This research has been conducted at the Experimental Farm of Agricultural Faculty of Andalas University, two districts in West Sumatera (Lima Puluh Kota and Agam) and the Laboratory of the Department of Agronomy and Horticulture Agricultural Faculty, Bogor. The purpose of this study was to determine the genetic diversity of the ramie plants collection Experimental Farm, Agricultural Faculty of Andalas University and exploration at two districts in West Sumatera. This research was conducted by molecular characterization, using RAPD markers (Random Amplified Polymorphic DNA) with 5 primers (OPF 4, OPF5, OPH7, OPX2, and OPX 17). The samples used were 4 clones of ramie plants (Padang 3, Ramindo, Matur and Situjuah) with 3 replications. Fragments were sized with reference to the size markers and scored (present/absent). The similarity coefficients calculated and dendograms produced using NTSYS software (version 2.02). From the results of the study the results of the similarity level coefficient were 0.56-0.78, and formed 2 large groups (I, II). M1 and M2 clones are in group I, while in groups II (IIa and IIb). Group IIa (R1, R2, R3, P3, M1) and Group IIb (S1, S2, S3, P1).
<p>Flax/jute is natural fiber plants that that produce fiber from the bark. Ramie fiber has a better quality than the others natural fiber, so it can meet fiber the increase needs cultivar with the best chemical composition of fiber. The aim of this study was to detect the chemical composition of fiber in several clones of ramie from West Sumatera. The study was conducted on December 2018 at the Laboratory of Technology Agriculture Product Andalas University for analyzed the content of chemical composition (water, ash, holocellulose, cellulose, hemicellulose, and lignin). The result of this study showed that the highest level of water content, ash, hemicellulose, and lignin were found in Situjuah clones those are 40.43, 6.74, 14.39, and 9.98% respectively. Whereas for the highest level of holocellulose and cellulose contents were in Ramindo 1 clone those were 70.23 and 58.46% respectively.</p>
The purpose of this study was to collect and determine the morphological and molecular character of the ramies in West Sumatra. This study was conducted in May-October 2018 Experimental Farm, Faculty of Agriculture, University of Andalas Padang. This a ctivity also used the clone Padang 3 and Ramindo 1 as a comparison. The results of this study indicated that the ramie plant could grow to a height of 1058 meters above sea level to the point where the coordinates 0 ° 15'30 "South Latitude and 100 ° 15'45" east longitude. Ramie highest Situjuah accession 150.03 cm and the lowest at 91.7 cm Matur accession. The longest and widest leaf observations contained in the accession Situjuah while the shortest and smallest obtained at Matur accession. On accession Situjuah, Matur, and clones Ramindo 1 had male and female flowers but clone Padang 3 only had female flowers. Harvesting fastest in clones Ramindo 1 was 123 days and the longest in clones Padang 3 was 133 days. The numbers of banding pattern resulting from PCR amplification were 74 tapes (68 a polymorphic bands while the rest was the number of monomorphic bands).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
