Pengaruh Konsentrasi Giberelin (GA3) terhadap Pertumbuhan Kailan (Brassica oleracea L. Var alboglabra) pada Berbagai Media Tanam dengan Hidroponik Wick System
Get PDFEffect of giberelin (GA3) concentration on growth and yield of Chinese kale (Brassica oleracea L. Var alboglabra) in various medium using hydroponic wick system . This research conducted from April until July 2016 in Wire House and Plant Physiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Science, Andalas University. The purposes of this research were to obtain GA3 concentration and planting medium that accelerate growth and yield of Chinese kale and determine the interaction between GA3 and planting medium to the gowth and yield of Chinese kale planted using hydroponics wick system. This research used Completely Randomized Design (CRD) in factorial with three replications, as the first factor were concentration of GA3 (0 ppm, 20 ppm, 40 ppm and 60 ppm) and the second factor were medium (zeolite, sand, husk and sawdust). The best result in accelerated the growth of Chinese kale was the treatment at the concentration of 60 ppm GA3 and zeolite was suitable medium to Chinese kale growth. This research found the interaction between GA3 and medium on the length of the roots Chinese kale used hydroponic wick system

Get PDFResearch on The Presence of Natural Microflora in Fermentation of Green Apples Cider Vinegar (Malus sylvestris Mill.) Cultivars Granny Smith was conducted from February to June 2014 at Microbiology Research Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Andalas University, Padang. The purpose of the research were to determine the Presence of the natural microflora (yeasts and bacteria) in fermentation of a Granny Smith apple cider vinegar and to determine the character of apple cider vinegar in terms of pH value dan sugar content. The results showed that the fermentation of apple cider vinegar was the Presence of the natural microflora (yeast as much as 1.8 x 106 cfu/ml and bacteria as much as 3.4 x 106 cfu/ml) and obtained with apple cider vinegar acid concentration (pH 3.13) with a residual sugar content (1.5% Brix) after 14 days of acetic acid fermentation.Keywords: Â Â Â Â Â Natural Microflora, Granny Smith Apples, Apple Cider Vinega
Respon Pertumbuhan Nodus Artemisia vulgaris L pada Medium Murashige-Skoog dengan Penambahan Beberapa Zat Pengatur Tumbuh Secara In Vitro
Get PDFArtemesia vulgaris L produce artemisinin which is effective against resistant strains of Plasmodium falciparum, the malarial parasite. The study about growth responses of Artemesia vulgaris L in Murashige-Skoog (MS) medium supplemented with several growth regulators had been done from September to November 2014 at the Laboratory of Plant Phisiology and Tissue Culture, Department of Biology, Faculty of Mathematic and Natural Science, Andalas University. The aims of the study was to know the responses of node explants of Artemesia vulgaris L supplemented with several plant growth regulators for the effective technique of propagation. The study used Completely Randomized Design with four treatments and six replications. Node from in vitro growth were treated with three different kind of growth regulator (0.3 ppm BAP, 0.5 ppm NAA, 0.3 ppm GA3) in MS medium. The result showed that 0.5 ppm NAA was the best growth regulators formed callus, bud, and root of Artemesia vulgaris L.Keywords: Artemesia vulgaris L, plant growths regulator, in vitr
Analisis Morfologi Granula Pati dan Kristal Pada Beberapa Jenis Talas
Get PDFThe study of comparative characters of starch grain and crystal morphologically had been done among five species of taro from January until April 2013 in Plant Structure and Development Laboratory, Department of Biology, Faculty of Mathematics and Natural Science, Andalas University. The corm of taro species were analyzed the character of shape and size by using fresh preparate. The result showed that X. sagittifolium and X. violaceum have circular starch grain, while C. esculenta cv. 1, C. esculenta cv. 2, C. esculenta cv. 3 have ellip starch grain. The shape of calcium oxalate crystals found is a bundle of raphide, individual raphide and druse. The all species of taro have individual raphide. C. esculenta cv. 1 and C. esculenta cv. 3 have raphides and druse crystal.

Pengaruh Inokulasi Gabungan Beberapa Vegetative Compatibility Group Isolat Fusarium oxysporum f.sp.cubense Pada Pisang Ambon hijau
Get PDFThe aim of this study was to determine level of virulency of several Vegetative Compatibility Group (VCG) of Fusarium oxysporum f. sp. cubense (Foc) isolates against cv Ambon hijau. The study was conducted at the laboratory of plant diseases and screen house of Solok Tropical Fruit Research Institute from August 2012 to February 2013.The experiment was arranged in randomized block design with seven treatments and four replications, each treatment consisted of fiveplants. The treatments were the mixture of isolates FocVCG 01213/16, 0121, and 0124/5 andthe single. The results revealed that several VCG isolates of Foc grouped in race 1 and 4 inoculated in single or mixture caused the highest disease incidence with the percentage of wilt was 100%. The fastest incubation period of disease on cv Ambon hijau caused by isolate VCG 01213/16 (5.95days), followed by VCG (11.35 to 12 days), single isolate of VCG 0121 (13.15 days) and VCG 0124/5 (17.45 days).

Identifikasi Koleksi Jamur dari Cangkang dan Pasir Sarang Telur Penyu Lekang (Lepidochelys olivacea L.) di Penangkaran Pariaman
Get PDFThe district of Pariaman has a conservation site for sea turtles, including olive ridley (Lepidochelys olivacea L.). Several reports have stated that fungus infect egg of the turtles and caused the failure of hatching. However, there is no study on this site yet. The aim of this study was to identify fungus on turtle's egg, hatched and inhatched nest sand. Collection and identification were conducted from December 2012 until June 2013 in turtles’ breeding in Pariaman and Microbiology Laboratory of Biology Department of Mathematic and Natural Sience, Andalas University. Result showed that Fusarium sp. 1, Fusarium sp. 2, Fusarium sp. 3, Fusarium sp. 4, Fusarium sp. 5, Fusarium sp. 6, Fusarium sp. 7 dominated among identified fungus, other were Aspergillus sp. 1 and Trichoderma sp. 1 and than there was no fungus found on hatched egg.
