Abstract

Cylindrocladium sp. is one of the diseases caused on leaf. Eucalyptus sp. is a plant that is used in the pulp industry. The objective of this study  to characterize the symptoms of foliar diseases and measure the desiases severity and diseases incidence on clone IND 65, IND 68 and IND 69. The infection of Cylindrocladium sp. was implemented with spraying method. Cylindrocladium sp., showed the symptoms was  redness brown spots and patches of grayish. Based on the diseases severity criteria three clones classifield as resistant clones. Based on the diseases incidence criteria of IND 65, IND 68  were classified as resistant and  IND 69 quite a bit resistant.Key words: Cylindrocladium sp., Eucalyptus sp.,  Infection test.

Abstract

Gubal of Agarwood is the infection of the microorganism and one of commonly used is Fusarium sp. The purpose of this research was to determine the presence of Fusarium sp consistency in agarwood (Aquilaria malaccencis Lamk.) which has been in the fungal inoculation.Sample which to used is stem which is taken away from Penungkiran Durin Jangah village, Pancur Batu. Isolation and identifying has been done in Forest Biotechnology laboraturium of Agriculture faculty University of Sumatera Utara, which is conducted from April – October 2013.  The result of this research showed that there are fifteen isolat of  fungi from the stem, that are five isolat Fusarim sp, two isolat Acremonium sp, two isolat Alternaria alternaria, one isolat Nigrospora sphaerica, two isolat Scopulariopsis sp, two isolat Cladosporium sp, one isolat Scytalidium lignicola, one isolat Mucor sp. Consistency Fusarium sp are superior on top stem and all of the part of the stem can be found Fusarium sp.Keywords: fungi, Agarwood, Reisolation, consistency

Abstract

Lignin is a polymer which has heterogen and complex structure and composed of alcohol coniferil, alcohol sinaphil, and alcohol kumaril so that hard to change. This research aimed to get white rot fungi isolat at eucalyptus wood and measure the ability of Lignin Peroksidase Enzim (LiP) of white rot fungi from eucalyptus wood as degrading lignin. Sample was get from Kesatuan Pengelolaan Hutan Lindung Tobasa area, North Sumatera. Type of white rot fungi originated from Eucalyptus grandis was Phanerochaete sp.1, Phanerochaete sp.2, and Exidia sp. Based on mend of LiP activity result, Exidia sp was the most potential for biopulping because it has highest activity point about 0,037 (U/MI). Key word : lignin peroksidase, eucalyptus wood, Bavendamm test, LiP test

Abstract

Cylindrocladium sp. is a pathogen cause disease that attack eucalyptus and  it  was the highest type of disease that attack eucalyptus in toba pulp lestari. Fungicide was used to eradicate and prevent the growth of pathogens. One of the fungicide which  used was systemic fungicide with active substance metiram 70 %. The purpose of this study was to measure the area, diameter, density of the spore ,and to characterize the hyphae form of Cylindrocladium sp after being treated metiram 70 % in vitro in different concentrations. Sample that used taken from cylindrocladium collection from previous research. The result of this study showed that the most efective concentration of fungicide treatment in inhibiting growth and development area of cylindocladium sp was treatment 2,0 mg/ml. In observation of spore density and hyphae structures of cylindrocladium sp, the fungicide that given was able to give tangible effect but in observation of relative inhibiton, concentration of fungicide gave intangible effect in providing inhibition to pathogen of cylindrocladium sp.Keywords: eucalyptus, cylindrocladium sp, fungicide, metiram, in vitro

Abstract

Lignin is a heterogeneous polymer and complex structure consisting of koniferil alcohol, sinaphil alcohol, and kumaril alcohol making it difficult to overhauled. The complex structure of lignin with high molecular weight and insoluble in water makes lignin difficult to degrade. The purpose of this research is to get white rot fungi in biopulping process by measuring the activity of Lignin Peroxidase Enzime (LiP) at white rot fungi which is obtained. The sample of rotten eucalyptus wood taken from Taman Hutan Raya (Tahura) Berastagi. Bavendamm test have found three genus of fungi which are Phanerochaete sp. 1, Phanerochaete sp. 2, Trametes sp. The highest activity of lignin peroxidase enzyme was produced by Phanerochaete sp. 2. Key words: Eucalyptus wood, White rot fungi, Bavendamm test, lignin peroxidase enzyme

Abstract

Phaeophleospora sp is one of diseases which attack eucalyptus plant particulaily on eucalyptus nursery. This disease has been spread almost in the whole world. North Sumatera Control of the disease itself still use a fungicide and one of them is the fungicide active ingredient Metiram 70%. The purpose of this reseaech is to know the response of Phaeophleospora with fungicide Metiram substance 70% treatment with 0,4 ,0,8 ,1,2 and 1,6 mg/ml as concentrate. Response which measured was colony growth (wide, diameter, spora density, and change that happened to hifa). Research conducted at Forest Biothechnology Laboratory and Pest Plant Pathology Laboratory, Agriculture Faculty, University of North Sumatera. Used general linear non factorial with five times repetitions.        The 70% metiram treatment in 0,4, 0,8, 1,2 and 1,6 mg/ml  significant to the growth (wide, diameter, barriers relative and spore density) and also caused swelling on hyphae and change of form, tekstur and the color of colony Phaeophleospora sp. in vitro.Keywords : Phaeophleospora sp, Response In Vitro, Metiram 70%
