Agarwood is a resinous wood produced by some members of plant family Thymelaeaceae under certain conditions. Agarwood is highly prized, but its formation requires a long-time process in nature. Therefore, various induction techniques have been explored to hasten the process. In this study, we induced agarwood in Gyrinops versteegii, one of the most abundant agarwood-producing trees in Indonesia. We used 12 trees and wounded four branches on each tree through an injection process. We used two strains of the endophytic fungi Fusarium solani isolated from Gorontalo and Jambi Provinces. After 3 months, the inoculated wood had an extensive resinous zone, when compared to wounded control wood. Gas chromatographic-mass spectrometric analysis of the inoculated samples revealed the presence of several sesquiterpenes characteristic of agarwood. These included alloaromadendrene, β-eudesmol and β-selinene as well as the chromone derivatives 2-(2-phenylethyl) chromen-4-one, 6-methoxy-2-(2-phenylethyl) chromen-4-one, and 6,7-dimethoxy-2-(2-phenylethyl) chromen-4-one. We conclude that this method successfully induced agarwood to form in a matter of months and could be used to enhance the success of agarwood cultivation.

枯萎镰刀菌可诱导紫斑杜鹃（Gilg。）Domke分支中沉香的形成

沉香是一种树脂状的木材，由某些植物百里香科成员在一定条件下生产。沉香树备受推崇，但其形成需要自然的长期过程。因此，已经探索了各种诱导技术以加速该过程。在这项研究中，我们在Gyrinops versteegii中引诱沉香，这是印度尼西亚产最丰富的沉香树之一。我们使用了12棵树，并通过注入过程使每棵树上的四个分支受伤。我们使用了两种内生真菌镰刀菌与哥伦打洛和占碑省隔离。与受伤的对照木材相比，接种后的木材在3个月后具有较宽的树脂区域。接种样品的气相色谱-质谱分析表明存在沉香木的几种倍半萜。这些化合物包括别芳金属环烯，β-eudesmol和β-selinene以及色酮衍生物2-（2-苯乙基）chromen-4-one，6-甲氧基-2-（2-苯基乙基）chromen-4-one和6， 7-二甲氧基-2-（2-苯乙基）铬-4--。我们得出的结论是，该方法可在数月内成功诱导沉香木形成，并可用于增强沉香木栽培的成功。
