some possible effects of exogenous application of salicylic acid (sa) and bacillus subtilis on infection potential of root and stem rot disease and on induction of resistance against this pathogen were investigated in laboratory and as well under greenhouse conditions. in vitro, the effectiveness of sa concentrations (2-8mm) on growth of b. subtilis was observed as negative, while sa applicatio...

compound of 5-aminolevulinic acid (5-ala) has herbicide behavior in high concentration. while, it acts as growth regulator at low concentrations and causes resistance to various stresses incluing cold and salibity. therefore the exogenous application of 5-aminolevulinic acid was investigated to induce cold stress tolerance in young soybean plants (glycine max l.). the experiment was conducted a...

To find the protective role of exogenous nitric oxide (NO) on salinity-stressed rice seedlings, a CRD-based factorial experiment with three replications was conducted in Agronomy Laboratory of the Faculty of Agricultural Sciences, University of Guilan, in 2012. The experimental design consisted of healthy and vigorous seedlings of two rice cultivars, Khazar and Goohar, the last already known as...

In lizards as in many other kinds of animals, strong maternal effects on the phenotypic traits of hatchlings are frequently reported. One plausible non-genetic mechanism that might produce such differences among clutches involves maternal allocation of steroid hormones. Lizard eggs often display considerable inter-clutch variation in the quantities of maternally allocated steroids, and exogenou...

Abstract: In order that the nth-order Generalized Frequency Response Function (GFRF) for nonlinear systems described by a NARX model can be directly written into a more straightforward and meaningful form in terms of the first order GFRF and model parameters, the nth-order GFRF is now determined by a new mapping function based on a parametric characteristic. This can explicitly unveil the linea...

In practice, it is usually difficult to obtain the physical model of nonlinear, rotor-bearing systems due to uncertain nonlinearities. In order to solve this issue to conduct the analysis and design of nonlinear, rotor-bearing systems, in this study, a data driven NARX (Nonlinear Auto-Regressive with exogenous inputs) model is identified. Due to the lack of the random input signal which is requ...

a 2 × 3 factorial experiment was conducted to investigate the effect of enzyme endofeed w (eew) at 0 and 0.05%, thyme essential oil (teo), probiotic primalac® (pp) and non-feed additive, on intestinal histomorphology of broilers fed wheat-based diet. each of the 6 dietary treatments was replicated 4 times with 12 chicks each from 0 to 42 days of age. there was no interaction between enzyme and ...

The influence of exogenous application of glycine betaine (GlyBet) was examined on photosynthetic pigments and ions concentration of safflower under salinity stress conditions. The experiment was performed in a randomized complete block design arranged as a factorial with three replications. Salinity treatments (0, 50, 100, and 150 mM) were applied using sodium chloride (NaCl). GlyBet (0, 10, 3...
