        In order to study of interaction effects of salt and salicylic acid, it was used two cultivars of canola (Hayola 401 and RGS). Canola seeds were provided from Lorestan Agriculture Research Center in this experiment. After culturing seeds in experimental environment, the intact seedling transferred to Hogland half-power culture in the dishes with 650ml capacity. After 24 hours, the plants were placed under different treatment with the salt and salicylic acid. Canola plants were placed in determined rooms and in the light and the dark periods 16 and 8 hours respectively in order to ventilation the dishes were airing every day. The treatments were included 75,100,150mM salt and 5μM salicylic acid. After 20 days, catalase and peroxides activity were tested in the root and leaves of plant. With respect to the results achieved in this research, it was determine that when salinity stress increased, the amount of catalase and peroxidase activity increased. This increase in the roots was more than leaves in both cultivar of canola. With adding 5μM salicylic acid in above environment, it showed the increase of catalase and peroxidase activity, so this case helps to reduce destructive effects of salinity and balance its effects.

        In this article the effects of salt stress on the activity of antioxidative anzymes and lipid peroxidation were studied in shoots and roots of two cultivars of wheat. The cultivar Mahooti and Alamoot were selected as salt-tolerant and salt-sensitive, respectively. The plants were treated for 24, 48, 96 hours. Mostly salt stress increased the activity of superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) in treated plants. Also, the increase in level of CAT activity in roots was more pronounced in the salt-tolerant than in the salt-stress that is indicated the role of CAT for tolerance in Mahooti. The increase in activity of these enzymes during 24 hours of treatment with NaCl in salt-tolerant plants were more than in salt-sensitive plants. Lipid peroxidation had a little increase in treated plants, compared to those of the control ones. Salt stress had no significant effect on accumulation of Na+ in two cultivars. The results indicated that the oxidative stress play an important role in the activity of different enzymes in salt-stress and salt-tolerant plants. Also, rate of enzyme activities showed some flactuations, which suggest the cooperation of antioxidant enzymes with each other corresponding to different times and different stages of the growth.

        Khezr Abad area with 1146 hectares area is located in the west of dasht-e- Yazd – Ardakan and west and northwest of Yazd. This area has several water shed, that Orzanak is one of biggest them. The main object of this research is indentification of plant species and introduction of the flora in Khezr Abad (Orzanak). For this purpose, plant samples were collected from different habitats, of the area in three growing seasons, spring, summer and autumn of 2004 year and the then were identified by different floras. The life forms of species were determined and the biological spectrum of he area was plotted. The position of the region was studied with respect to phytogeographical classification based on geographical data and references. From 103 identified plant species are 1gymnosperms, 86 dicotyledones and 16 monocotyledones. They belong to 30 families and 86 genera. The following families have the highest number of species: Asteraceae (%20.4), Poaceae (%12.6), Lamiaceae (%9.7), Fabaceae (%8.7) and Rosaceae (%7.8). Hemicryptophytes with 40 species (%38.8) and therophytes with 23 species (%22.3) are the most frequent life forms in the area. The distribution of 71 species (%68.9) is restricted to Irano-Turanian region, 29 species (%28.1) of them are endemics of Iran. Among of endemic species, two species Nepeta gloeocephala and Helichrysum davisianum are endemic of Yazd. Manuscript profile

        In today, the use of growth regulators not only cause growth improvement and increase product of cotton but also rise resistant of this plant to environmental stresses. In this research the effect of drought stress and also drought with pix in different concentrations (0. 5, 1. 5 and 2. 5 L/ha) were used in form spray and control (irrigation) in reproductive phase on growth factors, amounts of chl a and b, soluble sugars and starch under condition of pots were evaluated. The results of this research showed that application of pix because decrease stems length in comparison to drought treatment and control. Other growth factors such as root length, number of internodes and bolls, dry and fresh weight of shoot in treatments of drought with pix different contents did not change significantly. Number of leaves also in drought with 1.5L/ha concentration of pix treatment decreased significantly in comparison to drought treatment Amounts of chl a and b did not affect under different treatments. On the other hand the most of amounts of soluble sugars and starch in leaves were observed alone in control and in plants root under drought treatment. In between other treatments these changes were not significant. Manuscript profile

        Seed protein analysis was performed among 10 cultivated genotypes (Amygdalus dulcis (L.) Miller genotypes: Moheb Ali, Safari, Yarollahi, Mamaei, Rabee, Kababi, Tageri, Hag Mirzaei, Talkheh and Azar) and 2 wild species of almond (Amygdalus scoparia Spach & A. lycioides Spach var. horrida (Spach) Browicz), from Esfahan province, in order to illustrate their interrelationships. All together, 18 protein bands were obtained, some of which were common in all species and cultivated genotypes. Some bands were occurred only in a single cultivated genotype or species, while, some others occurred in all local genotypes, but not in the wild species. The obtained data were analyzed through cluster analysis via UPGMA method and Euclidean distance coefficient, and through Principle Components Analysis (PCA). The results revealed that some local cultivated genotypes were similar, such as a close relationship was detected among the genotypes Safari, Yarollahi and Mamaei, as well as among Tageri, Hag Mirzaei and Kababi. Different patterns of protein bands were also observed between the genotypes and the wild species. As a result, the role of seed protein criteria in the genetic variations among studied genotypes and wild almond was discussed. Manuscript profile

        Different habitats don’t have the same effects on the growth of plants and different climates can influence the rate of efficient compounds of plants. So, we make a decision for researching about Urtica dioica L. that it’s a medicinal plant and in traditional medicine, it has been used for cure of many diseases. During the reproductive period of stinging nettle the sample of this plant was collected from four regions of Gorgan city situated in Golestan province. The ethanol extract of different organs of U. dioica L. was extracted and effected on three bacteries, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans, by using MIC and MBC method. The results of this study showed that ethanol extract has antibacterial and antifungal activity. Prepared extract from high altitude had more antimicrobial effects. It was clear that leaf had most efficient extract among these four evaluated organg (MIC: 62.5mg/ml) and in most cases, stem extract didn’t have antimicrobial effect or its effect was little. But E. coli excluded of this rule and its root extract always was the most efficient extract in all of the altitudes and had the best inhibitory and fatality (MIC 7.8 mg/ml, MBC 15.62 (mg/ml) effects.
