Abstract
Vegetation is one of the most important parts of natural ecosystems that in addition to express of the growth conditions, it also shows the influence of ecological factors on the environmental condition. Investigations of plant diversity of a country are necessary for studyingthe ecosystem, pasture, plant gene bank, agriculture and medicine. On the one hand, identification of plant species of different regions provide feasibility of doing of next studies in the different fields of biological science. In this research the flora of Tang sorkh region in the Kohgiloyeh county from Kohgiloyeh-va boyerahmad province has been investigated. The area of mentioned region is 5000 hectares and it is located in 30 kilometers from the east of Yasuj. Maximum altitude of the area was between 1800-2800 m. Our research has started by collecting the essential information of the region. The plants of region have been collected and prepared for studying. several floras were used for identification the specimens and they are preserved in Alzahra University herbarium (ALUH). This investigation showed that in the Tang sorkh region, there are 46 families, 145genera, 172 species that include 6/97% of phanerophytes, 5/23% chamephyts, 43/60%hemicryptophytes, 13/95% geophytes, 28/48% therophytes. Analyses shows that most of species of region belongs to the Iran-o-Turanian region which contanins 5/69% of region’s flora. 23 species are endemic to Iran, 20 of which are rare species, 30 species are medicinal plant, 22 of which are poison. Totaly about 172 species has identified. 20 species are recorded for the first time from this province.

Abstract
Purslane (Portulaca oleracea L.) contains valuable secondary metabolites such as Dopamin, Noradrenaline and Omega-3. This plant is used in various medicinal, food and hygienic industries as well as the treatment of different diseases such as diabetes, heart disease and pain relief. Callus induced from medicinal plants are used to increase the production of secondary metabolities in cell suspension culture and gene transfer. The purpose of this experiment was the study of different concentrations of BAP and 2,4-D of two explants from leaf and shoot tips to produce callus. Leaf and shoot tip explants were used in MS with different concentrations of BAP at three levels (0, 1 and 2 mg/L) with 2,4-D at three levels (0, 0.5 and 1.5 mg/L). Results showed that interactions between hormones and explants were significant in the percentage of callus induction, fresh weight and callus diameter at 1% level. The best result which was the leaf explant with 100% callus induction, 121 mg fresh weight and 5.106 mm callus diameter was obtained by the combination of BAP 2 mg/L and 2,4-D 0.5 mg/L. Shoot tip explants with 75% callus induction, 106 mg fresh weight and 3.03 mm diameter was obtained by the application of 1 mg/L BAP and 0.5 mg/L 2,4-D.

Abstract
Regarding the rising rate of esophageal cancer in some parts of Asia, including northern and northeastern regions of Iran, the identification of new anti-cancer compounds is essential to combat the disease. The relation between some plants metabolites and these endophytic microorganisms are well characterized. In the current study, the potentials of Ephedra endophyte bacteria for the inhibition of esophageal cancer cell line (KYSE-30) proliferation were investigated. A total of 54 endophyte bacteria (out of 70) were obtained from the sterilized surfaces of two medicinal plants, i.e., Ephedra intermedia and Ephedra foliata. Bacterial strains were then cultured in Tryptic soy broth (TSB) medium and, after 72 h incubation, the produced secondary metabolites were extracted by chloroform. Anticancer effects of secondary metabolites from theses bacteria on esophageal cancer cell line KYSE-30 were evaluated after 24, 48 and 72 h by MTT method. MTT assay results showed that only strain A1 had a cytotoxic effect on KYSE-30 cells. The IC50 amounts of this strain against KYSE-30 cell lines were equaled (µg/ml) to 346.4, 192.8 and 121.3 after 24, 48, and 72 hours, respectively. The molecular identification of strain A1 revealed that Microbacterium maritypicum (99.8% similarity) was the closest identified taxon to the strain studied. According to the promising ability of strain A1 to inhibit the growth of KYSE-30 cell line, the use of natural compounds produced by this bacterium to treat esophageal cancer was found to be applicable. However, more experiments are needed to confirm these results after purifying the ingredients, as well as conducting studies in animal cancer models.

Abstract
Successful germination is the main factor in proper establishment and seedling yield. Information on seed germination, in the face of temperature changes at the time of planting, is a way to identify more suitable cultivars for cultivation at the planting site. For this purpose, a factorial experiment was performed based on completely randomized design with 3 replications. This experiment was conducted to investigate the temperature changes on the germination and growth indicators of lentil cultivars at Khatam Al-Anbia University of Behbahan. The studied treatments included five lentil cultivars of Gachsaran, Kimia, Robat, Ziba and Bilehsevar, and the temperature levels were 20, 25 and 30 °C, similar to the autumn conditions of Khuzestan Province. The results showed that all the seedlings of investigated cultivars cultivated at temperatures of 20 and 30 °C had a significant decrease in all the investigated traits, i.e., germination percent, germination rate, germination vigor, seed vigor index, endosperm consumption, plumule length, radicle length, seedling length, plumule dry weight and radicle dry weight, in comparison with those seedlings cultivated in 25 °C. The study of the interaction of cultivar-temperature effects showed that Bilehsevar cultivar had the highest germination and growth indices at 25°C compared to other investigated cultivars. This increase in traits such as germination rate, germination vigor, seed vigor index, plumule dry weight and radicle length was more significant in Bilehsevar cultivar compared to other cultivars. The second rank of the highest germination and growth indices was assigned to Gachsaran cultivar under 25°C conditions, which had a significant increase compared to other cultivars (Kimia, Robat and Ziba). Considering the autumn cultivation of lentils and the changes of temperature in that season (temperature range of 20 to 30 °C) in the studied area, the use of Bilehsevar and Gachsaran cultivars under the temperature of 25 °C, due to their higher germination indicators compared to the other cultivars, i.e., Ziba, Kimia and Robat, could be recommended.

Abstract
The present research, a floristic study was executed on Imamverdy, Dartum, Ghapagh, Garivan and Niestaneh villages, located 30 km south of Bojnourd (North Khorassan province) with altitudinal range of 1442-1783 m. The present study aimed to identify the specimens, their possible medicinal properties, endemism and concervation status. For this purpose, the specimens were collected during March-November 2012 and identified using Flora of Iran and Flora Iranica. The results showed the presence of 133 species from 104 genera and 38 families, one species belonged to Gymnosperms and the rest, 132 species, belonged to Angiosperms, of which five families, 13 genera and 18 species were monocotyledons and 32 families, 90 genera and 114 species were dicotyledons. Moreover, 40 species were found to have medicinal applications in the studied region. Fabaceae, Brassicaceae, Poaceae, Asteraceae and Lamiaceae were the largest families and Astragalus, Poa, Vicia and Euphorbia were reported as the largest genera in the region. Erysimum koelzii, Astragalus khoshjailensis, Eryngium bungei, Acanthophyllum pachystegium, Sclerorachis platyrachis, Taraxacum hydrophyllum were endemic species for Iran. Astragalus ackerbergensis was found to be in vulnerable status and Rubia florida, Mentha longifolia, Fumaria vaillanti and Onopordum carmanicum were found to be at low-risk status. The maximum and minimum percentages of chorotypes were related to Irano-Turanian with 68.14% and Irano-Turanian, Saharo-Arabian regions with 0.7%, respectively. The maximum and minimum percentage of life form were reported to be hemicryptophytes with 45.8% and cryptophytes with 3%, respectively. The results reflected the cold and arid climate and uncontrolled grazing in the studied region.
