Background: As application of chemical fertilizers has been recognized to cause pollution soil, water and agricultural products, today bio-fertilizers are an alternative to mineral fertilizers for increasing soil productivity and plant growth in sustainable agriculture. Objective: To determine the effects of biological and chemical fertilizers on qualitative and quantitative yield of Shirazian Babooneh (Matricaria recutita L.) Methods: This study was done in a randomized complete block design with three replications and six treatments along 2009-2010. The treatments were A (Control or no applying fertilizer), B (Bio-fertilizer as Nitroxin+ 53 Kg/ha chemical fertilizer), C (Biofertilizer as Super nitro plus + 53 Kg/ha chemical fertilizer), D (Bio-fertilizer as mix of Super nitro plus & Nitroxin + 35 Kg/ha chemical fertilizer), E (Bio-fertilizer as Bio-sulfur) and F (106 Kg/ha chemical fertilizer). Results: The fertilizer treatments had significant effects on plant height (p<0.05), plant dry weight (p<0.05), capitol diameter (p<0.01), fresh weight of capitol per ha (p<0.01), dry weight of capitol per ha (p<0.05), essential oil yield per ha (p<0.01), chamazulene content (p<0.01) and total flavonoid content (p<0.01). The chemical fertilizer had not significant effect on qualitative and quantitative yield of Shirazian Babooneh and the lowest qualitative and quantitative yield of Shirazian Babooneh was related to control (A) and chemical fertilizer (F) treatments. Although, the application of bio-fertilizers significantly increased the yield in respect of all studied parameters, the highest dry weight of capitol and content of essential oil were observed in biosulfur (E) treatment. Conclusion: The application of the bio- fertilizers increased qualitative and quantitative yield of Shirazian Babooneh and Bio-sulfur treatment was the best treatment. Also, the application of the bio- fertilizers can be in order to reduction in application of chemical fertilizers in agro-ecosystem which is attitude toward minimize of environmental pollution and sustainable agriculture.

Background: Acne vulgaris, a common skin disease, is a chronic inflammation of the pilocebaceous units; these areas include the face, the upper part of the chest, and the back. Antibiotices that inhibit "propionibacterium acne" are the selective treatment for acne. Now, because of antibiotic resistant, treatment is less effective. Therefore finding the alternative cure is nessesary. Objectives: The goal of this study is the comparison of arnebia solution effect with placebo on the treatment of mild to moderate acne. Methods: This study has been designed as double blined clinical trial on 68 patients with mild to moderate acne. The patients were divided in two groups. Pregnant and milk-feeding women, childeren with the age less than 12 years and patients that received related drugs to acne have been excluded from this study .The groups were treated topically with arnebia and placebo solution two times per day for 8 weeks. The inflammatory and non inflammatory lesions and the side effects were assessed in both groups. Results: These finding show that the arnebia solution was decreased the inflammatory signs, significantly (p<0.001). In this period of time no adverse effect was seen. Conclusion: In conclusion the arnebia solution was effective in the treatment of mild to moderate acne.

Increasing from day to day tendency of human societies to plant based drug usage increased demand of secondary metabolite application. Although artificial production of these compounds greatly progressed, but the only way to achieve these fine medicinal compounds has been to extract them from plant resources. Alkaloid field, although very old, is still in its infancy with regard to being fully understood, and biotechnologically exploited. Up to now, approximately 5000 different alkaloids, in 15% of plants that belong to 150 families, have been recognized, that tropane alkaloids such as hyosyamine, scopolamine, atropine and cocaine, with a broad medical usage are a class of them. Industrial tropane alkaloid production by modern techniques such as cell and tissue culture, somatic hybridization, metabolic engineering and commercial large scale culture, is highly concerned nowadays and in this review, the authors have tried to point out some of the results obtained by application of these techniques.

Saffron is highly valued for its unique aroma, taste, colour and medicinal properties. Iran is known, as one of the most important saffron producing countries but the genetic variability present in crocus in Iran is currently unknown. The main objectives of our research were: (1) evaluate phenotypic diversity among Iranian saffron populations; (2) compare phytochemical content between populations originating from different ecological areas; (3) determine possible correlations between phytochemical content and morphological traits; (4) identify yield-related traits for use in clonal selection programs and (5) estimate the broad sense heritability (hb 2) for the traits evaluated. In this study a combined analysis of variance was used to evaluate eight Iranian populations of Crocus sativus over a two-year period. The investigated characters were leaf number per plant, leaf length, flower number per plot, dry stigma weight per plot, spathe number and the content of crocins, picrocrocin and safranal. Statistical analysis showed that population had significant effect on most morphological parameters except leaf length and spathe number. Also it had significant effect on all phytochemical contents. Duncan's multiple range tests showed that populations were significantly different for most evaluated traits. Simple correlation analysis showed that dry stigma weight had significant and positive correlation with leaf number, flower number, picrocrocin and safranal (r = 0.954, 0.998, 0.830 and 0.881, respectively). The estimates of broad sense heritability were higher for flower related traits (hb 2 = 0.76 - 0.99). Cluster analysis did not reveal a clear relationship between diversity pattern and geographical origin. © 2010 Elsevier B.V. All rights reserved.

