Of more than 400 plant species known to be likely hosts for the lac insect, about 113 host species are found to be successfully infested by the lac insect in India. Architecture of the plant tissue might be a crucial factor for these sap feeders, because for successful establishment, the insect has to pierce the plant tissue to reach the feeding site, viz., the phloem or the xylem tissue. \u0000Materials and Methods: Twenty-two diverse host plant taxa classified on the basis of lac yield and insect preference were considered. Anatomical and statistical studies were conducted using distance to the phloem from the stem periphery as a parameter. \u0000Results: Statistical observations showed that host preference and lac yield is independent of phloem distance. \u0000Conclusions: Other factors such as the contents of carbon, nitrogen, or certain secondary metabolites present in the host plant may be involved in lac insect-plant interaction, which warrant further investigation.","PeriodicalId":11848,"journal":{"name":"Eurasian Journal of Biosciences","volume":"6 1","pages":"32-38"},"PeriodicalIF":0.0,"publicationDate":"2012-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5053/EJOBIOS.2012.6.0.4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70599767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Priming is an effective technique that improves germination of several vegetables crop under saline condition. That's why, this experiment was carried to study the effect of seed priming with 5 g/L NaCI and KCI on germination and seedlings growth of safflower {Carthamus tinctorius) exposed to five levels of salinity (0, 5,10,15 and 20 g/L). \u0000Materials and Methods: Safflower seeds were soaked in solutions of NaCI (5 g/L for 12 h) and KCI (5 g/L for 24 h) at 20°C. Primed and non primed seeds were put to germinate in petri dishes and irrigated with saline solutions of five concentrations of NaCI (0, 5,10,15 and 20 g/L). \u0000Results: NaCI and KCI priming have improved germination parameters (germination percentage, mean germination time, germination index and coefficient of velocity) and growth parameters (radicle and seedling length, seedling fresh and dry weight and Vigour Index) of safflower under saline condition. \u0000Conclusions: The present study revealed that, under salt stress, NaCI and KCI priming could be used as a method to improve safflower seed germination. However, further studies are needed to highlight effects of NaCI and KCI seed priming on future growth and development of the culture.","PeriodicalId":11848,"journal":{"name":"Eurasian Journal of Biosciences","volume":"54 1","pages":"76-84"},"PeriodicalIF":0.0,"publicationDate":"2012-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5053/EJOBIOS.2012.6.0.9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70600028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In folk medicine, extracts of the roots and fruits of the plant have been used for the treatment of digestive disorders, healing scars, and to stop bleeding. In the present work, we report the presence of some phenolic compounds from the aerial parts of the plant. \u0000Materials and Methods: The air-dried powder of Prangos ferulaceae leaves were Soxhlet extracted, successively, with n-hexane, dichloromethane, and methanol. A portion of concentrated residue of methanol extract was fractionated with an SPE-C18 cartridge using different mixtures of methanolwater. The 40% methanol fraction was analyzed by preparative HPLC using a methanol and water gradient to afford 4 compounds. \u0000Results: The purified compounds using preparative HPLC were: a glucosilated coumarin, celereoside and three flavonoids, quercetin 3-O-β-glucoside, isorhamnetin 3-O-β-glucoside, and isorhamnetin 3-O-glucorhamnoside. The structures of the isolated compounds were elucidated by UV, IR, 1D, and 2 D NMR spectral data. Quercetin glucoside and isorhamnetin glucoside exhibited strong antioxidant activity in the DPPH test with an RC50 value of 36.2 and 64.4 μg/mL respectively. \u0000Conclusions: It can be concluded that the P. ferulaceae aerial parts contain antioxidant flavonoids and furanocoumarins and that the plants bioactivities and medicinal potential might be attributed to presence of these compounds.","PeriodicalId":11848,"journal":{"name":"Eurasian Journal of Biosciences","volume":"6 1","pages":"91-96"},"PeriodicalIF":0.0,"publicationDate":"2012-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5053/EJOBIOS.2012.6.0.11","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70599802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Excessive amounts of salt have adverse effects on soil physical and chemical properties and also on the microbiological processes. The soils of Pinus maritima, Pinus pinea, and Eucalyptus camaldulensis were found to be under salinity stress in the present study area. Thus, the carbon, nitrogen, phosphorus contents, microbial biomass, and carbon mineralization were determined in the soils sampled from the Tarsus-Karabucak Forest of the Eastern Mediterranean Region (Turkey). \u0000Method: Carbon mineralization of all samples was measured by the CO2 respiration method over 30 d at 28°C and constant moisture. \u0000Results: There were no significant differences in the carbon mineralization among the soils. The average fungi count in 1 g of air dried soils of P. maritima, P. pinea, and E. camaldulensis were found to be a 72000 colony forming unit (cfu)/g, 25300 cfu/g, and 28500 cfu/g, respectively. The total bacterial counts were 4x103 cfu/g, 10x103 cfu/g, and 7x103 cfu/g and the counts of anaerobic bacteria were 17800 cfu/g, 42900 cfu/g, and 27300 cfu/g, respectively. \u0000Conclusions: It is possible to conclude that salt, as an