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

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
