Rosa damascena Mill is cultivated in different parts of Iran, and essential oil and rose water in large scales are produced. Essential oil is used in aromatic, food and cosmetics industrials. In this study, esential oils were extracted by hydrodistillation method, from Rosa damascena Mill. Genotypes (6A and 188B) collected from Kashan (Ghamsar) and west Azarbaiejan (Oskoo), respectively and cultivated in Research Institute of Forests and Rangelands. Samples were analyzed by GC and GC/MS. The main constituents in Ghamsar sample were n-nonadecane (25.5%), citronellol (17.7%)and geraniol (13.3 %) and for Oskoo sample were citronellol (27%), geraniol (18%) and n- nonadecane (14.2%). An appropriate was therefore genotype identified with high percent of major essential components, from Oskoo, despite cultivation in a different envirment from its geographical origin.

This study was conducted in a greenhouse located at the Research Institute of Forests and Rangelands. The responses of genotypes of 3 Mentha species to salinity stress regarding rooting ability as well as other growth parameters, were evaluated, using a completely randomized design, based factorial design in 3 replications. Stem cuttings of 6 Mentha genotypes, including 28 and 3 (M. piperita L.), 6 and 31 (M. aquatica L.), and 11 and 17 (M. spicata L.) were grown in 0, 50, 100, 150 and 200 mM NaCl solutions. Rooting percentage, maximum root length, average root length, plant vigor, bud induction in saline water, maximum shoot length and shoot bud induction were measured 14, 21 and 28 days after cutting. The results showed that all of the above parameters were reduced with increase in NaCl concentration. However, there was a considerable variation for salt stress responses. All of the characteristics, particulary rooting percentage showed to be singificantly different in the salt treated genotypes, with the highest rooting ability in genotype 6 under 200 mM NaCl. Also, a positive correlation was observed between rootig percentage, as well as between the other parameters. The variation in growth components detected between genotypes, and the correlation between the traits, support a suggestion for breeding of mentha species of higher salt tolerance for cultivation under salinity stress.

Antibacterial effect of essential oils of thirteen genus of cultivated Eucalyptus in the Fadak station of Dezful on E.coil, St. aureus, B.cereus and L. monocitogenes were studied. The essential oils of leaves were obtained through the hydrodistillation method. The rates of essential oils to dry matter of leaves were registered. The methods od disc diffusion and tube concentration were used to evaluate the microbial growth inhibition effects of essential oils. The essential oils had weak (+), mild (++) and good (+++) effects against the St. aureus. The minimum inhibitory concernation was ½. Against the E.coil weak (+) and mild (++) effects of the essential oil were registered. M.I.C. was ½. In B.cerus weak (+), mild (++), good (+++) and very good (++++) effects of essential oils were shown. The M.I.C. was 1/8. Also the essential oils had weak (+) and mild (++) effects against the L. monocitogenes. Research on herbal antibacterial agents is important, considering the limitation of the use of chemical antibacterial agents, and increasing development of herbal antibacterial agents.

In order to determine which plant species are producers, and which insects are affective in production of manna of tamarix this study was done in shahdad region that is placed in north east of Kerman province. Manna of tamarix is the sap of Two species of Tamarix (Tamarix aphylla & T. leptopetala) secretes on their adolescent branches from small stings on their skins made by two kinds of insects (Euscelisdecoratus & Tuponia subaltera), mostly Euscelisdecoratus. Habitats of producer species begin in the north of Shahdad city and extend in a southerly direction to south corner of Kerman province ending up in Narmashir-e-Bam. This region has a very arid climate and lies in the western side of Kavir-e-lout desert. Average annual precipitation is less than 50 mm and average annual temperature is over 25 degrees centigrade. Rural children and women collect manna yield from October to January in shahdad region. They consume it as a sweet or a traditional medicine to treat cough.

In order to investigate sowing date and cultivar effect a split –plot design was arranged in randomized complete block with four replication carried out in natural resources research station of kerman research center. Main plots were included four sowing dates (15Mar and 30Mar and 14Apr and 29Apr) and sub plots were included three cultivars (Cv.kerman, arak 2811,Esfahan native). From planting to total growth stages the following parameters (seedling, stems, bottom, flowering, and maturation) were effected with plant date and were reduced with delay in planting. Effect of plant date on plant height, sub branch number, heads per plant, seed weight, dry weigh of plant, seed yield and flowering, oil, and protein yield was significant and all of them reduced with delay in plant. Seed protein percent was increased with delay in planting and also seed oil increased with acceleration in early planting. The results showed that interaction between plant date and cultivar on plant height, sub branch number, heads per plant, seed number per heads, seed weight, biological yield, seed yield, oil yield, protein yield, percent of protein and oil was significant but in harvest index wasn’t significant. The second plant date 30March and CV.kerman are suitable for seed yield and Esfahan native cultivar is suitable for seed oil and recommend for planting and producing in Kerman climate condition.

There are few reports on antidiabetic effect of chard in traditional medicine. Therefore, its hypoglycemic and hypolipidemic effect was investigated in an experimental model of insulin-dependent diabetes mellitus. For this purpose, male Wistar rats (n = 34) were divided into 4 groups, i.e. control, chard-treated control, diabetic, and chard-treated diabetic groups. For induction of diabetes, streptozotocin (STZ; 60 mg/Kg; i.p.) was used at a single dose. A serum glucose level higher than 250 mg/dl was considered as diabetic state. The treatment groups received oral administration of chard-mixed pelleted food at a ratio of 1/15. Statistical analysis of the data showed that serum glucose level in diabetic group increases 2 and 4 weeks after the experiment as compared to data one week before the experiment (P<0.001), while this parameter was significantly lower 2 and 4 weeks after the experiment in chard-treated diabetic group as compared to untreated-diabetic group (P<0.01 and P<0.001 respectively). In addition, triglyceride level was higher in diabetic group and there was a significant reduction in this parameter in chard-treated diabetic group as compared to diabetic group in fourth week after the experiment (P<0.05). Meanwhile, cholesterol level showed a significant reduction in chard-treated diabtic group in comparison with untreated diabetic group. Taken together, the results of this study clearly showed that oral administration of chard could significantly reduce serum glucose, triglyceride, and cholesterol levels in diabetic rats. Therefore, this medicinal plant is strongly recommended for attenuation of some diabetic complications due to hyperglycemia and hyperlipidemia.
