“…Research has shown that seed quality is influenced by genotype, environment during seed development, and seed storage conditions (Clerkx et al, 2004;Fessel et al, 2006;Açıkgöz et al, 2013;Hampton et al, 2013;Hay et al, 2013;Uddin et al, 2013). Our results suggest significant differences in longevity could not be found between either different species of the same genus (Diplotaxis tenuifolia and D. erucoides), or different seed lots of the same species (D. tenuifolia).…”

The aim of this study was to determine whether the loss of germinability and vigour in wall-rocket seed lots was related to electrolyte leakage. Ten seed lots of 2 wall-rocket species (9 of Diplotaxis tenuifolia and one of D. erucoides (Brassicaceae)) were stored at 45 °C and 70% relative humidity and electrolyte leakage was measured using the conductivity test. Small differences in longevity were found among species or seed lots, suggesting that a similar relative longevity might be expected within the genus Diplotaxis after artificial ageing, and that it will be above the average of that found in other species of the same family at similar storage conditions. Electrolyte loss was strongly related to loss of seed viability. There was a negative linear relationship between conductivity and seed germination (R 2 = 0.85), and a positive relationship with T 50 (R 2 = 0.77). Small differences were found among species or seed lots regarding the correlation between electrolyte leakage and seed germination and vigour. Our results indicate that the conductivity method is able to predict the viability of wall-rocket seeds stored at 45 °C and 70% RH, with the same regression equation of conductivity and germination (-33.97x + 135.59) being able to predict the viability of different seed lots and species. A conductivity level ranging from 1.4 to 2.2 mS g -1 DW would indicate that the potential of a Diplotaxis seed lot to germinate has decreased to 80%. The correlation between electrolyte leakage and seed germination provides a valuable means for early detection of seed viability in wall-rocket seeds.

“…Similar results were found by the present study, which wasn't able to use this variable (Ca) when analyzing seeds vigor. Whereas calcium increase was documented by Fessel et al (2006) for corn, by Fessel et al (2010) for soy seeds with high and low vigor, and by Silva et al (2012) in lots of beans with lower physiological quality.…”

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.

“…Studies with peanut (Arachis hypogaea L.) (Vanzolini and Nakagawa, 1999b), soybean (Glycine max (L.) Merrill) (Vieira et al, 2002), corn (Zea mays L.) (Fessel et al, 2006) and cowpea (Vigna unguiculata (L.) Walp.) seeds have shown that the electrical conductivity test is suitable for evaluating a seed lot's vigour.…”
