“…Accelerated ageing of most crop seeds, which consists of seed storage under conditions of high humidity and temperature, causes severe damage and a loss of vigor in the seeds. This is associated with a progressive decrease in seed germination (Sveinsdóttir et al, 2009). Accelerated ageing was developed as a test method to estimate the longevity of seeds under a range of storage conditions (Ravikumar et al, 2002).…”

“…The seed during the latency state can be considered a living organism that neither produces nor consumes biomass. Recent papers relate the germination process to the availability of enzymes such as H + -ATPasa (Sveinsdóttir et al, 2009) which increases in concentration as germination begins. During the seed latency state it is believed that there are low concentrations of ATP as well as other enzymes that promote active transport through the cell membrane.…”

A b s t r a c t. The plant seed embryo tissue cell, including the cell membrane and the intracellular and extracellular regions, was modelled as a spherical body. Equations for the three components in spherical coordinates were developed to calculate potassium ions flux in the presence of a stationary magnetic field. Simultaneous mathematical simulations of radial flux for potassium, calcium and chloride ions as well as membrane potential and osmotic pressure were calculated. Results obtained by computerized simulation showed that a magnetic field of 200 mT provoked some changes in cellular ionic concentration with respect to exposure time during first 30 s, which also impacted on the membrane potential and osmotic pressure values.K e y w o r d s: magnetic field, ions, membrane, model, seed INTRODUCTIONThe effects of magnetic field on post-germination processes in seeds have been studied for some time (Aladjadjiyan, 2007;Flórez et al, 2007;Pietruszewski et al., 2007). The principal results show that some values of magnetic induction and exposure time provoke increments in germination percent, root and stem length as well as the biomass, at second week after sowing (Galland and Pazur, 2005). These effects are still waiting for clarification from the theoretical point of view because they involve numerous factors that affect germination and plant development. Modification in chlorophyll content (Taia et al., 2007), peroxidase content (Atak et al., 2007), increased water adsorption (Socorro and Fraga, 2007), rate growth increments at later stages of the vegetative cycle (De Souza et al., 2006) and increased yield (Rochalska et al., 2009) have been found experimentally. Nevertheless, exposures of different species to equal magnetic fields do not provide the same experimental results (Pietruszewski et al., 2007). Several announcements (with commercial purposes) have erroneously proposed that exposure of any biological organism to magnetic field of any strength always provides benefits to the organism (González, 2003). Although magnetic induction values below 400 mT do not provoke damage to DNA (Suzuki et al., 2001), such exposure may or may not benefit living organisms: the type of magnetic field and its intensity must be taken into account. For example, stationary and variable magnetic field effects are not equal, while quantifiable values of magnetic field induction on biological tissue are relatively very low (near the nanoTesla level). On the other hand, magnetic induction values between 10 and 200 mT can interact with the flux of charged particles through the cell membrane and modify their corresponding concentrations. This in turn may affect the osmotic mechanism governing water flux (osmoregulation) . Increases in the cytokine and auxin synthesis have been suggested to explain lengthening of plant organs after exposure to magnetic fields (Atak et al., 2003). The theory which underlies the interaction between the seed (specifically the tissues that comprise it) and a stationary magnetic field is very complex. A...

“…En Brassica napus, el osmoacondicionamiento afectó 952 genes y 75 proteínas; además, la inmersión, el secado y la germinación encienden vías específicas, con un número limitado de genes y proteínas involucrados en todas las fases, la gran mayoría tiene participación en una sola de las vías (Kubala et al, 2015). Parte importante en el proceso de la germinación lo tiene la H + ATPasa, que provee la fuerza de empuje para la entrada y salida de iones y metabolitos a través de la membrana plasmática y está activa a las dos horas después de la imbibición (Mei y Song, 2008;Sveinsdottir et al, 2009).La inmersión previa de la semilla en soluciones osmóticas, incluso en agua, puede mejorar el comportamiento de la semilla durante la germinación. Diversos resultados muestran que las semillas osmoacondicionadas mejoran su tasa de germinación, así como el comportamiento de la plántula, among the studied races; a finer fractionation is desirable in extracting proteins and more sensitive techniques for the detection of differences.…”

ResumenEn la presente investigación se osmoacondicionaron semillas de dos razas de maíz, con PEG o con nitrato de potasio más ácido giberélico, para estimar su efecto en las variables: germinación, peso y longitud de radícula y plántula, acidez titulable y patrón electroforético de proteínas; se les sometió a remojo (hipoxia, "soak test") y se cuantifico la respuesta. El objetivo fue contribuir a la caracterización de los maíces nativos de México que se siembran bajo condiciones de temporal. Los maíces Bofo y Elotes Occidentales mostraron la mayor imbibición con KNO3 + ácido giberélico durante 12 h. El porcentaje de germinación después del remojo, fue mayor con KNO3 + ácido giberélico durante 6 h y fue superior al testigo. En cuanto a la longitud de radícula y plúmula, los tratamientos superaron al testigo, en ambos conteos. Con Elotes Occidentales, luego de la prueba de remojo, los tratamientos resultaron superiores al testigo en longitud de plúmula. La semilla osmoacondicionada tuvo una tendencia a presentar mayor longitud de plúmula y radícula y mayor porcentaje de germinación cuando la semilla se sometió posteriormente a remojo. Los patrones electroforéticos son muy semejantes, lo que indica gran parecido a nivel bioquímico entre las AbstractIn this research, seeds of two maize races, with PEG or potassium nitrate plus gibberellic acid, were osmoconditioned to estimate its effect on the variables: germination, weight and length of radicle and seedling, titratable acidity and electrophoretic pattern of proteins; they were soaked (hypoxia, "soak test") and the response was quantified. The objective was to contribute to the characterization of the native maize of México that are sown under rainfed conditions. The Bofo and Elotes Occidentales maize showed the highest imbibition with KNO3 + gibberellic acid for 12 h. The germination percentage after soaking was higher with KNO3 + gibberellic acid for 6 h and was superior to the control. As for the length of radicle and plumule, the treatments exceeded the control in both counts. With Elotes Occidentales, after the soaking test, the treatments were superior to the control in plumule length. The osmoconditioned seed showed a tendency to have a longer plumule and radicle length and a higher percentage of germination when the seed was subsequently subjected to soaking. The electrophoretic patterns are very similar, indicating a great similarity at the biochemical level IntroducciónEl osmoacondicionamiento consiste en la imbibición controlada de la semilla en soluciones osmóticas o agua, interrumpiéndose dicho proceso antes de la protrusión de la radícula. Las semillas tratadas incrementan su porcentaje de germinación, así como el crecimiento de las plántulas, mejorando la calidad nutrimental de los cultivos como el maíz. Con la imbibición de la semilla y la activación de enzimas debida al efecto de las giberelinas, se activan glucanasas que degradan el endospermo almidonoso, cuyos productos son absorbidos por el escutelo (Preston et al., 2009). Durante la germinació...
