EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,527 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Water-Soluble Polymers for Extraction Separation of Amino Acids of Various StructuresNadezhda Yakovlevna Mokshina, Dmitry Vladimirovich Bykovskiy, Gennadiy Valentinovich Shatalov, Oksana Anatolievna PakhomovaThis article actualizes the task of developing new methods for extraction separation of amino acids for the analysis and purification of target components in the production of food supplements, pharmaceuticals, agricultural products and cosmetics; it also presents the extraction separation results for binary mixtures of histidine, proline and methionine using water-soluble homo- and co-polimers with various molecular weight values. We … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 10 Dec 2015 · 6,646 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnumeration of Microbes and Gas Production During Denitrification and Nitrogen Fixation Processes in SoilA. E. Ghaly, K. N. MacDonaldDry plant material contains 2-4% nitrogen, making it an essential nutrient for all plants. The nitrogen cycle regulates the pathways which transform nitrogen from a relatively inert dinitrogen gas to forms of organic nitrogen such as proteins and nucleic acids. Denitrification and nitrogen fixation are the two most important processes that remove and add nitrogen to the soil, respectively. The … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 11 Sep 2012 · 8,622 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiodegradation of Phenolic Compounds in Creosote Treated Wood Waste by a Composting Microbial Culture Augmented with the Fungus Thermoascus aurantiacusAbdel E. Ghaly, Bopeng Zhang, Deepika DaveProblem statement: Creosote is used as a wood preservative and water proof agent in railway sleepers, utility poles, buildings foundations and fences and garden furniture. It is a mixture of over 300 hydrocarbons which include 75% polycyclic aromatic hydrocarbons, 2-17% phenolic compounds and 10-18% heterocyclic organic compounds. Exposure to creosote may result in several health problems including damage to kidney, … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 2 · 26 Aug 2011 · 9,453 accessesView PDFCite
Research ArticleOpen accessIn the abstractRoot Elongation, Root Surface Area and Organic Acid by Rice Seedling Under Al3+ and/or H+ StressA. Elisa Azura, J. Shamshuddin, C.I. FauziahProblem statement: Under acidic condition, Al3+ is the most common species in solution. An experiment was conducted to study the effects of Al and/or pH on rice seed germination, root morphology and organic acids release. This study was conducted at ambient temperature in Malaysia. Approach: Two experiments were conducted: (1) Rice seeds undergoing germination were exposed to 0.5 mM CaCl2 … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 9,530 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Different Exogeneous Compounds on Biosorption of EndosulfanDeepika Dave, A. K. DikshitProblem statement: Organochlorine pesticide endosulfan is widely used as a replacement for DDT and dieldrin in many parts of the world. Presence of residual pesticides in the water, air and soil environment was confirmed since 1960s. Such Persistent Organic Pollutants (POPs) are of concern because of their long-term subtle effects on hormones, the immune system and reproduction. Therefore, it becomes … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 7,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcid-Base Buffering Properties of Five Legumes and Selected Food in vitroMaher M. Al-Dabbas, Khalid Al-Ismail, Ruba Abu Taleb, Salam IbrahimProblem statement: in vitro acid-Buffering Capacity (BC) values of 5% (dry matter) aqueous homogenized suspension of five legumes (broad bean, lentils, chickpea, kidney bean and lupine) and of selected antacid home preparations (cow's milk, almond, peanut, licorice, carob and lettuce stem) were investigated within and among samples from their respective initial pH until pH was decreased to 1.5. BC was … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 21 Jun 2010 · 9,739 accessesView PDFCite
Research ArticleOpen accessIn the abstractMetabolic Fingerprinting of Three Malaysian Ginger (Zingiber officinale Roscoe) Using Gas Chromatography-Mass SpectromertryH.J. Mahdi, R. Andayani, IshakProblem statement: There is a chemical variation among different ginger cultivars detected by previous studies including the volatile and non-volatile oleo-resins. In this study we try to determine whether these variations are related to a genetic factor rather than environmental or intrinsic factors. Approach: A comprehensive metabolic fingerprinting from the leaves of three micro-propagated ginger cultivars Bukit Tinggi, Tanjung Sepat … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,390 accessesView PDFCite
