  In order to study the effect of height and habitat on some biochemical features of Sambucus ebulus, an experiment was carried out in three cities in Golestan (Ramiyan, Tuskestan-Gorgan and Minoodasht),  three height levels (elevations above 1400 m, 700-600 More

  In order to study the effect of height and habitat on some biochemical features of Sambucus ebulus, an experiment was carried out in three cities in Golestan (Ramiyan, Tuskestan-Gorgan and Minoodasht),  three height levels (elevations above 1400 m, 700-600 m, and below 300 m), and on leaves, flowers and fruit with three replications in 2015. Total phenols, total flavonoids, and antioxidant activity were measured. The results showed significant effects of heights, region, and organs on biochemical features of the plants so that the interaction of effects of the region and height on the total phenol content and antioxidant activity and the interaction of effects of the region and organ on the total phenol content and on the antioxidant activity, and the interaction of effects of the height and organ on  the total phenol content and flavonoids were significant. Also, the interaction of effects of the region, height, and organs was significant on total phenol content and total flavonoids and antioxidant activities. Maximum and minimum total phenol contents were recorded in the leaves of the plants in low height of Tuskestan and in the flowers of plants at average height of Minoodasht, respectively. Also, the highest flavonoid contents were recorded in the flowers at low heights of Minoodasht while the lowest flavonoid content was observed in fruits of the plants at low heights of Tuskestan. The findings also suggest that the maximum antioxidant activity was observed in fruit of the plants at medium elevation in Tuskestan while the minimum content was recorded in leaves of the plants at medium height in Tuskestan. Overall, it can be conclude that total phenol and flavonoids decreased with an increase in the height and the highest quality was obtained from the plants grown at low heights. Manuscript profile

Stachys lavandulifolia is one of the medicinal plants from genus of Stachys and Labiatae with different medicinal properties that is widely found in Iran. This research was based on a completely randomized design with three replications to investigate the morphological characteristics and phytochemical properties in four habitats in Semnan, Razavi and North Khorasan provinces in 2014. Morphological characteristics such as plant height, wet and dry root and shoot weights, root length, number of total flowers, number of open flowers and leaf, leaf area, and chlorophyll content were measured at the time of flowering. Also, essential oil yield and percentage, total phenols, total flavonoids, and antioxidant activity were measured in flowering time. Morphological characteristics did not show any significant difference but essential oil yield and percentage showed a significant difference in different habits. The highes total phenol and antioxidant content were recorded for Shahrud and Mashhad, respectively. The amount of total phenol and flavonoid were determined in the leaves and the highest amount of antioxidant was recorded in flowers. Finally, the highest level of essential oil yield and percentage were recorded for Mashhad and decrease in the altitude and rainfall could be attributed increase in essential oil in Stachys lavandulifolia.

In order to study the effects of irrigation period and humic acid on some morpho-physiological and biochemical characteristics of Thymus vulgaris L., an experiment was conducted as split plots based on randomized complete block design with three replications at research farm of Baharan University of Gorgan, during growing season of  2016- 2017. Treatments were four levels of irrigation periods (every 3, 6, 9 days and everyday as control) and humic acid at three levels (0, 150, and 300 mg/l). Results showed that irrigation periods increased phenolic compounds, antioxidant activity, proline, and soluble carbohydrate. The effect of the longest irrigation period (every 9 days) increased 1.07, 0.016, 14.53, 1.87 and 3.82 percent of proline, phenolic compounds, antioxidant activity and soluble carbohydrate, respectively. Also the highest concentration of essential oils was observed with the every 6 days irrigation treatment showing 15% difference as compare with the control. On the other hand irrigation period decreased significantly shoot height and wet and dry weight. Moreover, humic acid had a significant effect on all characteristics under study. Also, interaction effect of humic acid and irrigation periods had significant effects on all traits except for phenolic compounds. Foliar application with 150 mg/l humic acid and every 9-day irrigation resulted in the maximum increase in thymol and antioxidant activities. The highest level of essential oils was achieved in 300 mg/l humic acid and every 6-day irrigation period. Maximum proline content was also recorded under 300 mg/l humic acid and every 9-day irrigation period. Generally, findings suggested application of 300 mg/l humic acid and every 9-day irrigation as economically the best treatment since under humic acid application and less irrigation water the same yield is achieved as under high water consumption.

In order to study the effects of irrigation and abscisic acid regime on physiological factors and gas exchanges of Lavandula angustifolia CV. Organic Munestead, a pot experiment was conducted as factorial based on randomized complete block design with three replications at Plant Production faculty of Gorgan University of Agricultural Sciences and Natural Resources, during growing season of 2016- 17. The treatments were four levels of irrigation regimes (30-40, 50-60, 70-80 and 90-100 percent field capacity) and Abscisic acid including three levels (0, 15 and 30 Mm/L). The results showed that irrigation regimes increase chlorophyll a, chlorophyll b, chlorophyll a+b, gas exchange and RWC. Abscisic acid had significant effect on all traits except of carotenoid content that except to efficiency of water consumption was Abscisic acid 15 Mm/L, the others were the highest in Abscisic acid 30 Mm/L. Also interaction effect of irrigation regimes and Abscisic acid was significant for all traits except of chlorophyll a+b. Abscisic acid 15 Mm/L spray and irrigation regimes 30-40 percent field capacity increase 25.04 and 38,75 in efficiency of leaf water consumption and efficiency of water consumption, respectively. Generally, Abscisic acid 15 Mm/L application and irrigation regimes 30-40 percent field capacity Introduces the best treatment, due to the lower consumption of water and the use of Abscisic acid in stress conditions, higher levels of Abscisic acid can be achieved in inducing drought tolerance.

Stachys lavandulifolia is a medicinal plant growing in different parts of Iran. Its flower and leaf infusions are used for treating diseases related to stomach and also as sedative for insomnia and stress. This research was carried out based on a completely randomized design with three replications to investigate the essential oil contents of leaf and flower obtained from four different sites (Shahrud, Ghuchan, Nyshabur, and Mashhad). Ethnopharmacological data were obtained from local people and the plant samples were collected from their habitas during flowering stage in spring 2014. Essential oils of the sample leaves and flowers were distilled using a Clevenger apparatus to determine essential oil percent and yield in each site. Furthermore, the essential oil components were determined with a GC/MS tool. Results of ethnopharmacological study showed that this plant has different local names in the sites under study but its general application was for reducing stress. The highest essential oil yield and percent and also dry weight were obtained from Mashhad. Also, the highest numbers of essential oil components of Stachys lavandulifolia flower (n=72) and leaf (n=82) were extracted from Nyshabur and Ghuchan, respectively with a maximum essential oil weights of 92.692 and 96.818, respectively. The highest values of major components including betapinene, betaphellandrane, and caryophyllene were obtained from Shahroud and the highest values of spathulenol and alfathujene were obtained from Ghuchan and Mashhad, respectively and these components were higher in leaves than in flowers. The highest quality of the essential oils was obtained from plants grown in Mashhad and Ghuchan habitats. Manuscript profile
