UJI INFEKTIVITAS DUA INOKULAN FUSARIUM SPP. PADA TANAMAN PENGHASIL GAHARU (AQUILARIA MALACCENSIS LAMK.)
Daftar Isi:
- Agarwood is a resin produced by the Aquilaria malaccensis tree, agarwood is formed due to infection of A.malaccensis trees by microbes, it can occur naturally or artificially. The formation of agarwood in nature occurs through the opening of nature with a limited amount, so the process of formation of agarwood is very slow and requires a very long time. Therefore, a lot of manipulations is done to accelerate the formation of agarwood, one of which is by inoculating Fusarium spp. This study aims to determine the infectivity of some Fusarium spp. against the formation of agarwood. This research was conducted at the Phytopathology Laboratory of Plant Protection department, Sriwijaya University and the gaharu garden owned by Mr. Kamaludin in Gandus, Palembang, South Sumatra in October-December 2019. The research was conducted using the RBD method with 3 treatments repeated 10 times. These treatments were kontrol (P1), Fusarium tomato inoculants (P2) and corn Fusarium inoculants (P3). Observations are made once every 1 month after application. Application of several Fusarium inoculants spp. affect the area of spots and discoloration in A. malaccensis trees. Spots on the kontrol area were 1.04 cm2 in the first month and 1.13 cm2 in the second month. Spots area in the Fusarium tomato treatment in the first month was 1.38 cm2 and in the second month it was 1.51 cm2. The area of spotting in the Fusarium Corn inoculant treatment in the first month was 1.54 cm2 and in the second month it became 1.69 cm2. Color changes in the borehole also occur due to the application of Fusarium inoculants. In the treatment of color kontrol to brownish white, in the Fusarium inoculant treatment the tomato color changed to brown and in the Fusarium inoculant treatment the corn became blackish brown. Fusarium inoculant infection spp. managed to show the initial symptoms of the success of the formation of agarwood is characterized by increased extent of spotting of infection and a change in color at the point of infection
