In order to determine the effects of water deficit stress, nitrogen fertilization and zeolite on chlorophyll fluorescence, pigments, trigonelline content and seed yield in, a split factorial experiment was laid out in a randomized complete block design with three replications. Five irrigation regimes were randomly applied to the main plots. Subplots included six treatments and consisted of a factorial combination of three nitrogen fertilization (untreated plots, vermicompost at a rate of 2.7 ton ha-1 and nitrogen chemical fertilizer at a rate of 11 kg.ha-1) and two zeolite rates (0 and 9 ton.ha-1). The results demonstrated that (Fm), (Fv), (Fv/Fm), chl a, b, total chl content and also seed yield were significantly reduced by water deficit stress, wheras minimum fluorescence (F0), carotenoid and trigonelline concentrations were increased. In addition, the highest Fv/Fm, chl a+b content and the lowest F0 and carotenoids were observed when irrigation was done after unloading 40% of ASW. In most treatments vermicompost increased the yield (by 25.51% and 98.32% in 2014 and 2015, respectively) and grain trigonelline concentration (7.46% in 2014) in Fenugreek. Mild water stress with vermicompost treatment is recommended for the production of trigoneline from Fenugreek seeds.

Malathion is one of the commonest type of organophosphate insecticide whose toxicity in human body is mainly considered to result from the induction of oxidative stress. The aim of this study was to investigate the antioxidant effect of Quercetin, a flavonoid compound, on the spatial memory and oxidative stress parameters during Malathion poisoning in male Wistar rats. This study was performed on nine groups, each of which consisted of eight male rats. Three days after intra-peritoneal injection of Quercetin, Malathion or a combination of these two drugs, the Moris Water-Maze apparatus was used to measure spatial memory parameters. The hippocampus was sampled and the oxidative stress parameters were measured in this area. Intra-peritoneal injection of Malathion (100 and 200 mg/kg) significantly reduced spatial memory parameters (P<0.01) and induced oxidative stress (P<0.001), whereas intra-peritoneal injection of quercetin (50 mg/kg) improved spatial memory in Malathion-poisoned experimental rats (P<0.05). Also, oxidative stress parameters in Malathion-treated groups showed a significant reduction in quercetin treatment (P<0.01). Quercetin was observed to restore the function of spatial memory and the level of oxidative stress parameters of the treated groups with Malathion to the normal level.
