This study aimed to investigate the effects of different levels of Rosemary (0, 100 and 200 mg per kg) and peppermint (0, 100 and 200 mg per kg) essential oils on performance, internal organs and some blood indices using360 one-day old quail. The experiment was conducted in a 3×3 factorial arrangement based on a completely randomized design with nine treatments and four replications (10 birds per repetition). The results showed that the consumption of highest level of rosemary essential oil caused the increased feed consumption during week 2 of age (P<0.05). Peppermint essential oils affected the feed consumption during week 4 of age (P<0.05) and the quails fed with the medium peppermint essential oil (100 ppm) had the lower feed conversion ratio as compared to the other levels. Moreover, the results of the experiment showed that consumption of rosemary and peppermint essential oils alone or together had no effects on the breast, thigh, liver and spleen weights (P>0.05). The essential oils of rosemary and peppermint plants did not change the blood indices of triglyceride, protein, urea, creatinine and HDL (P>0.05). There was a trend for the effect of rosemary essential oil on length of both jejunum and ileum (P=0.09) and the 100 and 200 ppm rosemary caused the higher length of both jejunum and ileum at day 35 of age. In conclusion, the consumption of rosemary and peppermint essential oils improved the performance of quails in the early ages.

Jasmonates are key signaling compounds in plant responses to biotic and abiotic stresses as well as in development. We studied the role of methyl jasmonate (MeJA) in alleviating NaCl-induced salt stress in Mentha piperita L. through evaluating its growth, mineral and phenolics contents, essential oil (EO) quantity and quality. Accordingly, plants were exposed to the NaCl concentrations of 1.86 (control), 5, 75 and 10 dS/m for two weeks, 24 h after foliar application of 0, 60 and 120 µM MeJA. The results showed that salt stress decreased fresh and dry weights of aerial parts and concentrations of potassium (K+), calcium (Ca2+), magnesium (Mg2+), K+/ Na+ ratio and phenolic compounds, while sodium (Na+) content increased significantly under salt stress. Also, EO yield increased with the increase of salinity concentration then decreased at the salinity concentration of 10 dS/m. However, exogenous application of MeJA enhanced the contents of K+, Ca2+, Mg2+, K+/ Na+ ratio and phenolics, while Na+ content in salt stressed plants declined. In addition, pretreatment with 60 µM MeJA improved the growth and EO yield. The highest values of menthone and menthol were obtained at the salinity concentration of 7.5 dS/m and concentrations of 60 and 120 µM MeJA. In summary, our results indicated that application of MeJA could reduce the adverse of salinity stress in M. piperita.

Peppermint (Mentha piperita L.) from Lamiaceae family is one of the most widely used medicinal plants. In addition to therapeutic effects, it is used as flavoring in the production of various foods and medicinal products. In addition to genotype, the quality and quantity of active ingredients in medicinal plants are influenced by environmental factors. This research was aimed to study the effects of drought stress and jasmonic acid on the quality and quantity of peppermint as a factorial experiment in a completely randomized design at University of Zanjan in 2015. The treatments consisted of three irrigation levels [50%, 75%, and 100% (control) of field capacity] as main factor and three concentrations of jasmonic acid (0, 50, and 100 mg l-1) as sub-factor. Rhizomes of plants were used for plant production. The plant samples were collected at flowering stage and after drying in the shade, the essential oil was extracted with water distillation method by Clevenger apparatus. The essential oil components were identified by GC and GC-MS. The results showed that the highest fresh and dry weight, height, total chlorophyll and relative leaf water content were obtained in control with 100 mg l-1 jasmonic acid. The highest peroxidase enzyme content was obtained at 50% field capacity drought stress with 100 mg l-1 jasmonic acid. The highest essential oil content was obtained at 75% field capacity drought stress with application of 50 mg l-1 jasmonic acid. The main essential oil components were menthol, menthon, 1,8-cineole, cyclohexanol, and methyl acetate. The highest amounts of menthol, menton, and 1,8-cineole were obtained from 100 mg l-1 jasmonic acid and the highest amount of cyclohexanol was obtained from 50 mg l-1 jasmonic acid. However, application of jasmonic acid decreased the amount of methyl acetate from 7.24% in control to 0.56% in 100 mg l-1 of JA treatment.

