Research ArticleOpen accessIn the abstractINCREASED NUTRIENT SOLUTION CONCENTRATION DURING EARLY FRUIT DEVELOPMENT STAGES ENHANCES PUNGENCY AND PHENYLALANINE AMMONIA-LYASE ACTIVITY IN HOT CHILI (CAPSICUM ANNUUM L.)Parichat Dittakit, Thammasak ThongketThe effect of increased nutrient concentration during different fruit development stages on the yield, pun-gency and PAL enzyme activity in hot chili cv. ’Super hot’ was studied during August 2009-January 2010. The seedlings were planted in plastic containers containing 20 L of coconut-coir-dust substrate placed inside a plastic-roofed net house and received Resh’s Tropical Dry Summer nutrient solution at a … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 27 Dec 2013 · 7,492 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessment of Heavy Metals Uptake and Translocation by Aquilaria malaccensis Planted in Soils Containing Sewage SludgeKeeren Sundara Rajoo, Arifin Abdu, Hazandy Abdul-Hamid et al.Increase in human population has resulted in an enormous growth in the volume of wastewater. The conventional methods of sewage sludge disposal, that is the by-product of wastewater treatment, are costly and not environment-friendly. An ideal way for sewage sludge management is by using it as a soil amendment in agricultural land due to sewage sludge’s high organic matter content. … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,079 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHeavy Metal Uptake and Translocation by Dipterocarpus verrucosus from Sewage Sludge Contaminated SoilKeeren Sundara Rajoo, Arifin Abdu, Daljit Karam Singh et al.Sewage sludge or biosolids is the solid waste that has been left after wastewater is treated in a domestic wastewater treatment facility. The most common way of sludge disposal is to dispose it on the land, sea or air (incineration). However, these methods are not environment-friendly, costly and time consuming that requires expertise and knowledge. An ideal way to manage … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 10 Jul 2013 · 7,819 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTransformation of Lesquerella Fendleri with the New Binary Vector pGPro4-35SGrace Q. Chen, Roger Thilmony, Jiann-Tsyh LinProblem statement: Crop genetic engineering requires the use of various promoters to control the expression of introduced transgenes. Some of the binary vectors currently available for promoter characterization in dicotyledonous plants have pitfalls due to their construction, such as containing a selectable marker cassette with enhancer sequences that can potentially interfere with the expression specificity of nearby promoters. Also, many … …OnLine Journal of Biological Sciences, Vol. 11, Issue 3 · 19 Jan 2012 · 7,425 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiocontrol of Soil Fungi in Tomato with Microencapsulates Containing Bacillus subtilisMarcela Hernàndez-Suàrez, Francisco Daniel Hernàndez-Castillo, Gabriel Gallegos-Morales et al.Problem Statement: An option to reduce pollution by synthetic agro-chemical in root plant disease management is the use of antagonist rhizobacteria belonging to Bacillus genus, because their inhibitory properties, stimulation of plant growth and crop yield increase. Approach: This study was carried out in order to evaluate if Bacillus subtilis strains could play an antagonists role of plant pathogens and … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 8,925 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of a Dual-Purpose Chemical Applicator for Paddy FieldsMohammed Shu’aibu Abubakar, Desa Ahmad, Othman Jamarei et al.Problem statement: One of the major problems of rice production is the shortage of labor resulting from migration from rural to urban areas, making it very difficult to meet peak demands for paddy production. In most developing countries of Southeast Asia, agricultural mechanization of paddy field operation is mostly carried out using conventional machines. For example in rice production powerintensive … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,542 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUptake of Heavy Metals by Jatropha curcas L. Planted in Soils Containing Sewage SludgeParisa Ahmadpour, Azmi Mat Nawi, Arifin Abdu et al.Problem statement: The chemical pollution of soil has become a major source of concern and has posed serious health problems within the last few years in many developed nations. A variety of organic and inorganic pollutants, including heavy metals, are being mixed in with the cultivated soil and water. Sewage sludge was one of the major sources of enrichment of … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 10,265 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Effects of Drought and Salt Stress on Germination and Seedling Growth of Pennisetum divisum (Gmel.) Henr.Wafa’a A. Al-TaisanProblem statement: Water stress due to drought and salinity is probably the most significant abiotic factor limiting plant and also crop growth and development. Salinity and drought stresses are physiologically related, because both induce osmotic stress and most of the metabolic responses of the affected plants are similar to some extent. Water deficit affects the germination of seed and the … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 27,311 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSalicylic Acid Protects Nitrate Reductase Activity, Growth and Proline in Amaranth and Tomato Plants during Water DeficitC. E. Umebese, T. O. Olatimilehin, T. A. OgunsusiProblem statement: Seedlings of Amaranthus hybridus cv. NHAC-3 (large green, amaranth) and Lycopersicum esculentum cv. Roma (tomato) were subjected to 7 days water stress at Early Vegetative (EV), Late Vegetative (LV), Early Flowering (EF) and Late Flowering (LF) stages of growth to study the impact on leaf water potential (ψw), Nitrate Reductase Activity (NRA), growth (plant height, shoot and root … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 9,565 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnhanced Survival and Nodule Occupancy of Pigeon pea Nodulating Rhizobium sp. ST1 expressing fegA Gene of Bradyrhizobium japonicum 61A152Falguni R. Joshi, Dhwani K. Desai, G. Archana, Anjana J. DesaiProblem statement: Rhizobial isolates belonging to genera (Rhizobium sp. and Mesorhizobium sp.) in our laboratory produced only catecholate type of siderophores. Although FhuA and FegA (ferrichrome receptors) homologs were found to be present in the sequenced genomes of few rhizobia (e.g., 1 in R. etli and 2 in Mesorhizobium sp. BNC1), laboratory isolates of the corresponding genera failed to utilize … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 30 Jun 2009 · 7,865 accessesView PDF Cite
