Characteristic of stem rot diseases caused by Ceratocystis sp. on Acacia decurrens and its status in Gunung Merapi National Park, Yogyakarta
Mount Merapi National Park (TNGM) has been dominated by Acacia decurrens after the eruption in 2010. Almost 80% of A. decurrens trees showed stem rot diseases caused by Ceratocystis sp. which may associate with stem wound induced by ambrosia beetle and other physical injuries. The research objective...

| description | Mount Merapi National Park (TNGM) has been dominated by Acacia decurrens after the eruption in 2010. Almost 80% of A. decurrens trees showed stem rot diseases caused by Ceratocystis sp. which may associate with stem wound induced by ambrosia beetle and other physical injuries. The research objective were (1) to characterize the morphological feature, in vitro growth, and ability to adapt, colonize as well as to infect akasia, jabon, sengon, melina and jati sedlings, (2) to evaluate the status of stem rot disease in TNGM demonstration plot. Laboratory work was conducted in order to study the morphological feature of the fungus, in vitro growth on PDA media, and to evaluate its compatibility to growth, colonize, and infect on 5th month seedling of akasia, sengon, jati, jabon and melina. Field monitorings were conducted from February to August 2014 at the restoration plot (8.4 ha) at 8% sampling intensity. Disease status was evaluated in order to ascertain the disease incidence and severity of stem rot disease at the demonstration plot area. Two Ceratocistys isolates found from the hill (B) and valley (L) had similar characteristics on morphologic features i.e. cream color, 20 to 22 cm2 colony size at 14 days growth in PDA media, having both cylindrical and barrel shaped conidia. The other characteristics of the Ceratocistys were an ability to growth, to colonize, and to infect akasia, sengon, melina and jabon, except on jati. The status of stem rot disease was ranged from highly common to widespread (disease incidence = 54%-100%) as the disease severity status was ranged from low to severe (disease severity = 15%-67%). |
