The aim of this study was to evaluate effect of foliar application of titanium dioxide nanoparticles on quantitative traits and essential oil, thymol and carvacrol percent of thyme under different levels of water stress. Factorial experiment was used based on a completely randomized design with four replications. Factors included water stress (50, 70 and 90% of field capacity) and titanium diox...

Generally, narcissus is propagated through vegetative methods, but due to their low yield their are not economical. This study was conducted to develop a suitable method for the production of somatic embryos and bulblets in Narcissus papyraceus cv. Shirazi. Bulb scales were placed on the MS medium supplemented with 2,4-D and BAP each at 0.0, 0.25, 0.5 or 1 mg/l concentrations to form somatic em...

A biotechnological system for the production of plants biomass and phenylpropanoids maqui was developed in photomixotrophic TIBs. The vitro multiplication evaluated using combinations TDZ BAP TIBs 1L capacity. Treatment MS basal supplemented with 1 mg/L shows best results variables fresh weight rate. Photomixotrophic conditions were standardized media 3%, 2%, 1%, 0% sucrose at a light intensity...

It has been shown that L-arginine like the abused drugs could release dopamine from meso-cortico-limbic system. The purpose of the present study was to compare the effect of L-arginine with morphine as a standard abuse drug in the induction of conditioned place preference (CPP) in rat. For this purpose, male Wistar rats (250-300 g) were used in the experiments. Five days after surgical cannulat...

Micro-propagation of olive provides the possibility of producing clones of native plants with appropriate attributes and mass reproduction in short period of time, compared to conventional methods. Apical dominance in olive explants limits the growth of lateral branches in vitro. The effect of Woody Plant Medium (WPM), Olive Medium (OM) and Murashig and Skoog (MS) with carbohydrate source (mann...

The insecticidal toxicities of five essential oils against Pochazia shantungensis adults and nymphs, newly recorded pests, were evaluated. The LC50 values of Thymus vulgaris, Ruta graveolens, Citrus aurantium, Leptospermum petersonii and Achillea millefolium oils were recorded as 57.48, 84.44, 92.58, 113.26 and 125.78 mg/L, respectively, against P. shantungensis nymphs using the leaf dipping bi...

objective: n present study effect of various factors including sucrose, agar, peg, agno3, activated charcoal on somatic embryo induction and its subsequent regeneration was investigated using varieties dom siah and nemat. methods: 330 explant (mature embryos) of each varieties were cultured, 33/plate (100 x 15 mm), on callus induction murashige and skoog (ms) medium (murashige and skoog 1962) s...

The delayed effects of phencyclidine (PCP) have been shown to disrupt latent inhibition (LI) in a conditioned taste-aversion paradigm. In an attempt to understand the mechanism of this disruption, the delayed effects of the selective sigma receptor agonist 1,3-Di(2-tolyl)guanidine (DTG) and the selective NMDA receptor antagonist MK-801 on latent inhibition were assessed in the same paradigm. Wa...

The multiple shoots (14.2) from Oxalis corniculata differentiated through bud breaking on MS medium with 2.0 mg/l BAP. regenerated were further sub-cultured containing 1.0 BAP and 0.5 NAA. Vegetative to reproductive phase transition occurred in the cultures affected by plant growth regulators (PGRs), sucrose concentrations, strength of salts light. Flower buds initiated half Kn + NAA 3% sucrose...
