The experiment was conducted in order to study effects of seeds priming with gibberellic acid (GA3) at 0, 3, 5 and 8 mM on germination, growth and antioxidant enzymes activity in alfalfa seedlings under salinity stress (200 mM NaCl). All control seeds germinated. The rate of germinated seeds was reduced to 48% in the presence of NaCl, and increased to 76% after seeds priming with 5 mM GA3. Priming with 5 mM GA3 was also correlated with an increase of dry weight of seedlings derived from both stressed and non-stressed seeds as well as with the reduction of electrolyte leakage (EL) and malondialdehyde (MDA) level in salt stressed seedlings. The activity of superoxide dismutase, catalase, guaiacol peroxidase and ascorbate peroxidase in primed and non-primed seeds increased in the presence of NaCl and after priming of seeds with 5 mM GA3, whereas only small effect on glutathione reductase activity in both primed and non-primed seeds was observed. The total ascorbate level was higher in both stressed and non-stressed seedlings from primed seeds. These results suggest that GA3 priming might increase the salt tolerance of alfalfa seedlings through enhancing the activities of antioxidant enzymes and reducing the membrane damage as estimated using biomarkers, EL index and MDA content.

2017. Quantifying allelopathic effect of rapeseed on germination and seedling growth of maize under different salinity levels. Zemdirbyste-Agriculture, 104 (3): 259-266 AbstractBrassica species have been reported as having allelopathic effect, reducing seed germination and emergence of subsequent cereal crops when grown in a rotation. Therefore, laboratory and greenhouse experiments were conducted to determine the allelopathic potential of rapeseed (Brassica napus L.) on germination and seedling growth of maize (Zea mays L.) under different salinity levels. Laboratory experiment consisted of two factors including different plant parts (root, shoot, leaf and whole plant) and their various concentrations (0, 5, 10, 15 and 20 %). In a greenhouse experiment three factors were studied including different salinity levels (0, 4 and 8 %), crop residue concentrations (0, 2 and 4 %) and decomposition time (2 and 4 weeks). The experiment was laid out in a completely randomized design with factorial arrangement where treatments were repeated five times for germination experiment conducted in Petri plates and three times for soil bioassay experiment conducted in pots. The results showed that extracts of different plant parts could not affect the germination, while different concentrations showed significant effect on maize seed germination. The interaction of extracts of different plant parts with different concentrations significantly affected the growth. Root and leaf extracts at 5% concentration produced maximum root length, shoot length and plant dry weight as compared to other plant parts at other concentrations. For the second experiment or greenhouse experiment the results showed that neither plant parts nor decomposition period could influence germination significantly. However, salinity levels showed inhibitory effect on germination with increase in salt concentration. The rapeseed residue concentration of 2% with 4% salt concentration produced maximum plant fresh and dry weight. Rapeseed showed allelopathic potential on germination and seedling growth of maize, but this influence was decreased gradually with the increase of salinity.

“…For each reaction, SParSE++ then chooses the interpolant with the highest R 2 statistic. R 2 statistics are commonly used to assess goodness of fit of statistical models to observed data [22]. For our purposes, the R 2 value, which is between 0 and 1, indicates the fraction of the total variance of output () that is explained by variation in input ( γ ).…”

BackgroundDespite the increasing availability of high performance computing capabilities, analysis and characterization of stochastic biochemical systems remain a computational challenge. To address this challenge, the Stochastic Parameter Search for Events (SParSE) was developed to automatically identify reaction rates that yield a probabilistic user-specified event. SParSE consists of three main components: the multi-level cross-entropy method, which identifies biasing parameters to push the system toward the event of interest, the related inverse biasing method, and an optional interpolation of identified parameters. While effective for many examples, SParSE depends on the existence of a sufficient amount of intrinsic stochasticity in the system of interest. In the absence of this stochasticity, SParSE can either converge slowly or not at all.ResultsWe have developed SParSE++, a substantially improved algorithm for characterizing target events in terms of system parameters. SParSE++ makes use of a series of novel parameter leaping methods that accelerate the convergence rate to the target event, particularly in low stochasticity cases. In addition, the interpolation stage is modified to compute multiple interpolants and to choose the optimal one in a statistically rigorous manner. We demonstrate the performance of SParSE++ on four example systems: a birth-death process, a reversible isomerization model, SIRS disease dynamics, and a yeast polarization model. In all four cases, SParSE++ shows significantly improved computational efficiency over SParSE, with the largest improvements resulting from analyses with the strictest error tolerances.ConclusionsAs researchers continue to model realistic biochemical systems, the need for efficient methods to characterize target events will grow. The algorithmic advancements provided by SParSE++ fulfill this need, enabling characterization of computationally intensive biochemical events that are currently resistant to analysis.Electronic supplementary materialThe online version of this article (doi:10.1186/s12918-016-0367-z) contains supplementary material, which is available to authorized users.
