Research ArticleOpen accessIn the abstractEffects of Cement Dust on the Physiological Activities of Arabidopsis thalianaSaeid Abu-Romman, Jarrah AlzubiAir pollution exerts detrimental effects on plant ecosystems and restricts agricultural productivity. Cement dust is considered to be one of the most harmful air pollutants of industrial origin and is a limiting factor for plant growth and productivity. This study aims to uncover the impacts of cement dust on photosynthetic pigments, protein content, hydrogen peroxide (H2O2) accumulation, lipid per oxidation … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 4 · 17 Nov 2015 · 8,113 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Salinity, pH, Light Intensity on Growth and Lipid Production of Microalgae for Bioenergy ApplicationMonika Prakash Rai, Trishnamoni Gautom, Nikunj SharmaThe crisis of energy producing molecules (fuels) is expected to increase in future, which is currently produced from crude mineral oil. Biodiesel is most reliable, non-toxic, biocompatible liquid fuel that can replace the existing unsustainable sources of energy. Among all the known sources, microalgae display high potential for the production of biodiesel owing to their numerous benefits like higher biomass … …OnLine Journal of Biological Sciences, Vol. 15, Issue 4 · 5 Nov 2015 · 16,789 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysiological and Biochemical Evaluation of Fe-Efficiency in Fe-Deficient Maize GenotypesEntesar M. Essa, Sahar M. Zaghloul, Z.A. Salama et al.Iron (Fe) deficiency is prevalent particularly in calcareous soils of arid and semiarid regions. The present study aimed to investigate the response of eight local maize genotypes to Fe deficiency. In addition, a Fe- efficient (WF9) and a Fe-inefficient (ys1) indicator genotypes were used in this study. All genotypes were grown in growth chamber for 21 days in two levels … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 1 · 22 Apr 2015 · 7,280 accessesView PDFCite
Research ArticleOpen accessIn the abstractCOPPER STRESS ON CELLULAR CONTENTS AND FATTY ACID PROFILES IN CHLORELLA SPECIESG. Sibi, T.S. Anuraag, Geeta BafilaHigher photosynthetic efficiency and biomass production with rapid growth makes microalgae as potential candidates over other energy crops in many applications. Heavy metals influence the production of secondary metabolites and lipd content of microalgae in particular. A study was conducted using six Chlorella species under heavy metal exposure to evaluate the copper stress on biomass, cellular and lipid contents. Preliminary … …OnLine Journal of Biological Sciences, Vol. 14, Issue 3 · 20 Aug 2014 · 7,785 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVALUATION FOR SALT STRESS TOLERANCE IN TWO STRAWBERRY CULTIVARSW. Al-Shorafa, A. Mahadeen, K. Al-AbsiSalt stress conditions have been found to destroy the vital physiological process in plant where slower cell division and cell enlargement or both and limit mineral nutrient uptake with clearly nutritional imbalance. A greenhouse pot experiment was carried out at Agricultural Research Station, Mu’tah University, Jordan to evaluate growth responses and mineral composition of two strawberry cultivars to salt stress … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 14 Apr 2014 · 7,697 accessesView PDFCite

Research ArticleOpen accessIn the abstractINDUCES OF ANTIOXIDANT COMPOUNDS AND SALT TOLERANCE IN WHEAT PLANT, IRRIGATED WITH SEAWATER AS RESPONSE TO APPLICATION OF MICROALGAE SPRAYHanaa H. Abd El Baky, M. M. Hussein, Gamal S. El-BarotyWheat plants (Triticum aestivum L., cv. Giza 168) irrigated with either 10 or 20% of Seawater (SW) were treated with aqueous extracts of green microalgae Scenedesmus obliquus and blue green algae Spirulina platensis (AESO and AESP 20 g (dry weight)/L) in order to increase wheat salt tolerance. Treated plants showed higher ability to tolerate salt stress (10 or 20% SW) … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 7 Jan 2014 · 7,591 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECTS OF UV-B ON PHOTOSYNTHETIC PARAMETERS, LIPID PEROXIDATION, FLAVONOIDS AND GROWTH TRAITS OF CONOCARPUS LANCIFOLIUS (ENGL.)Patrice Suleman, Amina Redha, Mohamad Afzal, Redha Al-HasanConocarpus lancifolius is a perennial ornamental plant adapted to the semi-arid conditions of Kuwait. It accumulates most of its biomass during the stressful summer conditions which includes UV-B irradiation. The study evaluated equivalent UV-B irradiation intensities that plants would normally experience sometime during the course of a year in Kuwait.
