“…These results disagree with the ones obtained by Costa et al (2008), when testing pea seeds submitted to pre-hydration, it was possible to distinguish inferior lots using this parameter. Nevertheless, Vanzolini and Nakagawa (2003), analyzing the same test for peanut seeds were not able to distinguish amounts of Mg 2+ of their lots, while Costa et al (2007), studying the relationship between magnesium and physiological potential in onion seeds, noticed a downfall of this parameter during their work.…”

“…According to Costa et al (2008), calcium atomic radius is bigger than potassium and magnesium; this characteristic may have hampered calcium transposition through the membranes, in such way that they couldn't detect the presence of Ca in their trial using pea.…”

“…Vigorous seeds present a greater repairing capacity of damages in cell membranes. Therefore, during soaking, the electrolytic leaching is smaller (MARCOS FILHO, 2005;BINOTTI et al, 2008;COSTA et al, 2008).…”

“…High concentrations -of the above substances -can be an indicative of vigor and germination loss (MARCOS FILHO, 2005;BINOTTI et al, 2008). Among the best studied electrolytes, to try establishing a correlation with physiological quality of seeds, are calcium, magnesium and potassium, which are researched by many authors (BINOTTI et al, 2008;COSTA et al, 2008;FESSEL et al, 2010;SILVA et al, 2012).…”

ABSTRACT:The development of researches about vigor provides greater insight about the physiological behavior of seeds over storage periods. The aim of this study was to evaluate the biochemical changes which occurred in beans stored for 360 days. Analyses were performed at 0, 30, 90, 180, 270, and 360 days after receiving the seeds (S1 and S2) and grains (G1 and G2) of BRS Splendor. The following tests were conducted: water content, electrical conductivity, and chemical composition of the soaking solution, where sugars and ions Fe 2+ , Zn, Ca 2+ , Mg 2+ and K + were quantified. The experimental design was completely randomized split-plot and means were compared through Tukey test (p>0.05). Water content decreased after 90 days, and after 180 days reached an average of 16%. The electrical conductivity showed the greatest loss of solute after 90 days. Larger amounts of soluble sugars were found in S1 and G1. The quantities of potassium and calcium decreased after 360 days, while magnesium increased after 90 days of storage. The electrical conductivity test showed no direct relation to the quantification of the investigated ions. The amount and behavior of amino acids and studied ions did not showed relation to the decrease in vigor of beans.

This study aimed to investigate the relationship between the hydration pattern of landrace bean genotypes and their physiological quality. The hydration curve of eight landrace (BAFs 07, 13, 23, 42, 44, 50, 55, 81) and two commercial cultivars (IPR-88-Uirapurú and Iapar 81) genotypes was determined from seed moisture. Determination of initial physiological quality was performed by germination and vigor tests (seedling performance and accelerated aging). Characterization of the genotypes, regarding accelerated aging tests, showed that BAFs 13, 42, 55 and 81 had the highest physiological potential, whereas BAFs 07, 23, 44, 50 and the commercial cultivars had lower physiological quality. The hydration curve followed a triphasic pattern with radicle protrusion occurring between 21 and 27 hours after seed hydration. The percentage of reserves translocated to the seedling during formation showed that BAF 42 had the highest conversion efficiency compared to the smaller efficiencies of BAFs 23, 50 and Iapar 81. The seedling length test showed that BAFs 42 and 55 had the most vigorous seedlings, which was driven by the high percentage of reserves translocated to the seedling during formation. BAFs 23, 50 and the cultivar Iapar 81 showed lower reserve translocation, demonstrating that low mobilization potential leads to smaller seedlings. The hydration of bean seeds during germination was affected by physiological quality, as genotypes considered more vigorous exhibited higher hydration rates than those of the less vigorous genotypes.

ResumoO trabalho objetivou verificar relação do padrão de hidratação de genótipos crioulos de feijão e a sua qualidade fisiológica. Utilizaram-se oito genótipos crioulos (BAFs 07, 13, 23, 42, 44, 50, 55, 81) e dois comerciais (IPR-88-Uirapurú e Iapar 81) submetidos à determinação da curva de hidratação por meio da umidade das sementes. A determinação da qualidade fisiológica inicial foi realizada por meio do teste de germinação e testes de vigor (desempenho de plântulas e envelhecimento acelerado). A caracterização dos genótipos quanto ao teste de envelhecimento acelerado evidenciou os BAFs 13, 42, 55 e 81 como sendo de maior potencial fisiológico, e os BAFs 07, 23, 44 e 50 e cultivares comerciais, apresentando menor qualidade fisiológica. A curva de hidratação seguiu padrão trifásico com protrusão radicular entre 21 e 27 horas. O percentual de reserva translocada para a formação da plântula demonstrou que o BAF 42 obteve a maior eficiência de conversão comparada às menores, BAFs 23 e 50 e cultivar Iapar 81. Os BAFs 42 e 55 apresentaram plântula mais vigorosa pelo teste de comprimento de plântulas, decorrente do alto percentual de reserva translocada para a formação da plântula. Os BAFs 23 e 50 e a cultivar Iapar 81 apresentaram menor translocação de reservas e demonstraram que este baixo potencial de mobilização culminou com plântulas menores. A hidratação das sementes de feijão durante a germinação foi afetad...