ecological factor, had no effect on microbial activity. This may be as a result of heavy rains which decreased the salt concentrations of the soil in the sampling region.","PeriodicalId":11848,"journal":{"name":"Eurasian Journal of Biosciences","volume":"6 1","pages":"121-126"},"PeriodicalIF":0.0,"publicationDate":"2012-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5053/EJOBIOS.2012.6.0.15","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70599706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we report how hormonal levels in barley cultivars respond to the toxic effect of boron, an essential plant micronutrient. \u0000Materials a n d Methods: Two different barley {Hordeum vulgare) cultivars (Vamik Hoca and Efes 98) were used as a study material. Boron was applied in three different concentrations (0,10, 20 ppm) to plants that had grown from seeds for four weeks. Plants were harvested, stem-root length and stem-root dry-fresh weight content were determined. For further analysis, chlorophyll, total protein, endogenic IAA and ABA content analyses were carried out. \u0000Results: According to the data obtained, plant growth and development decreased with increasing boron concentrations. With increasing boron concentrations, soluble total protein increased in both cultivars. Boron application led to increased endogenic IAA content in both cultivars. 10 and 20 ppm boron application led to increased endogenic ABA content in Vamik Hoca cultivar whereas endogenic ABA content decreased in Efes 98. Absence of boron application led to increased endogenic IAA and ABA content in both cultivars. \u0000Conclusions: As a result, the response to boron is different in the two cultivars and Efes 98 may be more resistant to the toxicity than Vamik Hoca cultivar.","PeriodicalId":11848,"journal":{"name":"Eurasian Journal of Biosciences","volume":"11 1","pages":"113-120"},"PeriodicalIF":0.0,"publicationDate":"2012-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5053/EJOBIOS.2012.6.0.14","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70599592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, green campuses have become rare places where the characteristics of the area flora can be observed. In this context, the aim of the present study is to identify the floral richness of the campus of the Buca Faculty of Education (BEF), an important floristic area within the city of Izmir, and to clarify how this richness is used in the educational processes. \u0000Method: The study was carried out between the periods 2008-2010. Plants growing on the BEF Campus constitute the research material. Plants growing on the campus were examined, necessary samples were collected. After the determination of plants, how they were used in B.Sc, M.Sc. and Ph.D. classes was investigated. For this purpose, interviews were performed with seven teaching staff from the Buca Faculty of Education Department of Biology. \u0000Results: A total of 108 plant taxa belonging to 52 families were identified in the campus area. Further study of the families showed that the family Rosaceae is represented by the highest number of taxa, fourteen, followed by Fabaceae represented by nine taxa. In addition, according to opinions of the academic staff, different ways of using such plants in training were identified and discussed. \u0000Conclusion: A principal conclusion to be drawn is that a general programme in Applied Biology and Ethnobotany should be made available to all students. When the increase of plant usage for medicinal purposes in recent years is taken into consideration, field studies related especially to ethnobotany can be a very useful specialisation for M.Sc. and Ph.D. students.

It is used in many Ayurvedic formulations, either singly or in combination with other herbs, meant for sleeplessness, epilepsy, hallucinations and anxiety. At least three different plant species viz., Clitoria ternatea, Convolvulus pluricaulis and Evolvulus alsinoides are used as the source of this drug in the different parts of the country. Because of increased demand and high price, shankhpushp i is often adulterated in the trade by other related species. Therefore, a reliable authentication method is needed to facilitate differentiation/ identification of the genuine material from its adulterants. The present study was aimed at developing RAPD-based markers for identification of C. pluricaulis, E. alsinoides and C. ternatea, and analyzing the market samples of the drug to ascertain their authenticity. Materials and Methods: Fresh samples of source plants of shankhpushp i were collected from Ghaziabad and Delhi. The market samples were procured from the crude-drug markets of different geographical regions of India. The amplified polymorphic D N A (RAPD) technique was employed for characterization of genuine and market samples. Twenty-five 11 -mer oligonucleotide primers were used to amplify the D N A isolated. Results: Out of 25 primers, only four (OPN-03, OPN-04 , O P N 0 5 and OPN-06) yielded amplification products that produced clear and reproducible bands, which were used to characterize the market samples. RAPD profile of some market samples did not match with the authentic samples, indicating that these samples were either adulterated or spur ious. Conclus ions: The RAPD markers developed in this study may provide guidance for the authentication of plant materials traded as shankhpushp i .","PeriodicalId":11848,"journal":{"name":"Eurasian Journal of Biosciences","volume":"6 1","pages":"39-46"},"PeriodicalIF":0.0,"publicationDate":"2012-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5053/EJOBIOS.2012.6.0.5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70600205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
