  To evaluate the effects of spraying potassium nano-particles on the osmolytes, photosynthetic pigments, total carotenoids and nutrients of aerial parts of common glasswort (Salicornia europaea L.), a factorial experiment based on randomized complete block design with three replications was conducted at the marginal lands of Lake Urmia in 2012. The treatments consisted of application of potassium nano-particle concentrations at five levels (0, 1, 2, 3 and 4 g/l of K nano-particles) applied, once, twice and three times. Results of analysis of variance (ANOVA) showed that there were significant interaction between the levels and concentrations of potassium nano-particles sprayings on aerial parts with respect to their contents proline, total soluble carbohydrates, total chlorophyll, chlorophyll a and b, total carotenoids (xanthophyll and carotene) and nutrients (nitrogen, phosphorus, potassium, calcium and sodium). The highest levels of proline (1.84 mg/g dry weight) at one time spraying 4 g/l of K, total soluble carbohydrates (66.9 mg/g dry weight) at three times spraying 4 g/l, total chlorophyll (26.23 mg/g fresh weight) and chlorophyll b (22.85 mg/g fresh weight) at two times of water spraying, and chlorophyll a (9.93 mg/g fresh weight) at three times of 4g/l of potassium nano-particles sprayings were obtained. The highest nitrogen (0.95 % of aerial parts) and phosphorus (2.99 g/kg dry weight of aerial parts) contents were obtained from three times water spraying. However, the highest amounts of aerial plant part of potassium (65.08 g/kg dry weight) and sodium (403 g/kg dry weight) belonged to the two times, and calcium (29.23 g/kg dry weight) to the three times spraying of 4 g/l nano-potassium. Despite of the high concentration of osmolytes by potassium spraying, the nutrient accumulations levels were not significantly different from each other. Manuscript profile

  This experiment was carried out to analyze some primary and secondary compounds in various organs of Lactuca serriola during phenological vegetative growth stage. After collecting aerial parts of L. Serriola from the farms in Vamenan village in Azadshar, various organs such as root, stem, and leaf were dried and powdered separately. Also, mixed organs were considered as another treatment for comparison. Then various organs of L. serriola and a mixture of them were analyzed qualitatively for primary metabolites like organic matter, raw ash, protein, proline, starch and soluble sugar as well as membrane stability index and some secondary metabolites like total phenols and anthocyanin. Results showed that various organs of L. serriola had a various content of primary and secondary metabolites as well membrane stability index. On the basis of the findings, the highest and lowest contents of organic matter and raw ash were obtained in leaf, respectively. The highest content of protein, starch and compatibility osmotic of soluble sugar and proline also were found in the leaf organ. The highest content of total phenols and anthocyanin were obtained in leaf showing a positive and significant correlation with membrane stability index. Regarding the high biomass generated from L. serriola, it is suggested to analyze the other chemical compounds in this plant. Complimentary studies are required to exploit the application of these compounds as bio herbicide. Manuscript profile

  Drought stress is a limiting factor in growth and production in more than 30% of the world's cultivated areas. One of the ways to deal with drought stress is to cultivate plants that are more resistant to this stress and cotton is one of these plants. There is little information about the physiological and biochemical properties of cotton under stress conditions and therefore this study was designed to identify the fluctuation of physiological characteristics and tolerance signals in mother seeds and seeds under drought stress in cotton plants. Experimental factorial, in the form of a randomized complete block design, in 5 seed treatments (including 4 levels of stressed seeds and non-stressed seeds) and stressed seeds at 4 levels of irrigation (rainfed, 33%, 66%) And 100% of the field capacity of the farm) was implemented. In this study, the seeds used were exposed to drought stress in 3 stages during different cropping seasons. The results showed that the effect of irrigation on yield and yield components was significant and the highest total yield was observed in 33% seeds under irrigation 33% of field capacity and the highest early maturity was observed in 66% irrigation. The results showed that severe drought and waterlogging reduce cotton yield and 33% seed after 3 years of exposure to moderate stress by stimulating physiological mechanisms and increasing the amount of osmolytes and antioxidant enzymes. And photosynthetic pigments became more adaptable to drought stress. The results of this study showed that the exposure of seeds to mild to moderate stress, strengthens the signaling pathways and increases the potential of seeds to tolerate drought stress, which can be considered by seed propagation centers.

  In order to evaluate of physiological activities in peanut (Arachis hypogaea L.) in response to different irrigation regimes and Ethanol foliar application, an experiment carried out as split plat based on randomized complete block design with three replications in experimental field of Agicutural and Natural Resources Research and Education Center of Guilan Province, Astara (Kanroud research station), Iran during 2018 and 2019 cropping seasons. Four level of irrigation regimes at 25, 50 and 75 and 100 mm evaporation from class A pan and three levels of Ethanol 10, 20 and 30 % (v:v), comprised experimental factors, as main plot and sub plot, respectively. The interaction effect beween irrigation regime and Ethanol alcohol was significant for all measuered characteristics in peanut at 1% probability level. Drought stress caused to decrease grain yield per unit area, leaf chlorophy index and leaf relative water content in peanut. But, drought stress increased the value of proline, soluble sugar, soluble protein, anthocyanins and the activitiy of catalase, superoxide dismutase and peroxidase enzymes. The greatest grain yield (3275 kh/ha) was obtained in response to irrigation regime after 25 mm evaporation fron “A pan” along with foliar application of Ethanol at the rate of 20% (v/v). In general, result showed that the foliar application of Ehanol could be recommendable in direction to enhance grain yield and resistance of peant plans againest to drought stress under similar climatic condition.
