Abstract

Agarwood (Gaharu) is an important non-timber forest products and has high economic value. The agarwood is the final product obtained from species A.malaccensis Lamk as raw material for the pharmaceitical and cosmetic industries. Increasing of the gaharu collection and international market circulation have resulted in the decline of the gaharu. The presence of gaharu in nature endangered triggers to do multiplication  aloes one with tissue culture technique. This research aims to determine the response of seed explants A.malaccensis and determine the concentration of the best growth regulator. This research used a Complete Random Design (RAL) with Growth  Regulator IAA in any concentrates with agarwood seed explants. The results showed that giving of IAA growth regulator that responds to the growing sprouts. Treatment concentration of IAA significant to the time sprouts appear but not significant on the appearance of sprouts, number of leaves and sprouts length. Emerging sprouts fastest time occurred in the treatment of 6 ppm IAA 9 days after planting. Keyword: Agarwood, Tissue Culture, Growth Regulator

Abstract

Agarwood is non-wood forest product with high number of economic because the wood has many benefits. The presence of gaharu in nature is endangered because of illegal logging and for development of agarwood needed seed quality supplying, one with tissue culture. This study aims to determine the response of seed explants A. malaccensis and determine the concentration of the best NAA and IBA for induction of callus. This research use Complete Random Design (RAL) with 2 Growth  Regulator NAA and IBA in any concentrates with agarwood seed explants. Results showed that callus was obtained as response of  agarwood seed explants with NAA and IBA and the concentrate that’s have real an effect on to determine the time of callus appear with best concentrate was NAA 2 ppm dan IBA 2 ppm. Callus appear dominated by olive green and green brown color, meanwhile tekstur of callus dominated by compact node. Keywords: Agarwood, Callus, NAA, IBA, in vitro

Abstract

Eucalyptus is a species that widely used in pulping industry. Phaeophleospora is one of the pathogens that attack the leaves of young Eucalyptus plant. The purposes of this research were to characterize the leaf disease symptoms and to measure disease severity and disease incidence caused by Phaeophleospora spp. on two-month-old IND 47, IND 61, dan IND 66 Eucalyptus grandis x Eucalyptus urophylla hybrid clones. Inoculation was implemented with spray method. The leaves symptoms caused by Phaeophleospora showed the same symptoms on clones IND 47, IND 61, and IND 66. The early symptoms were the yellow dots on the upperside of the leaves and then developed into spots. The advanced symptoms were reddish spots on the upperside of the leaves and black spores on the underside of the leaves. Three clones were classified as resistant in disease severity measurement, meanwhile in disease incidence measurement, three clones were classified as moderately resistant. Keywords : Phaeophleospora, infection test, symptoms, resistant

Abstract

Fertilizationis a means or method used for fertilizer through the leaves and plant part slain.The purpose of this study was to determine the frequency of fertilization and foliar fertilizer concentration is best for seedling growth aloes (A. malaccensisLamk.). The samples used were aloe plant seeds that have been aged 3 months were taken from CV. Earth Partners II, Land of a Thousand Village, city Binjai, North Sumatra. Nursery heldon the 4th floor of buildings Forestry Faculty of Agriculture, University of North Sumatra, which was conducted in November-January2013. The results showed that the frequency of the treatment of liquid foliar fertilizer application significantly affected the height and number of leaves.Treatment of liquid foliar fertilizer concentration significantly affected the number of leaves.The interaction frequency and concentration of liquid foliar fertilizer application significantly affected height and number of leaves.   Keywords: fertilization, agarwood, frequency, concentration

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

Daun Sang is an endemic species that can be found in Gunung Leuser National Park and Bukit Tiga Puluh National Park. This palm is thought to have associations with other palm. Where around Daun Sang grow there are palm types Lipai (Licuala spinosa), but not always around Lipai grow Daun Sang are. Daun Sang need shade to grow because these palm is sensitive to the sunlight. This study  aimed to analyze the association  of daun sang by some kind of palm that grows around in order to conservation and optimize the cultivation of the daun sang. The method used is a descriptive method with observation of the Daun Sang number and some kind of of palms around it done intentionally (purposive sampling). The method is performed by making 2 plot observations, each size is 100m × 100m,  then divided by making the sample plots of 20m × 20m. Observed data were processed using 2 x 2 contingency table, and then calculated by the chi-square test formulations and Jaccard index to calculate the extent of the association. three species of palm found in the study site there are pinanga speciosa, tetradactylus and Plectomiopsis Calamus sp. The results showed that daun sang are not associated with Pinanga speciosa. Association occurs between daun sang with the Calamus tetradactylus and daun sang with Plectomiopsis sp. The highest level of association occurs in Daun Sang and Calamus tetradactylus with maximum association index value of 1. The level of association between Daun Sang with Plectomiopsis sp. approaching the maximum value of the association index in 0.84.Key word : Daun Sang (Johannesteijsmania altifrons), Association Analysis, Ressort Sei Betung