This study was aimed to investigate the effects of manganese stress and salicylic acid treatments at three different times on activities of antioxidant enzymes, proline, soluble sugars, photosynthetic pigments and essential oils of Mentha piperita L. The research was conducted in a greenhouse at the University of Zabol in 2012-13. A factorial experiment was performed in a randomized complete block design with three replications. Plant samples were harvested at three times in 1, 3 and 5 days after spraying with Mn stress (500µM) and salicylic acid (1mM). The results indicated that manganese stress significantly affected APX and proline content of peppermint leaves during all three times. The content of proline and soluble sugars significantly increased in three times compared to the control treatment under salicylic acid and manganese stress. On the other hand, the Mn stress did not significantly decrease the photosynthetic pigments. In addition, essential oils increased with manganese stress and salicylic acid. This increase was much under salicylic acid treatment. According to the obtained results, increased APX enzyme and proline content were the physiological responses of peppermint against oxidative stress. It was also observed that salicylic acid acted as a powerful growth regulator and caused modification in manganese stress response in Mentha piperita.

To investigate the effects of nutrition systems on the yield and some traits of Mentha piperita L., this experiment was carried out in the experimental field of Kerman Agricultural and Natural Resources Research Center, during 2008 to 2010. A combined analysis of variance was performed using Randomized Complete Block Design with three replications by MSTATC statistical software and means were compared by Duncan test. The treatments were consisting of different levels of N, P and K (conventional system), mixture of different levels of NPK and manure (integrated system), different levels of manure (organic system) and control. The results showed that, the effect of nutrition systems on biological yield, economic yield, dry matter percentage, leaf length, leaf width, and plant height were significant. The yield increased with increasing the amount of nitrogen, phosphorus, and potassium. The yield of Mentha piperita in the integrated system was higher than that of other systems. Maximum fresh weight yield (38313 kg/ha) and maximum economic yield (5634 kg/ha ) were obtained in the first year from integrated system (120kg N, 90kg P, and 120kg K+5 tons manure per hectar). With increasing age of the plant, the fresh weight yield decreased to 15% and 63% in the second and third years, respectively. In the present experiment, the highest yield was obtained with application of 120 kg nitrogen, 90 kg phosphorus, 120 kg potassium, and 5 tons manure per hectare. The use of this plant in a plot of land more than three years will not be cost-effective.

In this research, the effect of different harvesting stages on essential oils content and composition of Mentha piperita L. and Salvia officinalis L. was studied. The rhizome of Mentha piperita was planted at 5 cm soil depth in the field of "Jangalkar Ferdos Company", 2008. The salvia seeds were received from Isfahan research center. Their seedlings were transplanted on the furrows of the main field. The experimental design was randomized complete blocks and the treatments included early, full and after flowering stages. The experiment included six treatments and three replications in a total of 18 experimental units. After drying the samples in room air condition and removing all woody parts, essential oils of both species were obtained by water-distillation method in three replications and then analyzed by GC & GC/MS. According to the results obtained from analysis of variance, the effect of different harvesting stages on oil yield of Mentha piperita (P<0.05) and Salvia officinalis (P<0.01) was significant. Comparison of treatment means showed that the highest percentage of essential oil (2/8%) was recorded in full flowering stage of M. piperita while S. officinalis had the highest percentage of essential oil in early flowering stage (3%), with a significant difference in comparison to the other stages. Analysis and Identification of essential oils components showed that the major constituents of essential oil in S officinalis were α-thujene (20/8%, 27/1%, 35/9%) camphor (29/2%, 14/6%, 17/2%) and β-thujene (15/1%, 14/6%, 4/1%) in early, full and after flowering stages respectively. The major constituents of essential oils in M.piperita at early, full and after flowering stages were menthol (27/7%, 26/9%, 27/0%), menthon (37/0%, 21/9%, 17/2%), and menthofuran (16/0%, 22/0%, 25/3%).

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.
