as de malato desidrogenase (MDH), álcool desidrogenase (ADH), esterase (EST), isocitrato liase (ICL), superóxido dismutase (SOD) e peroxidase (PO). Sementes de soja armazenadas em câmara fria e seca conservaram sua qualidade fisiológica. Após seis meses de armazenamento, em condições não controladas, a qualidade das sementes e as atividades isoenzimáticas de MDH, ADH, EST, ICL, SOD e PO diminuíram. No armazenamento em câmara fria e seca, não ocorreu alteração nas sementes. Os genótipos de soja apresentam diferentes níveis de tolerância ao armazenamento e expressões isoenzimáticas.Termos para indexação: Glycine max, câmara fria, enzimas, potencial de armazenamento. Isozyme alterations in soybean cultivar seeds at different storage conditionsAbstract -The objective of this work was to determine the physiological and isozyme alterations in seeds of soybean genotypes, under different storage conditions. A completely randomized experimental design was used with four replicates, in a factorial arrangement with six soybean cultivars (TMG 1176, TMG 1179, TMG 132, TMG 133, TMG 115, and GB 874) and five storage times (0, 2, 4, 6, and 8 months), in two storage environments (a cold and dry chamber, at 10ºC and 50% relative humidity; and a conventional warehouse, under uncontrolled conditions). Physiological quality was evaluated by the germination, accelerated aging, and cold tests. Isozyme expressions of malate dehydrogenase (MDH), alcohol dehydrogenase (ADH), esterase (EST), isocitrate lyase (ICL), superoxide dismutase (SOD), and peroxidase (PO) were determined. Soybean seeds stored in cold and dry chambers maintained their physiological quality. After six months storage under uncontrolled conditions, seed quality and isozyme expressions of MDH, ADH, EST, ICL, SOD, and PO lowered. There was no alteration on seed stored in cold and dry chambers. Soybean genotypes show different tolerance levels to storage and isozyme expression.Index terms: Glycine max, cold chamber, enzymes, storability. IntroduçãoPara a obtenção de produtividade satisfatória da soja, é necessária a utilização de sementes com elevada qualidade, entre outros fatores. Scheeren et al. (2010) verificaram que a produtividade resultante de lotes de sementes com alto vigor, pode ser 9% superior à de sementes com baixo vigor.No período pós-colheita, as sementes necessitam de armaz...

“…Thus, the seeds become less susceptible to the deleterious action of acetaldehyde with the higher ADH activity (Zhang et al, 1994). Carvalho et al (2014b) observed greater ADH expressions on seeds from soy cultivars that showed greater physiological quality, which may be related to the maintenance of the germination metabolism of the seeds from the Everglades cultivar stored at high temperatures (35 o C) for 120 days (Table 2). …”

-The objective of the study was to determine the physiological and isozyme alterations in lettuce seeds submitted to different conditions and storage periods. We used a completely randomized design with four replications in a factorial arrangement with six lettuce cultivars (Everglades, Babá de Verão, Elisa, Grand Rapids, Hortência and Salinas 88) and four storage periods (30, 60, 90 and 120 days), on three storage rooms (15, 25 and 35 ° C). The physiological quality was evaluated by first and final germination count, emergence, and germination and emergence speed indexes. The isoenzyme expression of catalase (CAT), esterase (EST), alcohol dehydrogenase (ADH) and malate dehydrogenase (MDH) were determined. The physiological quality of lettuce seeds was preserved when stored at 15 ° C room temperature. The high room temperatures associated with higher storage periods cause a reduction in physiological quality and alterations in enzymatic patterns of CAT, EST, ADH and MDH. For seeds stored at 15 ° C, there were no physiological changes. The lettuce cultivars, especially Everglades, have different levels of tolerance to storage and isoenzyme expressions.Index terms: Lactuca sativa, enzymes, storability, thermotolerance.Alterações fisiológicas e isoenzimáticas em sementes de alface em diferentes condições e períodos de armazenamento Termos para indexação: Lactuca sativa, enzimas, potencial de armazenamento, termotolerância.
