In this research, influences of environmental factors and methanol on seed germination and seedling emergence of Persian Fenugreek were studied. Optimum germination and emergence occurred within the constant temperature range of 20 to 24°C, pH range of 7 to 9, and planting depth of 1 cm, with light stimulating germination. The most water imbibition trend in time course was observed at 25°C. Germination was at least 37 and 55% when exposed to solution osmotic potential of up to-0.8 MPa and NaCl concentration of down to 200 mM, respectively. No germination was observed at osmotic potential of-1.0 MPa and NaCl concentration of 250 mM. With increasing NaCl concentration and osmotic potential, Hypocotyl length decreased but radicle length increased and then rapidly decreased. Immersion period treatments had no effect on seed germination but seedling growth was greater in treatment without immersing period. Maximum dry weight and radicle length significantly (P≤0.01) achieved at 4% and hypocotyl length at 2% methanol concentration. The possible role of methanol in stimulating growth in Persian Fenugreek seedling was discussed. Information gained from this study will further improve our understanding of the germination behavior of Persian Fenugreek and can contribute to developing sustainable strategies for its important cultivation. © 2011 Academic Journals.

Ducrosia Anethifolia is a threatened medicinal herb belongs to the family Apiaceae. This important medicinal plant is a native medicinal plant in Iran and has a restricted distribution in the world. It is used to treat of headache and backache in folk medicine. To callus induction, Leaf and lateral bud were used as explants and the Culture media was MS medium supplemented with 3% w/v sucrose, 0.7% w/v agar and 1gl-1 myoinositol at various concentration of cytokinins and auxins. After Five weeks, the calluses were transferred into regeneration medium that included MS medium supplemented with the combination of BA(0.5, 1 and 2 m gl-1) and NAA(0, and 0.5 mgl-1). The callus percentage, callus size and fresh weight, shoot length and number of shoots per explants were recorded. The analysis of variance showed that explants and media had significant effects on callus induction. The results revealed that the highest percentage (86.7%) of callus induction was created on MS media containing 2mg/l NAA and 1mg/l BA. On the other hand, lateral bud explants gave higher values in callus inducing percentage, fresh weight and size compared to leaf explants. In the case of plant regeneration, results indicated that the longest shoot length (21.6 mm) was exhibited for explants cultured on MS-medium containing 0.5mg/l BA and the highest number of shoots per explants(5.6) was obtained from callus grown on the medium supplemented with 2mg/l BA.

Gagea alexii Ali & Levichev (G. sect. Incrustatae Levichev) is recorded from the subnival zone of the southern mountains of Iran, the Hezar Mts. (Kerman province). Plant associates and some ecological aspects of the habitat of the species are discussed. A distribution map and expanded description of the G. alexii, including a cross-section of the peduncle is given. The morphological comparison of this species with its close relatives is also provided. The characters of the G.sect. Incrustatae and a key for specific identification are presented. The occurrence of this species in the subnival zone of the Hezar Mts. is a further evidence of the close floristic affinity of the southeastern Zagros with the Hindu Kush and Central Asia especially at high altitudes.

A new species, Nepeta sahandica Noroozi & Ajani (Labiatae), is described and illustrated from the high altitudes of the Sahand Mountains in northwestern Iran. Morphological differences of this species from its closest relatives in Nepeta L. sect. Capituliferae (Benth.) Pojark., N. lasiocephala Benth. and N. monocephala Rech.f., are discussed. These species differ mainly in their respective habit, basal and stem leaves, indumentum, and character of bract and calyx. The new species is restricted to the subnival vegetation zone, associated with unstable scree grounds. Nepeta sahandica is classified as Critically Endangered (CR), based on IUCN Red List criteria.

Background: Phthalate, esters of phthalic acid, are mainly applied as plasticizers and cause several human health and environment hazards. The essential oils of Achillea species have attracted a great concern, since several biological activities have been reported from varieties of these medicinal species. On the other side, due to the problems regarding the waste disposal in developing countries, phthalate derivatives can easily release from waste disposal to the water and soil resulting in probable absorption and accumulation by medicinal and dietary plants. As a matter of fact, although the toxicity of phthalate derivatives in human is well-known, food crops and medicinal plants have been exposing to phthalates that can be detected in their extracts and essential oils. Achillea tenuifolia (Compositea) is one of these herbaceous plants with traditional applications which widely growing in Iran. Finding: The plant root was subjected to hydro-distillation for 4 h using Clevenger type apparatus to obtain its essential oil before and after acid treatment. Both of the hydro-distilled essential oils were analysed by GC-MS method resulted in recognition of their constituent. Phthalate contamination as (1, 2-benzenedicarboxylic acid, bis (2-methylpropyl) ester (5.4%) and phthalic acid (4.5%), were identified in the first and second extracted oils, respectively. Conclusion: As a warning, due to the potential role of phthalates to cause reproductive toxicity, disturb of endocrine system and causing cancers, medicinal plants have to be considered through quality control for detection of these compounds. © 2014 Manayi et al.; licensee BioMed Central.
