Identification of Morphological Characters of Aquilaria microcarpa in the Interaction with Fusarium solani

Abstract

The principal mechanism acted in the formation of aloes on gaharu trees has not been well understood. The formation was thought to be one part of plant defense systems. The response of plants during interactions with pathogens is to react by synthesizing variety of toxic molecules both protein and non-protein molecules serving as protection against pathogens. Changes occurring in plants as a result of damage or stress were a response of induction causes. This study aimed to determine the effect of induction of the Fusarium spp inoculant (after 3 years) on the phenotypes of Aquilaria microcarpa. Based on observations and measurements of the general characters, results indicated that the inoculated Aquilaria microcarpa plants in Carita Banten had significant mean values higher than that of the un-noculated plants. In the inoculated plants, morphological character of total height was highly correlated with stems robustness, height of branch-free, diameter and volume of branch free.