Madder (Rubia tinctorum) is highly valued for antheraquinone pigments produced in its underground parts. Iran is known, as a main producer of madder. Genetic variability present in madder in Iran is not unknown. The main objectives of our research were (1) evaluate phenotypic and molecular diversity among Iranian madder populations; (2) compare dye content between populations originating from different ecological areas; (3) determine possible correlations between dye content and morphological traits; and (4) estimate the broad-sense heritability (h2 b) for the traits evaluated. In this study a combined analysis of variance was used to evaluate 12 Iranian populations of madder over a 2-year period. Traits investigated were root weight, shoot weight and dye content. RAPD markers were also used to evaluate molecular diversity. Statistical analysis showed that population had significant effect on all evaluated traits. Duncan's multiple range tests showed that traits evaluated were significantly different among populations. Simple correlation analysis showed that shoot weight had significant positive correlation with root weight and also with dye content (r = 0.534 and 0.493, respectively). The highest estimate of broad-sense heritability was that of shoot weight (h2 b = 67.2%). Cluster analysis based on agro-morphological/phytochemical traits or RAPD markers did not reveal a clear relationship between diversity pattern and geographical origin. Furthermore, no association between agro-morphological/phytochemical diversity and molecular diversity pattern was detected. In conclusion genetic diversity of Iranian populations of madder as shown in this study should play a critical role in future selection and breeding of madder. © 2010 Elsevier B.V.

In arid and semi-arid regions where water availability is a major limitation, using plants with low water consumption is one way to manage available water efficiently. Chamomile (Matricaria recutita L.) may be considered as an economical crop for fields with water scarcity due to its considerable adaptability to a wide range of climates and soils. A field experiment was conducted during 2007-2008 using complete randomized block design with four replications in order to evaluate the effect of drought stress on agro-morphological characters (fresh flower weight, dried flower yield, shoot weight and root weight), oil content, oil composition and apigenin content of chamomile. Drought stress had four different levels of soil moisture depletion (30%, 50%, 70% and 90%). Analysis of variance showed that drought stress decreased plant height, flower yield, shoot weight and apigenin content but it had no significant effect on oil content or oil composition. Impacts of drought stress on growth indices were evaluated as well and the results indicated that plant managed to maintain potential for biomass production under the drought stress. Growth analysis results as well as phytochemical properties of this plant showed that despite decrease in agronomical traits, chamomile could be proposed as a moderate drought resistant medicinal plant with a reasonable performance. © 2010 Elsevier Masson SAS.

Background: The study of allelopathic properties of plants is one of up-to-date biological and ecological methods, which can lead to discover the bio-herbicides and growth inhibitors. Objective: In order to study the allelopathic effects of harmal (Peganum harmala L) on seed germination and seedling growth on purslan (Portulaca oleracea L.) and black weed (Chenopodium album L.), these experiments were conducted. Methods: The aqueous extracts of harmal different organs including capsule, leaf, stem and root were applied at five concentration levels (0 as control, 1, 5, 10 and 15%) through a factorial experiment based on a completely randomized design with three replications. Results: The results showed that different organ extracts had different negative effects on seed germination and seedling growth of the two species in such a way that capsules extracts had the highest inhibitory effect. With increasing extract concentrations of harmal, the seed germination and seedling growth of the two species was reduced significantly. The minimum amount of seed germination and growth of the seedlings were observed at 15% extracts concentration of capsules. Also, purslan seedlings appeared to be more sensitive to harmal extracts than black weed seedlings. Conclusion: The aqueous extracts of harmal different organs had inhibitory effects on seed germination and seedlings growth of purslan and black weed. Also, the highest inhibitory effects were related to capsule extracts.

More than 12,000 alkaloids are known in plants, mostly used as medicine with a world market value of about 4 billion US$. Opium poppy, Papaver somniferum, is the most important economic source of morphinane alkaloids such as morphine, codeine, thebaine, narcotine and papaverine that are exploited by the pharmaceutical industry as analgesics, antitussives and anti-spasmodics. With regard to increasing demand for these compounds, the aim of this review is presenting an outlook of classical breeding programs that successfully applied for enhancing the alkaloid content of opium poppy. The latest biotechnological approaches also are discussed to give an outlook for future trends and possibilities.
