Abstract

A study about gastrointestinal helminths of Mesocricetus auratus (Waterhause, 1839) in Padang, West Sumatera was conducted from March to July 2013. This study was aimed to identify species of gastrointestinal helminths and to determine the prevalence of gastrointestinal helminths of M. auratus in Padang. Sampling was conducted by using Purposive methods. Those samples were examined by using direct observation, floating-centrifuge and sedimentation method. A total of four helminths species that belonging to two phylums and four orders was collected. The obtained helminths were Hymenolepis nana Siebold, 1852 (Cyclophyllidea), Syphacia obvelata Rudolphi, 1802 (Ascaridida), Sp. 1 (Strongylida), and Sp. 2 (Enoplida). The prevalence of Syphacia obvelata, Hymenolepis nana, Sp. 1 and Sp. 2 were 57,1%, 50%, 17,1% and 17,1%, respectively.

Abstract

One of prospective banana collections at Indonesian Tropical Fruits Research Institute is Ambon kuning (Gros michel) origins from Jambi. The aim of the study was to find out the response of Ambon kuning to some Vegetative Compatibility Groups (VCGs) of Fusarium oxysporum f. sp. cubense. The research was conducted from November 2012 to February 2013 in the laboratory of plant disease and the screen house of Indonesian Tropical Fruits Research Institute of Solok. The treatment used a Randomized Block Design (RBD) with 6 treatments and 4 replications, each treatment consisted of 5 plants. Treatments were 6 isolates of Foc VCGs 01213/16, 0121, 01219, 0123, 0124/5, 0120/15, those were the Indonesian Tropical Fruits Research Institutes collection. The parameters observed were percentage of plants infected, the incubation period, index of diseases severity on leaves and corm. Data was analyzed by analysis of variance. The results showed that Ambon kuning (Gros Michelcv) was resistant to Foc VCG 01219 and VCG 0120, moderately resistant to Foc VCG 0123, susceptible to Foc VCG 0121 and VCG 0124/5, and highly susceptible to Foc VCG 01213/16 Keywords: banana, resistance variety, Fusarium oxysporum f. sp. cubense, Vegetative Compatibility Group (VCG)

Abstract

The research about compotition and structure community of zooplankton in lake Singkarak has been done from March 2013 until May 2013. This study used purposive method and zooplankton sampling was done by using vertical filtering from 10 stations. The results shown that there were 16 species zooplankton with Crustacea (8 species), Protozoa (3 species) and Rotifera (5 species). Average population density of zooplankton were 32.43 ind./l with varying type on each station. Diversity index were 0.79-1.52 and highest was found at station II and IX (H’=1.73) and lowest was found at station IV (H’=1.73). Equitability index was 0.32-0.91% higest was found at station X (E=0.91) and lowest was found at station IV (E=0.32). Similarity index was 31.25-76.92%. Based on the diversity index of zooplankton show that the community was relatively stable. Key words : Singkarak, Zooplankton, Structure, Composition, Community

Abstract

An investigation on the changes of individual number and distribution pattern of Schismatoglottis lancifolia Hall. et Englar at permanent forest plots in Bukit Pinang-Pinang has been carried out from September 2012 to December 2012. The results showed that populations of Schismatoglottis lancifolia was 51.63% decreased when compared to the previous observations in 1985. The distribution pattern of the species was clumped (Morishita Index : 3.2) that was similar pattern reported in 1985. Distribution pattern was influenced by relative light intensity due to topography variations. Keywords: Bukit Pinang-pinang, distribution population, Schismatoglottis lancifolia.

Abstract

A study on growth of turmeric (Curcuma zedoaria Rosc.) inoculated with Arbuscular Mycorrhizzal Fungi (AMF) isolated from the rhizosphere of Situngkek (Hornstedtia scyphifera Steud.) was done from March to August 2013 in the wire house and in Plant Physiology Laboratory, Department of Biology, Faculty of Natural Sciences, Andalas University. The aim of this study was to determine the growth of white turmeric inoculated with several doses of AMF. The experiment used Completely Randomized Design (CRD) with five treatments, control (A) and four replications. The inoculation doses were 10 g / Plant AMF (B), 20 g / plant AMF (C), 30 g / Plant AMF (D), 40 g / Plant AMF (E), 50 g / Plant AMF (F). The results showed that AMF inoculation gave no significant effect on plant height, number of leaf, leaf width and dry weight of turmeric. The highest root infection was 30 gr/plant (74.83 %). Generally, turmeric plant have a dependency on FMA inoculation with less and sufficient criteria of Habte and Manjunath. Keyword: Curcuma zedoaria, Mycorrhizal, Growth.

Abstract

An experiment of giving mulch of rice straw (Oryza sativa) on weeds and crop production soybeans (Glycine max (L.) Merr) has been carried out at the Laboratory of Plant Ecology, Andalas University, Padang from June to September 2013. The purpose of this study was to determine and define how mulch of rice straw suppress weed growth and increase the production of soybeans. This experiment used a Completely Randomized Design with five treatments and five replications. The result showed that rice straw mulching of 300g/10kg can suppressed the growth of weeds, and rice straw mulching of 500g/10kg could increase soybean production. All treatments showed significantly influence on the increase weight of soybeans product. Keyword: mulch, rice straw, soybean, weeds
