  This survey was undertaken in Golestan province in order to inventory of Tanacetum parthenium L. in traditional medicine for treatment of headache, cold, fever, menstrual, arthritis, anti infection and rheumatic pain. Flowers and leaves were collected in August 2006 from Deraznoo Mountain in south west of Golestan province and were water distilled to produce the oils in the yields of 0.66% (v/w) in flowers and 0.12 % (v/w) in leaves, respectively. The oils were analyzed by GC and GC/MS. In two regions, the major components in flower essential oil were camphor, alpha- pinene and alpha- bissabolol oxid-B, but camphor, alpha-pinene and piperiton were the major components in leaves of this plant.

This research was carred out in “Anbar-e-olom Saline Reasearch Station” in 35 km north of Gorgan, Golestan province at the agronomy year of 1384-85.The experiment was arranged in Split-plot Factorial was in a form of Randomized Complete Blocks Design (RCBD) in 4 replications including the main and secondary factors, on soil Clay Loam, pH8.2 and EC9.2 (dSm-1). The main factor included amounts of Sulphur (0, 500 & 1000 kg/he) and the secondary factors included the two seed size (Small and Large) and 3 genotypes of wheat (Zagros, Desconcido-7 and Kohdasht). Results showed that there was significant differences amounts the treatments and regarding (Sulphur, Seed size and Genotypes) such as, Grain yield, number of fertile stems per square meter, number of grains per spike, weight of kernel, Harvest Index (HI) of spike, HI of plant, weight of spike (gr/m2), number of spikelets per spike. By comparing the characteristics mean it was proved that using 1000 kg/ha sulphur was significant difference in grain yield parameter. Although using of sulphur 500 kg per hectare had effected more than amount not using (without sulphur) but it was not significant difference. Using the two different amounts of seed size (Large and Small) were significant difference with each other. And using of Kohdasht genotype was significant difference in grain yield parameters and as the second, Zagros genotype and as third, Desconcido-7 was significant difference with each other. Also as the reciprocal effects, Sulphur 1000 kg/ha, large seed size and Kohdasht genotype had the most amounts of grain yield and effect. Manuscript profile

This study aims at the evaluation of physiological aspects of two cotton (Gossypium hirsutum L) cultivars, Siokra and Sahel to salin soil salinity [EC=12.3] collected from natural environment of Golestan province. Field tests in three stages, consist of two, four and six foliair seedlings were performed. In leaves of both cultivars, from 1st to 3rd salinity stress, increased Na+, Cl- concentrations noticeably , indicating that salinity resistance was not associated with the ability of the plants to restrict ions uptake and accumulation. During the three vegetative growth stages, from 1st to 3rd, CGR, NAR K+ and Mg++ uptake in both cultivars decreased but increased production of proline and was higher in siokra cultivar. Effect of high salinity, was accompanied by increasing soluble sugars and decreasing insoluble sugars contents, in both cultivars. The content of glycine betaine decreased partialy from two to six foliair stage. Results determined that cotton is among plants that having production and accumulation sterategies of proline-glycine betaine spontaneously. High salinity of soil increased the importance of proline and soluble sugars for resistance of plant and decreased nonsoluble sugar content during growth stages. Manuscript profile

In different stress such as salinity, strong oxidant as Reactive Oxygen Species is produced that damages to membrane structure in plant. Different antioxidant as ascorbate scavenger them. In this research Soybean (Glycine max L. cv DPX) in different concentrations of ascorbate (1,2mM) and NaCl (50mM) and the effect of them on germination percentage, radicle length and antioxidant enzymes such as catalase, peroxidase, polyphenol oxidase and ascorbate peroxidase was evaluated. The results of this research showed that in absence of ascorbate and present of NaCl activity of enzymes increased but with increasing of ascorbate, activity of them decreased. Also in present of NaCl germination decreased but in NaCl and ascorbate germination increased significantly. Manuscript profile

Zinc is one of the essential micronutrients for the normal growth and development of plants. It is also known as heavy metal which at higher level causes toxicity in most of the plants. Nowadays environmental pollutions especially which caused by heavy metals result from industrial activity.Also the useage of chemical and inorganic fertilizer have non-compensated damage on the agricultural plants. Hence study of plants, tolerance to heavy metals is significant. The effect of high concentration of zinc on chlorophyll a and b, carotenoid, soluble sugars, starch and prolin in Brassica napus has been studied in this survey. Plants were treated with various Zn concentration (50, 100, 250, 500, 700 µ M) in nutrient solution for two weeks. All determinations were carried out in triplicate and data were statistically analyzed by using full randomize plots, SPSS v,13, MSTAC (one-way ANOVA) and Duncan test. According to the result chlorophyll a and b significantly decreased in comparison to control by increasing Zn concentration, but content of chlorophyll b was significantly decreased in treatments of 500 and 700 µM Zn. Also carotenoid,s content significantly decreased in concentration of 500 and 700 µM Zn. Soluble sugar increased in shoots and roots by increase of Zn as well as proline, but starch level were decreased in both. Manuscript profile

Cyanobacterium Nostoc sp. can be considered as an interesting microorganism for the ability of excretion buffering compounds. With respect to possible applied potential of this strain, this ability has been studied under limited irradiance. Soil samples were collected from paddy-fields during one year. At the first step, different acidities (pHs 5,7,9) were studied under limited carbon dioxide condition. Results showed that in all treatments, organism tends to enter logarithmic phase of growth until third day, but acidic condition cause sharp decline on growth after this. Highest specific growth rate belong to alkaline condition (pH 9). For the next step, two alkaline condition near to pH 9 (pHs 8.5 and 9.5), were selected to compare. Results showed that specific growth rate was significantly less than pH 9, and even continuous aeration couldn’t be able to enlarge specific growth rate. Pigment composition can be rearranged at different acidities and phycobilisome systems cause viability and growth under acidity fluctuations and limited irradiance in addition of low carbon dioxide concentration. Ammonium liberation showed the highest rate at pH 5 and day two too. Manuscript profile

Symbiosis with VAM under salt stress can affect on yield and growth parameters. In order to evaluate the effect of salinity (NaCl) and symbiosis of VAM on growth parameters and yield of sorghum (c.v.speed feed). The factorial experiment conducted based on complete block design with three replication and two levels of VAM. (Control (M0) and VAM (M1)) and three levels of salinity (0/8, 7, 14dS/m NaCl). Sorghum seedlings inoculation with Glomus intradices. Until emergence irrigated with (0/8dS/m) water and then treatment with saline water. Result showed that above ground length ,leaf area, dry weight stem and root, and shoot/root dry weight were significant (P<0.01), (P<0.05). Glycine betain (GB) content of leaf under different salinity and VAM levels was not significant but GB in root under salinity levels was significant (p<0.01) and VAM symbiosis and VAM*salinity interaction was not significant. VAM had not impact on GB content Manuscript profile
