Penyakit karat pada Acacia mangium Willd.

The study was aimed at observing the anatomy and morphology of the obligate rust fungi, Atelocauda digitata G. Wint. which attacked Acacia mangium phyllodes in the seedbed. The study was conducted in the nursery and Laboratory of Forest MicrobiologyResearch Group, Forest and Nature Conservation Research and Development Centre, Bogor for three months. Microscopic observation was conducted by seting microtome-based permanent slide of the attacked phyllodes. Comparison was made between healthy and diseased phyllodes. Macroscopic observations showed that morphologically, theinitial symptom was characterized by green to yellow necrotic spots that turned to brown. The symptom became more severe and eventually might kill the seedlings. Anatomic observation showed that the formation of healthy cells adjoined in regular formation, whereas those of diseased cells were irregularly formed and swollen with chloroplast distribution almost in all part of the tissue. The results showed that of all the five spore stages of the fungi, three were found in A. mangium observed, including picniospores, urediospores and teliotospores. The other two stages which were not found were aecidiospores and bacidiospores. Application afselective fungicide at nursery level and selection of resistant provenance wouldmininlize the disease.
