Abstract

ABSTRAKSclerotium rolfsii merupakan salah satu jamur patogen yang menyebabkan beberapa penyakit pada tanaman, seperti busuk batang, layu serta rebah kecambah. Jamur Sclerotium rolfsii menyerang tanaman kacang tanah serta tanaman lain seperti kentang, tomat, kedelai, kubis-kubisan, bawang, seledri, jagung, selada, kapas, tembakau dan tanaman dari famili Cucurbitaceae. Berdasarkan hasil pengamatan di lapangan didapatkan ukuran diameter sklerotia 0,05-2 mm dan bentuk perkecambahan sklerotia dispersif seperti kapas berwarna putih. Ukuran terkecil dari diameter koloni Sclerotium adalah 0,61 cm dan ukuran terbesarnya 1,71 cm sedangkan untuk pengukuran kecepatan pertumbuhan miselium yang terlambat adalah 3,1 mm/hari dan yang tercepat adalah 8,54 mm/hari yang dapat dilihat pada hari kedua dan hari ketujuh penelitian. ABSTRACTSclerotium rolfsii is one of the crop pathogenic mushroom that caused some disease such as stem decay, wilt and sprout collapse. S. rolfsii infects ground peanut plant other crops such as potato, tomato, soy, cabbage, onion, celery, maize, cress, cotton, tobacco and the relatives of Cucurbitaceae. The measurement showed that the diameter of sclerotia was 0.05-2 mm which formed dispersive germination and appeared as white chromatic cotton-like shape. The smallest diameter of sclerotium colony was 0.61 cm and the largest was 1.71 cm while the slowest and the fastest growing speed of mycelium was 3.1 mm/day and 8.54 mm/day, respectively, which observed at the second and the seventh days.
