Research ArticleOpen accessIn the abstractChemical Contaminants and Toxicity of Ganga River Sediment from Up and Down Stream Area at KanpurK. R. Beg, S. AliThe objective of this study was the sediment quality assessment of Ganga River at Kanpur city where effluents from tannery industries are discharged. Sediment samples from upstream and downstream area were collected and analyzed for trace metals and toxicity bioassay. Among various trace metals examined Cr in downstream sediment was 30-fold higher than in upstream sediment and its concentration was … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,601 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparison Effects of Sucrose and Date Palm Syrup on Somatic Embryogenesis of Date Palm (Phoenix dactylifera L )Abdullatif AlkhateebThe effect of different concentration of date palm syrup (2, 4, 6, 8 and 10%) and sucrose at concentration of 30 and 60 g/l in addition to the control (without carbon source) on the micro propagation of date palm "cv. Suckary" were investigated. The results indicated that date syrup was taken up from the media as shown by the increase … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 1 · 31 Mar 2008 · 7,982 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGamma Radiosensitivity Study on Chili (Capsicum annuum)Shairul Rizdiyandi Omar, Osumanu Haruna Ahmed, Shaharudin Saamin, Nik Muhamad Ab. MajidInduced mutation by gamma irradiation has been found to be a very useful technique for crop improvement. Apart from this, the proper use of induced mutation in plant breeding has become a profitable approach. This investigation was carried out to determine the LD50 and effect of gamma rays on germination, plant height, survival percentage, root length, root dry weight and … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 9,033 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGamma Radiosensitivity Study on Long Bean (Vigna sesquipedalis)Ellyfa Kon, Osumanu Haruna Ahmed, Shaharudin Saamin, Nik Muhamad Ab. MajidThis study was conducted to determine the LD50 and effect of gamma ray on germination percentage, plant height, survival percentage, root length, root dry weight and shoot dry weight of seedlings derived from seeds of long bean (Vigna sesquipedalis). Seeds of this crop were treated with 300, 400, 500, 600 and 800 Gy gamma rays at Malaysian Institute of Nuclear … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 8,596 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAllelopathic Potentialities of Gliricidia sepium and Acacia auriculiformis on the Germination and Seedling Vigour of Maize (Zea mays L.)M. B. OyunDecline in crop yield in cropping and agroforestry system in recent years has been attributed to allelopathic effects. Plants may favourably or adversely affect other plants through allelochemicals, which may be released directly or indirectly from live or dead plants. The objective of this study was to examine and quantify the nature of interference of leaf leachates of Gliricidia sepium … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 3 · 30 Sep 2006 · 9,790 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordBiocontrol of Damping off Disease in Brinjal (Solanum melongena) and Tomato (Solanum lycopersicum) by Arbuscular MycorrhizaMd. Raihan Talukder, Animesh Sarkar, Md. Harun Rashid, Md. Motaher HossainArbuscular Mycorrhiza (AM) fungi are recognized as bioprotectors of plants for their ability to enhance plant health and provide protection against pathogens. This study determines the ability of AM fungi (mixed AM inoculum of Glomus mosseae) to suppress the damping off disease of brinjal and tomato seedlings affected by the pathogenic fungi. This experiment consisted of two factors viz. AM … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 2 Jul 2024 · 5,010 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEffect of In Vitro Nitrogen Nutrition to Phalaenopsis deliciosa Seedling GrowthChieh Wean Choong, Chin Hao Lim, Zherui Xiong, Siew Mee ChoongIn a continuous effort to conserve Phalaenopsis species, the optimization of a previously designed defined medium was carried out to understand the effect of in vitro nitrogen nutrition on Phalaenopsis deliciosa Rchb.f. In order not to alter the nutrient balance, macronutrient level instead of solely Nitrogen (N) was adjusted. Seedlings were obtained from in vitro germination and randomly inoculated on … …OnLine Journal of Biological Sciences, Vol. 16, Issue 1 · 16 Dec 2015 · 7,824 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEFFECT OF COPPER SULPHATE AND COBALT CHLORIDE ON GROWTH OF THE IN VITRO CULTURE TISSUES FOR DATE PALM (PHOENIX DACTYLIFERA L.) CV. ASHGARAhmed Madi Waheed AL-MayahiThis study was carried out to investigate the effects of copper sulphate and cobalt chloride on propagation of date palm cv. Ashgar in vitro. The rate of callus proliferation was significantly higher in the medium supplemented with 2 µM copper sulphate and 2 µM cobalt chloride together (p<0.05). Addition of copper sulphate and Cobalt chloride to the medium was most … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 27 Nov 2013 · 8,456 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordControl of Phenolic Compound Secretion and Effect of Growth Regulators for Organ Formation from Musa spp. cv. Kanthali Floral Bud ExplantsSoubir Titov, Salil Kumar Bhowmik, Ajoy Mandal et al.The study was undertaken to examine banana cv. Kanthali floral bud apex as an alternative source material for in vitro propagation because huge number of explants die due to microbial contamination in case of shoot tip explants. Contamination free cultures were established by treating the floral bud explants with 0.1% HgCl2 for 6 min. This study found that inflorescence tissues … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 3 · 30 Sep 2006 · 7,742 accessesView PDF Cite
