Background & Aim: Saffron (Crocus sativus L.) formerly was important in Turkey. Saffron cultivation has been decreased and it is now only cultivated in three villages in this country. It is triploid and exclusively propagated in a vegetative way by corms. In Turkey, saffron is traditionally planted by placing corms in rows randomly without grading or sorting; which results in placement of corms in vertical, horizontal and reverse in rows at random. The study aimed to find the effect of corm size and position of placement in rows on stigma and corms yield.Experimental: This study was done at the experimental fields of the Department of Field Crops, Faculty of Agriculture, Ankara University, during 2010-2011 using four different corms size and three placement positions in three replications.Results & Discussion: The results revealed that position of corms and their size had significant effect on stigma yield. Whereas, corm yield was influenced by corm size only.Recommended applications/industries: According this study, vertical placement produced more stigma yield than other ones in planting. Vertical placement corms in rows should be practiced to obtain more stigma yield.

Background & Aim: Jasmonic acid (JA) is regarded as endogenous regulators that play important roles in regulating stress responses, plant growth and development. Effect of foliar application of JA on the essential oil and oil chemical components of hyssop (Hyssopus officinalis L.) were investigated.Experimental: This study conducted in a CRD with three replications and in experimental greenhouse, I.A.U., Shahrekord Branch, Iran at 2012. Experimental treatments included (I) water foliar application (control), (II) water+aceton foliar application (as a solvent), (III-V) 50, 100 and 200 JA mL. The essential oils obtained by hydro-distillation were analyzed by Gas Chromatography-Mass Spectrometry.Results & Discussion: The results of GC-MS showed that the major components of the oil were cis-3-pinanone (10-39%), trans -3-pinanone (4-28%) and b-pinene (27-34%). The results of analysis of variance of the experiment showed that different levels of the foliar application of JA do have significant impacts on chemical constitutes in the essential oil. Finally, foliar application of 200 mL JA on some of secondary metabolite production in H. officinalis oil could be partially changed.Recommended applications/industries:Abbreviation: JA: Jasmonic Acid, MJ: Methyl Jasmonate, GC-MS: Gas Chromatography-Mass Spectrometry mL: Micro liter, M: Molar; ANOVA: Analysis of Variance, CRD: Completely Randomized Design.

Background & Aim: The purpose of present study was to examine and validate the folk's claim of inhalation of Monechma ciliatum seeds powder by traditional African natives for cold and allergic conditions, so as to formulate a useful therapeutic agent to respiratory tract infections.Experimental: Different extracts were bioassayed in- vitro for their bioactivity to inhibit the growth of pathogenic bacteria and fungi. Bacteria and fungi selected in the study were common pathogens for respiratory tract infections.Results & Discussion: Klebsiella pneumoniae was highly sensitive to the hydroalcoholic extract (maceration by 70% ethanol 30% water) and moderately sensitive to the extract (maceration by water). Staphylococcus aureus was found to be moderately sensitive to the hydroalcoholic extract (maceration by 70% ethanol 30% water). Pseudomonas aeruginosa was resistance to all extract used. In addition, all fungi used were found to be resistance to all extracts. Phytochemical screening test results of seeds of Monechma ciliatum to detect the major constituents showed the presence of flavonoids, tannins, triterpens, and anthraquinones. The findings of study support the traditional uses of the plant in the therapy of respiratory tract infections.Recommended applications/industries: The extracts of black mahlab could be used in future direction as alternative therapeutic agents for the treatment of human's respiratory tract infectious diseases caused by Klebsiella pneumoniae and Staphylococcus aureus.

Background & Aim: Knowledge of the traditional application of plants is declining faster than the plants themselves; this study was conducted to record and store the local knowledge and cultural outcomes for using the medicinal plants in treating diseases in Mobarakeh region, Isfahan, Iran.Experimental: This study has done based on applying the desert survey, information of local people, and identification, classification and introducing these plants. Then the plant species were collected and transferred to the department of botany in Isfahan Research Center for Natural Resources in order to be identified after drying and preparing their herbarium.Results & Discussion: Finally, 200 plant species were identified; from which 75 ones, belonged to 73 genera, and 33 families with medicinal properties, were identified. From this number, 75% are herbaceous, ten percent shrubby and 15 percent are arboreous. The highest number of medicinal species belongs to the Lamiaceae family with nine species, Asteraceae family with eight species, Rosaceae family with six species, and the families Apiaceae, Papilionaceae, and Brassicaceae with five species. These plants are used in traditional medicine for treatment of gastrointestinal ailments, relaxation, cough, diarrhea, low blood sugar, and hyperlipidemia.Recommended applications/industries: According to results of this study, the preservation and conservation of some herbs species is essential. This document can play a role in preserving the indigenous knowledge of using these plants.

Background & Aim: Aflatoxin is the most important fungus that contaminates food and feed and can enter the food chain of humans. The aim of this study was to investigate the ability of thistle seeds (Silybum marianum L.)to reduce the adverse effects of aflatoxin B1(AFB1) on the immune system, variables related to the intestine, appearance and mortality of the broiler chickens.Experimental: In this experiment, a total of 216 Ross 308 broilerchickens in a completely randomized factorial design 3×3 with nine treatments, fourreplications, and six chickens unit were grown on the ground for 35 days. Treatments, included three levels of AFB1(0, 250, and 500 ppb) and three levels of thistle (0, 0.5 and 1%). Influenza and Newcastle diseases titers in two steps (25 and 34 days), variables related to the intestine at the end of the experiment along with the weekly appearance and mortality of broiler chickens were evaluated.Results & Discussion: Analysis of IDV and NDV results in the day 34 showed a reduction in titers of them in birds receiving diets contaminated with 500 ppb AFB1 (P£0.05). Also, The length of the ileum and the total intestine at the end of the experimental period (day35) indicated decrease in the group of birds received diets containing 500 ppb AFB1 (P£0.05). Chicks receiving diet containing 500 ppb of AFB1 had the most of feather abnormalities, aggressive behavior and minimal body size compared with other treatments. Mortality due to AFB1 consumption in various experimental treatments was not significant.Recommended applications/industries: Probably phitosomes of Silibummarianum seeds reduce the mortality rate, nervous and aggressive behavior and increase the immunity of broilers against Newcastle and influenza diseases in aflatoxin exposure time.

Background & Aim: Tragacanth is a natural gum obtained from the dried sap of several species of Middle Easternlegumes of the genus Astragalus, that is a viscous, odorless, tasteless, water-soluble mixture of polysaccharides. Tragacanth is used in pharmaceutical and foods industries as an emulsifier, thickener, stabilizer, and texturant additive.
