Abstract

ITONAMY BORU TONGA. Effect of Plant Growth Regulator 2,4-D on  Seed Explant A. malaccensis in vitro. Guided by Dr. Ir.Edy Batara Muyla Siregar Ms. And Nelly Anna S. Hut. Msi. Aquilaria malaccensis Lamk. is one of the tree forest that are continuosly exploited. Currently, the Indonesian export of the agarwood was decreasing because its population was endangered by excessive logging. Agarwood propagation need technology for reproduction of agarwood multiplication. Research was undertaken to determine effect of plant growth regulator 2,4-D on seed explant A. malaccensisi in vitro has been performed. This research had purpose to determine  response of seed explant of gaharu by giving different cosentration 2,4-D and to measure growth and developtment result of seed explant of gaharu. This research used a complete Randomized Non Factorial Design with using MS as basic media by added 2 ppm of BAP. The treatment consisted of 2,4-D 2 ppm, 4 ppm, 6 ppm and 8 ppm. Observation made explants fourty two days after planting. The parameter observed were the emergence of callus, callus color and  texture of the callus.  The result showed that callus was obtained as response of A. malaccensis seed explant with 2,4 D and BAP. The concentration 2,4-D 2 ppm showed the best result for the emergence of callus. Callus color is dominate by white and a bit yellow or scoring 4, and the callus texture is dominate by compact callus and compact with node. Keywords: Effect, 2,4- D, in vitro, A. malaccensis Lamk.

Abstract

Eucalyptus spp is a fast-growing plant species that have economic value and multifunction primarily developed as a raw material for the pulp extensively. Weeds is one factor that can inhibit the growth of Eucalyptus spp.This study aims to inventory the types of weeds present in young Eucalyptus spp. and know the composition and dominance of the types of weeds that were needed in the management of industrial plantations of Eucalyptus spp. The research was conducted at PT. Toba Pulp Lestari, Tbk Aek Nauli sector in March-June 2011. The results showed that the diversity of weed found in Eucalyptus spp plantation consisted of 15 families and 39 species were relatively similar and were dominated by the family Rubiaceae, Asteraceae, Melastomataceae, and Poaceae. Borreria sp, Clidemia Hirta, Commelina difusa and Imperata cylindrica was  an important and very dominant weed in all young Eucalyptus spp planting area. Keywords: Inventory, Eucalyptus spp, weeds.

Abstract

Lignin is a natural polymer and an important compound of plant cell wall constituent. The research objective to get white rot wood in the Rotten Karet Wood, measure the activity of lignin peroxidase at White Rot Fungi, and know the potential of White Rot Fungi for biopulping.  The samples taken at Karet land in Arboretum USU. The Bavendamm and lignolitic enzyme activities test found three species of fungus that came from genus Phanerochaete sp1, Phanerochaete sp2, dan Exidia sp. The highest activity of lignin peroxidase was produced by Phanerochaete sp2 isolate by the value of 0,466 U/ml. Key word : karet wood, white rot fungi, lignin peroxidase, bavendamm test.

Abstract

Lignin is a natural compound of plant that has a function for plant cell wall constituent. In pulp industries, lignin is a compound which is hard to be degradad. The purpose of this research is to get white rot fungi in the rotten pine wood, to determine potential of white rot fungi in biopulping process which obtained by measuring the activity of enzyme Lignin Peroxidase (LiP) at white rot fumgi which is obtain from the rotten pine wood. The sample of the rotten pine wood taken from Taman Hutan Raya (Tahura) Berastagi. Bavendamm and ligninolitic enzyme activities test have found three spesies fungi which are in genus Trametes sp.1, Trametes sp.2, and Phanerochaete sp. The highest activity of enzyme lignin peroxidase was produced by Trametes sp.1 fungi by the value is 1,541 U/ml. Key word: White rot fungi, Pine wood, Bavendamm test, enzyme lignin peroxidase.

Abstract

Cylindrocladium sp. is one of the pathogens trigger dangerous diseases that blight the eucalyptus plant. Fungi is one of the pathogens that attack the breeding ground and nursery eucalyptus in various parts of the world, including Indonesia. Efforts to control its spread by means of direct control is by the use of fungicides. Fungicides are used in this research is a contact fungicide mancozeb 80% active ingredient. The study aims to measure the growth of the colonies, the relative constraints, the density of spores and hyphae shape changes Cylindrocladium sp. after treated with 0, 0.4, 0.8, 1.2 and 1.6 mg / ml. The sample used was taken from the collection of fungi in Forestry Biotechnology Laboratory. The research was conducted in February 2015 until April 2015 at the Biotechnology Laboratory of Forestry, Department of Forestry and in the Laboratory of Disease Study Program Plant Pests and Diseases, Faculty of Agriculture, University of North Sumatra. Results of the study are significant response at each concentration fungicide mancozeb. Response significant effect starting from the 12th day until the 16th day of observation. The response of the real effect is diameter growth, barriers relative density of spores. Besides treatment causes swelling and breakdown of the structure of hyphae. Key Words: Response, In Vitro, Cylindrocladium sp., Fungicide Mancozeb 80%  WP

Abstract

Eucalyptus leaf sp. is a fast-growing plant species as raw material pulp industry at large.  At the time of this plant breeding susceptible to deases. One is a deseases caused by a fungal leaf Cylindrocladium sp. The objectives of this research aims to characterize the symptoms of foliar diseases and measure the intensity and widespread attacks caused by Cylindrocladium sp. the clone IND 47, IND 61 and IND 66. Infection done bye spraying inoculants fungi in this experiment used three clone of plant E. grandis x E. urophylla age of two month from the observation of the symptoms of the diseases symptoms appear, calculated intensity and widespread attacks. The results showed symptoms on leaves caused by infection Cylindrocladium sp. the three clones have the same symptoms are red spots on the leaf surface and then develop into red-brown spots. In measuring the intensity of the attacks and extensive third attack resisten clones are clones Keywords: Cylindrocladium sp., Hybrid Clones of Eucalyptus, Infection Test

Abstract

One of the diseases that attack in the Eucalyptus nursery is Cylindrocladium causing Cylindrocladium foliar spots and foliar blight disease. Cylindrocladium found in eucalyptus nurseries PT Toba Pulp Lestari . According Sembiring (2008) research, Cylindrocladium fungal virulence is the highest of the pathogen found in nurseries . This study aimed to characterize the symptoms of foliar diseases caused by Cylindrocladium on the derived crosses hybrid clones of the type of Eucalyptus, Eucalyptus grandis x Eucalyptus pellita and measure the level of the intensity of the attack, the extent of the attack, as well as the reaction of plants (resistance) of the hybrid clones of Eucalyptus grandis x E. pellita. Infection is done by spraying inoculants fungi on leaves of three clones seedling of E. grandis x E. pellita age of two months, Clone IND 32, Clone IND 33 and Clone IND 45. The symptoms of infection that appearon leaves then reisolated by the method of Koch's postulates. Symptoms caused by infection Cylindrocladium on E. grandis x E. pellita leaves is blight disease. Symptoms begin with yellowish brown spots and will be widened (necrotic) then continue in severe leaf tissue death. The  incubation period for infection of Cylindrocladium faster seen in clone IND 45, but the pace of progress has been slow. In clone IND 32 and IND 33 the incubation period of infection longer appear, but the pace of progress are most intense. Cylindrocladium infection does not affect the growth (resistance) of E. grandis x E. pellita seed age of two months. Key Words: Eucalyptus sp, Cylindrocladium sp, Infection Test, Leave Blight Disease
